estate wholesale jewelry 1. Temperature: Watermelon has high requirements for temperature, and within 24-30 ° C. Watermelon does not like low temperature, so it should not be lower than 14 ° C. However, if it is raised in the greenhouse, you don't need to pay attention to the temperature, it is more appropriate.
2. Watering: The drought tolerant of watermelon is relatively strong, but it is not flood -resistant. Therefore, just replenish water in an appropriate amount. Note that you must not accumulate water. During rainy days, it is necessary to drain it in time, or take measures in advance to cover the rainwater.
3, light: Watermelon is a very happy type. To ensure sufficient light, its output can be guaranteed. Generally speaking, in its growth period, there is no need to cover it for it.
4. Fertilization: The demand for fertilizer in watermelon is also high, especially during the flowering period. At the same time, pay attention to the types of each nutrition, and do not only pay attention to one element. However, in general, the demand for nitrogen is the most.
Pucting data
Note
1, potting pots: If it is a potted plant of watermelon, then it is very important to change the soil. You can prepare the appropriate soil yourself, you need to meet the requirements of loose, good drainage performance, more nutrition, and pH value of 5-7. Change the pot after selecting the soil. Even if you don't change the pot, you need to loosen the soil.
2, disease: there may be "leaf blight", which is the most common in summer. Multi -bacteria can be treated and ventilated. There are also "white powder disease", threatening leaves and flowers. It can be treated with Bacteria.

jewelry wholesale malaysia The cultivation of watermelon cultivation in small arch sheds is now introduced as an example:
The structure and performance of small arch sheds
The small arch shed should choose north and south, covering 1.4-1.6 meters wide. 60 cm wide, 40 cm deep melon groove, after fertilizing the soil fertilizer mix and make 60 cm wide, 10-15 cm high tortoise back -shaped cultivation bed, each side of the bed forms a watering groove of 30 cm wide , Each on the outside of the groove is a 20 cm height 20 cm wide pupa, and the 埂 is inserted every 1-1.2 meters to insert 1 piece of 2 meters long, 4 cm wide bamboo sheet to form an arch of about 1.5 meters wide and about 0.7 meters high, about 0.7 meters high. The rack is buckled with a 4 -meter wide film on the frame. Bamboo pieces per mu 240-260 pieces. 0.014 mm agricultural membranes are about 7.5 kg or 0.03 mm agricultural membranes are about 16 kg, and 0.005 mm membrane is about 2.5 kg. The minimum temperature at the beginning of the year of the structure can be stabilized at 5 degrees in early April, which can meet the requirements of the watermelon slow seedlings.
The cultivation of grafting seedlings
The simple greenhouses with heating facilities in production are mostly used to cultivate grafting seedlings, use pumpkin or gourd as rootstocks, and adopt a leaning or penetration method. The seedlings are about 40 days. 1. The seedbed is set to the north and south of the seedbed, 1.2 meters wide, and requires a flat bottom. 2. The preparation of nutritional soil for nutritional soil requires loose, fertile, water preservation, fertilizer, and urgent fungus eggs. Generally, 2 parts of fertile pastoral soil plus 1 part of high-temperature fermentation of high-temperature fermentation and rotten organic fertilizer, and then add 0.5 kg of dilate or 1 kg of compound fertilizer according to each cubic meter, 50%multi-bacterial spirit 3-4 two, 3-4 two, 3-4 two, 3-4 two, 3-4 two, and 3-4 two. 50%phosphorus 1 phosphorus is 1 two. After fully mixing, load it into a nutritious bowl with a diameter of 8 cm high. Put the water through the nutrition bowl a week before the broadcast. 3. The greenhouse disinfection before sulfur powder 2 kg/mu duves of the enemy is 0.2 kg/mu, mixed with sawdust for 24 hours. 4. Seed treatment (1) Blackseed pumpkin black seeds and pumpkin seeds are very dormant, and the seed germination rate of that year was only about 40%. You need to break the dormant with gibberee. The specific method is to soak the seeds with warm water for 1-2 hours, wash the debris, and then soak it with 150-200 ppm. If you use Chen seeds in the previous year, you can directly soak the seeds, and the planting time can be 12 hours. (2) Gourd Seed Gourd Seed Seeds thick skin, difficulty in absorbing water, slow germination of the seeds, incomplete sprouts, and low germination rate. It can be treated with hot water scalding. First, use
The watermelon carving picture set (20 photos) cold water immersion without seeds, and then pour the hot water from 80-90 degrees to continuously stir in one direction, so that the water temperature is reduced to 70-75 degrees Keep it for about 1 minute, and finally pour cold water to reduce the water temperature to 20-30 degrees. Continue to soak the seeds for 24-36 hours. You can also use 100 ppm gibbererin treatment by reference to the pumpkin seed treatment method; Use 50%multi -bacterial or Tapin 500 times liquid to soak for 30 minutes and remove and clean it for 6-8 hours in warm water; the other is to cast with 80-90 degrees hot water for 3-5 seconds and then add cold water to make the water temperature. Fall to about 55 degrees, soak for about 10 minutes, and drop to 20-30 degrees soaking for 6-8 hours. No matter which method is used to deal with the seeds, it must be dried or wiped off the excess water of the seed skin before germination. After the waterless film is wrapped in the waterless film, put it in the 28-30 degree environment to prevent the germination of the seed in the kernel. The lack of oxygen affects seed germination. 5. Sowing: (1) Use pumpkin as rootstock. Pumpkin seeds are soaked in germination. After germination of watermelon seeds, two capsules are sowed in the nutrient bowl at the same time in the nutrition bowl and the spike seeds were sown each. The temperature of the day is 30-35 degrees, and at 18-22 degrees at night, ensuring soil temperature above 18 degrees, after the seedlings fall to about 25 degrees during the day, and 15 to 16 degrees at night. You can sow the watermelon seeds after germination. Watermelon seeds are sown in the sand table. Before sowing, soak the sand with boiling water. After cooling, sprinkle the watermelon seeds about 1 cm and sow, cover the soil for 1 cm, and the cover film moisturizes and increases. The seedlings of the sand table for about 5-6 days of the greenhouse are about 5-6 days. During the grafting period. Watermelon
6. Grafting: (1) Pumpkin and watermelon are connected: Pumpkin seed Ye Ping shows up the growth point when showing the heart, and use a blade at a blade of 45 degrees at 0.5-1 centimeters under the leaves. The thick 2/5-1/2, the incision is about 1 cm long. At the same time, the corresponding part of the watermelon scion is obliquely cut upwards, and the depth is 1/2-2/3 of the neck thickness. The length of the incision is the same as that of the rootstock incision. The scion incision is embedded in the incision of the rootstock's stem, so that the interface of the two is closely fitted together, and the fixed interface is fixed with grafting. After about seven days, the interface healed, cut off the root of the scion, and removed the grafting clamp after 10-15 days. (2) Use the gourd as the roof of the ate wood: remove the gourd top buds and true leaves when grafting, leave only two pieces of seed leaves, and then use a bamboo stick with 6-8 mm slopes with a sharp tip of the watermelon seedlings, the slope of the slope, and the beveled surface. Insert the direction of the gourd leaf veins and the gourd stem about 45 degrees, and the tip of the bamboo stick is just exposed. Put the watermelon seedlings at 8-10 millimeters under the cotyledon, cut the stems with a blade, the length of the cut surface is 8-10 mm, and the bamboo sticks are pulled out quickly and inserted the watermelon scion into the gourd rootstock. The scion -leaf crosses the shape of "ten". 7. Management after grafting: After grafting, cover the small arched sheds to moisturize in time, and cover it with a shade net or analog. The first three days did not ventilate, 25-28 degrees during the day, 20-22 degrees at night, not less than 18 degrees. The relative humidity of the air in the small arched shed remains above 95%. After three days, the ventilation and gas replacement was gradually increased to shorten the shade time. After about 12 days of grafting seedlings, the temperature can be reduced to 24-26 degrees during the day and 16-18 degrees at night. Pay attention to the germinated side buds of the rootstock in time. Spray drugs to prevent diseases. Low -temperature refining seedlings 3-5 days before planting, increased the amount of wind during the day, 22-24 degrees during the day, and fell to 13-15 degrees at night to enhance the adaptability of seedlings to the environment in the small arch shed after planting.
Prefalting before planting
1. Fundamental fertilizer: combined with cultivation of 2-2.5 square of fermented chicken manure per acre or 6-8 square of high -quality circle manure Tunger and circle dung are mixed with high temperature fermentation together, and the organic fertilizer of high temperature fermentation is not easy to burn seedlings), 30-40 kg of dibar ammonium, 30-40 kg of potassium sulfate, 10-15 kg of urea or 25-40 ammonium carbide 25-40 In kg, micro -fertilizer is applied or sprayed according to the absence of prime. 2. Make 畦, 2, and buckle shed. In late March, the sunny days were selected and required in time. 7-10 days before planting, covering the ground, buckling small arched sheds, baking ground, and heating up.
In planting
1 1. Planting period: Shi City and surrounding counties and cities are generally at the end of March and early April. When the temperature in 5 cm in the small arch shed is stable above 12 degrees, it can be selected from the wind and sunny day. Looking at it at this time, the willow trees are germinated with poplars. 2. Plant density: Two rows of planting beds in each cultivation bed, the plant spacing is not less than 0.7 meters, and 650-700 plants are planted per mu. Watermelon flowers
This Point -opening or melon shovel on the covered mulch is perforated directly on the covering ground, and the water planting seedlings are performed. Finally, the membrane holes are tightly sealed with soil to cover the small arched sheds in time.
In after planting
1. Temperature management: (1) Planting -from planting to melon seedlings from 5-6 leaves from upright growth to the period before the growth period, about 13-15 days Essence The first three days after planting generally do not let go of the wind to promote seedlings. After slowing the seedlings, we can gradually increase the amount of air release every day to 2 pm to achieve cooling, humidifying, improving the conditions of light, reducing the growth rate of plants, improving the resistance of anti -inverse, and reaching thickness of the leaves, neck thickness, and strong root system. (2) Tuanshi — seat melon: At this stage, it has entered late April, and the evening cream has passed. Generally, freezing damage is needed. The root system and stems and leaves of this period grow rapidly, which is easy to grow. Therefore, the wind should be enlarged in the morning and noon, and the fascinating membranes should be used to promote the reasonable distribution of nutrients at night, and the fruits will be sat early. 2. The whole way of pruning: Generally, the three vines are used. When the main vine grows to 30 cm long, and the branches of the stem base reaches 5 cm, each plant is selected to leave two strong side vines with uniform length, and the extra side vines are removed early. Generally, the second or third female flowers are selected. When the main vines can't sit still, the side vine flower can be selected. Generally, the excess side branches of the fruits are removed early, and the side branches of several sections after the fruits can leave 3 to 6 leaves to tip to increase the leaf area and increase yield. 3. Fertilizer and water management: In the case of planting water, when the main vine grows about 50 cm, it can be combined with 5 kg of urea per acre and 10 kg of potassium dihydrogen phosphate. When the young fruit grows as long as the eggs, it is rushed into 15 kg of urea per acre with water and 20 kg of potassium dihydrogen phosphate. The fruit bowl mouth is 10 kilograms per acre in the size of the bowl mouth, and 15 kg of potassium dihydrogen phosphate can be sprayed with leaf surface fertilizer to prevent premature stems and leaves. 4. Artificial auxiliary pollination: The pollination time is 7-11 in the morning, remove the petals that are open that day, and gently apply the pollen to the blooming female flowers. Pay attention to it in operation to prevent deformed fruits. 5. Methods and key technologies for the second result of watermelon: There are two methods, one is to cut the vine regeneration, that is, after the first stubble melon is set, pay attention to the selection of 3 new vines born in the base. The rhizomes are 30 cm to cut the old vines and use the new vine results. The other is the new shoots, that is, in the late stage of fruit growth, the new vine fruits from the top of the main and side vines are used. Generally, it can be blooming and sitting fruit for 7-10 days. This method is simple, but the fruit is high, the fruit shape is small, and the output is low. The key technology is mainly to do a good job of preventing disease in the first stage of the melon melon, leaf surface spray fertilizer, strictly prevent premature aging of the stems and leaves, clean the countryside in time after picking melon, pour roots with root roots and pursue pursuit of watering, and promote the healthy growth of the new man.
M small gift watermelon cultivation technology
. The cultivation season is highly adapted by small watermelon, and the temperature can grow normally above 14 ° C. Different cultivation techniques can be sown from mid -January to late July, and can be harvested in May to October. Early spring protection land cultivation: Sowing seedlings in mid -late February, 35-40 days of seedlings, seedlings are used to raise seedlings, and it is planted in the greenhouse in mid -April and was listed in early June. Naked land cultivation in spring: sowing from late March to late May, about 30 days of seedling. The protection of seedlings, planted in naked land or covering small arched sheds after the final cream. Summer protection place is delayed: sowing in late July, about 20 days of seedling. In early September, the shed film was covered, and the heating grass curtain was covered in the early days, and it was listed around October. 2. Preparation of sowing nutritional soil: There are many ways to prepare nutritional soil. Commonly used 2/3 grass carbon soil plus 1/3 of the field soil that has not been planted and mix well, or 1/3 of the rotten farmhouse fertilizer plus 2/3 field soil soil Essence Each soil plus 2 kg of calcium phosphate, disinfected with 800 times the bacterial liquid, or fumigated with formaldehyde. Soaking seeds to urge buds: It can be sterilized with 55 ° C warm water and continuously stirred until the temperature of the water drops to about 30 ° C. After soaking for 4 hours, clean the seeds, and then use a wet woolen wrap to tighten the germination in the environment of about 30 ° C. Sowing: The day before sowing, the 800 -fold methylobujin fluid was used to pour the seedlings. When the seed buds grow to about 0.5 cm, sowing in the seedling plate should be placed flat, the sprouts are upward, and the top -covered nutrient soil should be covered with fine nutrient soil. 1.5 cm thick, and pour the seedlings with 800 times nailobobadin solution, and keep the temperature at 25-30 ° C to ensure that the seedlings are neat. The temperature is kept at 18-28 ° C after the seedlings. Do not wet the seedbed. Early spring should prevent frost damage and ensure sufficient light. In summer, high temperature should be prevented. Third, field management planting: Generally, multi -vines and fruit and vines are cultivated, with a row distance of 60-80 cm × 180-200 cm, and 530-730 plants can be planted per acre. It can also be cultivated with a standing grid, with a row distance of 50 cm × 100-140 cm, and double -row planting. Fertilizer: mainly based on bottom fertilizer, supplemented by topdressing. The bottom fertilizer should be composed of 53-66 kg compound fertilizer and 2670 kg per mu. In the future, the entire fertility period is mainly "two water and two fertilizers", that is, vine fertilizer. After one week of planting, nitrogen fertilizer is mainly used for irrigation; melon fertilizers are mainly used for phosphorus and potassium after one week. Remove fruit: small cause and effect, to reach higher yield, you should use multiple vines and fruit cultivation. Generally, a main vine and 3-4 vines are retained, or the vines are not rectified. The rest can be retained with two stubble melons. Prevention and treatment of pests: Small watermelon varieties have strong disease resistance compared to large watermelon varieties. Generally, diseases are vine blight, withered disease, viral diseases, anthracnose, etc. The best prevention and treatment of diseases and insect pests is best performed once every 7-10 days.
The watermelon harvesting high -yield cultivation technology
M multiple harvested technology cultivation in the greenhouse can be cultivated in watermelon, which can be harvested 5 to 6 times from May to the end of October, with an average of 7,500 kilograms per mu. Essence The varieties are selected from early ripening, disease resistance, low temperature resistance, and strong early watermelon varieties such as early goodness. The cultivation of Zhuangmiao Nanjing area is generally sown in mid -January, and the nutritional bowl of the electric heatingbed hotbed is used. In the greenhouse, it depends on the number of seedlings with a width of 1 meter and a depth of 25 cm deep. The inner paving film, sprinkle fine soil, straw and other objects, laid electric heating wires on it, and discharge nutritional bowls. Sowing the germination to 80%of the seeds is sown, and 1 capsule is broadcast per bowl. After sowing, it covers 0.5 to 1 cm thick, covering the ground, and a small arched shed. Cover the grass curtains on the small arched shed at night. The temperature of the bed was kept at 30 to 32 ° C during the day, and the night was maintained at 20-25 ° C. 70%of the melon seedlings were removed after the land was unearthed. After Qi Miao, the small arched sheds were properly opened to cool down. Gradually cool down the seedlings 1 week before transplanting. Applying 2,500 kg of rotten organic fertilizer per acre before the planted planting, 100 kg of rotten cake fertilizer, 10 kg of urea, 50 kg of overlapping calcium phosphate, 15 kg of potassium sulfate, or 100 kg of compound fertilizer per acres. Combined with fertilization, 3%phosphorus particle particles and 50%multi -bacterial wettable powder are 2 kg per acre. One month before the planting, the whole land was made, and the 5 -meter -wide greenhouse was made of 2 畦, 2 meters wide, and 30 cm wide operating groove in the middle. From late February to March, it is selected to be planted in the morning in the morning. Each row is planted, the plant spacing is 80 cm, and about 330 plants are planted per acre. After planting, water the water, cover the ground after the water seeps, a small arch shed on it, and cover the grasshopper on the small arched shed at night. The management within 10 days after the temperature and humidity management is mainly thermal insulation. The temperature of the shed temperature during the day is maintained at 25-32 ° C, the night is maintained at 18-20 ° C, and the shed temperature exceeds 35 ° C appropriately ventilated and cools down. Increase the ventilation volume appropriately after sitting melon. The temperature of the melon expansion and mature period is kept at 25-32 ° C during the day, and the night is maintained at 15-20 ° C. The small arched shed was withdrawn in mid -April. After the temperature rises in May, pay attention to ventilation and gas, and open the skirt and top membrane to cool down at noon. Remove the edge film in summer and leave the top membrane and replenish water. In August, the temperature was high, and the amount of plant transpiration was large, and moisture and temperature should be scientifically controlled. The plant adjustment adopts the three vines. When the main vine is 60 cm long, two strong side vines are selected at 3 to 5 knots, and all the remaining sides are removed to reduce nutrient consumption. After the melon is steadily removed, the weak branches, sick branches and old leaves, and sick leaves are removed to facilitate ventilation and light transmission. Choose the soil to press the vines in a sunny afternoon. Flower and fruit manages melon eggs in the size of 1 or 2 melons for each plant. When the melon diameter is 12 cm, the watermelon
It removes the deformity and excess melon, leaving an average of 1 melon per plant, and 330 melons per acre. Turn the melon once 15 to 20 days after sitting melon, and use dry straw or fruit pad. When the first batch of melon 7-8 matures, the second batch of melons are selected on the new hair vines. The amount of melon is determined according to the long potential of the melon. The temperature in autumn is high, and the salary should be properly pushed back. Generally, 2 melons are selected after 20 knots. The third and fourth batch of melons should be properly removed to ensure the quality of melon. Pay attention to the prevention and treatment of watermelon swelling, rising disease, withered disease, leaf blight, frostmo, anthracnose, white powder and aphids, red spiders and other diseases and insect pests. The first batch of melons will be harvested 37 to 40 days after the female flowers are opened in a timely manner, and they will be harvested once every 30 days. When the first stubble melon is picked, the two stubble melons have been sitting melon. Be careful not to pull the vine too much.

Autumn watermelon is a watermelon that sowing in summer and harvesting in autumn. Planting autumn watermelon can extend the supply season, increase the types of fruits and fruits during the Mid -Autumn Festival and National Day, enrich the market, and increase farmers' income. Autumn watermelon is generally produced about 2,000 kilograms per mu, and the output value can reach more than 1,000 yuan.
1. Select good varieties and finely neatly. The choice of varieties is related to the output of autumn watermelon. High temperature and drought in autumn, you should choose delayed varieties. In addition, according to consumer habits, choose different varieties. Land can choose mountain rice fields with loose mountains or soil, deep soil layers, and convenient discharge irrigation. 7 to 10 days before sowing, the recovery and recovery of the rake was opened as a trench, and the noodles were flattened.
. Sowing in time and reasonable planting. The sowing period of autumn watermelon is relatively strict. The city should be sown in mid -July in the middle of July. The sowing is preferably to promote the live broadcast of germination, which is conducive to improving the resistance of melon seedlings. Show 1 centimeter deep and pour water. After sowing, the acupoint surface is covered with weeds to keep the temperature and reduce the temperature. Immediately after emergence, weeds are unveiled to avoid causing high -footed seedlings. Autumn watermelon grows fast in the early stage, less branches, and the output of single seedlings is low. The planting density is larger than spring watermelon. Generally, 900 to 1,000 plants are planted per mu.
three, scientific management, promote the fruits. ① Prevent high temperature damage. After sowing, weeds should be covered on the surface to cool down to cool down. After emergence, watering should be pursued multiple times in the evening and early morning to promote growth. ② Toppy. The temperature of the autumn watermelon is high and the base fertilizer is sufficient, which can easily cause long -term pruning. The second and third male flowers are usually used in double vines, each fruit. After sitting, the top 10-15 before the melon festival controls the growth of melon seedlings and promote the growth of watermelon. ③ Watering and fertilizing during puffing. After the autumn watermelon is fruits, it is the high temperature and dry period of our city. At this time, it should be pursued in the evening to ensure that there is enough water and nutrients. ④ Turn melon. In order to keep the color of the melon skin uniform and eliminate the generation of yellow and white, it should be rolled 3 to 4 times after the watermelon is fruit. The melon should be carried out in a sunny afternoon to avoid hurting the stems and leaves of the melon; each time the melon is turned in the same direction, and the angle should not be too large, generally 30 degrees to 50 degrees. In addition, the first four or five days of harvesting should be raised to make the fruit development complete.
