1. Soil preparation and fertilization Because muskmelon likes high temperature and multi-sun climate, it should be planted in soil with sufficient moisture, fertile soil and deep cultivated layer; adopt the "ditch fertilization method", generally 1000kg organic fertilizer per 667 square meters, nitrogen, phosphorus and potassium compound fertilizer 50 kg, 100 kg of potash fertilizer, 1 kg of zinc fertilizer, 2 kg of borax. Second, sowing seedlings Put the melon seeds in warm water at 55 degrees, stir for 15 minutes, take them out, soak them in warm water at 25 degrees for 5-6 hours, take out the mucus on the surface of the seeds, wrap them in a damp cloth, and place them in a 32 degrees germination box Inner germination, the seedlings can be sown in about 24 hours (bud length 0.5 cm). Nutrient bowls or plug trays can be used for seeding. After sowing, the temperature of the seedbed is controlled at about 33 degrees, and after unearthed, the temperature is controlled at 25-28 degrees. When the seedlings grow to 3 -4 leaves and 1 heart can be planted. 3. Planting, pruning and branching Colonization: Cultivate 1800-2200 plants per mu, "hanging vine cultivation" plant spacing is 25-30 cm, row spacing is 40-60 cm, and the ridge height is generally 20-25 cm. After planting, it must be covered with plastic film; "climbing cultivation" plant spacing is 30- 35 cm, line spacing 60 cm. Pruning and branching: (1) Single vine hanging seedling pruning method When the main vine grows to 40 cm long, the vine hangs, and it grows to about 30 leaves. The child vine with 8-12 leaves is the fruit-setting vine. After the fruit is set, 2-3 leaves are left for the head, and each plant leaves 2-3 fruits, 1-7 One leaf and 13-25 leaf vines are removed, and 26-30 leaf vines are used for the second crop. (2) Climbing ground pruning method Top vines with 4-5 leaves and leave 2 vines with 8-10 leaves for topping, each vine has 5-8 leaves for grandson vines, each vine can hold 2-3 fruits, and the grandchildren retain 2- 3-leaf topping. 4. Management of pollination and fruit setting period Pollination is mainly based on "artificial assisted pollination". "Artificially assisted pollination" refers to pollination with the male flowers of this plant within 2 hours of the day when the female flowers bloom. When the melon fetus grows to the size of the egg, choose a sunny morning combined with small watering, and apply 10 catties of urea and 20 catties of potassium sulfate fertilizer per acre of land, or topdressing fertilization, the whole fruit swelling period can be watered and topdressed 2-3 times , Stop watering and top dressing 7-10 days before harvest. Five, two and three crop management Melon generally can produce 3-4 stubbles continuously in winter warm sheds and large arch sheds. In early spring, small arch sheds and open field cultivation can produce 2 stubbles. The specific methods are as follows: Hanging vine type: After the first crop of melon fruit expands, leave a second crop of 25-28 leaf vines, and three or four crops can leave fruits at the top vine at will. Climbing style: about 15 days after the first crop of melon sets fruit, the grandson vines can set fruit in the post-vine position. Tip: Regardless of the cultivation mode, the more fruits are left, the smaller the weight of a single melon, and vice versa. When the farmers keep the fruits, they can keep the fruits appropriately according to the amount of fertilizer they use. Commodity, so the yield per mu will be higher. Six, pest control Generally, the policy of "prevention first, comprehensive control" is adopted, and it is required to spray commonly used broad-spectrum fungicides, such as carbendazim, chlorothalonil, thiophanate methyl, etc., every 7-10 days from the seedling stage. The following diseases can be controlled as required. 1. Vine blight: Use 50% carbendazim wettable powder 3 times solution to coat the affected area. 2. Powdery mildew: use 50% polysulfur suspension. 3. Downy mildew: spray with 25% switzerland and 58% metalaxyl mancozeb. 4. Aphids and leaf miners: spray with lambda-cyhalothrin 25 g/l (emulsifiable concentrate), 1.8% abamectin emulsifiable concentrate.
