I. Choosing and making land preparations 1. Guadi Choice: Choose a paddy field with convenient drainage and irrigation, well-ventilated, low groundwater level and no melons in recent years. For rice and vegetables, it has good air permeability, medium fertility, and pH of about 7.0. 2. Soil preparation: The land is ploughed with two plows, deep plowing and hoeing. After the land is well-grounded, the plutonium is made 3m wide (even in ditch), the plutonium is 0.2-0.3m high, the ditches are 0.3m wide, and the diorama is ditched. Should be widened and deepened to 0.5m and 0.4m respectively. Second, the selection of seedlings 1. Select seeds: Select good melon seeds, and then melon seeds should be sterilized with 70% thiophanate-methyl and new high fat film soaked seeds for 2 to 3 hours. Then wash the disinfected seeds with clean water and put them evenly. In the sand dish, cover with wet gauze or wet grass with low germination, and the temperature is controlled at about 30°C. After 1 to 2 days, germinating and whitening seeds were picked and sown. The sowing date is arranged in mid-June to avoid flowering and meloning during the rainy season. 2. Seedlings: first prepare a good nutrition soil: 50% rotten pig cow dung plus 50% sand loam not planted melon, plus 0.5% calcium magnesium phosphate broken and mix. The prepared nutrient soil was packed into a 10cm (diameter) 10-12cm (high) small plastic bag to make a nutritional bag. The melon seeds are germinated and then sowed into a nutritional bag. Each bag is sown with a seeding depth of 1 cm and covered with fine sandy soil after sowing. The seedbed should maintain proper moisture, and a new high-fat film should be sprayed to protect the fertilizer. The nursery temperature is controlled at 20-25°C. 3. Disease Prevention and Control: When seedlings and pests are found, they should be sprayed with targeted high-fat membranes for prevention and treatment.
