l. Variety selection The varieties with strong resistance to disease, good resistance to low glutinous and weak light, good quality and good storage in the late growth stage, such as champion, Qiuhua No.2, Luhoutian No.2, etc.
2. Seedlings or live broadcasts in the east warm greenhouse will be planted in late fall from late July to early August; the arches will be planted in autumn in the middle of July in the round-green shed, and nutrient soils should be used to fill in the nursery. Build nursery beds in high dry, well-ventilated areas. Arched nursery in the greenhouse, retaining the top film, surrounded by large ventilation, and appropriate shading; also can build shelter shading seedlings, imminent seedbeds made of semi-high stilts, on the stilts erect bamboo raft arch, height 0.8-1 m Only cover the top of the plastic film or shade net. Germination sowing, each germinate seeded a germinated seed, covered with 1-1.5 cm soil. Seedling temperature is high, and the seedlings are easy to grow, and attention should be paid to enhancing ventilation. In the seedling stage, it is necessary to spray and control the locusts 2-3 times, spraying the crops and weeds around the seedbed to eliminate the insect source. In nursery, shading is generally performed when sunlight is strong before and after noon. When damping-off occurs, 50% of enemy powder can be used to irrigate roots with 500-700 times, and 75% of chlorothalonil powder can be sprayed 600-800 times to prevent diseases. The autumn cultivation can also be broadcast live, live broadcast can reduce the rooting, the virus disease is light, and the seeding period for direct seeding can be 5-10 days later than the seedling raising. The seedling period should be shaded, rain and rain-proof.
3. Fertilize the soil 10 days before planting and colonization. Combined with the preparation of the first 667 square meters of cooked circumfertility 4000-5000 kg, 2000 kg of decomposed chicken manure, 50 kg of superphosphate, 150 kg of NPK fertilizer. The saddle-shaped ridges are made in rows with a row spacing of 60-70 cm and a row spacing of 80-90 cm. In the past, as a greenhouse for melons, it can be disinfected with 1.5 kilograms of enecropine per 667 meters. 20-25 days after sowing, the seedlings can be planted with 3 leaves and 1 heart. After the seedlings are planted, the entire greenhouse is watered and covered with plastic film. Planting 1500-2000 plants per acre.
