1. Breeding seedlings are planted using precocious, high quality, low temperature and low light tolerance varieties such as Jinghu No.3. The greenhouse is planted in the early spring from mid-November to early December. The facilities include plastic sheds and mulch. The light-matrix seedlings are used to cultivate the seedlings, buried under the electric heating line, soaked and sowed before sowing. The amount of 350-400 g per mu of field is required. 50 trays, 50 to 60 kg of substrate for raising seedlings. 50% of the seedlings were uncovered, and the whole seedlings were loosely ventilated and ventilated, and the 2 leaves and 1 heart period were properly cooled. Seedling age 3 to 4 leaves, seedling height 8 to 10 cm, 30 to 40 days transplanting, 5 to 7 days before transplanting hardening seedlings. Before planting, cultivating and cultivating sorghum, applying basal fertilizer, planting at the beginning of February of the following year, plant spacing 40-45 cm, row spacing 60-80 cm, 1 plant per hole. After planting, fill the living tree water, seal the planting hole, and warm the enclosure.
2. After 5 to 7 days of field management, the greenhouse is not ventilated, and the live trees are promptly ventilated, dampened, and cooled. Watch for cold weather during wintering. In mid-April, the greenhouse was removed. The outside temperature exceeds 18°C, and the top film of the greenhouse is removed to remove the skirt film. Fertilizer and water management should be applied early and diligently, and the root melons should be used in combination with watering. Mushi 500 kg of livestock manure plus 45% potassium sulfate compound fertilizer should be used for 10 kg, and 1 fertilizer should be collected once per harvest. Flowering period do a good job of artificial pollination or hormone treatment. During the harvest period, the old leaves, diseased leaves, and excess male flowers in time are removed to reduce nutrient consumption and improve ventilation and light transmission conditions.
3. Diseases and pests control diseases are mainly gray mold, sclerotinia disease, can be used 50% procymidone WP 800 times or 40% Fuxing (fluorosilicon) EC 5000 times liquid. Insect pests mainly include aphids, whiteflies, and tea astragalus. 70% precious (imidacloprid) water dispersible powder 5000 times solution plus 0.5% abamectin 1000 times solution can be used for prevention and control.
