1. Fostering seedlings Choose early maturing, high quality, low temperature and low light varieties, such as Jingjing No. 3. Early spring cultivation in greenhouses is generally sown from mid-November to early December. The facility is a greenhouse with a mulch and a mulch. The trays are lightly seeded and seeded, and the electric heating line is buried. Soaking seeds and germination before sowing, 350-400 grams of seed per acre. 50 trays, 50 to 60 kg of seedling substrate. 50% of the seedlings were removed from the mulch, and the whole seedlings were ventilated and damp, and the 2 leaves and 1 heart stage were appropriately cooled. Seedling age 3 to 4 leaves, seedling height 8 to 10 cm, 30 to 40 days transplanting, 5 to 7 days before transplanting to refine seedlings. Before planting, deep ploughing and hoeing were done, and the base fertilizer was applied. The planting was carried out in early February of the next year. The plant spacing was 40-45 cm, and the row spacing was 60-80 cm, one per hole. After planting, pour enough water to seal the wells, and seal the shed to increase the temperature. 2. Daejeon management 5 to 7 days after planting, the shed is not ventilated, and the living room is timely ventilated, damp and cool. Pay attention to the cold weather during the winter. In the middle of April, the shed in the greenhouse was removed. The outside temperature exceeds 18 ° C, and the apex of the greenhouse is removed to remove the skirt. Fertilizer management should be applied early, diligently applied, rooted melons and flowers, combined with watering, acre of human animal manure 500 kg plus 45% potassium sulphate compound fertilizer 10 kg, after each harvest 1 time top dressing 1 time. Do a good job of artificial pollination or hormone treatment during the flowering period. During the harvesting period, the old leaves, diseased leaves and excess male flowers are removed in time to reduce nutrient consumption and improve ventilation and light transmission conditions.
