Regular watering after planting to prevent surface drought and cracking. When a new leaf grows after 10 days, watering is stopped, rows of cultivating tillage are ploughed, and the water is replenished after 2 to 3 days. After 4 to 5 days, no watering is carried out to carry out seedlings and promote rooting. About 15 days after seedling sowing, 15 kg of urea was applied per acre to promote seedling growth. After the plants are sealed, because the soil is moist, a large number of white roots will appear on the surface and the temperature is appropriate. This is an opportune time to seize high yields. It is necessary to make joint efforts with water and fertilizer, chase the fertilizer once every 7-10 days, and catch 20 kg of urea per mu, so as to ensure that it does not come off. fat. The last time the top dressing is finished is two weeks before harvest. From about 20 days before harvest, spray 0.3% urea + 0.3% - 0.5% potassium dihydrogen phosphate every 3 to 5 days. Before and after the cold dew, the temperature dropped and the growth was slow. The water could be poured once every 10 to 15 days. Spraying 920 for 20 days prior to harvesting, the first time was 30 ppm, and the spray was once again after 3 to 5 days. The concentration was 35 ppm. When the minimum nighttime temperature reaches -2°C, it begins to be harvested for marketing or storage.
