1. Soil preparation and fertilization
Before ploughing, apply more than 2,000 kg of fully-fertilized farmyard manure, and simmer for 2 to 3 days after ploughing in mid-to-late September to early October, apply 75 kg of ternary compound fertilizer per mu as base fertilizer, and then plow again. . The kneading surface should be flat and thin, and the width is 2 meters. Then soil disinfection and underground pest control.
Second, staged sowing
Listed during the Spring Festival, the sowing period is mid-to-late September; the market is listed after the Spring Festival, and the sowing period is mid-to-late October. Full seeding before sowing, seeding method using acupuncture point on-demand, after underground seeding, spray the soil surface with 600-800 times of new high-fat film, can protect the water-proof evaporation, sun-proof and drought-resistant, heat-preserving anti-freeze, anti-soil layer, suffocation And isolate the source of pests and diseases to increase the emergence rate.
Third, field management
1. Buckle shed and management: Bai Yuchun radish is more suitable for the shed time in the north of the Yangtze River in mid-to-late October. Filming began when the average daily temperature dropped below 10 °C. The variety is more resistant to low temperatures, and the weather is fine after the shed, and the film is released during the day, and the film is covered with cold air or rainy days. Before the New Year's Day, the air was released. After the New Year's Day, the temperature was low. The air should be kept out of the air or not, and the temperature in the shed should be kept between 10 °C and 20 °C.
2. Fertilizer management: The relative humidity in the shed is kept below 70%. Spraying the fruit of the fruit at the right time to make the nutrient transport conduit of the underground fruit thicker, improve the fruit fruit swelling, smooth fruit surface, strong fruit shape, high quality and high yield. In the six to eight-leaf stage, the topdressing is applied once, and the water is applied to the water with a root application + 15 kg of urea per acre. A small amount of weeds can be removed manually.
3. Pest Control. The main pests and diseases are cruciferous soft rot and aphids. Prevention and control of cruciferous soft rot, using 12% agricultural streptomycin sulfate wettable powder per acre 10 million units of water plus 50-75 kg spray and root irrigation; control aphids, spray with imidacloprid.
