At present, it is the season for planting autumn radish in the northern part of Baoding. In order to timely plant and ensure high quality and high yield, the key points of its cultivation techniques are as follows. 1. Land preparation and ridge Before sowing, apply 800-1000 kg of decomposed organic fertilizer per mu, or farmer's fertilizer (for example, chicken manure) 3000-4000 kg, diammonium phosphate 15 kg, and potassium sulfate 10 kg. In order to control underground pests, 4 to 5 kg of phoxim granules are applied per acre. Second, seed selection Choose varieties that are resistant to disease, high quality, high yield, strong resistance, good commodity, and stable traits, such as 301, Jiemeixia, etc. Third, sowing In the northern part of Baoding, the autumn radish should be sown in August, and the ridges should be ridged before sowing. The ridge width is 25-30 cm, the ridge height is 15-20 cm, and the ridge distance is 30-35 cm. The amount of seed used per acre is 150 grams, the hole is planted, 1 capsule/hole, the seedling distance is 13-15 cm, and the soil is covered with 1.5 cm after sowing, with a slight suppression. Fourth, field management Autumn radish is in the high temperature and rainy season in the early stage of growth. It should be timely cultivating and weeding. The first cultivating should be shallow after the seedling is fixed. After the cultivating, the cultivating can be properly deepened, but the roots cannot be injured. During the expansion period of fleshy roots, the soil is kept moist. Generally, water is poured 2~3 times to prevent dryness and wetting. In the early and middle stages of fleshy root expansion, 10 kg of urea is applied per mu, and quick-acting nitrogen fertilizer should not be used within 20 days before harvesting. It is not suitable to use ammonium bicarbonate. In the middle and late growth period, 0.3% calcium chloride and 0.2% boric acid solution can be sprayed 2 to 3 times to prevent calcium deficiency and boron deficiency. At the same time, foliar potassium dihydrogen phosphate is sprayed to increase yield and quality. V. Pest Control In the early stage, pests were the main focus, and the focus was on the control of aphids and yellow-striped beetles. The focus of the later prevention and treatment is downy mildew and viral diseases, and the growers pay attention to timely spraying and prevention. Sixth, harvest Radish is generally fully harvested after the fleshy roots are harvested. Disclaimer: Some articles on this website are transferred from the Internet.
