In order to help the people grow good white radish, we will introduce the points for the cultivation of white radish in the autumn so as to provide reference for the farmers:
1. Site preparation and preparation: The radish is a cruciferous crop, which can not be replanted in the same crop as the previous crop. Radish roots are thick and should be grown in sandy loam soil with thick, fertile and well ventilated soil. Planting plots should be ploughed up to 20 cm deep and ploughed and leveled to facilitate the growth of radish rhizomes.
2, ridge and fertilization: radish acres of high yield, soil nutrient water consumption, ridge planting conducive to drainage and promote root enlargement; to ensure the quality of radish, fertilization to farm fertilizer as the main fertilizer, fertilizer supplement. Mu Shi farmyard fertilizer 1500 kg, 20-25 kg of calcium, or nitrogen, phosphorus and potassium ternary compound fertilizer 60 kg.
3, selection of varieties: varieties can choose the Japanese series of Kobayashi, disease-resistant state, but also with the local self-cultivation species. However, the seeds must be new. The seeds newly produced in the year can prevent radish twitching.
4, timely sowing: premature sowing, radish swelling more rain, heavy disease, poor quality. At present, the white radish has been planted in the best period, and the masses should take care of the emergence management. White radish sowing use sowing or open seed sowing on demand, the spacing is generally 3030 cm is more appropriate, about 200 to 250 grams of seed per acre.
5, Dianmiao Dingmiao: When the radish seedlings grow to 2-3 true leaves when the time to conduct the seedlings, leaving 2 per hole; when the length of the five leaves to the true seedlings, each hole can only stay one, so that individual seedlings robust Grow.
6, top dressing management: 30 days after the emergence of radish, can be used when the soil moisture is good outside the root chase fertilizer. Urea use 5 to 10 kg per acre, using acupuncture points. When the weather is dry, 0.3% potassium dihydrogen phosphate can be sprayed on the leaves, which is beneficial to root expansion and increase production.
7, pest control: radish disease is mainly black rot, mosaic virus disease, lack of prime disease, early onset with 58% metalaxyl manganese zinc, 72% of agricultural streptomycin, 15% of Bacmid Bac 70% A Chitobuzu and other agents are sprayed or sprayed on water, and sprayed twice every 5-7 days. A total of 2 pests are harmful to the radish, including yellow song strips, aphids, cabbage caterpillars, and diamondback moths. Cypermethrin 2000 times solution control, interval 7 days, even prevention twice, prohibit the use of high toxicity and high residual pesticides; radish deficiency disease should be 30 days after the emergence of acres of application of 1 kg of borax and zinc fertilizer, 0.2% of the initial application of root expansion Borax solution.
8, timely harvest: When the radish individuals grow to 1.5-2 kilograms, the old leaves of the ground yellow, that is, radish harvest time. If the growth period is too long or suffers from frost damage, the quality of the radish should be prevented from deteriorating or even becoming irritating.
