How should white radish be fertilized? What should I pay attention to?

White radish is one of the common crops and vegetables in our daily life. White radish can be boiled or eaten cold. White radish is not only delicious, but also very nutritious. It is rich in vitamins and is very beneficial to people's health.

In recent years, more and more people have begun to pay attention to health care. Eating white radish can add vitamins to the body, and the effect is very good.

However, many newly planted white radishes are sparse and of low quality. White radish is particularly important for fertilization, and it needs to master certain fertilization skills. The following small series will introduce how to fertilize white radish in order to make high yield and high quality.

1, Fertilization Principles In view of the problems existing in radish production, such as imbalance in the proportion of nitrogen, phosphorus and potassium, unreasonable application period of phosphorus and potassium, obvious insufficient application of organic fertilizer and insufficient attention to the application of trace elements, the following fertilization principles are put forward:

(1) According to the soil fertility conditions and the target yield, optimize the amount of nitrogen, phosphorus and potassium fertilizers, paying special attention to moderately reducing the amount of nitrogen and phosphorus fertilizers and increasing the amount of potassium fertilizers;

(2) The content of effective trace elements such as manganese, zinc, boron and molybdenum in calcareous soil in northern China is low, so attention should be paid to the supplement of trace elements; When the acidification of vegetable fields in south China is serious, acid soil conditioners such as lime should be applied appropriately.

(3) Rational application of organic fertilizer can improve the yield and quality of radish, avoid the use of non-decomposed organic fertilizer, and advocate the application of commercial organic fertilizer and decomposed farmyard manure.

2. Suggestions on fertilization

(1) Application amount of organic fertilizer. The radish (such as four-season radish) with yield level of 1000 ~ 1500 kg/mu can be applied with organic fertilizer of 0.5 ~ 1 m3/mu; High-yield varieties with yield level of 4500 ~ 5000 kg/mu should be applied with 3 ~ 4 cubic meters of organic fertilizer or commercial organic fertilizer 100 ~ 150 kg/mu;

(2) The output level is above 4,000 kg/mu, the nitrogen fertilizer (N) 10 ~ 12 kg/mu, the phosphorus fertilizer (P2O5) 4 ~ 6 kg/mu and the potassium fertilizer (K2O) 10 ~ 13 kg.

(3) The output level is 2500-4000 kg/mu, nitrogen fertilizer (N)6- 10 kg/mu, phosphorus fertilizer (p2o 5)3-5 kg/mu and potassium fertilizer (K2O)8- 10 kg/mu;

(4) Yield level 1000 ~ 2500 kg/mu, nitrogen fertilizer (N)4 ~ 6 kg/mu, phosphorus fertilizer (p2o 5)2 ~ 4 kg/mu, and potassium fertilizer (K2O)5 ~ 8 kg/mu.

For plots prone to trace element boron deficiency, or plots with boron deficiency symptoms in previous years, borax 1 kg can be applied per mu before sowing, or 0. 1% ~ 0.5% borax or boric acid aqueous solution can be sprayed on the leaves of radish in the middle and late growth period, every 5 ~ 6 days 1 time, 2 ~ 3 times in a row.

All organic fertilizers, phosphorus fertilizers and 40% of the total amount of nitrogen and potassium fertilizers are applied as base fertilizers; Topdressing: 60% of the total nitrogen fertilizer is applied twice in the clumping stage and the early growth stage of fleshy roots, and 60% of the total potassium fertilizer is mainly applied in the early growth stage and expansion stage of fleshy roots.
