Boron fertilizer can be applied to radish air-proof core application of boron fertilizer in radish

Radish needs more boron, and the application of boron fertilizer can increase yield by about 15%, and can be hollow-proof. The specific application methods of boron fertilizer are as follows:

Radish

As a base fertilizer, when sowing radish, mix 300 grams of boric acid or 500 grams of borax per mu into 5: 10 kilograms of dry fine soil, mix well and sift, then use it as base fertilizer and apply it into ditches or holes. The dry fine soil mixed with boron fertilizer and radish seeds can also be mixed well and sprinkled into the seed ditch and seed hole.

To mix seeds, add water with 3 kilograms of fine soil and add boron fertilizer according to the amount of 300 grams of boric acid or 500 grams of borax per mu, stir into a thin paste, then pour in radish seeds and some dry fine soil, rub by hand to make the soil containing boron fertilizer adhere to the surface of radish seeds to make seed coats, and then sow seeds when the seeds and seeds can be separated.

In the boron deficient field, from the appearance of 2 true leaves of radish to 15 days before harvest, the foliar fertilizer was sprayed with 80 100 grams of boric acid or 120 grams of 150 grams of borax to 50 kilograms of water every mu, and sprayed every 15 days and 20 days.

Whether boron fertilizer is used as base fertilizer, seed fertilizer or foliar topdressing, the soil water content in the field should be 60-80%, and soil drought will affect the boron absorption of radish. In case of continuous rainy or rainy days, water should be drained in time, especially in the seedling stage, the field should not accumulate water. Boron fertilizer has aftereffect. When applied in one season, the fertilizer effect can last for 2-4 years, and it does not need to be applied year after year.
