Radish Boring Fertilizer

As basal fertilizer, when radish sowing, 300 grams of boric acid per acre or 500 grams of borax, mix in 5 ~ 10 kilograms of dry fine soil, fully mix and sifted, and then apply basal fertilizer into seed ditch or seed hole. The radish seeds can also be mixed into the dry fine soil mixed with boron fertilizer, and the mixture is thoroughly mixed and sprinkled into the seed grooves and seed holes.

For seed dressing, add 3 to 5 kg of fine soil and add 300 grams of boric acid per acre or 500 grams of borax per acre to mix the boron fertilizer into a thin paste, then pour the radish seeds and a number of dry fine soils. The soil containing the boron fertilizer is adhered to the surface of the seed to form a seed coat with a handkerchief, and the seeds can be sown after being separated from the seed.

The fertilizer is applied from outside the root, in the field of boron depletion, from 2 to 3 true leaves of the radish to 15 days before harvest, 80 to 100 grams of boric acid or 120 to 150 grams of borax for 50 to 60 kilograms of clean water per acre. , formulated as foliar fertilizer spraying in the evening of the sunny day, spray once every 15 to 20 days.

Regardless of whether boron fertilizer is used as base fertilizer, seed fertilizer or foliar fertilizer, the moisture content of field soil must be controlled at 60% to 80%. Drought in soil will affect the absorption of boron by radish. If there is continuous rain or heavy rain, it should be drained and drained in time, especially in the field during seedling period. The boron fertilizer has a post-effect. After one season of application, the fertilizer effect lasts for 2 to 4 years, so it is not necessary to apply it for consecutive years.
