Wheat is subjected to freezing damage during the winter, and if the sensation is appropriate, it can be fertilized on a sunny day during the winter. After returning to green, the water-controlled fertilizer is changed to fertilize water and promote the healthy growth of wheat seedlings.
The main stem of the wheat seedlings and the frozen wheat field of the big tiller are fertilized twice to promote the rapid growth of small tillers. For the first time, after the thawing in the field, the quick-acting nitrogen fertilizer was applied, and 10 kg of urea per mu was applied, and the water-deficient wheat field was poured with water. Phosphorus has the function of promoting tillering and root growth, and the phosphorus-deficient wheat field can be mixed with urea and diammonium phosphate. For the second time, in the jointing stage of wheat, combined with watering and water saving, 10 kg of urea per acre was applied. Generally, frozen wheat fields (only frozen leaves, no dead cockroaches) should be drawn early in the early spring to increase the ground temperature, promote the return of the wheat seedlings, and fertilize and water the body during the body-raising period to increase the tillering rate.
