Pay attention to the application of wax fertilizer in wheat

The weak seedlings are planted late, the soil fertility is poor, and the bottom fertilizer is insufficient. The fertilization of the fertilization should be based on quick-acting fertilizers, about 40 tons of fermented pigs and cows per mu, or 20~25 kg of ammonium bicarbonate. Or, when the urea is about 10 kg, it will be applied when it is raining and snowing to promote the growth of stems and tillering. Generally, the wheat field lacking phosphorus and potassium deficiency shows yellowing of the lower part of the leaf, redness of the tip of the leaf and chlorosis of the tip of the old leaf, followed by necrosis and weak stem. For this application of phosphate fertilizer and potash fertilizer, 25 kg of superphosphate should be applied per mu, 5-6 kg of potash, or 100-150 kg of ash. The grass ash can act as an endothermic anti-freeze.

Wangmiao base fat foot, soil fertility, early sowing, long growing wheat field, to control the amount of fertilizer, should be less chasing or not chasing fertilizer, should be based on chasing pond mud and other soil-based fertilizer, combined with suppression to take control to promote strong And control the measures promoted to improve the wintering environment of wheat. For the fake Wang Miao seedlings with small and thin leaves, the seedlings should be sparse in time to prevent the group from being too large. At the same time, deep cultivating can be carried out.

The leaves of the strong seedlings are green, and the leaves are green and yellow. From the perspective of the wheat seedlings, the seedlings are early, the bottom is fat, and the feet are strong. The fertilizer can be applied appropriately, and the soil is mixed with the fertilizer, combined with the suppression, per mu. Pursuing about 25 tons of human and animal waste, supplement the nutrients needed for the growth of wheat.
