Science Topdressing Wheat Wax Fertilizer

Weak seedlings planted later, poor soil fertility and lack of base fertilizer in the wheat land, wax fertilizer to be given enough, mainly fast-acting fertilizer, per acre Shi cooked pigs, cows manure about 40 tons; or ammonium bicarbonate 20-25 Kilograms, or about 10 kilograms of urea will be applied when rain and snow are applied to promote the growth of stems and the increase of tillers. In general, wheat fields lacking phosphorus and potassium deficiency show yellowing of the lower part of leaves, red tip and old leaf tip chlorosis, followed by necrosis, and weak stalks. Phosphate fertilizer and potash fertilizer should be applied to this, 25 kg of superphosphate, 5-6 kg of potash, or 100-150 kg of plant ash should be added per acre. Grass ash can absorb heat and prevent freezing. Wang Miao base fertilizer, fertilization, early sowing, long-growing wheat, to control the amount of wax fertilizer, should be less or not chase chemical fertilizers, chase to pond mud and other miscellaneous soil-based fertilizer, combined with suppression to promote strong , Control measures to promote the improvement of wheat overwintering environment. For slender pseudo-Wang seedlings with few tillers and leaves, seedlings should be thinned in time to prevent the group from becoming too large, and at the same time, deep cultivating can be carried out. Strong seedling leaves are green and yellow, and the heart is green and yellow. From afar, the young seedlings with glossy seedlings, early sowing, full-grown feet, and full-bodied feet are suitable for applying some fertilizers, mainly using soil-based miscellaneous fertilizers, and combining repression with each mu. The topdresser is responsible for about 25 urine excrement, supplementing the nutrients needed for growing the seedlings. Chinese Agricultural Editor
