Weak seedlings planted later, poor soil fertility and insufficient base fertilizer in the wheat field, the wax fertilizer should be given enough, mainly based on quick-acting fertilizers, the cooked pigs per mu, about 40 lbs of cowshed, or ammonium bicarbonate 20~25 kg. , Or will be about 10 kg of urea when it rains and snow after the topdressing to promote the growth of stems and tillers increase. In general, wheat fields lacking phosphorus and potassium deficiency exhibited 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 area, and 25 mu of superphosphate, 5 to 6 kg of potash, or 100 to 150 kg of plant ash should be added per mu. 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 to chase chemical fertilizers, to recover the mud and other land-based miscellaneous 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.
