Fertilizing leeks in the first five days and five days after the beginning of autumn each year can ensure the current growth needs of leeks and the accumulation of nutrients in the future. Fertilization should master the "three combinations" principle, that is, the combination of quick-acting fertilizer and slow-acting fertilizer, the combination of large element fertilizer and trace element fertilizer, the combination of organic fertilizer and inorganic fertilizer, and the spraying of new high-fat film, which greatly improves the effective component rate of the fertilizer. . Choose a sunny afternoon, first hoeing, mix 40 kg of compound fertilizer, 3.5 kg of ferrous sulfate, 1.5 kg of borax, 2.5 kg of zinc sulfate, 2.5 kg of manganese sulfate, 500 to 750 kg of soybean cake, and use 1,000 times per mu of land. Sprinkle the mixed fertilizer evenly with the phoxim aqueous solution. Spread it evenly between the chives, and then use a half-meter-long 5-tooth small rake to reach under the chive rack and hoe along the ridges. Try not to expose the organic fertilizer on the ground. , Otherwise it loses the meaning of fertilization. Finally, water the large water along the ridge again, and spray phoxim or pyrethroids on the whole leaf surface to prevent flies from laying eggs, and then water a second time every 5 to 7 days. Note that the new leeks planted that year should be hoeed 2 to 3 cm before the leeks have been cross-sealed, and then hoeed and watered again after uniform fertilization. After the second watering, top dressing should be done every 7 to 10 days, with about 40 kg of compound fertilizer as the main ingredient. When the cold dew, the water is stopped to control the length, so that the leeks can accumulate nutrients for this winter and next spring. Growth needs. In this way, fertilization can make the leek accumulate richer nutrients, and there will be no shortage of fertilizer during winter and spring growth, better growth, and guaranteed yield.
