Fertilizing leek can ensure the current growth demand and future nutrient accumulation of leek in the first five days and five days after the annual fall. Fertilization should master the principle of “three combinationsâ€, that is, the combination of quick-acting fertilizer and slow-acting fertilizer, combining a large amount of elemental fertilizer with trace element fertilizer, combining organic fertilizer with inorganic fertilizer and spraying new high-fat membrane to greatly improve the effective component rate of fertilizer. . China Agricultural Technology Network will introduce you to the following for your reference.
Select sunny day in the afternoon, first make a row of paddy, 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, and 500-750 kg of bean cake mixed evenly, 1000 times. The phoxim aqueous solution will evenly spray the mixed fertilizer. After spreading evenly between the mashes, use a half-meter-long 5-toothed scorpion to extend into the leeks and stalk the ridges. Try not to expose the organic fertilizer to the surface. Otherwise, the meaning of fertilization is lost. Finally, the water is poured once along the ridge, and the phoxim or pyrethroid agent is sprayed on the whole leaf surface to prevent the eggs from being flies, and the second water is poured every 5 to 7 days. Note that the new leeks planted in the same year should be raked 2 to 3 cm before the leaves are not cross-sealed, and then evenly fertilized and then watered and watered. After pouring the second water, it should be topdressed every 7 to 10 days, with a compound fertilizer of about 40 kg. When the cold dew is stopped, the water is controlled, so that the leek can accumulate nutrients for the winter and next Spring. Growth needs. This fertilization can make the leek accumulate rich nutrients, and it will not lack fertilizer when growing in winter and spring, and it will grow better and ensure the yield. You must be sure to catch the five days before and after the fall.
