Fertilizing leeks Within the first five days and the last five days of the beginning of each year, we can guarantee the current growth demand of leeks and the future nutrition accumulation. Fertilization should master the principle of “three combinationsâ€, that is, combination of quick-effect fertilizer and slow-effect fertilizer, combination of a large number of elemental fertilizers and trace element fertilizers, and a combination of organic and inorganic fertilizers to spray new high-fat lipid membranes to greatly increase the effective composition ratio of fertilizers. . China Agricultural Technology Network now introduces you as follows for your reference.
Select the sunny afternoon, the first stroke once again, every mu of fertilizer will be 40 kg, 3.5 kg of ferrous sulfate, borax 1.5 kg, 2.5 kg of zinc sulfate, 2.5 kg of manganese sulfate, 500 to 750 kg of bean cake mixed uniformly, with 1000 times The phoxim aqueous solution of the phoxim even sprayed the mixed fertilizer thoroughly, and after spreading it evenly, use a half-meter long 5-toothed rake to extend into the bottom of the leechee and scoop along the ridge. Try not to expose the organic fertilizer to the surface. , otherwise it loses the meaning of fertilization. Finally, plunging the water once again, and spraying phoxim or pyrethroid pesticides on the whole leaf to prevent the fly from laying eggs, and pouring the second water every 5 to 7 days. Note that the new leeks planted in that year should be 2-3 cm before the eucalyptus leaves have been cross-sealed and fertilized evenly after a uniform fertilization and watering.
After the second water is poured, it should be topdressed once every 7 to 10 days, with about 40 kg of compound fertilizer as the main ingredient. When it is cold, it will stop the water and grow long enough to allow the leeks to accumulate nutrients for this winter and next spring. Growth needs.
This fertilization can make the leeks accumulate more abundant nutrients, no shortage of fertilizer during the winter and spring growth, better growth, and ensure production. You must seize the five days before and after the beginning of autumn.
