Explosive winter leeks pay attention to å•¥
Watering When the temperature falls below -5°C, the ground begins to freeze and the leek begins to enter the wintering period. At this point, you must pour the frozen water in time. In this way, underground rhizomes can be prevented from freezing damage, and spring drought can be prevented, laying a good foundation for early spring and long-term spring. Watering is too early, the ground is not frozen, the soil water disperses quickly, and the effect of storing water is poor; watering is too late, the soil is frozen, and the freezing injury is exacerbated after watering, and the roots are prone to hypoxia suffocation and death. Therefore, freezing water is most suitable when the soil is frozen overnight. The second is to re-apply wax and wax fertilizer can not only increase the temperature of cold, but also have the effect of winter Shi Chun. The wax-fertilizer is better for decomposed human excrement, and Mushi 1500-2000 kg. Thirdly, during the period of wintering, the soil between the rows should be cultivated to the root of the leeks, not only to prevent freezing, but also to loosen the soil and improve the soil permeability structure, which is beneficial to the absorption of nutrients by the root system. Usually two or three times during the entire winter. The four to cover the use of cattle, horse dung or hay covered in the leeks on the surface, can be preserved, warming, antifreeze. Each mu of cattle, horse manure 2500 kg or firewood 250 ~ 300 kg, evenly cover the leeks can be noodles.
