Rot the roots of leeks.Too late fertilization will gradually reduce the temperature and leeks can not accumulate enough nutrients.

In order to ensure the current growth demand and future nutrient accumulation of leeks, fertilization should grasp the "three combination" principle, that is, quick effect
