After the apricot has been picked, the management cannot be loosened.
In many places, after apricot fruit is picked, farmers think that apricot management is over, neither fertilizing nor pest control or pruning, resulting in soil hardening, insufficient fertility and weak tree power, resulting in insufficient nutritional growth, insufficient storage nutrients, insufficient nutrients for flower bud differentiation and development, increased the number of degraded flowers, and serious pistil abortion. The fruit setting rate in the coming year is very low or unstable at all, and the yield and quality are better than each other year after year.
