Description

Slow release device capable of remarkably improving utilization rate of chemical fertilizer

Technical Field

The invention relates to the technical field of fruit tree planting and fertilizing, in particular to a slow release device capable of remarkably improving the utilization rate of a chemical fertilizer.

Background

When fruit tree planting is carried out, in order to improve the yield of fruit trees and the quality of fruits, the fruit trees need to be fertilized so as to provide sufficient nutrition for the fruit trees. When the fruits and vegetables are fertilized, besides natural farmyard manure, a certain amount of proportioned fertilizer is applied according to the requirement of fruit tree production on trace elements.

When the fruit trees are fertilized in the prior art, the fertilizing mode can be roughly divided into one-time sufficient fertilization and a small quantity of multiple sufficient fertilization, because the fruit trees slowly absorb the fertilizer along with the growth of the fruit trees, the one-time fertilization is easy to cause waste, the fertilizer can be absorbed by peripheral weeds, the small quantity of multiple fertilization is relatively less in waste, but the labor capacity is obviously increased, and the utilization rate of the fertilizer is still not high.

In order to solve the above problems, we propose a slow release device that can significantly improve the utilization rate of fertilizer.
