Preparation method of special fertilizer for controlling soil insects for cherry trees

Abstract

The invention relates to a preparation method of a special fertilizer for controlling soil insects for cherry trees. The preparation method comprises four steps of: preparing a raw fertilizer, preparing a nutrient fertilizer, preparing a pesticide effect fertilizer, and mixing the raw fertilizer, the nutrient fertilizer and the pesticide effect fertilizer to prepare the special fertilizer for controlling the soil insects for the cherry trees. The special fertilizer for the cherry trees, prepared by adopting the preparation method provided by the invention, is capable of remarkably increasing the yield of cherries; and the cherries are excellent in quality, bright in color, good in taste and long in nature preservation time, and the fertilizer has a remarkable effect of controlling various diseases caused by nutrient deficiency symptom due to accumulation in successive years for the cherries; and the consumption of the fertilizer is low, and thus the cost can be reduced, and soil is not hardened. The special fertilizer for the cheery trees, prepared by adopting the preparation method, has the effect of controlling the soil insects, is capable of effectively controlling insects such as scarabs and sympiezomias velatus, is durable in effect of controlling the soil insects by combining an insecticide composition with a slow release object, and ensures that the cherry trees are strong and muscular for a long time.

Description

technical field

[0001] The invention belongs to the field of chemical fertilizer preparation, and mainly relates to a method for preparing special fertilizer for cherry trees for preventing and controlling underground pests. Background technique

[0002] Cherry, because of its beautiful appearance, tender and juicy, sweet and sour taste, and rich nutritional value, is deeply loved by consumers. The planting of cherries requires special attention to fertilizer efficiency and pests and diseases.

The larvae of scarabs and giant gray weevils erode the roots of cherry trees, causing the trees to lose their vitality and even life, resulting in a large reduction in cherry production. At present, chemical fertilizers are more and more widely used in agricultural production. Its use has greatly improved the output of agricultural products, but at th...
