Abstract

The invention discloses a method for preparing fertilizer capable of controlling soil crop pests. The fertilizer is prepared mainly by uniformly mixing inorganic fertilizer, organic fertilizer, pesticidal plant extract, filler and plant regulator. The pesticidal plant extract is obtained by conducting condensation, drying, smashing, screening and uniform mixing on an extracting solution prepared from castor-oil plant, thunder god vine, derris root, radix sophorae flavescentis, szechwan Chinaberry fruit, ageratum conyzoides, paprika powder and orange peel through ethanol extraction. By adding plant source extract with high disease and pest resistance to the fertilizer, damage of soil crop pests can be effectively controlled; base fertilizer and insecticide ingredients are mixed to be used, fertilizer functions and insecticide functions are realized, soil improvement is achieved, water and nutrient retention capacity of soil is improved, and the ecological environment of soil is protected; raw material sources are wide, price is low, preparing process is simple, and the preparing cost of the fertilizer is reduced to a certain degree.

Description

technical field [0001] The invention belongs to the technical field of crop disease and insect pest control, and in particular relates to a preparation method of a fertilizer capable of preventing and controlling underground pests of crops. Background technique [0002] Sugar cane, peanuts, corn, sweet potatoes and vegetables are the main crop varieties in the south, especially in Guangxi, and they are the source of income increase for farmers. However, due to the constraints of the land, the crop rotation is difficult, the continuous cropping is inevitable, and under the condition of high soil temperature and humidity, it is easy to breed underground pests. In recent years, the planting of vegetables, corn, and potatoes has been increasingly harmed by underground pests. Seriously, the white radish "flower skin" cannot be sold, and the "black heart" of sweet potatoes has halved the output. These are all caused by the damage of underground pests. Underground pests not only a...
