Method for preparing multi-element long-acting insecticide and fertilizer mixture capable of preventing and controlling underground pest insects of crops

Abstract

The invention discloses a method for preparing a multi-element long-acting insecticide and fertilizer mixture capable of preventing and controlling underground pest insects of crops. The multi-element long-acting insecticide and fertilizer mixture is mainly prepared by evenly mixing an inorganic fertilizer, an organic fertilizer, hydrated lime, magnesium chloride and / or magnesium oxide, ammonium sulfate, water-soluble silicate, zinc sulfate, borax and / or a boric acid, ammonium molybdate, an insecticidal plant extract, a packing and a plant regulator. The insecticidal plant extract is prepared from castor, tripterygium wilfordii, derris roots, bitter ginsengs, szechwan Chinaberry fruits, ageratum conyzoides, Chinese prickly ash powder and citrus peels, and extracting liquid prepared by adopting an ultrasonic extraction process undergoes concentration, drying, smashing, screening and even mixing to obtain the multi-element long-acting insecticide and fertilizer mixture. The insecticide and fertilizer mixture prepared by adopting the method is comprehensive in nutrition and reasonable in proportion, can effectively prevent and control underground pest insect damage of crops and increase the crop yield and can also effectively ensure ecological balance of farmland and prevent the problems of soil hardening, loss, depletion and the like.

Description

technical field [0001] The invention belongs to the technical field of crop disease and insect pest control, and in particular relates to a method for preparing multivariate and long-acting medicinal fertilizers 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...

Problems solved by technology

[0008] However, due to long-term single application, the resistance of underground pests has increased, and the soil environment has also been polluted. Problems such as soil compaction, loss, and barrenness have seriously affected the quality and safety of crops, and also endangered human health.
