Abstract

The invention discloses fertilizer capable of controlling underground crop pests. The fertilizer is prepared from the following ingredients: inorganic fertilizer, organic fertilizer, a pesticidal plant extract, a filler and a plant growth regulator, wherein the pesticidal plant extract comprises the following plant materials: castor, tripterygium wilfordii, derris root, kuh-seng, Szechwan Chinaberry fruit, ageratum conyzoides, zanthoxylum powder and orange peel. A preparation method for the pesticidal plant extract comprises the following steps: performing a water extraction/alcohol extraction/ultrasonic extraction process to obtain an extraction liquid, and then performing concentration, drying, crushing, screening and uniform mixing to prepare the pesticidal plant extract. As the pesticidal plant extract of which the disease and pest resisting capability is strong is added into the fertilizer, the fertilizer can effectively prevent damage of the underground crop pests; base fertilizer and the pesticidal ingredient are mixed for use, so that the double effects of both fertilizer and pesticide are achieved; meanwhile, the fertilizer provided by the invention can improve soil, improve the water and fertilizer retention capability of soil, and protect the ecological environment of soil; the adopted raw materials are wide in source and low in price, so that the preparation cost of the fertilizer is reduced to a certain extent.

Description

technical field [0001] The invention belongs to the technical field of crop disease and insect pest control, and in particular relates to a fertilizer for 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 affect the industrial developmen...
