Embodiment 1

[0025] A method for preparing a fertilizer having the effect of preventing and controlling underground pests of crops, comprising the following steps:

[0026] (1) Weigh the plant raw materials according to the following parts by weight: 4 parts of castor, 10 parts of Tripterygium wilfordii, 7 parts of deer vine root, 2 parts of sophora flavescens, 6 parts of toosendan, 4 parts of ageratum, 1 part of pepper powder, 5 parts of citrus peels were crushed, passed through a 50-mesh sieve, and mixed uniformly to obtain a plant raw material mixture; adding water 10 times the total weight of the plant material mixture, decocted at 70°C for 4.5 hours, filtered to remove the filter residue, and obtained water extraction liquid; the water extract is concentrated under reduced pressure into a paste, dried, pulverized, passed through an 80-mesh sieve, and mixed to obtain an insecticidal plant extract;

[0027] (2) Weigh the fertilizer components according to the following parts by weight: ...

Embodiment 2

[0029] A method for preparing a fertilizer having the effect of preventing and controlling underground pests of crops, comprising the following steps:

[0030] (1) Weigh the plant raw materials according to the following parts by weight: 10 parts of castor, 7 parts of Tripterygium wilfordii, 4 parts of deer vine root, 4 parts of sophora flavescens, 2 parts of toosendan, 6 parts of ageratum, 5 parts of pepper powder, 1 part of citrus peel, crushed, passed through a 40-mesh sieve, and mixed to obtain a plant material mixture; add water 12 times the total weight of the plant material mixture, decoct at 80°C for 3 hours, filter to remove the filter residue, and obtain a water extract Concentrating the water extract into a paste under reduced pressure, drying, pulverizing, passing through a 100-mesh sieve, and mixing to obtain the insecticidal plant extract;

Abstract

The invention discloses a method of preparing fertilizer with the effects of prevention and control of underground pests of crops. The fertilizer is mainly prepared by mixing inorganic fertilizer, organic fertilizer, an insecticidal plant extract, stuffing and a plant modifier to be uniform. The insecticidal plant extract is prepared by making castor, tripterygium wilfordii, derris roots, radix sophorae flavescentis, szechwan chinaberry fruits, ageratum conyzoides, seed powder of Chinese prickly ash and citrus peels into extracting solution through the water extraction process, and then conducting concentration, drying, crushing, sieving and uniform mixing. According to the method, by adding plant source extracts with high capability in resisting diseases and pests to the fertilizer, hazards caused by underground pests of crops can be effectively prevented and controlled; base fertilizer and insecticidal components are mixed in use to achieve the dual effects of both fertilizer and pesticide; meanwhile, soil can be improved, the ability of the soil in retaining water and fertilizer is enhanced, and the soil ecological environment is protected; the adopted raw materials come from wide sources and are low in price; moreover, the preparation process is simple, and 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 method for preparing fertilizer with the effect 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 o...
