Embodiment 1

[0027] A method for preparing a medicinal fertilizer with plant-derived insecticidal components, comprising the following steps:

[0028] (1) Plant raw materials were weighed according to the following parts by weight: 10 parts of castor, 4 parts of tripterygium wilfordii, 7 parts of deer vine root, 2 parts of sophora flavescens, 4 parts of toosendan, 5 parts of ageratum, 1 part of pepper powder, 5 parts of citrus peels were pulverized, passed through a 50-mesh sieve, and mixed uniformly to obtain a plant material mixture; adding medicinal ethanol 10 times the total weight of the plant material mixture, leaching for 3 hours, filtering to remove the filter residue, and obtaining an alcohol extract; Concentrate the alcohol extract under reduced pressure into a paste, dry, pulverize, pass through an 80-mesh sieve, and mix well to obtain the insecticidal plant extract;

[0029] (2) Weigh the medicinal fertilizer components according to the following parts by weight: inorganic fert...

Embodiment 2

[0031] A method for preparing a medicinal fertilizer with plant-derived insecticidal components, comprising the following steps:

[0032] (1) Weigh the plant raw materials according to the following parts by weight: 4 parts of castor, 7 parts of Tripterygium wilfordii, 10 parts of deer vine root, 6 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 uniformly to obtain a plant material mixture; add medicinal ethanol 12 times the total weight of the plant material mixture, extract for 4 hours, filter to remove the filter residue, and obtain an alcohol extract; Concentrate the alcohol extract under reduced pressure into a paste, dry, pulverize, pass through a 100-mesh sieve, and mix well to obtain the insecticidal plant extract;

Abstract

The invention discloses a method for preparing insecticide-fertilizer with plant source insecticide ingredients. The insecticide-fertilizer is prepared mainly by uniformly mixing inorganic fertilizer, organic fertilizer, slaked lime, magnesium chloride and/or magnesium oxide, ammonium sulfate, water-soluble silicate, zinc sulfate, borax and/or boric acid, ammonium molybdate, 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. The insecticide-fertilizer prepared with the method has rich nutrients, material matching is reasonable, damage caused by soil crop pests can be effectively controlled to increase crop yield, farmland ecological balance can be effectively guaranteed, and soil hardening, loss and infertility are prevented.

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 medicinal fertilizer with plant-derived insecticidal components. 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 in...
