example 1

[0017] Take fresh twigs, rinse the surface with water, and then dry them naturally. When the water content is lower than 15%, use a straw grinder to crush the branches into 1cm pieces, and put the obtained pieces into pieces. Put it into an extruder and extrude it into a block, then put it into a carbonization furnace, and carbonize it at a temperature of 240 ° C for 50 minutes; after the above carbonization is completed, take it out and put it into a pulverizer for crushing Standard sieve to obtain 60-mesh carbonized cloverleaf branches particles, then put the particles into a container, add a hydrochloric acid solution with a mass fraction of 15% to soak the particles, let it stand for 30 minutes in an environment with a frequency of 20MHz, and then filter and dry , to obtain modified carbonized Cedarwood branch particles; according to mass percentage, get 45 parts of modified carbonized Cedarwood branch particles, 15 parts of deer vine root, 15 parts of bean root, 20 parts o...

Abstract

The invention discloses a preparation method of a natural solid granular insecticide and belongs to the technical field of pesticide. In allusion to the problem that currently traditional insecticides are mostly chemical preparations, have high toxicity, are easy to harm safety of human and livestock and severely affect environmental health and safety, the invention provides a natural solid granular insecticide which is prepared by steps of using modified and carbonized cephalotaxus fortune branch particles as a carrier, mixing crotalaria mucronata root, maidenhair and the cephalotaxus fortune branch particles and fermenting, filtering and the like. The prepared insecticide is a natural insecticide, causes no pollution to the environment, contains no harmful substances, and is harmless to human body. Insecticidal rate of the insecticide reaches 96% and above.

Description

technical field [0001] The invention discloses a preparation method of a natural solid particle insecticide, which belongs to the technical field of pesticides. Background technique [0002] In recent years, insecticides used in food and vegetables have attracted more and more attention. Most of the domestic similar insecticides are imitating foreign products to produce highly toxic insecticides. These pesticides in the prior art have a strong and unpleasant smell, and are likely to endanger the safety of humans and animals, and seriously affect environmental sanitation and safety. [0003] Traditional pesticides are mostly chemical preparations. How to use plant sources as pesticide ingredients to reduce pollution is a problem that needs to be solved. Contents of the invention [0004] The technical problem mainly solved by the present invention: aiming at the problems that the current traditional insecticides are mostly chemical preparations, highly toxic, easily endang...
