Nontoxic insect repellant for crop as well as preparation method and usage thereof

Abstract

The invention discloses a nontoxic insect repellant for a crop as well as a preparation method and usage thereof. The nontoxic insect repellant is prepared from the following components in parts by weight: 0.5 to 2 parts of vegetable fermentation broth, 0.05 to 0.5 part of vinegar and 300 parts of water, wherein the vegetable fermentation broth is prepared from an allium vegetables, a cabbage vegetables, a green vegetables, brown sugar and warm water by fermentation. The nontoxic insect repellant is nontoxic liquid through which breaks through the conventional thinking is broken and which is used for changing, changes the insect killing carried out for guaranteeing the healthy growth of the crop into insect repellency and is invented according to the different respiratory systems of an insect and a personhuman and the dietary habit of the insect, and is sprayed on the crops, and is used for enablingso that the insect are to difficultly accept a smell given off by a synergistic effect after mixed fermentation to be unwilling to approach the crops due to a smell given off by a synergistic effect after mixed fermentation; not only can the ecological equilibrium be promoted, but also multifarious vegetables are also bioorganic fertilizer needed by the growth of a plant after being fermented; the growth of the crops is promoted while a nutrient substance is are enriched, and the nontoxic insect repellant is has the advantages of simple in production process, does not need to input a device, is low in cost and is absolutely safety, and has no need of devices.

Description

technical field [0001] The invention belongs to the technical field of insect repellent for crops, and in particular relates to a non-toxic insect repellent for crops and a preparation method and use thereof. Background technique [0002] In order to ensure that the healthy growth of crops is not invaded by insects, most of the fruit and vegetable crops need to be frequently sprayed with chemical pesticides, the purpose of which is to kill the insects that affect the crops. Although with the development of scientific research, there are a small number of pesticides that have low toxicity, but the insecticidal effect is not good. In order to prevent insects from damaging and affecting the appearance of crops, the vast majority of crops are still using highly toxic pesticides in the planting process. Although they effectively ensure the complete and beautiful growth of crops, it is well known that anything Pesticides have two sides. Pesticides are also a double-edged sword. W...

Although with the development of scientific research, a small number of pesticides are already low-toxic, but the insecticidal effect is not good

In order to prevent insects from damaging and affecting the appearance of crops, the vast majority of crops are still using highly toxic pesticides in the planting process. Although they effectively ensure the complete and beautiful growth of crops, it is well known that anything Pesticides have two sides. Pesticides are also a double-edged sword. While killing pests, they not only destroy the soil environment, but also the pesticide residues on vegetables and fruits are not easy to clean. Improper handling will seriously threaten human life and health.
