Degradable agricultural natural insect-repelling mulching film and preparation method thereof

Abstract

The invention discloses a degradable agricultural natural insect-repelling mulching film and a preparation method thereof, wherein the degradable agricultural natural insect-repelling mulch is made of a degradable plant fiber film, and a natural repellent is applied to the degradable plant fiber film. The preparation method comprises the following steps: mixing one, two or more plant extracts of cinnamomum camphora, houttuynia cordata, turpentine, eucalyptus, wormwood and pyrethrum with capsalcin or / and garlicin to prepare the natural repellant with insect repelling effect; and soaking the degradable plant fiber film into the natural repellant or spraying the natural insect repellant to the degradable plant fiber film. The degradable agricultural natural insect repelling mulching film disclosed by the invention has good insect repelling effect when spread on the ground or suspended on a crop, so that use of pesticide can be greatly reduced, pesticide residues on the crops can be reduced, the crops can grow in an environmentally-friendly environment, and food safety is ensured from the source.

Description

technical field [0001] The invention relates to a degradable agricultural natural insect-repelling mulch film and a preparation method thereof. Background technique [0002] At present, agricultural diseases and insect pests are becoming more and more serious. Farmers use a large amount of chemical pesticides to ensure production. With the use of chemical pesticides, pest resistance is becoming more and more serious. In order to achieve better control effects, they have to increase the amount of pesticides, forming a vicious circle. It has caused serious pollution to the environment and high pesticide residues in agricultural products, seriously affecting people's health. Therefore, developing agricultural natural insect repellent products, ensuring the environmental protection of the agricultural production process, and preventing toxic chemicals from entering the food chain is a powerful guarantee for people's food safety. [0003] At present, the insect-repellent and ins...

Problems solved by technology

[0003] At present, the insect-repellent and insect-repellent products used in China are mainly used for daily hygiene, such as camphor balls, toilet water, and insect-repellent mats. There are basically no insect repellent products used in agricultural production in the agricultural materials market. Therefore, there is a serious shortage of agricultural insect repellent products in my country, and there is great room for research and development.
