Embodiment Construction

[0012] The degradable agricultural natural insect-repelling mulch film of the present invention is made of degradable plant fiber film, and there is a natural insect repellant on the degradable plant fiber film, and a layer of vegetable paraffin can also be covered on this basis, and the following steps are followed for manufacture conduct:

[0013] (1) Prepare degradable plant fiber membranes and prepare one or more of the following plant extracts: camphor, Houttuynia cordata, turpentine, eucalyptus, mugwort, pyrethrum, each extract can be mixed in any proportion;

[0014] (2) Add capsaicin or allicin to the plant extract to obtain a natural insect repellent. Capsaicin or allicin accounts for 20-30% of the weight of the natural insect repellent. Capsaicin and allicin can be used in combination, but the two The sum of the weights of the two accounts for 20-30% of the weight of the natural insect repellant. For more than one plant extract, each plant extract can be mixed first...

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...
