Garlic extract based insect-resistant mulching film and preparation method thereof

Abstract

The invention provides a garlic extract-based insect-resistant mulching film and a preparation method thereof. The mulching film is sequentially provided with a surface film layer and an insect-resistant layer from top to bottom. The insect-resistant layer is prepared from a garlic extract, hydroxypropyl acrylate, styrene, chlorosulfonated polyethylene and a polyvinyl alcohol copolymer. The prepared mulching film can effectively improve the effect of the pakchoi on resisting damage of plutella xylostella, no obvious water drops are formed on the surface, facing the soil, of the mulching film, the light transmittance is good, the high soil temperature can be maintained, and agricultural production is facilitated.

Description

A kind of garlic extract-based anti-insect plastic film and preparation method thereof Technical field: The invention belongs to the technical field of agricultural plastic film, particularly relate to a kind of garlic extract-based anti-insect plastic film. Background technique: In modern agricultural production, in order to make the land have a greater crop yield, mulch material has become indispensable. production tool. The main reason why mulch can improve crop yield is that it increases soil temperature and humidity, reducing Effects of cold and dry weather on crop growth and development. There are many types of mulch, of which light-transmitting mulch is the main variety. The light-transmitting plastic film can increase the ground temperature faster, which is very conducive to soil warming and moisture preservation. It is suitable for spring, autumn and winter when the temperature is relatively cold. season. It should be noted that spring and autumn are also...

Problems solved by technology

This traditional plastic mulch has a single function. If pests and diseases occur in the farmland soil, holes need to be made on this traditional plastic film (sometimes the whole piece of the mulch needs to be lifted), and then applied to prevent harmful bacteria or bacteria in the soil. Pesticides for pest growth, etc.

However, the plastic film after the hole is difficult to hinder the outward diffusion of moisture and heat in the soil, which seriously weakens the water retention and heat preservation effect of the plastic film on the soil, which is not good for increasing agricultural production and income.
