Problems solved by technology

Undoubtedly, it will increase the labor cost in the process of planting crops, and will be subject to certain conditions. In addition, the traditional herbicide spraying method will cause the loss of herbicide during the spraying process and cause environmental pollution; while the existing mulch film is large Some also have the defects of poor impact resistance and poor air permeability, which affect their scope of use

Abstract

The invention relates to an agricultural mulching film with disinsection and weeding functions and a preparation method thereof, and belongs to the technical field of agricultural products. The preparation method comprises the following steps: by taking hickory nut green pericarp as a raw material, utilizing allelopathic substances and fiber components in the hickory nut green pericarp, carrying out a series of modification treatment, matching with silicon dioxide aerogel to prepare a mixed filler, doping the obtained mixed filler into a film matrix, and finally carrying out extrusion granulation, pressing and film blowing to finally prepare the agricultural mulching film with the deinsectization and weeding functions. The agricultural mulching film prepared by the invention is excellent in disinsection and weeding functions, excellent in air permeability and impact resistance and wide in application prospect.

Description

technical field [0001] The invention relates to an agricultural mulch film with the function of eliminating insects and weeds and a preparation method thereof, belonging to the technical field of agricultural products. Background technique [0002] In recent years, in order to improve the growth environment of crops and increase crop yields, ground covering mulches with high thermal insulation and moisturizing properties have been used in agricultural production. On the one hand, most of the existing plastic mulches are not naturally degradable, causing extremely serious environmental pollution. On the other hand, after the crops are cultivated using the mulching technology, a relatively high-temperature and high-humidity ecological environment is formed under the film, which is conducive to the germination of crops. growth, so it can increase crop yield and harvest, but at the same time, this high-temperature and high-humidity ecological environment is also conducive to the...
