Abstract

The invention discloses a modified corn husk-reinforced polyethylene mulch film, belonging to the field of new material technology. The polyethylene mulch film comprises a compound of corn husk nano-filaments and submicron inorganic powder. The polyethylene mulch film prepared in the invention has excellent degradability and can perform degradation under the dual functions of edaphon and enzymes.

Description

technical field [0001] The invention belongs to the technical field of new materials, and in particular relates to a modified corn husk reinforced polyethylene film. Background technique [0002] Mulch film is the ground covering film, usually transparent or black PE film, and there are also green and silver films, which are used for ground covering to increase soil temperature, maintain soil moisture, maintain soil structure, prevent pests from invading crops and diseases caused by certain microorganisms, etc. , the function of promoting plant growth. [0003] The mulch looks like a thin layer, but it is quite effective. It can not only improve ground temperature, water, soil, fertilizer and fertilizer efficiency, but also has many functions such as weed control, pest control, drought and waterlogging resistance, salt suppression and seedling protection, improvement of light and heat conditions near the ground, and sanitation and cleaning of products. For those seedlings ...
