Abstract:

As a completely biodegradable agricultural mulching material, degradable liquid mulching films are considered as a type of agricultural films in accordance with the new development trend. This paper systematically summarized the types, characteristics and performance of degradable liquid mulching films, and also analyzed the representative technology and preparation mechanism of natural polymer material liquid mulching films on the basis of the grafting copolymerization mechanism. Moreover, the application status and effects of representative liquid mulching film materials at home and abroad were evaluated. Furthermore, some opinions were proposed to address difficulties in the development of current liquid mulching film materials, providing a technical support for the exploitation of new liquid mulching film materials and their performance enhancement.

Key words: liquid mulching film, degradablility, soil conditioner, research status, application prospect
