The research and application of liquid membrane

Abstract

By the serious soil “white pollution”, the research and application of liquid membrane for the prevention of soil pollution caused by plastic mulch is of great significance. The article reviews the development process of the liquid membrane materials, summarizes the application effects of different liquid membranes on soil improvement and water use, points out limitations of liquid membrane and the future development trend. With natural biodegradable materials (especially the industrial and agricultural waste) as raw material to develop new type of multifunctional biodegradable liquid membrane is a hotspot of current research of liquid membrane. Past research is mainly for agricultural water saving and moisture conservation, the future research should strengthen the study of soil degradation, soil and water conservation and the control of degradation rate.

Keywords:

• liquid membrane
• white pollution
• degradability
• multifunction materials
