With the application of large numbers of agricultural film, the environmental problem has becomes more and more serious. 2.1The growth of crops inhibited by residual film The main composition of agricultural film materials is polymer compounds, in the natural conditions, these high polymer is difficult to decompose, if be retened long-term in the ground, it will affect soil permeability root growth of the crops, and prevent soil water migration ,leading to crop failure.

Influence of Corn Straw Fibers and Polymer Latexes on Vibration Damping Property of Cement-Based Materials Liguang Xiao, Yuanchao Li, Ruibo Li College of Material Science and Engineering, Jilin Architectural and Civil Engineering Institute, Changchun 130118, P.
The experimental results showed that the vibration damping ratio of cement- based materials with organic polymer latexes is 149.77% higher than that of pure cement-based materials, the vibration damping ratio of cement-based materials with corn straw fiber is 152.58% higher than that of pure cement-based materials, the vibration damping ratio of cement-based materials with organic polymer latexes and fibers blending is 191.08%, also higher than that of pure cement-based materials.
Introduction The cement-based materials such as concrete and cement mortar, are the largest amount of engineering materials currently used in the world.
