mulch film

　　Chinese researchers have bred a new cotton variety that can reduce the usage of mulch film and avoid potential pollution.

　　Mulch film can help preserve heat, inhibite weed growth and prevent pests. However, it has become the main cause of white pollution in cotton fields, seriously affecting the quality of cotton and cultivated land.

　　A research team successfully bred a cotton variety without using mulch film. The variety also features early maturity, low-temperature tolerance and saline-alkali tolerance. Its yield can reach 350 kg per mu on average.

　　中国科研人员培育出新型棉花品种，可减少地膜使用，避免潜在污染。

　　地膜能够增温保墒、抑制杂草和防病抗虫，但是现在已成为棉田白色污染的主要原因，严重影响了棉花和耕地的质量。

　　一个科研团队成功培育出无需地膜覆盖的棉花新品种。该品种具有早熟、耐低温、耐盐碱等优点，平均产量可达每亩350公斤。
