光降解地膜在湛江蔗区的示范与推广

Demonstration and extension of photodegradable plastics film in sugarcane region of Zhanjiang

2005—2006年在湛江蔗区进行光降解地膜的试验示范及大田应用试验。结果表明,光降解地膜能够完全代替普通地膜,不会影响甘蔗产量及糖分的提高,示范区的光降解地膜降解失重率为7.58%～16.77%、大田应用区为11.26%～29.62%。并介绍了光降解地膜在湛江蔗区示范推广的主要措施。

The effect of photodegradable plastic film for sugarcane in sugarcane region of Zhanjiang was carried out in this paper. The results showed that the photodegradable plastic film for sugarcane （PPFS） performed as good as the common plastic film （CK） , and it wouldn’t affect the improvement of yield and sucrose content of sugarcane. The weight loss of PPFS in the area of demonstration test and application test were between 7.58% ～16.77% and 11.26% ～29.62% , respectively. Finally, we introduced the main measure on the demonstration and extension of the PPFS in Zhanjiang.
