四川宜宾烟区地膜残留量及影响因素研究

Analysis on Membrane Residue and Influence Factors of Yibin Tobacco Area in Sichuan

[目的]调查四川宜宾烟区地膜残留量并分析其影响因素。[方法]对不同覆膜期和覆盖不同地膜类型的地膜残留情况进行调查。[结果]宜宾烟区烤烟地平均地膜残留量为6.878 kg/hm^2,地膜残留量较大,造成了一定的"白色污染",给烟区农业环境安全带来了一定的不利影响。[结论]该研究结果为宜宾烟区地膜厚度选择及地膜残留的防治提供了参考。

[Objective] The aim was to analyze membrane residue and influence factors of Yibin tobacco area in Sichuan. [Method]The residues of membrane of Yibin tobacco area in Sichuan was investigated under different film-mulching stages and different types of membrane.[Result]The average residue of membrane of Yibin tobacco area in Sichuan was 6. 878 kg/hm2,which caused certain‘white pollution＇and brought certain adverse effects on the agricultural environment safety in tobacco area. [Conclusion]The results provide reference for the selection of geomembrane thickness and prevention and treatment of geomembrane residues.
