新疆农田地膜污染现状及对策

[目的]对新疆农田地膜残留量进行调查分析,以期为新疆地膜污染治理提供数据支撑.[方法]采取抽样方式,五点梅花形法.[结果]地膜的大范围应用, 对农业节水、增产、增效起着重要作用,新疆地膜的使用,已经有几十年的历史,地膜在农业中的应用大大提高了作物产量,增加了农民的经济收益,但同时随着地膜覆盖技术的普及,残留的农田地膜也带来了一系列的负面影响.[结论]农田地膜逐年的残留积累致使土壤耕作层对水分的吸湿性降低,渗透量减少,孔隙度下降,影响了作物正常的生长发育,特别对作物的前期生长影响较为严重,从而导致作物减产.

Present Conditions and Control Measures of Plastic Film Residue in Agricultural Fields in Xinjiang

[Objective and Metnod]The present study investigated the plastic film residue in farmland of Xinjiang to provide a basis for controlling the pollution of plastic film in Xinjiang.The method of spot check,quincunx were employed to differentiate the pratical damage of plastic film.[Result]Application of mulching plastic film in great range played an important role in water-saving,production increase and production efficiency of agriculture and also the residue of mulching plastic film in the field has already become a negative factor that affected agricultural environment,which destroyed soil structure and harmed growth of crop.[Conclusion]Based on results of domestic study on this issue,the authors advanced the techniques of preventing and controlling measures for residue of mulching plastic film.
