为了验证小麦地膜覆盖技术是否适用不同气候地区。于2012－2013年在河北省曲周县中国农业大学万亩“双高”示范基地，在灌溉条件下观测了地膜覆盖对冬小麦生长发育及倒伏性能的影响。试验结果表明，地膜覆盖对小麦生长发育，尤其是前期群体数量和叶面积等有一定的促进作用，但在当季小麦生长后期雨水较多的情况下，会因使根系分布变浅、基部节间变长而增加小麦倒伏风险，抵消其增产增收的效果，据此探讨了华北灌区小麦覆膜栽培中需要注意的问题。

In order to investigate the effects of film mulching on winter wheat growth ,development and lodging properties in Southeast Hebei .We carried out at the demonstration bases of China Agricultural University on the high yield and high efficiency technology from 2012 to 2013 in Quzhou County .The results showed as follows:Al-though the film mulching have a certain role in promoting to wheat in the aspect of grain weight ,but in the cases of more rain in the growth of wheat late ,and sowing ,irrigation and other agronomic measures if done incorrectly ,it will increase the risk of wheat lodging ,reach the effect of increasing production .
