为了提高黑龙江省有效活动积温利用效率、缓解日益扩大的水田面积与有限水资源间的供需矛盾，采用稻田覆盖地膜结合湿润灌溉方法，研究了黑龙江省水稻在覆膜、节水条件下生长发育、分蘖动态和产量构成要素等方面的影响变化。结果表明：覆膜节水对于水稻的生长发育具有积极的促进作用，能够缩短生育期；增加土壤温度；叶片叶绿素含量降低缓慢；叶面积指数增加47．37％；增产10．37％。是一项效果明显、易于农民掌握操作的节水增温高产栽培技术。
為瞭提高黑龍江省有效活動積溫利用效率、緩解日益擴大的水田麵積與有限水資源間的供需矛盾，採用稻田覆蓋地膜結閤濕潤灌溉方法，研究瞭黑龍江省水稻在覆膜、節水條件下生長髮育、分蘗動態和產量構成要素等方麵的影響變化。結果錶明：覆膜節水對于水稻的生長髮育具有積極的促進作用，能夠縮短生育期；增加土壤溫度；葉片葉綠素含量降低緩慢；葉麵積指數增加47．37％；增產10．37％。是一項效果明顯、易于農民掌握操作的節水增溫高產栽培技術。

In order to increase the efficient of active accumulated temperature in Heilongjiang province, release the contradiction between paddy field area expansion and limited water resource, the effect of rice growth, tillering dynamic change and yield components were studied by the method filming and irrigation. The result showed that there was improvement function of filming to rice growth, it could shorten growth period, increase soil temperature,decrease leaf chlorophyll content slowly, increase leaf area index by 47.37% and yield by 10.37%. It was a saving water and increasing temperature high yield cultivation technique with obvious effect and easily grasped by farmers.
