摘　　要：多年多点试验示范表明 :渗水地膜覆盖玉米增产效果显著 ,主要表现为单株生产力的提高 ,在年均积温较小的地区增产幅度大。增产机理在于土壤含水量、地积温、土壤微生物。The test results in different places and in many years showed that there was a striking increase, covered by water permeability plastic film in maize yields than conventional film and than no cover. The regional tendency is that yield will increase with temperature lowering. Water permeability plastic film can modify maximum soil moisture and improve soil environment factors.
