| 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、表土肥力等土壤微生态几方面均有改善.

| Abstract: | 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. |
