摘要
对１０个试验点产量结果进行统计分析，结果表明：水稻地膜湿润栽培比对照增产达到极显著水平，三要素对产量贡献率依次为：有效穗＞穗实粒＞千粒重。分析了增产要素形成机理，介绍了该项技术的要点。
Rice yield of 10 experimental locations were statistically analyzed. The results showed that the yield of wet cultivation with film mulching was significantly higher than that of check(CK). The yield contribution rate of three key factors was respectively:effective panicle number>grain number per panicle>grain weight. The yield increase mechanism was discussed and the key techniques of wet cultivation with film mulching was introduced.
