摘　　要：以良玉99、利民33和农华101为试验材料,在松嫩平原典型半干旱地区滴灌条件下,比较分析了覆盖地膜与不覆盖地膜的玉米产量及干物质积累特性,结果表明,滴灌玉米覆膜与不覆膜相比较,其籽粒产量显著增加,穗部性状穗长、行粒数和百粒质量显著增加,秃尖长度显著降低。植株干物质积累量覆膜比不覆膜显著增加;吐丝以后,地上部干物质积累比例和单株光合生产量覆膜比不覆膜的显著增加。Taking maize hybrid Limin33,Liangyu99 and Nonghua101as experimental materials,under the drip irrigation in typical semi-arid area of Songnen Plain,the grain yield and dry matter accumulation characteristics of maize under the plastic film and no mulching were comparatively analyzed,and the results showed that the grain yield under plastic film mulching maize was higher than that under no mulching maize,respectively.Compared with the no mulching maize,ear length,Kernels per row and 100-grain weight under plastic film mulching maize increased significantly,and bald length decreased significantly.The dry matter accumulation of maize plant increased significantly under plastic film mulching condition.After silking,compared with the no mulching maize,the dry matter accumulation ratio under plastic film mulching maize increased significantly.
