摘要: 通过设置3种不同灌溉量W1(10 m^3/667m^2)、W2(20 m^3/667m^2)和W3(30 m^3/667m^2)的膜下滴灌及常规漫灌CK(50m^3/667m^2),进行了玉米膜下滴灌干物质积累量、叶面积指数、水分利用效率、土壤含水量、玉米产量的研究。结果表明,玉米膜下滴灌可以促进其生长发育,适宜的灌溉量能够提高水分利用效率,增加土壤的含水量,干物质积累量以及促进植株的光合作用,进而提高玉米产量。各处理中W3的产量较高,W2仅次之,W2处理的干物质积累量与W3无显著差异,且W2水分利用效率较高。因此,膜下滴灌玉米较为适宜的灌溉量为20 m^3/667m^2,这对膜下滴灌玉米的增产和实际生产具有重要的实践意义。

Abstract: The experiment taked the characters of corn dry mass calculation、LAI、WUE、siol moisture content and yield under three different irrigation amout of film drip irrigation as trial content,through the corn film drip irrigation under three different water W1(10 m^3/667m^2)、W2(20 m^3/667m^2)、the W3(30 m^3/667m^2) and a control group flooding CK(50 m^3/667m^2), and reveals the corn membrane under different drip irrigation water amount of corn, corn leaf area index, dry matter accumulation in water use efficiency, soil moisture content, photosynthetic efficiency and the influence of maize yield. The results showed that the corn membrane under drip irrigation can promote crop growth and development and appropriate amount of irrigation can improve water use efficiency and increase soil water content, dry matter accumulation and the promotion of corn plant photosynthesis, thus improve the corn yield. The highest yield of each processing was W3,W2 behind the W3 and the dry matter accumulation of W2 is not significantly different from W3,but W2 has the highest water use efficiency, and are the best treatment of the water, therefore, film with drip irrigation of corn growth and development of appropriate irrigation quantity is 20 m^3/667m^2 and the drip irrigation under membrane corn production and actual production had important practical significance.
