不同灌溉方式下化控对玉米抗倒伏能力及籽粒产量的影响
Effect of Chemical Control on Maize Lodging Resistance Capability and Grain Yield under Different Irrigation Methods
摘要
Abstract
To study the effect of chemical control technology on lodging resistance and grain yield of spring maize,the agronomic traits,stem mechanical characteristics and grain yield of maize were investigated at the 6-leaf stage of maize under shallow buried drip irrigation and mulched drip irrigation,with the spraying of the chemical control agent Jade Gold(Aminoethyl ester ethephon)as the chemical control treatment(R1),and the spraying of an equal amount of fresh water as the control(R0).The results showed that maize plant height and ear height were higher under mulched drip irrigation than shallow buried drip irrigation.In terms of plant height,ear height and ear position coefficient,R1 was significantly lower than R0 under both irrigation methods.Stem thickness from the sec-ond to the fifth node was significantly higher R1 than R0,and in the sixth node,R1 was significantly higher than R0 under mulched drip irrigation,and the difference between treatments in the seventh node was not significant.The intersegmental length from the second to the seventh nodes showed that R1 was significantly lower than R0,which was especially obvious in the third and fourth node.Stem crushing strength and puncture strength showed that R1 was significantly higher than R0,and the performance of mulched drip irrigation was more obvious among the irrigation methods.Maize grain yield among drip irrigation methods showed that shallow buried drip irrigation was higher than mulched drip irrigation,and the difference between R1 and R0 was not significant under the same irrigation method.The chemical control treatment at the 6-leaf stage of maize improved the ability of stem lodging resistance and effectively reduced the risk of lodging caused by premature senescence in the late stage of maize un-der mulched drip irrigation,which is a key technical link in the cultivation of maize with dense planting and high-yield cultivation in the shallow buried drip irrigation and the mulched drip irrigation.关键词
