玉黄金化控对高蛋白玉米品种浚单678植株性状的调控效应
Regulatory effects of Yuhuangjin chemical control on plant traits of high-protein maize variety Xundan 678
摘要
Abstract
Rational use of chemical control agents is one of the key measures to increase maize yield per unit area.Using the high-protein maize variety Xundan 678 as the test material,this study investigated the effects of applying different concentrations of Yuhuangjin at different leaf stages on plant growth traits and yield.The results showed that after the application of Yuhuangjin,plant height and ear height of Xundan 678 decreased,with two-year average reductions of 7.7％-14.8％and 18.1％-18.6％,respectively.Relative chlorophyll content showed the greatest increase(5.5％)under the medium concentration treatment at the 9-leaf stage.Stem puncture strength was improved under all treatments,and the earlier the treatment stage,the greater the potential for enhancement.The number of adventitious roots increased most significantly under high concentration treatment.The medium concentration treatment achieved the highest average yield increase,while the high concentration treatment at the 11-leaf stage resulted in yield reduction.关键词
