摘要:

合理使用化控剂是实现玉米产量提升的重要措施之一。本研究以高蛋白玉米品种浚单678为试验材料,研究不同叶龄期喷施不同浓度玉黄金对其植株生长性状和产量的影响。结果表明,喷施玉黄金后,浚单678株高和穗位高降低,两年平均降幅分别为7.7%~14.8%和18.1%~18.6%;相对叶绿素含量在9叶期中浓度处理下增幅最大,达5.5%;茎秆穿刺强度各处理均有提升,且处理时期越早,提升潜力越大;气生根数量在高浓度处理下增加最为显著;中浓度处理平均增产效果最佳,而11叶期高浓度处理则表现为减产。

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.

Key words: chemical control agent, maize, regulatory effect, yield
