摘要:
为了探明乙烯利、矮壮素、芸苔素内酯、胺鲜酯·乙烯利4种植物生长调节剂对玉米抗倒伏性以及产量性状的影响，本试验以玉米品种济单7号为材料。采用单因素随机区组试验设计。共设5个处理，在玉米9叶期分别喷施乙烯利、矮壮素、芸苔素内酯、胺鲜酯·乙烯利、清水，其中喷施清水为对照。结果表明，乙烯利、芸苔素内酯、胺鲜酯·乙烯利处理的株高相比清水对照显著降低；乙烯利处理的茎秆最粗，与其他3种生长调节剂处理及清水对照差异显著；4种生长调节剂处理的穗位高相比清水对照显著降低；4种生长调节剂处理均能提高玉米产量。其中，乙烯利处理的玉米产量最高。综合分析，乙烯利处理的玉米抗倒伏性较好，产量最高，与清水对照相比增产15.31%。
Abstract:
In order to investigate the effects of four plant growth regulators, ethephon, chlormequat, brassinolide and diethyl aminoethyl hexanoate·ethephon, on lodging resistance and yield traits of maize, maize variety Jidan 7 was used as the material in this experiment. A single factor randomized block design was used. A total of five treatments were set up, and ethephon, chlormequat, brassinolide, diethyl aminoethyl hexanoate·ethephon and water were sprayed at 9-leaf stage of maize. Water was used as the control. The results showed that the plant height under the three treatments of ethephon, brassinolide and diethyl aminoethyl hexanoate·ethephon was significantly lower than that under the control. The stem under ethephon treatment was the thickest, which was significantly different from that under other three growth regulator treatments and control. The ear height of maize treated with the four growth regulators was significantly lower than that treated with the water. All the four growth regulators could improve the yield of maize, and the yield of maize treated with ethephon was the highest. Comprehensive analysis showed that the lodging resistance of maize under ethephon treatment was better, and the yield was the highest, which increased by 15.31% compared with the control.
