摘要
采用田间试验方法,在小麦播种期、分蘖至起身期、拔节至抽穗期各喷施1次0.136%赤·吲乙·芸苔可湿性粉剂,并配合使用生物助剂、液体硅肥和除草剂,研究植物生长调节剂赤·吲乙·芸苔对小麦生长发育及产量的影响,旨在为小麦增产提质提供新手段。结果表明,0.136%赤·吲乙·芸苔可湿性粉剂对小麦生长发育有明显促进作用;与不施生长调节剂相比,0.136%赤·吲乙·芸苔可湿性粉剂处理后的小麦穗长、穗数、穗粒数、千粒质量分别增加了1.45%、1.44%、4.03%、5.64%,产量提高了9.65%。赤·吲乙·芸苔可湿性粉剂可以在小麦生产中推广应用。
GA·IAA·BR on the growth and yield of wheat by spraying 0.136%GA·IAA·BR wettable powder once at sowing date,tillering-rising stage and jointing-heading stage,together with the use of biological additives,liquid silicon fertilizer and herbicide,to provide a new method for increasing the production and quality of wheat.The results showed that 0.136%GA·IAA·BR WP had a significant effect on the growth and development of wheat.Compared with no growth regulator,the ear length,ear number,grains number per ear and 1000-grain quality of wheat treated with 0.136%GA·IAA·BR wettable powder increased by 1.45%,1.44%,4.03%,and 5.64%,respectively,the yield increased by 9.65%.Therefore,GA·IAA·BR can be popularized and applied in wheat production.
