摘　　要：为验证不同化控剂对小麦后期倒伏的预防效果,在冬小麦起身期选用不同的化控剂进行化控处理试验。结果表明,喷施化控剂可以缩短基部第一、第二节间长度,降低小麦株高,增加小麦穗长,缩短穗下节间长度,未出现倒伏情况;药剂处理下穗粒数增加、千粒质量降低,产量差异不显著,其中喷施质量浓度为250 g/L的抗倒酯30 mL/667 m^(2)产量最高,较对照增产10%,其次为质量分数为5%的烯效唑50 g/667 m^(2)、质量分数为20%的矮壮·甲哌嗡30 mL/667 m^(2)、质量分数为20%的多唑·甲哌嗡50 mL/667 m^(2)。综合分析,小麦起身期,首选喷施质量浓度为250 g/L的抗倒酯30 mL/667 m^(2),其次为质量分数为5%的烯效唑50 g/667 m^(2)和质量分数为20%的矮壮·甲哌嗡30 mL/667 m^(2),有较好的化控效果。In order to verify the effect of different chemical control agents on late lodging of wheat,different chemical control agents were selected to carry out chemical control treatment tests during the rise period of winter wheat.The results showed that spraying chemical control agent could shorten the length of the first and second internode of the base,reduce wheat plant height,increase wheat ear length,shorten the length of the subear internode,and no lodging occurred.The number of grains per panicle increased,the mass of thousand grains decreased,and the yield difference was not significant.According to the comprehensive analysis,the first choice was to spray 30 mL/667 m^(2) with a mass concentration of 250 g/L,followed by 50 g/667 m^(2) with a mass fraction of 5%enlobu‐lozole and 30 mL/667 m^(2) with a mass fraction of 20%.The chemical control effect was better.
