摘　　要：选用灵滟、矮壮丰、爱久收、直播龙、劲丰谷德5种化控产品,研究其在小麦上的应用效果。结果表明:5种化控产品均可增加小麦产量,与空白对照相比,增产279.75~988.55 kg/hm2,增幅3.63%~12.84%,以灵滟的增产效果最佳;5种化控产品均可提高小麦第2节间抗折力,与空白对照相比,增加0.02~0.46 N,增幅1.32%~30.46%;各处理对小麦株高均有化控作用,均无倒伏发生;对小麦节间长度和茎秆粗度的影响总体表现为缩短小麦节间长度,增粗小麦茎秆粗度。生产上可根据需要,在小麦不同生育期推广适宜的化控产品。This paper selected five chemical control products(Lingyan,Aizhuangfeng,Aijiushou,Zhibolong and Jinfenggude)to study their effects on wheat.The results showed that all five chemical control products could increase wheat yield.Compared with the blank control,the yield increased by 279.75-988.55 kg/hm2,with an increase of 3.63%-12.84%.Lingyan had the best yield increase effect.All five chemical control products could improve the second internode bending resistance of wheat,compared with the blank control,the second internode bending resistance increased by 0.02-0.46 N,with an increase of 1.32%-30.46%.Each treatment had chemical control effect on wheat plant height,and no lodging occurred.The overall impact on the internode length of wheat was shortened,while the overall impact on stem coarseness was increased.Suitable chemical control products can be popularized at different growth stages of wheat according to production needs.
