摘　　要：2a对 4种小麦抗倒剂的试验表明 ,DF 5、烯效唑、壮丰安、多效唑对小麦都具有抗倒增产作用。在小麦中后期降水偏多 ,发生倒伏的情况下 ,DF 5 3 0 0 0ml/hm2 、烯效唑 480g/hm2 和多效唑 10 5 0g/hm2 都能明显增强小麦基部节间强度 ,增强抗倒能力 ,分别增产 17.6 %、6 .5 %和 2 .3%。在小麦中后期干旱 ,小麦不发生倒伏的情况下 ,烯效唑 15 0 0g/hm2 、壮丰安 15 0 0ml/hm2 增产明显 ,分别增产 7.4%和 6 .7% ,DF 5和多效唑虽然也增产 。The two year study of 4 different lodging resistance agent of DF 5,pentefezo,zhuangfengan and ppp333 in wheat indicated that all of the treatments made the yield and lodging resistance increased.The heavy rain and wind in the late stage resulted in wheat lodging and DF 5 3000 ml/hm 2,pentefezo 48g/hm 2 and ppp333 1050g/hm 2 can obviously improve the basic stem intensity and loding resisance and yield increased 17.6%,6.5% and 2.3% separatively.In the late stage,when it was dry and no lodeing,pentefezo 1 500 g/hm 2 ,zhuangfengan 1500g/hm 2ppp333 slightly increased yield.
