摘　　要：为了筛选出能够提高灵台县冬小麦产量的植物生长调节剂,设置了吨田宝、能百旺和对照(CK)3个处理,在冬小麦生长不同时期进行喷施试验。结果显示:在小麦冬前3叶期、起身期和扬花前各喷施吨田宝和能百旺,与CK对比,两者均可有效延长灌浆期,促进分蘖成穗,增加单位面积穗数,提高产量,但能百旺增产幅度较吨田宝高5%,建议在大田中推广使用。In order to screen out the plant growth regulator which can improve the yield of winter wheat in Lingtai County,three treatments were set up,Duntianbao,Nengbaiwang and CK,and the spray test was carried out in different growth periods of winter wheat.The results showed that spraying tons of Duntianbao and Nengbaiwang at three leaf stage,rising stage and flowering stage of wheat in the first three winter months could effectively extend the filling period,promote tillers to spike,increase the number of spikes per unit area and increase the yield,but the yield of Nengbaiwang was 5% higher than that of ton Duntianbao,so it is recommended to be popularized in the field.
