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 recom-mended to be popularized in the field.
