The test was carried out in the coastal saline-alkali land with a salt mass fraction of 3‰.In this study,Jiemai 19,Jimai 22 and Jingmai 188 were used as experimental varieties to study the effects of brassinolide+pyrizolethrin on wheat yield in saline-alka-li soil by applying the combination of brassinolide and pyrizolethrin once at replanting stage,booting stage and filling stage.The re-sults showed that the yield of wheat was increased by 11.2%on average,the number of grains per spike and the weight of thousand grains were increased by 5.19%and 6.17%,respectively,and the biomass and disease resistance of wheat were increased to some ex-tent.The effect of the drug on the yield of different varieties was higher than that of Jingmai 188 than that of Gemai 19,which was re-lated to the resistance and yield level of the varieties.
