| Abstract: | Winter wheat varieties Weimai 8 and Taishan 23 were used to study the effects of silicon-potassium fertilizer on reducing the injury to winter wheat in the years with serious late frost.The results showed that basal dressing of silicon-potassium fertilizer could significantly reduce the late frost injury and increase the ear number per unit area,grain number per ear and 1000-grain weight.Its disaster reduction effect was significant and its role in creating the high-and stable-yielding fields was prominent. |
