硅钾肥在减轻冬小麦晚霜冻害及创建高产稳产田中的作用

摘要

在晚霜冻害严重发生年份,以潍麦8号和泰山23为供试品种,多点跟踪调查结果表明:基施硅钾肥能显著减轻晚霜冻害发生程度,单位面积穗数、穗粒数、千粒重皆增加,具有显著的减灾效果,在创建高产稳产田中作用突出.%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.
