摘　　要：近年来节节麦对小麦生产的危害呈上升趋势,而能有效防治节节麦的农药只有世玛,但其使用条件苛刻,容易对小麦产生药害。本文就其产生药害后的缓解措施进行了研究,结果显示,出现药害后,叶面喷施碧护4g/667m^2和磷酸二氢钾200g/667m^2,25d后幼苗黄化消退矮化减轻,并且有多条新生根系。表明缓解药害效果好。In recent years,the harm of the Aegilops tauschii in wheat production is on the rise,SigMa is the only herbicide which can effectively control Aegilops tauschii in the wheat field.However,the,rigid conditions of using,it is easy to produce harm to wheat.In this paper,the mitigation measures had been studied after occurrence of herbicide injury,the results showed that the yellow leaves and dwarfing were all reduce,and it’s growing many new roots,when spraying leaves surface with 4 g/667 m2 BiHu,and KH2PO4200 g/667 m2 after 25 days.The results suggested that the method of spraying on leaves was the better effect for mitigation of herbicide injury.
