赤霉病、根腐病是我省小麦生产的重要病害。据植保部门调查,我省小麦叶枯80%是由小麦根腐病引起的。赤霉病主要流行在合江、牡丹江等东部低湿地区。1959、1960年曾造成严重损失,近年来发病率一般在5~15%左右,严重的高达30%以上。由于赤霉病、根腐病的危害,导致小麦产量、品质和食用价值降低,是发展我省小麦生产迫切需要解决的问题。 Fusarium head blight and root rot are important diseases of wheat production in our province. According to the plant protection department survey, 80% of wheat leaf blight in our province is caused by the root rot of wheat. Fusarium head blight mainly in Hejiang, Mudanjiang and other eastern low humidity areas. 1959, 1960 caused serious losses, in recent years the incidence is generally about 5 to 15%, severe up to 30% or more. As a result of scab and root rot hazards, the yield, quality and edible value of wheat decrease, which is an urgent problem to be solved in wheat production in our province.
