据上海市农科院和浙江省农科院等单位报道,大麦黄花叶病以土壤传播,病原主要存在于土壤表层20厘米内,以禾谷类多粘菌为媒介。据此,我所于1980年冬播早熟3号大麦时,利用抗菌剂“四○二”消毒土壤,进行防病试验,经多次调查表明效果明显。 According to the Shanghai Academy of Agricultural Sciences and Zhejiang Academy of Agricultural Sciences and other units reported that barley yellow mosaic disease spread to the soil, the main pathogen exists within 20 cm of the soil surface to cereal polymyxa as a medium. Therefore, when we used winter wheat 3 in winter to sow the barley in early 1980, we used the antiseptic “4092” to sterilize the soil to carry out the disease-prevention test. After several investigations, the results were obvious.
