为明确云芝葡聚糖对小麦黄矮病的预防和治疗效果,初步探讨其作用机制,西北农林科技大学植物保护学院研究人员通过室内盆栽及大田试验测定了其对小麦黄矮病的防治效果,并测定了不同浓度处理下小麦防御酶系活性的动态变化。结果表明,室内盆栽试验中云芝葡聚糖对小麦黄矮病具有较好的预防和治疗效果,其中以云芝葡聚糖100、300倍液的预防效果最为理想,防效 In order to clarify the preventive and therapeutic effects of Yunzhi dextran on wheat yellow dwarf disease and to explore its mechanism, the researchers at Plant Protection College of Northwest A & F University determined its control effect on wheat yellow dwarf disease by pot experiment and field experiment , And the dynamic changes of defense enzyme activities in wheat at different concentrations were determined. The results showed that Yunzhi dextran had good preventive and therapeutic effects on wheat yellow dwarf virus in laboratory pot experiments, of which 100 and 300 times of Yunzhi dextran had the best preventive effect and the control effect
