三江平原地区大豆杀菌剂减施增效试验

Experiment of Reducing Application and Increasing Efficiency of Soybean Fungicides in Sanjiang Plain Area

为缓解三江平原地区杀菌剂施用过量等问题,试验通过采取农业措施与根部病害及叶部病害防治措施相结合的方式,利用生物菌剂拌种及有机硅助剂与杀菌剂相结合的施用方法,以期最终达到杀菌剂减施增效的效果。结果表明:杀菌剂减施增效处理对大豆根腐病的防治效果为47.80%,极显著高于普通化学药剂处理;对大豆灰斑病的防治效果为55.65%,极显著高于普通化学药剂处理;杀菌剂减施增效处理对大豆的增产效果最高,增产率为15.4%,极显著高于普通化学药剂处理。试验在减少杀菌剂施用量的同时增加了大豆产量。

In order to alleviate the problem of excessive application of fungicides in Sanjiang Plain Area,through the combination of agricultural measures,root disease control measures and leaf disease control measures,biological fungicide seed mixing and organic silicon additives combined with fungicides were used to achieve the effect of reducing fungicide application and increasing efficiency.The results showed that the control effect of treatment of reducing application and increasing efficiency of soybean disease fungicides on soybean root rot was 47.80%,which was significantly higher than that of general chemical treatment.The control effect of treatment of reduce usage and increasing efficiency of soybean disease fungicides on soybean gray spot disease was 55.65%,which was significantly higher than that of general chemical treatment.The yield increase rate of treatment of reduce usage and increasing efficiency of soybean disease fungicides on soybean root rot was 47.80%,which was significantly higher than that of general chemical treatment.The experiment not only reduced the amount of fungicide application,but also increased the yield of soybean.
