大豆是我省的第三大秋粮作物,近年来种植面积逐年增加,1993年已超过110万亩。其营养价值高,并可与玉米进行套作,起到提高光热资源利用率和种地养地的作用。但随着种植面积不断扩大,大豆锈病不断发生,并呈上升趋势,成为发展大豆生产的重要限制因子,为探讨防治技术,寻找有效药剂。我们利用几种杀茵剂进行了药效试验,现将结果总结如下:
Soybean is the third largest autumn crop in our province. In recent years, the acreage has been increasing year by year. In 1993, it exceeded 1.1 million mu. Its high nutritional value, and can be intercalated with corn, played to improve the utilization of light and heat resources and the role of farming to support. However, as the planting area continues to expand, the rust of soybean continues to occur and is on the rise, becoming an important limiting factor in the development of soybean production. In order to explore prevention and control technologies and to find effective medicaments, We use several kinds of virulent drug efficacy test, the results are summarized as follows:
