大豆孢囊线虫病是东北三省重要病害,近年来发病较重。嫩江地区历史上大豆种植面积最多为461万多亩,亩产204斤。现因此病的危害仅种植270多万亩,亩产只100斤左右。特别是本地区南部各县发病较重。为发展大豆生产,扩大种植面积,开展大豆孢囊线虫病防治研究工作,对促进大豆生产有着重要意义。我们经过四年的研究,兹将结果报道如下。 Soybean cyst nematode disease is an important disease in the three northeastern provinces in recent years, the incidence of serious. Nengjiang soybean planting area in the history of up to 461 million mu, 204 kg per mu. Now the disease is only harmed by planting more than 270 million mu, only about 100 kg per mu. In particular, the incidence of southern counties in the region heavier. In order to develop soybean production, expand planting area and carry out research on the prevention and control of soybean cyst nematode disease, it is of great significance to promote soybean production. After four years of research, we report the results as follows.
