大豆灰斑病、病毒病是黑龙江省三江平原大豆的两大主要病害,给大豆生产造成很大损失。大豆灰斑病在一般发病年可减产5—12％,大发生年减产31％。感病籽实的脂肪、蛋白质含量均降低。大豆病毒病一般植株发病率达60％、籽实褐斑率达10—12％,重者达70％以上,严重影响大豆出口和销售价格,尤其两种病同时流行对大豆生产影响更大。目前我省已推广了一批抗灰斑病品种,但生产中尚无抗病毒病品种,更缺少灰斑、病毒兼抗品种。
Soybean gray spot disease and virus disease are the two main diseases of soybean in Sanjiang Plain of Heilongjiang Province, causing a great loss to soybean production. Soybean gray spot disease in the general incidence of annual reduction of 5-12%, the largest annual reduction of 31%. Sick seeds, fat, protein content decreased. Soybean virus disease incidence rate of 60% of the general plant, the seed brown spot rate of 10-12%, weighing more than 70%, seriously affecting the export and sale prices of soybeans, especially the simultaneous prevalence of both diseases have a greater impact on soybean production. At present, our province has popularized a batch of anti-gray-leaf spot varieties, but there is no anti-virus disease in the production, and the lack of gray spots, viruses and anti-varieties.
