1985～1990年作者对甘肃省陇南地区小麦条锈病秋苗菌源动态、越冬情况及其春季流行等进行了调查研究。结果表明,该地区秋苗发病重、越冬菌源多是导致春季小麦条锈病大流行的重要原因之一。海拔1600～1800m及其相邻的部份地区秋苗发病严重或较重,是发病基地或菌源基地,亦是治理的关键地区。其治理的配套关键技术包,括改制控害、抗病品种合理布局、适期晚播和粉锈宁拌种等都是行之有效的技术。其中通过改制,建立新的农业生态体系,兼与抗病品种合理布局和调节播期相结合,构成综合的生态治理工程,并不断优化,便有可能实现持久控害致富的目的。
From 1985 to 1990, the authors investigated the dynamic changes, overwintering and spring epidemics of autumn rust seedlings of wheat stripe rust in Longnan area of Gansu Province. The results showed that the autumn seedlings in the region are heavily polluted and overwintering the source of bacteria is one of the important causes of the spring wheat stripe rust pandemic. Autumn elevation of 1600 ~ 1800m above sea level and its adjacent parts is severely or severely affected. It is a base of disease or a source of bacteria, and is also a key area for treatment. The key technology package of its management, including the restructuring control, rational distribution of disease-resistant varieties, suitable late sowing and powder rust Ning seed dressing are all effective technologies. Among them, through restructuring, the establishment of a new agroecosystem, combined with the rational distribution of disease-resistant varieties and sowing season, constitute a comprehensive ecological management project, and continue to optimize, it is possible to achieve the purpose of long-term control harm to get rich.
