摘要
1980～1983年在乌鲁木齐市对新疆及外地几个苜蓿品种比较试验过程中,观察到苜蓿死亡现象。经统计,外省区及外国品种死亡率高,生长势差;本地品种死亡率较低,生长良好。经1983～1986年病理学研究,证实系立枯丝核菌及镰刀菌引起的苜蓿根腐病,该病为新疆首次发现。
In our study on comparison of the alfalfa cultivars from different regions during 1980～1983. the death phenomenon of overwintering plants was observed. The result of statistics analysis showed that the deathrate of the eultivars from abroad and the other provinces of China were higher than that of local cultivars. Through phytopathological research during 1983～1986, we demonstrated that the death phenomenon was due to the root rot diseases caused by the root rot inciting fungi, Rhizoctonia solani and Fusarium sp. which were new records in Xingjiang.
