摘要
1981~1996年作者对汉中地区小麦条锈病发生动态进行了调查研究。结果表明,该地区在品种感病情况下,条锈病发生流行频繁,危害严重。秋苗发病重或较重,并经过冬季及早春不断侵染繁殖,积累了大量菌源,是导致春季小麦条锈病流行或大流行的重要因素。秋苗发病轻重与11月份降水量多少有密切关系,为高度正相关(R=0.8662**)。
As the results indicate,disease epidemics levels in the spring is highly correlated with the local inoculum sources of wheat in the autumn.Stripe rust occurred severely of wheat in the autumn was highly positively correlated with precipitation in November(R=0 866 2 ).
