杨树疡壳孢溃疡病,是欧洲、美洲、近东各国普遍发生的一种杨树重要病害,从30年代以来已在欧洲和北美一些国家的杨树上危害成灾。但在我国只在个别杨树品种上有零星发生的记载,故被列为重点检疫对象。近年来,该病在国内虽有扩展的趋势,但迄今尚无系统的研究报导。为了不使该病在我国杨树人工林中危害成灾,必须引起有关方面的关注。本文报导对该病的系统研究结果,供参考。
Poplar Poppy toxoplasmosis is a serious poplar disease that is common in Europe, the Americas and the Near East. It has been devastating poplar trees in Europe and North American countries since the 1930s. However, there are sporadic records of individual poplar species in our country, so it is listed as the key quarantine object. In recent years, although there is an expanding trend in the country, there is no systematic research report so far. In order to prevent the disease from catastrophic in poplar plantations in our country, we must arouse the concern of the parties concerned. This article reports the results of the systematic study of the disease for reference.
