杨树苗木带菌状况与溃疡病发生的关系
The Relationship between Poplar Seedlings with Bacteria and the Occurrence of Canker
摘要
Abstract
To explore the relationship between poplar seedlings with bacteria and the occurrence of canker, this paper investigated and count diseased poplars from Yangzhuang town, Yangli town, Niuquan town, Dawang town, Kouzhen, Fangxia town etc, combing with planting test indoor and field. The results showed that outbreak of poplar canker after planting in spring mainly stemmed from seedling borne bacteria, the growth status and the quantity of bacteria carried by different seedling sources were different,the incidence and harm degree of colonization were different,there were many trees were influenced around poplar nursery.The rate of carrier of poplar seedlings was high and the incidence was heavy after planting,the key to control the disease was to eliminate the pathogens around the nursery,reduce the number of seedlings, and prevent the disease in the seedling stage and before the planting.关键词
