刺槐多年卧孔菌是刺槐心材腐朽的主要致病原因,主要要危害30a生以上的刺槐,造成心材白色腐朽,损害木材的质量,导致受害树木枯死或风折后死亡。本文研究了本溪郊区人工刺槐纯林,对其用样方法划分成样地,每隔5d对其进行观察,严重的时候每隔2d观察1次,统计发病植株数量与判定病情等级。此次调查对刺槐林腐朽的原因及规律进行了总结,通过此次调查,可以拟定病害发生发展和流行的规律,是以后防治措施的理论依据。
Robinia pseudoacacia perennial fungus locust heartwood is the decay of the main cause of decay, mainly to endanger the 30a or more black locust, causing heartwood white decay, damage to the quality of the wood, leading to the victim trees dead or wind-fold death. In this paper, Benxi suburb of artificial pure locust forest, its sample method is divided into plots, observed every 5d, in severe cases observed once every 2d, count the number of pathogens and determine the severity of the disease. The survey summarized the causes and laws of decay of Robinia pseudoacacia forest, and through this investigation, we can draw up the law of development, development and prevalence of diseases, which is the theoretical basis for future prevention and control measures.
