【摘要】 通过对樟子松林分进行生物控制技术的研究可知,在中龄林进行施用菌剂、切根、人工整枝试验对促进樟子松树势的恢复、树木胸径生长、增强树势等方面等有明显作用:在胸径生长方面,3个处理与对照差异显著,其中切根5年后的樟子松林分胸径生长高于施用菌剂和人工整枝处理,年生长量达1.89cm;3个处理与对照相比,大大减少了松枯梢病发病机率,其中修枝处理防控病害的效果最好。更多还原

【Abstract】 Through the study of bio-control technology on stand,it can be seen that application of inocula,root cutting,artificial pruning testing in half-mature forest have significant role on improving tree vigor recovery & DBH growth and enhancing tree vigor of Pinus sylvestris var.mongolica:three treatments and the control have significant differences in DBH growth;among which DBH growth of Pinus sylvestris var.mongolica five years after root-cutting are higher than that applying inocula & treating with artificial purning,annual growth being 1.89 cm;using three treatments can greatly reduce the incidence probability of Sphaeropsis sapinea,compared with the control;among which the optimal effect of controlling Sphaeropsis sapinea is pruning.更多还原
