摘　　要：大兴安岭林木良种基地樟子松枯死并不是单一因素造成的,而是多种生物、非生物因子综合作用的结果,属于侵染性病害和非侵染性病害之外的第三类病害,即林木的“衰退病”。从三方面找到解决办法,查清樟子松接穗年龄对母树生命周期的影响,研究樟子松疱锈病、红斑病、松针锈病、瘤锈病等多种病害病菌孢子的飞散高度,对种子园进行有针对性的施肥,通过监测,掌握施肥对母树复壮的作用并着手二代园建设,加快遗传改良步伐。The withering and death of Pinus Sylvestris Var.Mongolica in Great Khingan Range Forest Tree Breeding Bases is a comprehensive result of various biological and abiotic factors,but not a single one,which belongs to the third category of disease beyond infectious and non-infectious diseases.By three ways to find out the impact of scion age of Pinus sylvestris var.mongolica on the life cycle of the mother tree.Study the flying height of the spores of various disease pathogens such as Pinus sylvestris rust,erythema,pine needle rust,and tumor rust,and apply targeted fertilization to seed orchards.Through monitoring,understand the effect of fertilization on the rejuvenation of the mother tree and start the construction of the second generation garden to accelerate the pace of genetic improvement.
