摘　　要：以生态系统的自控能力和樟子松枯梢病流行规律为依据 ,提出了防治樟子松枯梢病的主要途径 :营造混交林 ,及时进行抚育伐和透光伐 ,是防治该病发生的根本措施 ;应用 0 14 7抗生细菌 ,含菌量 10 8个 /mL抑菌效果达82 .1% ,林间防治效果达 5 4 .1% ,该抗生细菌可以定居在樟子松针叶上 ,成为针叶叶围微生物群落 ,起到抑制病菌的作用 ;在 6月病菌孢子飞散前 ,对苗圃和重病林分喷 75 %百菌清 10 0 0×液、6 5 %敌克松 10 0 0×液、70 %甲基托布津 10 0 0×液、6 5 %代森锌 5 0 0×液 ,其防治效果分别达到 90 %以上和 70 %以上。On the basis of the automatic control ability of ecological system and the epidemiology of shoot blight of Pinus sylvestris var. mongolica, the main approaches for controlling this disease were put forward. Planting mixed forest with tending felling or cutting for pervious to light in proper time is the basic measure for preventing the disease. Using 0147 antibiotic germ with the concentration of 108 germs per milliliter to contro this disease, the rate of restrained germs was 82.1 percent and the controlling effect reached 54.1 percent. This antibiotic germ that could settle in the coniferous leaves of Pinus sylvestris var. mongolica and become microbial community around coniferous leaves, has the restraining effect on germs. Before spore dispersing in June, if nursery and forests were sprayed with 75 percent chlorothalonil 1 000×, 65 percent fenaminosulf 1 000×, 70 percent thiophanate 1 000×, 65 percent zineb 500×, the control effects could reach 90 percent and 70 percent, respectively.
