摘　　要：针对河北地区普遍出现的松树落枝病,将病枝进行病原分离后让其生长得到病原菌,通过采用木霉菌、化学药剂、银杏枝叶内含物与菌丝接种,测定其对菌丝生长的影响。木霉菌对菌丝生长的抑制作用很强,可抑制病原菌丝的生长,并且能穿透病原菌丝,使其萎缩,从根本上阻止了松树落枝病的发生;用化学药剂多菌灵、杜邦易保、瑞毒霉—锰锌、防病1号、防病2号、可杀得6种药剂,分别用200倍、400倍、800倍不同浓度单独与混合应用,对松树落枝病进行室内药效测定。结果表明:800倍可杀得抑制菌丝生长的能力最强,200倍、400倍、800倍多菌灵,200倍、400倍可杀得,400倍、800倍杜邦易保,200倍、400倍防病1号也有一定的杀菌能力;将药剂混合使用时,混合药剂抑制菌丝生长能力普遍增强,400倍可杀得和400倍多菌灵混合,400倍可杀得和400倍防病2号混合抑制效果异常显著;银杏枝叶内含物对菌丝有明显的抑制作用。Pine that area appear generally fall pieces of disease to pathogens after separating disease piece, through adopt wooden thing and hypha inoculate, to determine its influence of growing Hebei, carry on etiology let their growth have to go to mould, chemical drug, ginkgo brancli and leaf implicit to hypha. The inhibition that the wooden mould grows to the hypha is very strong, can suppress the growth of the pathogenic hypha, and can pierce through the pathogenic hypha,make it shrink,has prevented the pine from leaving the emergence of a disease fundamentally; Large fungus clever, Du Pont is apt to protect,auspicious and poisonous and mould with chemical drug-Manganese zinc,prevent disease 1 ,prevent disease 2, can kill 6 drug, separately with 200,400,800 different densities alone with is it fall to pine pieces of disease carry on room examine to mix,carry on the biological control. While the medicine is prevented and cured,800 times can be killed so that the ability of suppressing the hypha to grow is strongest,200 times,400 times,the clever in fungus in 800 and a half time of,can kill 200 times,400 times,400 times,800 times of Du Pont the easy to be protect,200 times,400 times have certain sterilization ability to prevent disease too on the lst; Is it when using,mix drug drug suppress hypha grow ability to be generally very much better to mix,400 times can kill and more than 400 fungus not clever to mix,can kill and prevent disease not mixing not it suppresses that result is getting more remarkable unusuallying until one 400 times; The implicit thing of branch and leaf of ginkgo has obvious inhibition on the hypha.
