苹果腐烂病是一种难治之症,1977年开展生物防治该病的研究,就是说利用对苹果腐烂病具有桔抗作用的放线菌、真菌及细菌等微生物产生具有杀菌作用的物质,防治腐烂病。在防治腐烂病的方法中,“泥卷法”有一定的疗效,这是由于涂的泥中或苹果树皮上原来就有桔抗微生物,在处理期间,它们对病原菌有某种程度的影响。为了明确疗效的实际情况,以便应用,人们对桔抗微生 Apple rot disease is a refractory disease in 1977 to carry out biological control of the disease research, that is, the use of anti-apple actinomycosis actinomycetes, fungi and bacteria and other microorganisms have a bactericidal effect of material to prevent decay disease. In the prevention and treatment of rot disease, the “mud roll method” has a certain effect, which is due to the coating of mud or apple bark originally had anti-microbial orange, during treatment, they have some degree of pathogenic bacteria Impact. In order to clarify the actual situation of efficacy, in order to apply, people anti-micro-orange
