由中国林科院林研所承担的“六五”攻关项目“以病原微生物为主的马尾松毛虫综合防治研究”和“日本赤松毛虫质型多角体病毒的引进与利用研究”,巳于1987年11月3—5日,在林业部科技司主持下,通过了鉴定。这两项研究主要在浙江省安吉县龙山林场进行。课题成果的主要特点是根据害虫综合管理的原则和试验林区的情况,结合历年松毛虫发生情况,对松休类型进行科学的划分。重点抓了松毛虫常发类型区的现有林改造,补植和封山面积占总面积的47.9％,从根本上改善了松林的生态环境。在此基础上,严格控制使用化学农药限
The Research Project on Integrated Prevention and Treatment of Deinococcus (Dendrolimus punctatus Walker) Mainly Contained by Pathogenic Microorganisms and Introduction and Utilization of Japanese Dendrolimus punctatus Polyhedrosis Virus, undertaken by Forest Research Institute of China Academy of Forestry November 3-5 years, under the auspices of the Ministry of Forestry Science and Technology, passed the appraisal. The two studies are mainly carried out in Longshan Forest Farm, Anji County, Zhejiang Province. The main characteristics of the project achievements are based on the principle of integrated pest management and the experimental forest area, combined with the occurrence of pine caterpillars over the years, the type of relaxation to conduct a scientific division. Focus on the existing types of pine caterpillars in the transformation of the existing forest, replanting and closure of the total area of 47.9% of the total area, fundamentally improved pine ecological environment. On this basis, strictly control the use of chemical pesticides limit
