由中国林科院林研所等单位承担的“七五”国家科技攻关项目“菌根在林业上的应用”及“菌根菌剂的制备”,于1991年2月1日通过了鉴定。受林业部科技司及中国科学院生物局的委托,中国林科院主持了鉴定会。以中国真菌学会理事长余永年教授为主任委员的鉴定委员会认为:该项研究从122种外生菌根真菌中选出13株,从14株VA真菌中筛选出2株优良菌株。在此基础上研制开发了4大类8种菌根菌剂,生产总量达2000余公斤。依据全国不同的自然经济条件,培育各种菌根化苗木30万株,平均缩短育苗周期1/3
The application of “Mycorrhiza in Forestry” and “Preparation of Mycorrhizal Fungicides”, which were undertaken by the National Forestry Research Institute and other institutes under the Seventh Five-Year Plan, passed the appraisal on February 1, 1991. Commissioned by the Ministry of Science and Technology and the Chinese Academy of Sciences Biological Bureau, the Chinese Academy of Forestry presided over the appraisal. According to the appraisal committee headed by Professor Yu Yongnian, chairman of the Chinese Society of Fungi, 13 species were selected from 122 ectomycorrhizal fungi and 2 strains were screened from 14 VA fungi. On this basis, research and development of the four major categories of 8 mycorrhizal agents, the total production of more than 2,000 kg. According to the country’s different natural and economic conditions, to cultivate 300,000 strains of mycorrhized seedlings, the average shorten the breeding cycle 1/3
