1971年,我们从襄北土壤中分离筛选出一株球孢链霉菌,编号为鄂襄菌1号。经几年的小区试验和大田示范,该菌剂对玉米大斑病与棉苗炭疽病有较好的防治效果。1976年,在全地区的9万亩玉米、1,350亩棉花上应用,也都获得较好的效果。现将鄂襄菌1号的防病效果及土法生产报道如下。 In 1971, we isolated and screened a strain of Streptomyces coelicolor from soil in North Hubei Province, and numbered E-xian 1. After several years of plot test and Daejeon demonstration, the fungicide has a good control effect on corn leaf spot and cotton seedling anthracnose. In 1976, 90,000 hectares of corn and 1,350 hectares of cotton were applied in the region, all of which achieved good results. Now Euxian 1 disease prevention and soil production reported as follows.
