南京农业大学与江苏省农科院、江苏省农林厅于1983年联合承担江苏省科委下达的“根瘤菌应用技术承包和提高共生固氮效益的研究”任务。两年多来,通过示范推广豆科作物接种根瘤菌技术,取得了显著的经济效益和社会效益。 在江苏省东海、新沂、赣榆、泰兴等十多个县,一百多个定点小区对比试验表明,花生接种根瘤菌的比未接菌的平均增产率分别为11.4％和16.8％,每亩增收花生果均在四、五十斤以上。其中泰兴县1983年花生接种根瘤菌八千七百亩,每亩平均增产51.1斤(增产率
Nanjing Agricultural University and Jiangsu Provincial Academy of Agricultural Sciences, Jiangsu Provincial Department of Agriculture and Forestry in 1983 jointly assumed the Jiangsu Provincial Science and Technology Commission issued the “Rhizobium application of technology contract and improve symbiotic nitrogen fixation benefit” task. Over the past two years, we have achieved remarkable economic and social benefits by demonstrating the promotion of rhizobium technology in leguminous crops. In more than 100 counties of East China Sea, Xinyi, Ganyu, Taixing and other counties in Jiangsu Province, the comparative experiments on more than 100 designated plots showed that the average yield of peanut inoculation than non-inoculated bacteria was 11.4% and 16.8% respectively Mu peanut fruit increase in four or more than 50 pounds. Among them, Taixing County, in 1983, inoculated 8,700 mu of rhizobia with an average yield of 51.1 kg per acre (yield increase rate
