为了充分发挥花生根瘤菌共生体的固氮作用,不断提高我省花生的产量并改进其品质,三年来,我们对高效根瘤菌株的引种鉴定和有效应用技术进行了研究。我省五个地区(旅大、锦州、本溪、阜新、沈阳)试验示范面积由1978年的2.5亩,1979年的800亩,到1980年的约47000亩,占全省花生播种面积的3％左右。某些单单接种面积比重较大。如黑山县芳山镇公社、义县张家卜公社、本溪偏岭公社法台五队等接种面积已占该社、队花生播种面积的1/2以上。现收试验示范情况分述如下:一、花生根瘤茵株的引进和鉴定:在我省根瘤菌肥技术协作网的统一布置下,
In order to give full play to the rhizobium colonization of peanut rhizobium synergistic effect, and continuously improve the yield of peanut in our province and improve its quality, three years, we introduced the efficient identification of Rhizobia strains and the application of effective technology. The pilot demonstration area in five regions of our province (Luda, Jinzhou, Benxi, Fuxin and Shenyang) was 2.5 mu in 1978, 800 mu in 1979 and 47,000 mu in 1980, accounting for 3% of the peanut sown area in the province. about. Some single area of ?? a larger proportion of inoculation. For example, Fangshan Township Commune in Heishan County, Zhangjiapu Commune in Yixian County and Panying Piedmont Commune in Benxi County accounted for more than one half of the sown area of peanut communities. Acceptance of the pilot demonstration of the situation are described as follows: First, the introduction and identification of peanut root nodules strain: In our province under the unified arrangement of rhizobium fertilizer technology collaboration network,
