花生根瘤菌在我国的研究和应用已较多,效果也较好。据中国农科院油料作物研究所报道,花生使用根瘤菌拌种,平均每亩可增加72斤(荚果,下同),增产19.5％。荆州地区花生面积比较大,调查本地区花生自然结瘤状况,研究分析人工接菌的肥效,对于推广使用花生根瘤菌,提高花生结瘤量和固氮能力,促进花生高产具有一定意义。现将调查及试验结果按理如下。
Peanut rhizobia in our country has more research and application, the effect is better. According to the Institute of Oil Crops, Chinese Academy of Agricultural Sciences reported that peanut dressing rhizobia, an average of 72 kg per mu can increase (pod, the same below), an increase of 19.5%. The peanut area is relatively large in Jingzhou area. The natural nodulation status of peanut in this area was investigated. Studying and analyzing the effect of artificial inoculation was of great significance for promoting the use of peanut rhizobia, increasing the nodulation amount of peanut and fixing nitrogen, and promoting the peanut high yield. Now the survey and test results according to the following rationale.
