四、红壤中的固氮作用关于固氮菌(Agofod acter)在红壤中的分布,国内研究者进行了不少的工作。钱泽澍曾对浙江、贺鹰博曾对海南岛的红壤荒地作过调查,均未发现红壤荒地有固氮菌存在。我们曾对江西不同成土母质上发育的红壤荒地选择了九县25点124个标本做过调查亦未发现有固氮菌存在,这些地点是庐山的含鄱口,九江市郊,新建县的甘家山、生米
Fourth, the role of nitrogen fixation in red soils On the distribution of nitrogen-fixing bacteria (Agofod acter) in red soil, domestic researchers have done a lot of work. Qian Zehui once conducted a survey on the red soil wasteland of Hainan Island in Zhejiang and He Yingbo. None of the red soil was found to have nitrogen-fixing bacteria. We selected 25 124 samples from nine counties in the red soil wasteland developed on different soil-forming parent materials in Jiangxi Province and did not find any nitrogen-fixing bacteria. These sites include the Han Pokou in Lushan Mountain, Ganjianshan in the outskirts of Jiujiang, and Xinjian County ,raw rice
