叶面固氮菌首先由荷兰学者Ruinen在印度尼西亚的热带潮湿地区的植物叶面上发现。此后,Ruinen和其他一些科学工作者经过调查指出。不仅在许多热带野生植物和农作物的叶面上和叶鞘中普遍存在固氮微生物,在所有潮湿条件下,如潮湿草原、荫蔽森林及湿生植物叶际也都存在着固氮微生物。迄今已进行过叶面微生物调查的地区。有印度尼西亚的爪哇和苏门答腊、新西兰、苏里南、印度、象牙海岸、尼 Azotobacter is first discovered by the Dutch scholar Ruinen on the foliage of plants in the tropical moist areas of Indonesia. Since then, Ruinen and other scientists have pointed out after the investigation. Nitrogen fixing microorganisms are not only found on foliage and sheaths of many tropical wild plants and crops, but also nitrogen fixation microorganisms in all wet conditions, such as in wet grasslands, shaded forests and wetland plants. To date, foliar microbial investigations have been conducted. There are Indonesia’s Java and Sumatra, New Zealand, Suriname, India, Ivory Coast, Nigeria
