巴氏梭菌(Clostridium)是法国微生物学家巴斯德在1840年从土壤中分离出来的,故称巴氏固氮梭菌。属厌氧性非共生固氮细菌,也叫丁酸发酵芽孢杆菌。在自然界和土壤中分布很广,数量较多,每克土壤约含巴氏梭菌10—100余万,是土壤中其它固氮菌数量的100—10,000倍。所以巴氏梭菌在土壤生物固氮中所起的作用是不可忽视的,在农业生产上应大力推广应用。我们在1978年用巴氏梭菌液浸小麦种,取得增产效果。
Clostridium (Clostridium) is a French microbiologist Pasteur from the soil in 1840 isolated, it said Clostridium pasteurianus. Anaerobic non-symbiotic nitrogen fixation bacteria, also called Bacillus butyricum. In nature and the soil is widely distributed, the number of more, per gram of soil about Clostridium perfringens 10-100 million, is the number of other nitrogen-fixing bacteria in the soil 100-10,000 times. Therefore, Clostridium perfringens in the role of soil biological nitrogen fixation can not be ignored, in agricultural production should be vigorously promote the application. We in 1978 with pasteurized liquid immersion wheat, yield increase.
