在甘蔗根际的微生物中，固氮菌是重要类群。选择适宜的固氮菌接种甘蔗有可能取得很好的经济效益。几十年来国内外学者经常进行这方面的研究，取得初步成效。现已从甘蔗根际分离出十几种固氮菌，也曾在盆栽和小面积田间接种试验中初步肯定了固氮菌的应用潜力。采用基因工程选育
In the rhizosphere of sugarcane, azotobacter is an important group. Select the appropriate nitrogen-fixing bacteria inoculated sugar cane may achieve good economic benefits. For decades, domestic and foreign scholars frequently conducted research in this area and achieved initial success. A dozen of nitrogen-fixing bacteria have been isolated from the cane rhizosphere. Potential applications of nitrogen-fixing bacteria have also been initially affirmed in potted and small-area field inoculation experiments. Using genetic engineering breeding
