| 摘 要： | [Objective] The study aimed to reveal the biological nitrogen fixation capacity by sugarcane from Brazil under the ecological conditions of Guangxi,and to provide reference for study on the biological nitrogen fixation capacity by sugarcane and related generalization and application. [Method] The 15N isotopic fertilizer was solely applied on plants of three sugarcane cultivars planted in greenhouse with no other fertilizer forms applied,meanwhile virus-free stem seedling was regarded as control,to measure their biological nitrogen fixation capacity using 15N isotope. [Result] The nitrogen fixation rate of B8 from Brazil reached 26.91%,while Guitang 11 and RIC16 presented no or poor nitrogen fixation capacity. [Conclusion] The sugarcane cultivar B8 from Brazil showed some nitrogen fixation capacity under the ecological conditions of Guangxi.
