不同油茶林分联合固氮菌的分离及固氮效能分析
Isolation of associative-nitrogen-fixing bacterium from typical Camellia forests and analysis of nitrogen efficiency
摘要
Abstract
The associative-nitrogen-fixing bacterium was investigated in six typical Camellia forests with different managements , site conditions and ages in Hunan province. Screening nitrogen strains were carried out and their nitrogen a-bility was detected by nitrogen efficiency. The analysis of Azotobacter populations indicates that the wild >the planted forest, mountainous forest > flat (nursery) , the adult forest >the young forest. The analysis of nitrogen efficiency indicated that the largest number of strains was distributed in the roots of wild adult forests. The results proved high nitrogen efficiency strains that can be separated from the Camellia, and it is the foundation to develop and apply bacterial fertilizer.关键词
