| 摘 要： | 通过对湖南省6种有代表性的油茶林分联合固氮菌的调查，研究了不同林地根际联合固氮菌的分布规律，筛选出了优良的固氮菌株并对其固氮效能进行了测定分析。结果表明：不同油茶林分根际联合固氮菌的数量存在显著差异，野生林较人工林高，山地较圃地高，青壮林较幼龄林高；根据固氮效能分析可知，从油茶林分中可分离到高效固氮菌株，高效固氮菌株在野生青壮林根内部分布最多。

| 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 ability 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 distribut... |
