生物固氮是大气中氮素向森林生态系统中输入的一个重要途径。木本共生固氮是重要的固氮资源,非豆科木本固氮植物结瘤范围广,随着新的种属的不断发现和弗氏放线菌的分离成功,非豆科共生固氯已成为当前生物固氮研究中的活跃领域之一。本文较全面地介绍了我国非豆科固氮树种在林业上的应用研究现状,并指出了有待进一步研究的问题。
Biological nitrogen fixation is an important way to input nitrogen into the forest ecosystem in the atmosphere. Woody symbiotic nitrogen fixation is an important nitrogen fixation resource. Non-leguminous woody nitrogenous plants have a wide range of nodulation. With the continuous discovery of new species and the successful isolation of Actinomyces, the non-leguminous symbiotic chlorine fixation has become the current One of the active areas in biological nitrogen fixation. This paper introduces the status quo of forestry research on non-legume nitrogen-fixing species in China and points out the issues to be further studied.
