摘要
豆科及非豆科固氮树种是重要的生物固N资源。作为混交树种,在混交林中发挥着改善林地养分及水分状况,维持地力,提高林地生产力,很好地促进主要树种生长的重要作用。
Nitrogen fixation trees of Leguminosae and non-Leguminosae are important biological nitrogen fixation resources. As a species of mixed forests, nitrogen fixation trees play an important role in improving forest land nutrient and moisture status, maintaining soil productivity, enhancing forest land productivity, and accelerating main species growth.
