摘要
木本固氮植物不仅具有固氮能力,而且大多数木本固氮植物具有很多的用途。随着大面积人工速生丰产林的发展,森林土壤肥力逐步下降,充分认识木本固氮植物资源的生物学特性,利用生物固氮技术,既有利于提高森林生产力,又不会对自然造成环境污染。黑龙江主要木本固氮植物资源的生物学特性,及其开发利用价值进行了初步的探索。
Nitrogenfixing trees not only has firm nitrogen ability,but also has a lot of usefulness.With the development of large area being fastgrowing and highyielding forest,forest soil fertility drops progressively,utilize biological nitrogen fixating fechniques will improve forest productivity and not be to causing the environmental pollution.For this reason,we carry on preliminary exploration in main woody firm nitrogen tree species resources and developing utilizing of Heilongjiang Province.
