摘要: <正>对豆科树种的评价和研究应明确它是否结瘤固氮,过去认为豆科植物都能结瘤固氮是不正确的。近年来的统计表明,豆科植物有700多属近20000种,已进行过结瘤观察的不过3000余种,其中结瘤的占92%。含羞草亚科结瘤的占调查种数的90%,蝶形花亚科的为98%,而苏木亚科仅为28%。 苏木亚科约177属,其中除铁刀木属(Cassia)的600多种中有一定数量草本植物和灯心草豆属(Hoffmanseggia)的45种中有少数多年生草类外,其余175属几乎全是各种乔木和灌木树种。苏木亚科中已知结瘤的70多种中,一半以上又都是铁刀木属中的一些草本植物,可见苏木亚科的绝大部分树种都不结瘤,因而在生产中选用豆科树种时应注意这一问题。

Abstract: It is estimated that leguminous trees and shrubs in China have approximately 763 species, here we enumerate only 212 species on the list. The list is a ready guide to 160 species which have been positively reported with nodulation, 44 species reported not to nodulate, 8 species both reported to nodulate and nonnodulate.An appendix in tabular form (Table 2), listing the genera, is alphabetically arranged, but segregated according to subfamily. This appendix enumerates the species in each genus and the number of nodulated and nonnodulatcd species reported. In the total counts, we have omitted synonyms. Blank spaces indicate the voids in our knowledge. The appendix ends with a computation of the total numbers of genera and species reported within the respective subfamily.
