河南豆科饲用植物资源研究

河南省地处中国南北气候过渡地带，植物区系研究具有独特的地理学意义。为了有效开发利用该区域豆科饲用植物资源，通过物种调查统计，对区域豆科饲用植物的资源现状、属种组成、植物区系和地理分布及饲用价值进行分析。结果表明：河南豆科饲用植物共有41属136种。其中优势属和少种属占区域豆科植物区系属种的主体，分别占总属数60.97%和总种数的81.62%；区系地理成分以温带和热带为主要分布型，反映了河南豆科饲用植物区系分布与其处于过渡气候相适应的特征。河南豆科饲用植物的饲用价值总体较高，优良和中等豆科饲用植物种数占总种数的89.71%，下等和毒草占总种数的10.29%，并对其开发利用方式提出建议。

Study on the Leguminosae Forage Plant Resource in Henan

Henan Province was located in the North-South climate transition zone, and the studied of plants flora have exclusive geographical significance. Through investigation and statistics of natural legume forage species, in order to effectively exploit the regional forage legume resources, it was analyzed that the family and genera composition and the geographical elements and the feeding value analysis in Henan. The results showed that, there were 136 species of natural plants, which belonged to 41 genera in Henan. Among them, the main body form of the local legume forage flora was the dominant genera and the few genera, which the flora advantage phenomenon was very obvious. The two generas were 60.97% of the total generas number and 81.62% of the total species number. In the geographical elements of the plants flora, the temperate zone and the tropic with genera distributional type were in a dominant position, which expresses the adaptable characteristics between the distribution of flora and the climate zone. There was good value to leguminous forage in Henan, the exceptional and the moderate was 89.71% of the total species. The inferior and the poisonous was 10.29%. Some suggestions were put forward on their utilization and protection.
