Botanical Characteristics and Resource Accumulation of Three Vicia Species from Northeast of Qinghai-Tibetan Plateau
Vicia sativa,V.amoena and V.bungei not only can fix nitrogen strongly,but also are important and fine pastures in the Qinghai-Tibetan Plateau (QTP).Meanwhile,it is better bee and flower plants because of drought and cold resistance,long florescence,colored flower,etc.So,it has greater ecological and social economic values.The botanical characteristics,ecological environment,population characters and resource accumulation of Vicia sativa,V.amoena and V.bungei in the QTP were studied through a method of pointing field and least sample and statistics in this paper.The result showed that there were some extent difference on botanical characteristics,ecological environment and population characters among the three Vicia species.Furthermore,the total resource accumulations of the three Vicia species in Qinghai province are 0.46 × 106,0.23 × 106 and 0.27 × 106 kg,respectively.The results suggested that the total accumulation of the three Vicia species is not high,so it should be introduced and domesticated in order to realize their artificial breeding and increase resource reserves.This can protect the fragile ecological environment in Qinghai province,and even the Qinghai-Tibetan Plateau.Furtherly,the resources of three Vicia species can also be effectively protected and reasonably developed and utilized.
