一、前言四川省大部地处亚热带,天然草地(纯牧区)主要分布于西部高原地区,畜牧业比较发达。盆地边缘草地环绕,多属山区,也有不少连亘成片和面积大小不等的草山草坡,蕴蓄着发展农区畜牧业的巨大潜力。为了探寻这类农区野生牧草、饲料植物的种质资源,我们于1980年10～12月到乐山、达县、万县三个地区五个县十个公社,着重采集了野生饲料作物种子和标本,其中种子83号,标本203号,并对该地区与牧业有关的
I. INTRODUCTION Most of Sichuan Province is located in the subtropical and natural grassland (pure pasturing area), which is mainly distributed in the western plateau area with more developed animal husbandry. The edge of the basin is surrounded by grasslands, mostly in the mountainous areas. There are also many grassland and grass slopes connecting the villages and areas of different sizes and have great potential for the development of animal husbandry in the rural areas. In order to explore the germplasm resources of wild forages and feed plants in this kind of agricultural areas, we visited 10 communes in 5 counties in Leshan, Daxian and Wanxian from October to December 1980 and collected wild feed crop seeds and Specimens, of which seed No. 83, specimen No. 203, and the area and animal husbandry related
