锡林郭勒草原是我国著名的牧区之一,地域辽阔,野生牧草资源十分丰富。为了进一步摸清该地区牧草的区系组成,为合理发掘、利用该地区牧草资源奠定科学基础,我们于1973—1975年对该地区的野生禾本科牧草进行了系统地调查和研究。现将其中雀麦属牧草的调查材料加以整理,为进一步发掘和利用该属牧草供作参考。一、雀麦属牧草的种类根据文献记载,雀麦属植物在全世界有100多种,主要分布于温带,是饲用价值较高的一类牧草,其中广泛分布的无芒雀麦(B.inermis Leyss)就是著名的优良牧草之一,目前有许多国家进行栽培。雀麦属植物在我国计有14种及1变种,广泛分布于全国各地。据我们调查,在锡林郭勒草原上,雀麦属牧草有4种及1变种,其中包括1新种,即内蒙古雀麦(B.intramongolicus Y.ch.tsiang)。
Xilin Gol Grassland is one of China’s famous pastoral areas, vast territory, wild forage resources are very rich. In order to further understand the floristic composition of the forage in the area and to establish the scientific basis for the reasonable excavation and utilization of forage resources in the area, we conducted a systematic investigation and study of the wild gramineous forage in the area from 1973 to 1975. The investigation material of the brome grass is sorted out for further exploration and utilization of the pasture for reference. First, the species of brome grass According to the literature, there are more than 100 species of bromes in the world, mainly in the temperate zone, is a higher forage value of a class of forage, which widely distributed in the brome .inermis Leyss) is one of the famous fine forages, many countries are currently cultivated. There are 14 species and 1 varieties of bromeliads in our country, which are widely distributed all over the country. According to our investigation, there are 4 species and 1 species of Brome grass in the Xilingol Grassland, including 1 new species, B.intramongolicus Y.ch.tsiang.
