我们于1981～1983年共引进多年生豆科牧草8个属,14个草种,66份材料;禾本科牧草13个属,27个草种,44份材料。通过三年的观察,我们初步认定适应我地栽培的牧草豆科有。紫花苜蓿、沙打旺;禾本科有:无芒雀麦、羊草、冰草,此外红豆草、偃麦草也是很有发展前途的新草种。但究竟哪些品种最适宜我地栽培,仍然是一个亟待解决的问题,因此我们在引种的基础上,于1984～1986年开展了11个优良紫花苜蓿品种、9个无芒雀麦品种、2种沙打旺、6个冰草的 We introduced a total of eight genera of perennial leguminous forages, 14 grass species and 66 materials from 1981 to 1983; 13 genera of gramineous pasture, 27 grass species and 44 materials. After three years of observation, we tentatively identified forage legumes adapted to our cultivation. Alfalfa, sand prosperous; grasses are: Brome grass, Leymus chinensis, ice grass, in addition to sainfoin, Thinopyrite is also a promising new species of grass. However, it is still an urgent problem to solve which species is most suitable for cultivation. Therefore, on the basis of introduction, we carried out 11 fine alfalfa varieties, 9 Bromus inermis species and 2 species Sand playing Wang, 6 ice grass
