我所于1984年在静宁县设点开展了干旱半干旱地区牧草引种试验,先后引入国内外牧草和饲料作物108种,试种成功70种。其中,豆科24种,禾本科41种,菊科1种,藜科1种,十字花科3种。经5年的引种、品比试验和区域性推广种植,最后筛选出适宜我省东部干旱半干旱地区种植的优良牧草品种21个,适宜半湿润地区种植的牧草品种7个和可作草坪建植和庭园绿化的牧草品种14个,为该区的牧草引种提供了依据。一、多年生豆科牧草1.紫花苜蓿(Medicago sativa L.)参试的紫花苜蓿有本地、平凉和和田三种苜蓿。播种当年种子均不能很好成熟。第二年开始,每年于3月下旬或4月初返青,8月下旬至9月上旬种子
In 1984, I set up a pilot plant in arid and semi-arid areas at Jingning County. It introduced 108 domestic and foreign pastures and forage crops and succeeded in cultivating 70 species. Among them, 24 legumes, 41 gramineae, 1 Compositae, 1 Chenopodiaceae and 3 Cruciferae species. After 5 years of introduction, product ratio test and regional popularization and cultivation, we finally screened out 21 good forage varieties suitable for planting in the arid and semi-arid areas of eastern province, 7 forage varieties suitable for semi-humid areas and grass planting And fourteen greening pasture species, providing the basis for introduction of forage in the area. First, the perennial legume forage alfalfa (Medicago sativa L.) Alfalfa tested three local, Pingliang and Hotan three kinds of alfalfa. Seeds were not sown well matured. Beginning the second year, every year in late March or early April green, late August to early September seeds
