摘　　要：为了探索在旱作条件下人工灌丛草地的建植技术措施,研究采用带状覆膜直播技术种植科尔沁型华北驼绒藜和鄂尔多斯草木樨状黄芪,在雨季进行种植,播种后膜上灌水1次,每公顷灌水15t左右。结果显示,科尔沁型华北驼绒藜出苗率达到95%,翌年测定成活率达98%;其干草平均产量翌年为4825kg/hm2、第3年为8941kg/hm2、第4年为12748kg/hm2。鄂尔多斯草木樨状黄芪出苗率达到75%,翌年测定成活率达95%;其干草平均产量翌年为927kg/hm2、第3年为1421kg/hm2、第4年为2275kg/hm2。该项技术解决了干旱、半干旱地区旱作人工草地植物的出苗、保苗困难问题,对提高灌丛草场土地利用率、提高草场产量和质量、增加草地持久力和耐牧性具有重要的意义。In order to effectively research the planting techniques in artificial shrub grassland,Ceratoides arborescens （Losinsk.）Tsien et C. G. Ma cv. Keerqinxing and Astrogalus melilotoides Pall ev. Ordos were used under direct seeding conditions,during rainfall season with irrigation after seeding.The results show that, germination rate ofCeratoides orborescens （Losinsk.）Tsien et C. G. Macv. Keerqinxing is 95%, with survival rate of 98% in next year, and average output of 4 825 kg/hm2, 8 941 kg/hm2 and 12 748 kg/hm2 in second, third and fourth year; whereas Astragcdus melilotoides Pall. cv. Ordos get 75% ,95% ,927 kg/hm2,1 421 kg/hm2 and 2 275 kg/hm2 respectively. This technique solves the difficulties of seeding under arid and semiarid conditions, it has important practical significance to sustainable development of grassland and animal husbandry and to the ecological environment improvement.
