Abstract: 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.
