摘要
通过对唐古特白刺在不同基质中的育苗试验,结果表明:河沙、耕作土加羊粪按4∶1比例配制、耕作土加锯末按1∶1比例配制和森林土做基质比耕作土的出苗率高,唐古特白刺保存株数均好;河沙基质出苗早,但无后劲,而在混合土中生长后劲足;耕作土加羊粪按4∶1比例配制和耕作土加锯末按1∶1比例配制作基质时唐古特白刺株高最高、主根最长、侧根数最多.
the seeding- raising experiment of Nitraria tangutrorum in different soil was studied. The results showed germination rate and livability of Nitraria tangutwrum in ground substance such as river sand, soil： sheep dung（4：1） , farming soil： sawdust（1：1） or forest soil were higher than that of farming soil; furthermore, among these three ground substance, the time when the seedlings came out in river sand was earlier but the way corp is growing feeblely; in soil： sheep dung（4： 1） and farming soil： sawdust（1：1 ）, individual plant tallness, axial root length and branch root number were better.
