摘 要:沙冬青是我国非常重要的珍稀濒危植物,有着极强的抗逆性,但自然更新慢且种子资源极其匮乏,长期以来一直面临着培育技术上的难题,使其无法发挥应有的价值。只有从提高其抗逆性入手,才能从根本上解决沙冬青培育技术方面的问题,才能达到保护珍稀濒危物种和综合开发利用的双重目的。从抗旱、抗寒、抗风、抗虫及耐盐几方面综合分析目前沙冬青在抗逆性研究方面的进展,同时对种子生产、播种育苗方式、无性繁殖、移栽育苗技术等几个方面评述目前沙冬青栽培技术方面的研究现状,并就此提出了目前沙冬青抗逆性和培育技术研究方面存在的不足以及亟待解决的技术问题。Ammopiptanthus Cheng f. is a very important species which is rare and endangered in China and its stress-resistance is very weU. But the rate of itsnatural renew is so slow and seeds resource is very deftcient. The culture technology of Ammopiptanthus Cheng f. is so hard that limited it to play its role. Only in the way of improving its stress-resistance, the problem of cultivation technology can be solved, and it can be protected and used well. It was analyzed that the research advance of stress - resistance comprehensively in these ways of drought-resistance, cold-resistance, wind-resistance, pest-resistance and salt-tolerance in the article. Also it was discussed that current situation produce, the ways of planting, agamogenesis and aspects and technology problem to be solved urgentl of studies on culture technology in the aspects of seeds transplanting. So, the existing research shortage of two y were pointed out.
