Abstract：Ammopiptanthus Cheng f. is a very important species which is rare and endangered in China and its stress-resistance is very well. But the rate of itsnatural renew is so slow and seeds resource is very deficient. 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 of studies on culture technology in the aspects of seeds produce, the ways of planting, agamogenesis and transplanting. So, the existing research shortage of two aspects and technology problem to be solved urgently were pointed out.
