Abstract: The division,rooting,rapid multiplicaion and regeneration of the axillary buds,and the transplanting of seedlings of Nitraria L.were studied systematically,So was the cultural difference between N.tungutorum and N.roporowskit.In order to save chemical reagents and cultural time,and to improve the efficiency of culture,we studied the nutrient Lauid culture of rooting.The result showed that for N.tangutorum,most suitable division medium is "Ms+BA2.0ppm"+IBA0.6ppm";best rooting meedlium is "l/2Ms+IBA0.6ppm",the transplanting Survival rate of 20 day seedlings is more than 95%;N.roporowskii is obviously different from N.tangutorum in division and the rooting.For the divisional rate and the rooting rate to be highest,the concentration of IBA must higher.As for the liquid rooting culture,the best nutrient lipuid is "1/4MS+IBA0.6ppm".
