Abstract: Seven tree species have been choosed for the Study of deep planting in Sand soil．They are Populus×euramericana(Dode)Guinier cv．Sacrau 79，P．X euramericana(Dode)Guinier cv．I-214，P．Xeuramericana cv．Polska-15A，P．Tomentosa Carr．，Ulmus pumila L.，Ailanthus aItissima(Mill) Swingle and Robinia pseudoacacia L．The depth of planting is 50CK，100， 150，200，and 250era respectively．The survival rate，reserVe rate and growth rate have been observed for 5 years．The results Show that the surviral rate of the deep planted poplars is 1.4—9.5 times as high as that of CK (50era)and the re serve rate is 1—8.9 times as high as that of CK．After five years，the tree height and diameter at breast height and diameter at breast he'ight and diameter at breast height of P．Xeuramericana CV．Sacrau，P．Xeuramericana CV．I-214 and P．Tomentosa are 1.34—1.62，1.13—1.22 and 1.08—1.22 times than those of CK respectively．Deep-planted Ulmus pumila has not been found any increases in sUrvival rate and growth rate．Ailanthus altissima and Robinia pseudoacacia are not sukable for deep-planting．The study shows that in sand soil area，if underg round water is deeper than 3m，the depth of planting for poplars Should be 100-150cm，
