中文摘要	沙地衬膜试验结果表明：衬膜沙地栽植的棒子松苗木当年平均成活率高于对照地，不同越冬处理的苗木越冬率从大到小为埋土，衬膜深度90cm露地，衬膜深度70 cm露地，不衬膜露地越冬。高生长盘显示出第一年、第二年衬膜苗高于对照苗，而第三年衬膜苗弱于对照苗。灌水量相同的条件下，衬膜苗在生长季节利于苗木旺盛生长；秋冬春季苗地土壤水分过多，地块低洼处的苗木保存率降低，生长盘也较低，对照地苗木则相反．建议通过控制灌水量，积极探索衬膜种植的栽培学技术，创造条件，实行少量多次的定额灌概，是干旱区进一步提高樟子松育苗成活率、保存率的一种新的有效途径．
英文摘要	The seedling cultivation experiments of Pinus sylvestris var. mongolica in film-bottomed sandy land show; the average seedling survive ratio in film-bottomed sandy land is higher than that of the contrast field in first year. The order of seedling survive ratio from big to small under different methods in winter season is seedlings buried by local soil, film-bottomed by depth of 90 cm, film-bottomed by depth of 70 cm and non-buried contrast field. The seedling growth shows it’s higher in film-bottomed sandy land than the contrast field in thefirst and second year, but lower in third year. Under the same irrigation condition, the soil moisture in film-bottomed field is benefit to seedling growth effectively in the growth season; however, much more soil moisture in autumn, winter and spring limits the seedling survive ratio and growth, in the same condition, the contrast field opposites. The suggestions of reducing water capacity through more times irrigation and increasing film-bottomed depth and other factors will improve the seedling survive ratio and growth obviously.
