中文摘要	以晋北半干旱风沙区为研究区域,釆用漏斗状覆膜技术造林,探讨覆膜对不同密度(株行距分别为2 m2 m、3 m3 m、4 m4 m、4 m6 m)新疆杨生长和光合特性的影响.结果表明,漏斗状覆膜技术对不同密度新疆杨生长和光合特性有显箸影响(P<0.05),2 m2 m密度的新疆杨生长性状和光合特性表现最优,不同密度的树高、胸径、当年生长量、成活率、叶绿素含量、净光合速率表现出随密度减小而递减的规律,相关分析显示树高、胸径与净光合速率的相关系数分别为0.991、0.863,与叶绿素含量的相关系数分别为0.858、0.584.综合分析结果,在晋北半干旱风沙区,覆膜面积所占比例显著影响树木的成活与生长,新疆杨初植密度为2 m2 m且漏斗状覆膜效果最佳.
英文摘要	Taking the semi-arid sandy region of northern Shanxi Province as research area,the effects of funnel-shaped film mulching on the growth and photosynthesis of Populus bolleana seedlings with different planting densities (22,33,44,and 4 m6 m) were examined. Significant influences (P<0.05) were observed. The growth indexes and photosynthetic characteristics were the best in the density of 2 m2 m. The tree height (H),diameters at breast height (DBH),annual growth,survival rate,chlorophyll content (ChlC) and net photosynthetic rate (P_n) decreased with the decrease of planting density. Correlation analy-sis showed that the correlation coefficients were 0.991 (between H and P_n),0.863 (DBH and P_n),0.858 (H and ChlC),0.584 (DBH and ChlC),respectively. Over all,the proportion of film mulching significantly affected the survival and growth of P. bolleana,and the initial density of 2 m2 m with funnel-shaped film mulching was suggested in semi-arid sandy area of Northern Shanxi Province.
