摘  要：
以塔克拉玛干沙漠南缘疏叶骆驼刺(Alhagi sparsifolia)离体根系为研究对象,在策勒沙漠-绿洲过渡带人工控制试验田设置3种根长处理、3种种植深度处理、5种灌溉处理,进行三因素完全交互试验。结果显示,在其它两种影响因素相同情况下,疏叶骆驼刺出苗率随根长的增加而减小,根长为10cm时出苗率最高;随着种植深度的加深出苗率逐渐增大,种植深度为30cm时出苗率最高;出苗率在灌水10m~3·m~(-2)、7月30日灌溉一次处理下最高。除灌水处理与种植深度的交互作用外,其它影响因素及其交互作用对出苗率影响差异显著(P<0.05)。研究得出,10cm根长、30cm种植深度、10m~3·m~(-2)灌溉一次为最优处理组合。

摘  要：
We studied the effect of different treatments on the emergence in vitro propagation of Alhagi sparsifolia root segment in the southern fringe of the Taklimakan Desert.The purpose of this study was to provide a new A.sparsifoliavegetation restoration technology.We compared the emergence under three-factors(three kinds of root length,three kinds of planting depth and five kinds of irrigation treatments)fully interactive treatments.The results showed that if keeping the other two factors unchanged the emergence rate was reduced with root length increase,the emergence rate achieve the highest at 10 cm root length.The emergence rate increased with planting depth increasing.Emergence rate reached the highest with planting depth of 30 cm.Emergence rate reach the highest under irrigation regime of 10m~3·m~(-2) and once on July 30.In addition to the interaction between irrigation treatments and planting depth,there were significant differences among all interactive processing among three factors.In conclusion,10 cm root length,30 cm planting depth,10 m3·m~(-2)(once)irrigation treatment are the optimal planting pattern.
