优良沙生灌木育苗及造林技术研究

Seedling-raising and Afforestation Technology of Superior Sandy Shrubs

在科尔沁沙地南缘对小叶鼠李、桃叶卫矛和杠柳3种优良乡土沙生灌木进行了播种育苗和造林技术试验,通过对3种灌木的生长表现进行测定,结果表明:3种沙生灌木的生长指标均与对照胡枝子持平或略高于对照,在沙地造林成活率达95%以上,且经济效益可观,示范推广效果良好。

Experiments of the sowing and seedling-raising ＆ afforestation technology of Rhamnus parvifolius, Evonymus bungeanus and Periploca sepium were conducted in the south edge of the Horqin Sandy land.Growth of three shrubs were determined.Result shows that the growth indices of the three shrubs were equivalent or slightly higher than that of lespedezabicolor.The survival rate of shrubs are above 95% ,with considerable economic bene-fit and optimal demonstration effect ;it can be extended as optimal sandy shrubs in three northern region.
