治沙植物旱生结构及生理特性的研究

A Research on the Xerophytic From and Physiologyical Characterstic of Sand-control Plants

研究植物的旱生结构和一理特性，为干旱沙区造林提供科学依据。供试的６种植物普遍具有典型的旱生结构和具有束缚水含量高、束缚水与自由水比值大，水势低，临界饱和亏值大等生理指标，但由于植物种的不同，这生理指标又各具有互为消长的特性。

The scientific study of the xerophytic form and physiologyic characteristic of plants is the basis afforestation in the dry sand regions. The 6 sorts of plant tested share the common characteristics xerophytic form and high bounded water content, consideable ratio between bounded and free water contents, low water potential and the considerable critical saturation deficient value. And the above indices of different species of plants have the characteristic of mutual increase or edcrease.
