东北西部薪炭林主要树种生理特性的研究

在东北西部干旱或半干旱地区不同立地条件下,为了给正确选择营造薪炭林的树种提供依据,从紫穗槐、胡枝子、柳、榆、杨、沙棘等树种的生理特性方面进行了研究。通过测定这些树种的光合作用、叶绿素含量及水分状况,选择了一些光合速率高、叶绿素含量多、抗旱性强的树种。经过几年的测定和选择,通过综合分析,认为在内蒙北部和吉林西部应大力营造紫穗槐、胡枝子等;在黑龙江省西部应发展柳、榆、杨等;在辽西发展紫穗槐、沙棘等是可行的。

STUDY ON THE PHYSIOLOGICAL PROPERTIES OF THE MAIN FUELWOOD TREE SPECIES ON THE WEST OF THE NORTHEAST CHINA

Some physiological properties of the tree species such as Amorpha fruticosa, Lespedeza bicolor, Salix matsudara, Ulmas pumila, Popalus simonii, Hippophae rhamumoides etc. growing in arid or semiarid area on the west of Northeast China were studied to determine which species of fuelwood were suitable to be planted in these areas. From the photosynthesis, chlorophyll content, and water situation of some tree species, the tree species with high rate of photosynthesis, high cholorophyll content and great drought resistance were selected. After investigation and selection for several years and by complex analysis, the authers think that it is recommendable to plant many of Amorpha fruticosa, Lespedeza bicolor, ect.. In the north of Inner Mogolia Autonomous Region and in the west of Jilin province to develop Salix matsudana, Ulmus pumila, Populus simonii ect. in the west of Hcilongjiang province and to develop Amorpha fruticosa, Hippopheae rhamumoides ect. in the west of Liaoning province.
