摘 要: 为实施对柽柳(Tamarix chinensis)的广泛栽种,对其生长繁殖方式及生理特性进行研究。在对柽柳繁殖方式的比较中,设一组对照,在每个浓度梯度下设置10个重复,其中扦插和种子繁殖各5株。共分8个盐浓度梯度:对照组,0.8%,1.1%,1.4%,1.7%,2.0%,2.3%,2.6%, 在pH值为8时培养。实验发现柽柳扦插繁殖比种子种植成活率高得多。因此,扦插可以作为繁殖柽柳的一种简单有效的方法。此外,研究还发现:在含盐量为0.8%~2.6%的土壤中,柽柳生长量随土壤盐浓度的增高呈下降趋势。
关 键 词: 生态学;柽柳;繁殖;扦插繁殖;成活率

Abstract: To widely propagate Tamarix chinensis, this experiment researched the species on its reproductive ways and physiological characteristics. During the comparison of its reproductive ways, one group Chinese Tamarisk was used as contrast, ten duplications were set in each salt gradient group, with five plants in each duplication. Eight salt gradients were planned in the experiment: contrast group, 0.8%, 1.1%, 1.4%, 1.7%, 2.0%, 2.3%, 2.6%, and the pH value was controlled at 8. It is found that cuttage is more available than seeds though the work. So cuttage can be used as a simple and effective way to breed the plant. In addition, it is also found that Chinese Tamarisk thrives best in soil with 0.8%~2.6% salty degree, and it grows less in higher salt levels.
Key words: ecology; Tamarix chinensis; propagation; cuttage; survival rate
