中文摘要	为探讨抗旱保水袋在废弃采石场造林中的应用效果,通过室内试验和室外盆栽试验研究了抗旱保水袋性能及对容器苗生长的影响。结果表明:大袋保水袋的吸水速率和吸水倍数比小袋保水袋分别增加1.4倍、1.9倍,在蒸馏水溶液下的吸水速率和吸水倍数比自来水分别增加0.6倍、0.1倍;大袋保水袋的保水率大于小袋保水袋;保水袋能显著增加渣土土壤体积含水量,比对照高1.29倍,苗高平均比对照增加2.36cm,成活率平均比对照增加69.5%,出现死亡天数平均比对照推迟12d。结论得出,抗旱保水袋是干旱、半干旱及半湿润地区废弃采石场困难立地提高造林成活率并促进植被恢复的一种有效方法。
英文摘要	In order to study the performance of water retention bag and its application to the afforestation of waste quarries,we did a pot experiment at laboratory to analyze the different specification and dosage of it used in the container seedling. The results showed that the water absorption rate and water absorbency of the big water retention bag were about 1. 4 times and 1. 9 times greater than the small one; the water absorption rate and water absorbency of distilled water were about 0. 6 times and 0. 1 times than tap water. The water retention rate of the big bag was higher than the small bag. The volumetric soil and water content,the height of container seedling and the survival rate of water retention bag were significantly higher than the control. The volumetric soil water content was 1. 29 times higher than the control; the height of container seedling was 2. 36cm more than the control; the survival rate was 69. 5% more than the control; the dead day was delayed 12d than the control. Therefore water retention bag is fit to improve the survival rate of trees and enhance the revegetation in hard site of the waste quarry in arid,semiarid and semi - humid regions.
