| 摘 要： | 采用野外实地扦插试验方法对浑善达克沙地2种立地类型（平缓沙地和风蚀坑）上黄柳（ Salix gorde-jve ii）再生沙障插穗个体的长度、栽植密度、采集时间和扦插时间与其成活率的关系进行了研究。结果显示：平缓沙地插穗长度为50 cm较为适宜，成活率可达84．41％，风蚀坑插穗长度为65 cm较为适宜，成活率达84．83％。2种立地类型下，栽植密度为10根· m－1时的成活效果较好，成活率分别为83．75％和75．25％。平缓沙地和风蚀坑扦插的冬贮条均较现采条的成活率高，成活率分别为91．25％和84．58％，即插穗在秋季采集较好。春季扦插较秋季扦插更有利于成活，平缓沙地上春季扦插的冬贮条与现采条的成活率为91．25％和83．75％，分别较秋季扦插的现采条的成活率高22．42％和14．92％。

| Abstract: | We studied the relations between the survival rate and cuttings individual indicators including cuttings length , planting density , acquisition and setting time of aS lix gordejevii living sand barrier in gentle desert and blowouts in Hunshandake sandy land .The barrier grew well with 50 cm cuttings length in gentle desert , and the survival rate reached 844.1 %, So did the barrier with 65cm in blowouts , and the survival rate reached 84.83%.As planting density was 10 plants per meter in gentle desert and blowouts , the barrier grew better with the survival rate of 83.75%and75 .25%.The cuttings were stored in winter and set in spring with the survival rate of 91.25%and 84.58%, respectively, and grew better than those picked and set in spring in the two site types .The cuttings picked in autumn grew better .The cuttings set in spring grew better than that in autumn .The cuttings stored in winter and set in spring and ones picked and set in spring , with the sur-vival rate of 91.25%and 837.5 %, were 22.42%and 14.92%higher than those picked and set in autumn , respectively. |
