| 摘 要： | 沙柳是库布齐沙漠重要的生物与生态资源之一。通过对沙柳扦插苗进行生根粉（ABT）、保水剂、有机肥和‘四枝一穴’栽植密度的不同处理后，连续3 a对其高生长、基径生长、生物量及平茬后枝条萌发数进行了测定。对测定结果的分析发现：与对照相比，四种处理都能够不同程度地提高沙柳的高生长、基径生长、生物量及平茬后枝条萌发数量。其中保水剂的作用最好，使沙柳的成活率、平茬后的枝条数和生物量分别提高了61.0%，70.4%和71.4%。

| Abstract: | Salix psammophila is one of the important biological and ecological resources in Hobq Desert. Experiment for three years showed that compared to a control the treatments of rootone (ABT), water retention agent and manure application, and a planted density of four individuals in each hole, could significantly improve the survival rate, height, basal diameter, biomass production and sprouted branch number of Salix psammophila. Cutting in combination with water retention agent could greatly increase the survival rate, biomass and sprouted branch number significantly (P<0.05) by 61.0%, 70.4% and 71.4%, respectively. Any of these four treatments could be adopted as a means to promote Salix psammophila production. |
