榆林市长柄扁桃引种栽植技术探讨

Discussion on the Introduction and Planting Techniques of Prunus pedunculata in Yulin City

以榆林市长柄扁桃为例,研究得出,长柄扁桃在盖沙黄土、黄土地、半固定沙条件下保存率可达80%以上,株高、冠幅长势较好;在固定沙地、流动沙地条件下保存率及长势较差;长柄扁桃、紫穗槐混交林较长柄扁桃纯林长势更好。据此总结出适宜推广的长柄扁桃造林技术,提出了大面积发展长柄扁桃林的合理化建议。

Take Yulin City as an example,the study showed that the preservation rate of Prunus pedunculata could reach more than 80% under the condition of sandy loess,yellow soil and semi-fixed sand,and the growth of plant height and crown width was better.The retention rate and growth rate were poor in fixed sand and moving sand.The growth of mixed Prunus pedunculata and Amorpha fruticosa forest was better than that of pure Prunus pedunculata forest.Based on this,the paper summarized the planting techniques suitable for extension,and put forward some reasonable suggestions for the development of Prunus pedunculata forest in large area.
