荒漠化山地侧柏大苗造林试验

辽西半干旱荒漠化山地,由于土质瘠薄,植被稀疏,造林难度大,在这类山地上通过选择极耐干旱树种侧柏(Platycladus orientalis)3～4年生大苗进行造林试验。结果表明,应用3～4年生侧柏大苗在中度、重度荒漠化山地上造林,成活率都在95%以上,保存率达到了100%,林木生长良好,造林获得了成功,从而打破了在荒漠化中度或重度山地上只能以封山育林为主、栽灌种草为补的保守治理模式,为荒漠化山地造林提供了一项切实可行的新举措。

Afforestation Experiments of Seedlings for Platycladus orientalis on Barren Hills and Wastelands

On semiarid barren hills and wastelands of western Liaoning Province,due to barren soil,sparse vegetation,difficult to afforestation,in such mountain the extremely drought-resistant species——3-4-year-old Platycladus orientalis seedlings were selected to afforest.Result shows that :using 3-4-year-old Platycladus orientalis seedlings to afforest on moderate & severe barren hills and wastelands,the survival rate are above 95%,and preserving rate reach 100%;forest grow well;reforestation has been successful;conservative control model,mainly to hill-closing as a supplement to plant shrub & grass on moderate & severe barren hills and wastelands,were broken;it provides a practical new initiatives for re-afforestation on barren hills and wasteland.
