摘要
沙棘是我国干旱、半干旱地区广泛栽植的用于保持水土、防风固沙的主要树种之一,具有良好的经济效益和生态效益。沙棘平茬可以促进养分吸收、减少病虫害、增强生长势。试验研究了沙棘平茬对更新复壮的影响,结果表明：相同树龄沙棘平茬高度以8cm最好,平茬后树高、冠幅及分枝数均较大;同一平茬高度下,以栽植7~8a的沙棘平茬后生长最好,更新复壮效果明显。
With great economic and ecological benefits, Seabuckthorn is an important plant widely used to keep the soil and water and for wind sheltering and sand fixation. Stumping of seabuckthorn can promote the nutrient absorption, reduce the plant diseases and insect pests and enhance the growth vigor. The present study investigated the effects of the stumping height on regeneration and invigoration of seabuckthorn. Results showed that stumping height of 8cm achieved the maximum of the height of tree, canopy and branching number at the same tree-age. At the same stumping height, the best growth condition and obvious regeneration phenomenon was observed after 7-8 growing years.
