黄丘 一副区 山坡地占 全区面积 的９０ ％ 以上 ，大量的水 土流 失对 山坡 地的 生态 稳定 与经济 的持续发 展造成 严重影响 。针对该 地区严 酷的 自然 环境 条件， 结合 山 坡地 枣 树丰 产栽 培技术 示范基 地的建设 ，从枣树 的栽培到 枣园的 管理，研究 、分析、总 结了一 套较完善 的山坡地 枣树丰 产栽培 技术，初步 形成了 适合当地 山坡地 枣树丰产 栽培技术 体系。

The sloping land makes up more than 90 percent of the total land in the first sub zone of loess hilly region.The severe soil and water losses greatly influence the ecological stability of sloping land and the sustainable economy developmemt in this zone.Based on the local unfavorable natural environment condition and the construction of demonstration base of the cultivating techniques of high yield Chinese jujbe in the sloping land,planting Chinese jujube and the orchard management were studied.A set of detailed techniques to cultivate the Chinese jujube in sloping land has been analyzed and summarized. The technical system adaping to the management of cultivation of high yield Chinese jujube in sloping land has preliminarily formed.
