摘要
黄土高原地区沙棘林地土壤的含磷量,对沙棘人工更新后代的生长有重大影响,高的土壤含磷量和低的pH值,对沙棘生长有促进作用;沙棘幼苗的生长与林地上沙棘林的年龄关系不大。因此在黄土高原地区培育沙棘人工林应重视施用磷肥。
Describes that phosphorus content of forest soils has an important effect on the growth of articificial regenerated sea buckthorn seedlings on Loess plateau. High phosphorus content and low pH-value are beneficial to the growth of sea buckthorn. No relationship was found between the growth of sea buckthorn seedlings and the age of existed sea buckthorn forest. It is advised that phosphorus fertilizer should be applied to the artificial regenerated sea buckthorn forest on Loess plateau.
