摘要

分析了半干旱退化山区荒山5a生沙棘×山桃混交林与山桃纯林系统的土壤养分状况。结果发现

山桃×沙棘混交林土壤有机质和氮素有明显的提高。在林木根系活动层40-60cm范围土壤有机质、氮素增量高于山桃纯林

土壤速效磷增幅较小

土壤速效钾有少量增加。

Abstract

Soils of the 5 year sea-buckthorn and mountain peach mixed forest and the mountain peach pure forest in the semiarid degenerated mountain area were analyzed.Soil organic matter and nitrogen of the mountain peach and sea-buckthorn mixed forest were distinctly increased. In the 40-60 cm active layer of the forest root system

soil organic matter and nitrogen were higher than those of the mountain peach pure forest

and the increase in available phosphorus was less

and available potassium increased a little.
