    摘要:

    在野外调查分析的基础上,测定了不同整地方式山杏、山桃灌木林地的土壤容重、土壤有机质和速效养分。结果表明,通过人工坡地改造工程,山坡地土壤有机质和氮素有明显的提高,在林木根系活动层40—60cm土壤有机质、氮素增量高于其它处理,土壤速效磷增幅较小;土壤速效钾有少量增加。

    Abstract:

    On the basis of investigation and analysis in field,soil bulk weight,soil organic matter and quick effect nutrient were measured in apricot and peach bush forest in different rebuild ways.The result shows the content of organic matter and nitrogen are obviously increasing in hillland soil which are through artificial hillside rebuilt engineering,the incensement of organic matter and nitrogen content increasing are higher than others,but the soil quick result potassium has small increasement in forestry root active layer of 40—60 cm deepth.
