摘要 研究结果表明:我国南方风沙化土地种植芦笋后,随着种植年限的增长、土壤熟化程度的提高,风沙化土地的肥力状况得到了显著改善.主要表现为:土壤中小于0.01mm的物理性粘粒含量提高,团粒结构得到改善,土壤持水能力和养分含量提高.芦笋可以作为南方风沙化土地改良的先锋植物. Asparagus was used as a pioneer crop for improvement of sandy soil in southern China in this paper. The experimental results indicated that after planting asparagus,the structure of sandy soil was significantly improved due to the transformation of soil particles into aggregates with advance of growing years,and its fertility was obviously enhanced,which was characterized by the augmentation of organic matter,available nutrients (nitrogen,phosphorus and potassium),and moisture capacity in the soil.\;
