摘　　要：为了给测土配方施肥提供基础数据，对黔西县项目区的旱耕地的土壤质量进行了初步评价。黔西县旱耕地质地主要以壤土为主，土壤pH5．5～8．5，比较适宜作物生长。旱耕地营养状况：土壤肥力水平中等，总体上普遍缺氪，中度缺磷，钾较丰富，钙、镁、硫、铁含量极丰富；锰含量比较丰富，但分布不均，变异较大；铜10％调查点缺乏，锌20％左右调查点缺乏，硼80％以上调查点缺乏。The soil quality of the dry arable lands in Qianxi county was evaluated to provide the basic data for the formulation application. The results show that the most of dry arable lands belongs to loamy soil with pH 5.5-8.5 and the soil fertility is at the middle level with nitrogen deficiency overall, phosphate deficiency, rich in potassium, very rich in Ca, Ma, S and Fe, and rich in Mn with significant variation among different lands, 10% tested sites is Cu deficiency, 20% tested sites is Zn deficiency and 80% tested sites is B deficiency.
