摘要
研究了云南绿春哈尼梯田不同土地利用方式下（水田、干田、旱地）土壤有机质、碱解氮、速效磷和速效钾特征。结果表明：（1）土壤有机质、碱解氮、速效磷和速效钾的含量范围水田分别为27．47～47．14g/kg、94．23～137．47mg/kg,3．68-13．31mg/kg和78．43～178．90mg/kg；干田分别为22．90～32．49g／kg、66．14—93．91mg／kg、2．20-4．55mg／kg和83．05-127．35mg/kg。旱地分别为29．10-41．92g/kg、85．95～107．95mg/kg、2．78—14．62mg/kg和59．75—112．23mg/kg。（2）同一山麓哈尼梯田不同土地利用方式土壤基本养分含量总体上表现为水田〉干田〉旱地，但经方差分析．各种养分含量在水田、干田和旱地之间并没有表现出一致的差异性。
This paper studied the characteristics of soil nutrients including organic matter, available nitrogen, available phosphorus and available potassium under different land uses （Paddy Field,dry Field,dry land） of Hani terrace in Lvchun county of Yunnan Province. The results showed that （1） in the Paddy Field, the content range of the soil organic matter,the soil available N ,the soil available P and the soil available potassium were 27.47-47.14 g/kg,94.23-137.47 mg/kg,3.68M3.31 mg/kg and 78.43-178.90 mg/kg; in the dry field, the content range were 22.90-32.49 g/kg,66.14-93.91 mg/kg,2.20-4.55 mg/kg and 83.05-127.35 mg/kg; in the dry land, the content range were 29.10-41.92 g/kg,85.95-107.95 mg/kg,2.78-14.62 mg/kg and 59.75-112.23 mg/kg.（2）The contents of soil nutrients were Paddy Field 〉 dry Field 〉 dry land under different land use in Hani terrace at the same foothill, but the contents of soil nutrients were not consistent difference under different land uses （Paddy Field ,dry Field ,dry land） by the one-way analysis of variance.
