摘要 本文以楚雄市为例,研究了水田、撂荒地、果园、人工针叶林、次生阔叶林、原生阔叶林等6种不同土地利用方式下紫色土土壤养分的分布状况。结果表明:各种土地利用方式下,最表层土壤的各种养分含量大多是最高的。最表层土壤养分含量排序是:有机质,果园>原生阔叶林>次生阔叶林>水田>人工针叶林>撂荒地;全氮,原生阔叶林>果园>次生阔叶林>水田>撂荒地>人工针叶林;碱解氮,原生阔叶林>果园>次生阔叶林>人工针叶林>水田>撂荒地;速效磷,果园>原生阔叶林>次生阔叶林>撂荒地>水田>人工针叶林;速效钾,原生阔叶林>次生阔叶林>果园>撂荒地>人工针叶林>水田。 The purple soil nutrient distribution of 6 different land use method was researched in Chuxiong city.The results indicated that: the nutrient content of surface soil is the highest.The sequence of surface soil nutrient content is that: Organic matter,orchard evergreen broad-leaved forest secondary broad-leaved forest paddy land artificially coniferous forest wasteland;Total nitrogen,evergreen broad-leaved forest orchard secondary broad-leaved forest paddy land wasteland artificially coniferous forest;Alkeline-N,evergreen broad-leaved forest orchard secondary broad-leaved forest artificially coniferous forest paddy land wasteland;Available P,orchardevergreen broad-leaved forest secondary broad-leaved forest wasteland paddy land artificially coniferous forest;Available K,evergreen broad-leaved forest secondary broad-leaved forest orchard wasteland artificially coniferous forest paddy land.
