曲靖市植烟土壤有效锌含量状况及与土壤因素的关系分析
Distribution of available zinc and its relationship with soil characteristics in Qujing tobacco growing areas
摘要
Abstract
Available zinc, soil texture and mechanical composition, altitude, pH value, organic matter content were determined in order to describe their distribution and identify their relationships in Qujing tobacco growing areas. Results indicated that: (1) Available zinc content in soil was relatively high, which ranged from 0.05 to 194.19 mg/kg, with mean at 4.37＋8.45 mg/kg and coefficient of variation as high as 193.09%. Only a small part of tobacco growing fields showed an absence of that. (2) Available zinc content increased with higher altitude and more organic matter, and showed a parabolic trend with increase of clay particle content and higher soil pH value. (3)The order of available zinc in different agrotypes is that red earth followed by alluvial soil, paddy soil, limestone soil, yellow earth and acid purple soil.关键词
