花江峡谷地区顶坛花椒生长状况与土壤条件相关分析

以贵州花江峡谷地区特有植物顶坛花椒 (Zanthoxylum planispinumvar .dintanensis) 1] 为对象 ,根据当地特殊的“盆景农业”现象的特点 ,通过测定 1- 10龄的单株花椒的冠幅、株高、地径及其生长土壤的土量、土深、上表面积六个指标 ,对花椒组各指标与土壤组各指标进行单相关分析。结果表明 :顶坛花椒总体生长状况与其持土量 (相关系数 0 6 6 4 76 0 976 )、上表面积 (相关系数 0 5 0 819973)显著相关 ,与土壤深度 (相关系数 0 36 4 32 56 14 )成正相关关系。该项定量研究的结果对顶坛花椒的栽培技术及生态效应研究具有一定价值

Interrelated analysis between the growing state of Zanthoxylum planispinum var. dintanensisand the soil situations in the area of Huajiang vallley

The object of the study is the typical species Zanthoxylum planispinum v ar. dintanensis in Huajiang valley area of Guizhou Province. The measure ment indexes interrleated analysis between the soil situation and the growing st ate of Zanthoxylum planispinum var. dintanensis are six includin g the cap range, height, diameter of the dominant stem from 1 to 10 years, soil weight, depth and upper surface area of their growing soil. The results show tha t the general growing state of Zanthoxylum planispinum var. dintanensis with its soil weight and the upper surface area of the soil are interre lated greatly. Their interrelated coefficients are 0 664 760 976 and 0 508 199 73 respectively. The interrelated coefficient of the total growing state of Zanthoxylum planispinum var. dintanensis with the depth of the soil is positively interrelated with an interrelated coefficient of 0 364 325 614. This quantity investigation result is valuable to study the cultivation t echnology and the ecological effect of Zanthoxylum planispinum var. dint anensis.
