摘要
本文以石灰岩山区的野生连翘灌丛为对象,研究了立地条件对单株结果的影响。按单株结果量划分了4个立地类型组,确定了药用连翘林的适生范围,提出了分类经营意见.
Weeping forsythia ( Forsythia suspensa ) bushwood has a wide distribution in limestone soil in Mt Taihang. In this Paper, using quantitative theory I and cluster analysis method, we studied the relationship between the site and fruit yield per bush. The analysis showed that, altitude, soil depth and slope direction are three major factors that limit the yield their scores being 86.1% of the total in quantitative theory I. We divided the site groups into four site types according to fruit yield per bush. We also discussed the suitable site types for this medicinal crop and the management plans.
