摘要
通过对1994年栽植的栀子林调查发现:栀子群体产量结构呈两头小、中间大分布,且单株间差异显著;立地条件对栀子的生长有一定的影响,土层深厚,栀子营养生长旺盛,则栀子产量较高;不同树形之间除树高呈极显著差异外,其他经济指标无显著差异;不同栽植密度对栀子产量有一定的影响,中等肥力的立地条件,以1.0 m×1.2 m或1.0 m×1.5 m的栽植密度为宜。
The survey and discover was made through planted Gardenia jasminodes Ellis in 1994 that the yield structure of Gardenia jasminodes Ellis population distributed small between two sides and big between middle, and difference was significance between single plantst the site condition had a certain influence for its growth, Gardenia jasminodes Ellis grew vigorously, and had higher yield with deep soil and nutrition except for the tree height had extremely significance, other economic indicator had non obvious differencet different plant density had a certain influence to the yield of Gardenia jasminodes Ellis, the density of 1.0 m×1.2 m or 1.0 m ×1.5 m was suitable for site condition of medium fertilizer.
