摘要
本文对海南岛东部和西北部两个试验点5年生加勒比松幼林生长进行分析。结果表明,变种地点间生长差异极为显著,西北部的加勒比松生长好于东部的;变种间在两地的生长排序不一,在土层深厚且较肥沃的海南岛西北部,古巴加勒比松和巴哈马加勒比松生长较好,其树高、胸径和材积生长量都超过洪都拉斯加勒比松,而在土壤相对贫瘠的东部,则以洪都拉斯加勒比松生长最好。
This paper analyzed the growth of Pinus caribaea plantations of 5-year-old at two sites in the east and northwest of Hainan Island. The experimental results showed that the growth of P. caribaea between two sites were different significantly. P. caribaea in the northwest performed better than that in the east. The growth among the three varieties of P. caribaea in two sites also performed differently. On the rich soil with thick soil layer in the northwest of Hainan Island where P. caribaea var. caribaea and P.caribaea var. bahamensis had best performance, their increments in diameter, tree height and volume were superior to P. caribaea var. hondurensis. While on relatively meager soil in the east, P. caribaea var. hondurensis grew better.
