湿地松和加勒比松分别产于北美东南海岸、古巴、洪都拉斯等地。生于炎热多雨的海洋性气候及潮湿的土壤环境,为热带、亚热带常绿乔木速生树种,树高达三十多米,胸径近一米,是当地重要的用材及采脂树种。这两种松树早在一九三○年开始引进我省,但在解放前栽植面积小、管理差, Pinus elliottii and Caribbean pine are produced on the southeast coast of North America, Cuba and Honduras, respectively. Born in a hot and rainy maritime climate and humid soil environment, tropical and subtropical evergreen tree species of fast growing trees up to 30 meters high, nearly one meter diameter, is an important timber and resinous species. As early as 1930, these two kinds of pine trees were introduced into our province, but before the liberation, the planted area was small and the management was poor.
