湿地松和加勒此松分别产于北美洲东南海岸(主要是美国东南部的南卡罗来纳州、佛罗里达州及路易西安那州)、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,是两种热带、亚热带速生树种。两者均为高大的常绿乔木,高达30多米,胸径近1米,是当地重要的用材及采脂树种。与原产地自然条件相比較,湿地松可在我国馬尾松自然分布稍南地区引种,加勒比松可于較热地区(如广东、广西、云南等省) 引种。1930年,广东省首先引种湿地松,1947年江西、江苏、广东等7省,較大批引种湿地松;1948年广西引种加勒比松。解放后,各地陆續引种这两种树种,經过比較認眞的培育,已初步取得較好的成績。
Pinus elliottii and Pinaceae were respectively produced on the southeastern coast of North America (mainly South Carolina, Florida and Louisiana) in the southeastern United States, Cuba and Honduras. Born in a hot and humid maritime climate and humid soil environment, are two tropical and subtropical fast-growing species. Both tall tall evergreen trees, up to 30 meters, diameter nearly 1 meter, is an important local timber and resinous species. Compared with the natural conditions of origin, the Pinus elliottii can be introduced in the slightly south of Pinus massoniana in our country. The Pinus caribaea can be introduced in the hotter areas such as Guangdong, Guangxi and Yunnan provinces. In 1930, Guangdong Province first introduced Pinus elliottii, Jiangxi, Jiangsu, Guangdong and other seven provinces in 1947, a large number of introduced Pinus tabulaeformis; Guangxi in 1948 introduced the Caribbean pine. After the liberation, these two kinds of tree species were gradually introduced from all over the country. After the cultivation of more recognition, preliminary achievements have been made.
