盐城沿海湿地美国白蜡树引种造林试验

Introduction and Forestation of Farinus americana on Yancheng Costal Wetland of Jiangsu Province

为改变江苏盐城沿海生态环境,促进沿海经济发展,开展了美国白蜡树引种造林试验。结果表明:美国白蜡树在土壤含盐量0.3%～0.5%的条件下,海、河堤造林成活率均达90%以上,5年生幼林(苗龄1a)年均高、径生长量分别达到1.0～1.5m和1.0～1.6cm,适宜在江苏盐城沿海湿地种植,可作为用材林、防护林、风景林的优良树种。

An experiment was conducted to introduce Farinus americana into Yancheng coastal wetland to improve the ecological environment and to promote the economic development of Yancheng, Jiangsu Province. Forestation experiment showed that under the condition of soil salt content 0.3% ～ 0.5%, the survival rate of F. americana on riverbank reached over 90%, and the annual mean increment of height and basal diameter of five-year-old young trees reached 1.0 ～ 1.5 m and 1.0 ～ 1.6 em, respectively. It is indicated that F, americana is suitable to grow in Yancheng coastal wetland, and can be used as an eminent species for timber forests, shelter forests and scenic forests.
