湿地松在1973年引入本县,表现为适应性强,生长迅速,干形圆满通直,抗马尾松毛虫的能力较强,很受群众欢迎。但造林成活率很不稳定,历年来平均造林成活率在60％以下。为探索提高湿地松裸根苗造林成活率的途径,本试验分别选择阴雨天和晴天进行试验,以观察不同药剂处理的效果。试验地设在本县北部山地(大陆)和南部海岛。大陆试点海拔270～290m;东北坡上部;坡度30;土壤为石砂土;主要植被是茅草。海岛试点海拔50～80m;东南坡中部;坡度25°;土壤为黄泥沙土;主要植被是茅草和葛藤。
Slash pine introduced in the county in 1973, showing strong adaptability, rapid growth, stem-shaped perfect straight, strong resistance to dendrolimus caterpillar, very popular with the masses. However, afforestation survival rate is very unstable, the average survival rate of afforestation over the years in 60% or less. In order to explore ways to improve the survival rate of bare rooted plantation of wetland pine, the experiments were conducted on rainy days and sunny days respectively to observe the effects of different medicaments. Experimental site located in the northern mountains (mainland) and southern islands. The pilot project in the mainland is 270 ~ 290m above sea level; the upper part of the northeast slope; the slope is 30; the soil is stone sand; the main vegetation is thatch grass. Island pilot 50 ~ 80m above sea level; southeast slope of the middle; slope of 25 °; soil is yellow clay; the main vegetation is thatch and kudzu.
