【摘要】 通过对湿地松在不同立地条件下的前期生长观察研究认为:湿地松在海堤的生长量虽略低于平原水稻土,但也生长良好,在土壤含盐量为的老海堤上生(含苗龄)湿地松平均树高、胸径分别达 0.34 % 9 a 3 a到和;在土壤含盐量达到的新筑海堤上也生长良好,大苗移栽成活率达,栽后 5.64 m 9.4 cm 0.5 % 100 % 3 a(含苗龄生)平均树高、胸径,是适于海堤发展的防护林或绿化树种。为提高造林成活 6 a 3.86 m 5.2 cm率,在海堤造林宜采用大苗移栽。更多还原

【Abstract】 Observations on early growth of Pinus elliottii under different site conditions showed that increment in coastal bank was a little lower than in rice field, but it grew well. The average tree height and DBH of 9-year P. elliottii (including 3-year seedling period) reached respectively 5.64 m and 9.4 cm in old coastal bank with 0.34% saline content while that of 9-year plant(including 6-year seedling period) 3.86m and 5.2cm in newly built bank with 0.5% saline content.The survival rate of the latter seedling topped 100%. To increase survival rate of fore-station, it is better to transplant with big seedlings.更多还原
