摘 要:
Among the 4 fine species of Salix×Jiangsuensis CL.'172',S.× Jiangsuensis CL.'194',S.×Jiangsuensis CL.'369' and S.× Jiangsuensis CL.'799' introduced from Jiangsu Forestry Academy,selected both species of S.×Jiangsuensis CL.'172' and S.× Jiangsuensis CL.'194' with good growth performance in Xiaolongshan forest area by breeding and afforestation trial.Through the analysis on growth of 7-year-old S.×Jiangsuensis forest after afforestation,the growth increment of diameter of breast height(DBH) and tree height of S.×Jiangsuensis CL.'172' are 20% and 19% higher than that of Salix caprea,whereas S.× Jiangsuensis CL.'194' are 19% and 5% higher than that of Salix caprea.So it is deemed that the growth of both selected species of S.× Jiangsuensis CL.'172' and S.× Jiangsuensis CL.'194' are better than that of Salix caprea grown in the forest area,and can extend and afforest in valley and wetland of special ecological area as fast-growth tree for restoring arbor layer.
