摘要
为加强铅笔工业原料林定向培育树种选择和抚育管理,通过对不同立地条件下64号杨、大叶钻天杨的栽培特性、生长节律进行了观测分析。结果表明:大叶钻天杨和64号杨可在伊犁河谷作为铅笔材进行推广种植。每年的5-6月是树高、胸径生长的最快时期,期间应加强肥水管理,促进树体生长。
In order to strengthen the tree species selection and tending management of pencil industrial raw material forest,cultivation techniques and growth rhythm about the two poplar varieties of 64 Yang and Large Zuantianyang in the different area were observed and analyzed.The results showed that 64 Yang and Large Zuantianyang were suitable as pencil wood and should.They were vigorously promoted planting in the Yili River Valley.The growth peak of tree height and stem was from May to June.Fertilizer management should conducted to advance seedling growth in the period.It could provide for species selection and management of the pencil industrial raw material forest in the future.
