| 摘 要： | 对辽宁省凤城市国有凤山林场苗圃不同苗龄红松苗木生长量和山地造林3龄、4龄和5龄红松苗木生长量和造林成活率进行研究,结果表明:随红松苗龄的增加,苗高、地径、主根长和大于1mm侧根条数明显增加,苗龄越长,生长量越大;山地造林采用4龄红松苗比采用3龄和5龄苗造林成活率高。

| Abstract: | Growth of Pinus koraiensis seedlings in nursery,growth rate & survival rate of 3,4 &5 year-old Pinus koraiensis seedlings planted on mountains in Fengshan City of Liaoning Province were studied.Result shows that seedling height,ground diameter,length of main root & number of lateral root which is greater than 1 mm increase evidently with the increase of seedling age of Pinus koraiensis.The longer the seedling age,the greater the growth rate;taking 4-year-old Pinus koraiensis seedlings for afforestation can obtain optimal survival rate than taking 3 or 5 year-old seedlings. |
