山西省北部风沙区长白松引种与大苗造林试验初报
|
摘要
针对山西省北部风沙区造林和绿化中针叶树种单调的现状,开展长白松引种与大苗造林试验。结果表明,2年生裸根苗定植成活率达92.6%,大苗带母土造林成活率达98.2%,其年高生长量大于樟子松和油松,抗逆性表现优良。
Study on introduction and seedling afforestation of Pinus syluestriformis was carried out because of the present situation that the coniferous tree species of afforestation and planting in sand-blown regions in north of Shanxi was monotonous. Results showed that the survival rate of 2-year-old bare-rooted seedlings was 92. 6% and the planting survival rate of seedling with soil was 98. 2%. The annual high growth of Pinus syluestriformis was higher than that of Pinus sylvestris and Pinus tabuliformis,and its stress resistance was better.
