摘要
以 1年生南酸枣和湿地松为试验材料 ,于沿海岩质典型岸段分别就种植穴大小和磷肥蘸根、ABT生根粉沾根、选用容器苗、覆草、集团造林等共 12个技术组合进行了选择试验。结果表明 ,有利于提高湿地松造林成活率和促进幼树树高、胸径生长的技术措施分别是集团造林、选用容器苗及磷肥蘸根 ;而有利于提高南酸枣造林成活率和促进其幼树树高、胸径生长的技术措施为截干和ABT生根粉沾根处理。试验结果同时表明 ,种植穴大小对南酸枣和湿地松的成活率及其 3年生幼树生长影响不显著。
In this paper,experiments of12 afforestation techniques of Choerospondias axillaris and Pinus elliottii such as size of planting hole,staining root with ABT,container seedling afforesting,covering with stran and afforesting in plots were carried out on typical rocky coast.The results indicated that the techniques of afforestation in plots,container seedlings afforestating and staining roots with phosphate fertilizer haveimproved afforestation survival ratio,height growth and diameter growth of young Pinus elliottii,and Choerospondias axillaris have also been improved by the techniques of staining roots with ABT and cutting stem.However,the size of planting hole has little effect on the survival ratio and growth of the young trees of Pinus elliottii and Choerospondias axillaris.
