对滨海风口沙地、基干林带和林带后沿进行种植材料选择试验研究结果表明:(1)木麻黄惠安_1 号无性苗、澳 C_(38)种源苗、海刀豆、厚荚相思、马占相思在风口沙地造林成活率高、抗风性及耐盐力强是沙荒风口理想的种植材料;(2)木麻黄、湿地松、厚荚相思、纹荚相思、马占相思、直干大叶相思、刚果12~# 桉在郁闭度0.3以下的基干林带下套种适应性强、生长良好;(3)木麻黄粤_(701)、厚荚相思作为基干林带更新材料造林保存率高、生长快、抗风力强,木麻黄粤_(601)无性系、刚果12~# 桉、湿地松在前沿林带弱风区更新生长较快,而在强风区枝叶易干枯、湿地松生长不良;(4)巨尾桉、火炬松、厚荚相思、马占相思、湿地松等树种在后沿沙地适应性强、生长量指标大,是林带后沿迹地更新适宜树种。
The results showed that: (1) Casuarina Huang Huian _1 asexual seedlings, Australian C_ (38) seedlings, sea cape bean, Acacia crassicarpa, Acacia mangium plantation in the tuyere sand has high survival rate, wind-resistant and salt-tolerant is the ideal planting material for the deserted shank; (2) Casuarina equisetifolia, Pinus elliottii, Acacia crassicarpa, Acacia mangium, Acacia mangium, Acacia crassicarpae and Congo 12 ~ #Eucalyptus had good adaptability and good growth under the trunkbelts of canopy density below 0.3 in canopy cover density. (3) Casuarina_ Guangdong (701) (601) clones, Congo 12 ~ # Eucalyptus and Pinus elliottii had a faster growth and rebound in the weak winds of the forested belt, while in the strong winds the branches and leaves were easy to dry and the growth of P. elliottii was poor ; (4) Tree species such as Eucalyptus grandis, Pinus taeda, Acacia crassicarpa, Acacia mangium, and Pinus elliottii have strong adaptability and large amount of growth index in the back sandy land.
