摘要
通过在沿海防护林体系设置4种立地条件进行盐桦造林试验,研究盐桦在不同立地条件下的适应生长规律,评估土壤、海风、强降雨等因素对盐桦的影响,以确定两年生盐桦适合生长的立地环境,为盐桦应用于烟台沿海防护林体系造林提供必要的理论及技术支撑。结果显示,盐桦两年生苗可以应用于沿海防护林体系,包括平原农林间作区、丘陵区、低山区,存活率均在75%以上,但在沿海基干林沙区造林效果较差。盐桦2年生苗更适合于生长在土质优良的沙壤土。盐桦受海风侵蚀容易出现不同程度枯稍现象,同时不耐长期水淹环境。
By setting up four site conditions for salt birch afforestation experiment,study salt birch under difierent site conditions to adapt to growth rules,assessment of soil,sea breeze,heavy rainfall and other factors on the influence of salt birch,to determine the biennial salt birch suitable for growth site environment,for salt birch applied in Yantai coastal shelterbelt system afiorestation to provide the necessary theoretical and technical support.ASorestation experiment proved that the two-year seedling of salt birch can be applied to the coastal shelter forest system,including plain agricultural and forestry intercropping areas,hilly areas and low mountainous areas,and the survival rate is more than 75%,but the afforestation effect is poor in the coastal basic dry forest and sand areas.The biennial seedlings of salt birch are more suitable for growing in the sandy loam with loose soil,which is prone to die slightly by sea breeze erosion,and can not withstand long-term flooding environment.
