对MLA无性系和雷林1号两个桉树品系与厚荚相思的两种混交方式的生长、抗风力进行了研究,结果表明以按树为主要目的树种的混交林,选用的按树品系生长量必须超过与其混交的相思树种,才能获得明显的增产效应。MLA与厚荚相思带状混交能明显提高MLA无性系的生长量,以4行带效果最好,适宜在风害不严重的地区采用。MLA与厚荚相思作行间混交能降低厚荚相思的风害率并能明显增加单位面积的木材产量,在沿海台风多发地区是的推广价值的一种混交方式。
The growth and wind-resistance of two hybrids of MLA clones and two Eucalyptus strains of Leiyin 1 and Acacia crassicarpa were studied. The results showed that the mixed tree species with the main purpose of tree-based species selection were tree species growth Acacia species must be mixed with the amount of mixed species in order to obtain significant yield-increasing effect. MLA and Acacia crassicarpa can significantly increase the growth of MLA clones, with the best effect in 4 rows, which is suitable for the areas with less severe wind damage. MLA and Acacia prairie mixed can reduce the wind damage rate of Acacia crassicarpa and can obviously increase the yield of timber per unit area, which is a kind of mixed way of promoting value in the coastal typhoon-prone areas.
