浅海沉积物和花岗岩发育的砖红壤，连续种枪桉树后，有些桉树品种出现的枝梢弯曲生理病与缺乏微量元素有关，施用微肥能防止枝梢弯曲生理病的发生，或对枝梢弯曲生理病有抑制和矫正作用，从而改善桉树中长状况，提高桉树生长量，使桉树能够持续速生丰产。 Shallow sea sediments and granite brick red soil, continuous planting Eucalyptus, some eucalyptus species appear branch physiological disease and the lack of trace elements, the application of micro-fertilizer to prevent the occurrence of physiological bending of shoots, or bending of shoots Physiological disease inhibition and correction, thereby improving the long-term status of eucalyptus and improve the growth of eucalyptus, eucalyptus can continue fast-growing and high yield.
