本文根据梧州市和苍梧县现有肉桂实生林的调查材料进行分析，叶片营养元素中氮、磷、硼、铜和钙是影响桂皮产量的主要因子；微量元素铜和用是影响桂皮产量的主导因子，二者都是在高含量水平上方能获得高产。不同的叶片营养元素对各种产量的影响有所不同。 According to the investigation materials of existing cinnamon seedlings in Wuzhou City and Cangwu County, nitrogen, phosphorus, boron, copper and calcium in leaves are the main factors that affect the yield of cinnamon. Trace copper and its use affect the yield of cinnamon The dominant factor, both of which are high yields above yield levels. Different leaf nutrients have different effects on various yields.
