摘要
营养元素循环的分析结果表明 :尾叶桉 (Eucalyptusurophylla)生长迅速 ,所需N ,P ,K ,Ca和Mg等营养元素的量大 ,而本身的营养元素归还量小 ,土壤中所含有效N ,P ,K ,Ca ,Mg等元素远不能满足尾叶桉生长的需要 ,只有通过施肥才能保证其速生丰产 .
Through a research on nutrient cycling of introduced plant stand of Eucalyptus urophylla plantation,the result showed that Eucalyptus urophylla grew fast and needed a great quantity of nutrient including N,P,K,Ca,Mg,that the content of these elements in soil was far from enough to satisfy the plant's needs and the nutrient should be added by using adequate fertilization.
