【摘要】 本文通过对儋州市正常麻竹园的土壤和叶片营养状况进行调查和分析,研究正常麻竹的营养特性和营养诊断方法。其结果表明:(1)麻竹叶片大中量元素养分含量都存在月份间的不同变化和差异。(2)麻竹叶片养分含量和竹笋的养分含存在差异,叶片中各养分含量从大到小排列为:N>K>Ca>S>P>Mg>Fe>Mn>Zn>B>Cu ; 而竹笋中各养分需求量顺序为:K>N>P>Ca>Mg>S>Fe>Zn>Mn>Cu>B。(3)初步确定麻竹叶片诊断的适宜采样时间为4 月份,　适宜的采样部位为下部成熟叶片。更多还原

【Abstract】 Bamboo nutritive law was study by way of investigation and analysis of nutritional status of the soils in normal bamboo plantations and leaves of crops .the nutrient contents in the leaves varied with months of the year. the nutrient contents in the leaves were different in the bamboo shoots. The size order of the nutrient contents in the le leaves were N>K>Ca>S>P>Mg>Fe>Mn>Zn>B>Cu , The size order of the nutrient contents in the shoots were K>N>P>Ca>Mg>S>Fe>Zn>Mn>Cu>B. The moderate sampling time and sampling part were April and low leaves更多还原
