麻竹营养规律的研究

Nutritive Peculiarity of Bamboo

通过对儋州地区正常麻竹园叶片营养状况进行调查分析,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量存在差异,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;笋中各养分含量顺序为: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。

Nutritive characteristics of Bamboo were studied by way of investigation and analysis of bamboo leaves and bamboo shoot at different growth stages. The results showed （1） the nutrient contents of leaves varied with months; the nutrient contents of leaves were different in the bamboo shoots. （2） The size order of the nutrient contents in the 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. （3）The suitable sampling time was April
