摘　　要：以菜豆为试材,连续2年研究菜豆植株所吸收的氮、磷、钾养分在菜豆植株各器官的分配模式。结果表明:菜豆植株各器官对氮磷钾养分需求量依次为氮>钾>磷;各器官对N养分需求依次为叶>嫩荚肉>嫩荚籽粒>茎;对P养分需求依次为叶>嫩荚肉>茎>嫩荚籽粒,对K养分需求依次为嫩荚肉>叶>茎>嫩荚籽粒。Taking snap bean as test material,snap bean roots uptake NPK from soil and support the organs grow,NPK distribute in leaves, stems,pods and etc. Through 2 years continuous experiment,the results showed that the uptake of N was in sequence of tender leaves〉tender pods〉fresh beans〉stems and P was in sequence of leaves〉tender pods〉 stems〉fresh beansand the uptake of K was in sequence of tender pods〉leaves〉stems〉fresh beans.
