| 摘 要： | 通过对大葱不同生育期生长量及各元素含量的测定,确定大葱的阶段需肥量以及各元素在不同器官的分布。结果表明:大葱在10～11月份生长量最大,生长最为迅速;大葱对各元素的阶段需要量除氮、磷、钙3种元素外,其余8种元素均在10～11月阶段需肥量最大,除铁、锰2种元素外,其它元素均在6～7月阶段需肥量最小;P、S、Mg、Cu、Zn、Fe、Mn主要分布在大葱的根部,N、K、Ca在大葱叶中含量较多,而B则在假茎的比重较大。

| Abstract: | The fertilizer requirement at different growth stages of Welsh onion and the distribution of elements in different organs were determined through measuring the amount of growth and the contents of different elements.The results showed that the growth amount of Welsh oinon was the most and the growth speed was the highest from October to November.Except nitrogen,phosphorus and calcium,the requirement of the other eight elements was the most from October to November;expect Fe and Mn,the requirement of the other elements was the least from June to July.P,S,Mg,Cu,Zn,Fe and Mn mainly distributed in the root of Welsh Oinon,and N,K and Ca mainly distributed in leaves;B mainly distributed in pseudostem. |
