为探明枇杷树体中矿质营养积累与分布情况,对30年生的枇杷树进行树体分解,分别测定果实、叶片、1~3年生枝、多年生枝、主干、根系的N、P、K、Ca、Mg、S、Fe、Mn、Cu、Zn、B营养的含量和累积量.结果表明:(1)叶中N、P、Mg、S、Mn、Zn含量最高,分别为14.88、1.13、3.00、1.00 g·kg-1、279.70和35.35 mg·kg-1.(2)多年生枝中N、P、K、Ca、Mg、S、Mn、Cu、Zn、B累积量最大,分别为789.67、72.6、402.89、1772.74、145.04、35.54、7.58、0.67、2.88和1.55 g;主干中Fe累积量最大,为35.74 g.(3)每千克鲜重生物量中11种营养元素含量总和,主干含量最高为20.64 g·kg-1;其次为叶片,含量为20.21 g·kg-1;果实中含量最少,为2.32 g·kg-1.

Taken perennial‘dahongpao’loquat tree as material, we tested the distribution and content of N, P, K, Ca, Mg, S, Fe, Mn, Cu, Zn and B in different organs of the tree. The results were as follows. (1) Contents of N, P, Mg, S, Mn and Zn were mainly distributed in leaves, which were 14.88, 1.13, 3.00, 1.00 g·kg-1, 279.70 and 35.35 mg·kg-1, respectively. (2) Accumulation amount of N, P, K, Ca, Mg, S, Mn, Cu, Zn and B were mainly dis-tributed in perennial branches, which were 789.67, 72.6, 402.89, 1 772.74, 145.04, 35.54, 7.58, 0.67, 2.88 and 1.55 g, respectively;Fe accumulation amount in trunk reached to 35.74 g. (3) Content of total 11 nutrient elements in per kilogram biomass was 20.64 g·kg-1 in trunk (FW), 20.21 g·kg-1 in leaves (FW) and 2.32 g·kg-1 in fruits (FW).
