摘要:
为研究石榴植株中大量矿质营养元素分布与累积特性,以10年生‘大笨籽’石榴植株为试材,分别测定果实、叶、一年生枝、骨干枝、主干、侧根和须根的N、P、K、Ca、Mg和S的含量。结果表明:(1)N、P、Ca等元素在叶片中含量最高,分别为20.17、2.00和30.63 g·kg-1;K在果实中含量最高,为10.23 g·kg-1,Mg和S元素在须根中含量最高,分别为1.27和1.90 g·kg-1。(2)N在骨干枝中积累量最大,为35.03 g,所占比例为25.22%;P在侧根中积累量最大,为3.66 g,所占比例为28.80%;K在果实中积累量最大,为31.97 g,所占比例为43.70%;Ca在骨干枝中积累量最大,为27.29 g,所占比例为26.42%;Mg在叶片中积累量最大,为3.86 g,所占比例为30.65%;S在果实中积累量最大,为3.48 g,所占比例为27.01%;(3)整株每kg鲜重生物量中大量元素累积量为13.69 g,其中叶片的最高为26.35 g;其次为须根,累积量为22.47 g;果实的积累量最少为8.94 g。

Abstract:
This study was aimed at understanding the distribution and contents of mineral nutrients in different organs of pomegranate trees. We tested the distribution and the contents of N, P, K, Ca, Mg, and S in different organs of a 10-year-old ‘dabenzi’ pomegranate tree. The results were as follows. (1) The leaf contained the highest contents of N, P, and Ca at 20.17, 2.00, and 30.63 g·kg-1, respectively; the fruit contained the highest K at 10.23 g·kg-1; the fibrous roots had the highest contents of Mg and S at 1.27 g·kg-1 and 1.90 g·kg-1, respectively. (2) The amount of N, P, K, Ca, Mg, and S accumulated the most in the main branches followed by the lateral roots, the fruits, the main branches, the leaves, and the fruits at 35.03 g (25.22%), 3.66 g (28.80%), 31.97 g (43.70%), 27.29 g (26.42%), 3.86 g (30.65%), and 3.48 g (27.01%), respectively. (3) Accumulation amount of major elements in per unit biomass of the whole plant was 13.69 g·kg-1 (FW). The distribution of the accumulated elements was in a decreasing order of leaves (26.35 g·kg-1 FW), fibrous roots (22.47 g·kg-1 FW), and fruits (8.94 g·kg-1 FW).
