| 摘 要： | 胡椒大、中量元素的含量在不同树龄中有所不同，幼龄期以氮最高，其Ｎ：Ｐ２Ｏ３：Ｋ２Ｏ：Ｃａ：Ｍｇ为１：０．１５：０．５３－０．９：０．２２－０．３８：０．１５－０．３０；成年龄则以Ｋ２Ｏ最高，Ｎ：Ｐ２Ｏ３：Ｋ２Ｏ：Ｃａ：Ｍｇ为１：０．１３：１．３２：０．４４：０．１６．在不施微肥的情况下，胡椒叶片缺Ｂ、Ｍｏ、Ｚｎ．成年龄胡椒各养分含量都是从萌芽期（收获后）开始，随生育期的进展而增加，到果实成熟期下降．一株中产胡椒Ｎ、Ｐ２Ｏ５、Ｋ２Ｏ总吸收量为２８２．４ｇ，其比例为１：０．１９：０．９．

| Abstract: | The nutrition status of pepper at different age of the trees is studied in this paper. Results indicate that the concentrations of macro-nutrients and meso-nutrients are different at various stage of the trees. The highest concentration of N is at the early growth stage, and at that stage, N:P2O5:K2O:Ca:Mg is 1:0.15:0.53-0.9: 0.22-0.38: 0.15-0.30. The highest concentration of K2O is at the adult stage, and the proportion of N:P: K: Ca: Mg is 1: 0.13: 1.32:0.44: 0.16. Without the fertilization of micro-element, the leaves of pepper is deficient in B, Mo and Zn. All the nutrient concentrations in pepper are increased with the progress of growth stages from shoot stage (after harvest) to adult, but are decreased with the maturation of fruit. the total amount of N, P2P5, and K2O in a pepper plant of mid-yield is 282.4g, and the nutrients proportion is 1: 0.19: 0.9. |
