胡椒养分含量状况的研究
Study on Nutrient Concentration Status of Pepper
【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.
