摘　　要：于2009年对3 a生酿酒葡萄的优质品种‘左优红’在果实成熟期对树体进行解体分析。结果表明:全树营养含量为氮30.67 g,磷17.24 g,钾30.21 g,钙47.74 g,镁4.8 g,铁0.88 g。分别占树体干重的0.755%,0.410%,0.719%,1.136%,0.114%,0.021%。氮、磷在叶片中积累数多,分别为8.47、3.34 g,分别占总氮量27.26%、19.37%。主蔓中磷积累虽多,但为3 a的积累量。钾在果实中含量最高为14.28 g,占总钾量的47.26%。每生产100 kg果实当年吸收氮520.71 g,磷274.76 g,钾580.95 g,钙703.57 g,镁70.95 g,铁12.14 g,其当年吸收营养比例为10.0∶4.7∶11.1∶13.5∶1.36∶0.23。The results of dissecting analysis of ‘Zuoyouhong＇ grape during maturation period in 2009 showed that the nutrion content of a whole grape tree was, N 30. 67 g,P 17.24 g,K 30. 31 g,Ca 47. 74 g, Mg 4.8 g, Fe 0. 88 g. It accounted for 0. 755% ,0. 410% ,0. 719 %.1. 136% ,0. 114 % ,0. 021 % of dry tree weight respectively. N,P accumulation amount in leaves was the most, N 8. 47 g, P 3.34 g, it cccounted for 27.62%/0.19.37% of the total N, P content respectively, K was the most in fruit,14.28 g, accounted for 17. 26% of the total. It needed N 520. 71 g,P 274. 76 g,K 580. 95 g, Ca703. 57 g, Mg 70. 95 g, Fe 12. 14 g for 100kg fruit viekt a year. And the ration was 10. 0 ： 4. 7 ： 11.1 ： 13. 5 ： 1.36 ： 0. 23.
