[目的]研究钾和6-BA对苹果果实中糖和矿质元素含量的影响.[方法]于2002～2004年,分别以运城临猗县、临汾霍州和太谷果树研究所3个试验点的长富2号苹果为试材,运用不同浓度的KSO4和6-BA,采用喷施和根施相结合的方法,研究了钾和6-BA对苹果果实糖含量,以及矿质元素K、Ca、Mg、Fe、Zn含量的影响.[结果]喷施1.0％K2SO4+150 mg/L 6-BA +0.1％展着剂,可显著增加果实中的糖含量,并可提高K、Ca、Fe、Zn的含量,但对果实中Mg含量没有显著提高.[结论]为生产上采用钾和6-BA提高苹果果实品质提供了参考.%[Objective] The effect of K and 6-BA on the content of sugar and mineral element in apple fruit was studied. [ Method] The applevariety-Changfu 2 from Iinyi County of Yuncheng city, Huozhou of Linfen city and the Pomology Institute of Taigu was used as the testingmaterial in the period of 2002 -2004. The effect of the K and 6-BA, which application method was the different concentrations of K2SO4 and6-BA were sprayed and fertilized in the root of tree, on the content of sugar and mineral element including K, Ca, Mg, Fe, Mn and others inapple fruit was experimented. [ Result] The results showed that the spraying of 1.0% of K2SO4, + 6-BA of 150 mg/L + exhibition agent of0. 1% could efficiently improve the content of sugar and also the content of mineral element: K, Ca, Mg, Fe and Mn, except Mg was raised.[Conclusion] The reference for apple quality improvement through the fertilization of K and 6-BA in its production was provided.
