摘要： 通过对32个有代表性果园苹果花矿质营养分析,采用平衡指数法对山东栖霞市红富士苹果进行了花样营养诊断。结果表明:红富士苹果花样N、P、K、Ca、Mg、B、Fe、Mn、Cu、Zn的适宜含量分别为(28.79±4.65)g/kg,(5.11±0.74)g/kg,(16.24±1.02)g/kg,(84.01±20.68)mg/kg,(43.54±9.46)mg/kg,(94.13±12.27)mg/kg,(109.08±38.9)mg/kg,(60.25±16.7)mg/kg,(10.09±3.15)mg/kg,(28.31±5.06)mg/kg;各营养元素的变幅表现为:Fe>Cu>Mn>Ca>Mg>Zn>N>P>B>K;花样各营养元素之间存在着增效或拮抗效应;对Fe、Mn、Cu元素需求强度较大的果园分别占供试果园的53.1%,46.9%,37.5%;所有营养元素基本都有处于正常值区和高值区,在其他区域分布较少,K则全部处于正常值区。

Abstract: Flowers samples were taken from 32 red Fuji apple orchards in Qixia Shandong Province and flower nutrition diagnosis was done using Equilibrium Index method. The results showed that the optimum concentrations of N,P,K,Ca,Mg,B,Fe,Mn,Cu,Zn in Fuji apple flowers were (28. 79 ± 4. 65) g /kg,(5. 11 ± 0. 74) g /kg,(16. 24 ± 1. 02) g /kg,(84. 01 ± 20. 68) mg /kg,(43. 54 ± 9. 46 ) mg /kg,(94. 13 ± 12. 27 ) mg /kg,(109. 08 ± 38. 9 )mg /kg,(60. 25 ± 16. 7) mg /kg,(10. 09 ± 3. 15) mg /kg,(28. 31 ± 5. 06) mg /kg,respectively; The different nutrient element change ranges Fe > Cu > Mn > Ca > Mg > Zn > N > P > B > K; and there were synergistic effects or antagonistic effects in them. The orchards with Fe,Mn and Cu deficit accounted for 53. 1 %,46. 9 % and 37. 5 % of total studied orchards,respectively. All the nutrient elements were almost in the optimum dose zone and high dose zone, less in other zones,K was completely in the optimum dose zone.
