【摘要】 用德国进口的高科技液体肥料植物动力2003对首红、银红苹果树进行叶面喷施。结果表明,用1200倍液喷施后,首红叶片中Mn,Zn,Cu,Fe等微量元素含量与对照相比都有所增加,除Fe外差异均达显著水平;银红叶片中Mn,Zn,Cu,Fe的含量也较对照增高,Mn与Zn达显著水平。用1000倍液喷施后,首红叶片中微量元素Mn,Zn含量较对照显著提高,Cu,Fe虽未达显著水平,但也有提高;银红叶片中Mn,Cu,Zn含量较对照显著提高,Fe虽未达显著水平,但也有所提高。大量元素K,Ca,Mg在喷施植物动力2003后含量均有不同程度的提高,但差异未达显著水平。更多还原

【Abstract】 Higher scientific and technologic liquid fertilizer plant motive 2003 imported form Germany was sprayed on the leaves of Red Chief Delicious and Yinhong Apple trees in present experiment, the results indicated that: after plant motive 2003 with 1 200 fold was sprayed on the leaves, micro element content of Mn, Zn, Cu, Fe in leaves of Red Chief Delicious apple trees increased in various degrees in contrast to the control, besides Fe element, the difference were significant at 0.05 level. Micro element content of Mn, Zn, Cu, Fe in leaves of Yinhong Apple trees increased in various degree in contrast to the control, and the difference of Mn, Zn element content were significant at 0.05 level; after plant motive 2003 with 1 000 fold was sprayed on the leaves, micro element content of Mn, Zn in leaves of Red Chief Delicious apple trees increased significantly in contrast to check, Cu, Fe content increased in varying degree, but not significant. Micro element content of Mn, Zn, Cu in leaves of Yinhong Apple trees increased significantly in contrast to the control, Fe content increased, but not significant. After plant motive 2003 was sprayed on the leaves, major element content of K, Ca, Mg in leaves increased in varying degree in contrast to check, but the difference was not significant.更多还原
