摘要
苹果果实的外观品质是影响果园经济效益的主要因素,本文通过对1989～1995年的试验分析,揭示了红富士苹果新梢长度及8月中旬新梢中部叶片氮、磷、钾含量与果实品质问的关系,为科学施肥提供了依据;找出了解决果园郁闭问题的最佳方法及用乙烯利对红富士苹果进行疏果的时期及浓度;试制出了提高果实着色度经济有效的果实袋;为冀中南及同类型地区总结出一套提高果实外观品质的综合配套技术,通过推广应用取得了显著的经济效益。
The External quality of apple fruit is the main factor that determines the profit of an orchard. Through 1989-1995's study, the relations between the length of sticks, the N,P,k contents of leaves in mid-August and the fruit quality, were analysed. The research result provided a scientific basis for fertilizer application. Furthermore the best way of solving the problem of shading, and the suitable time and concentration of Ethrel for fruit thinning were found. Fruit bags, effective in improving fruit external color, have been developed and evaluated. As a result, a set of integrated techniques for improving the external quality of apple fruit for Middle and South Hebei has been produced. Great profit has been obtained.
