苹果园科学施肥的理论与技术基础

The Theoretical and Technical Basis of Scientific Fertilization in Apple Orchard

阐述了土壤的四大功能及农业肥料的发展历史,为果农认识肥料及正确选择肥料普及了相关知识。对大量研究结果进行汇总,提供了各主产区红富士树叶中矿质元素含量“标准值范围”制订参考值及苹果树生理周期内水分,总养分、钾、磷、根部生长变化曲线图,为果农优化施肥提供了参考与依据。并提出在选、配肥时,要与当地测土技术相结合,配施营养全面、均衡的肥料。

The four functions of soil and the development history of agricultural fertilizer were expounded, and the relevant knowledge and the correct selection of fertilizer for fruit farmers were popularized. The standard value range of mineral element content of Fuji apple leaves in main producing areas and the growth charts of water, total nutrients, phosphorus and potassium in the physiological cycle of apple trees were provided, which provided a reference and basis for fruit farmers to optimize fertilizer application. It is suggested that the fertilizer should be combined with the local soil testing techniques, and the fertilizer should be applied with comprehensive nutrition.
