摘要
科学施肥是果树正常生长及生产优质果实的基础。果树营养元素的积累动态,可以反映出树体的养分需求和分配规律。综述了梨树在生长发育的各个时期体内元素的分布情况,以期为科学施肥及制定合理的栽培技术提供重要的理论依据。
Scientific fertilization is base for normal growth and qualified fruit production. Occumulation dynamics of fruit tree nutritive elements reflects the nutritive requirement and distribution law of the fruit trees. The paper summarized the inner elements distribution at each growth stage on purpose to provide theorical basis for the scientific fertilization and rational cultivation management.
