果树营养分配基本规律与研究进展OA

The basic theory of nutrient allocation in fruit trees involves the transport and distribution of mineral nutrients and photosynthates among growth centers,reproductive organs,and storage organs,following the source-sink theory.The allocation patterns are primarily characterized by temporal dynamics and spatial distribution.This paper provides a systematic review of the fundamental theories,patterns,influencing factors,management strategies,and research progress related to nutrient allocation in fruit trees,with a focus on the impact of factors such as soil,water,climate,cultivar,and tree age.It also summarizes cutting-edge research directions of nutrient allocation,including molecular regulatory mechanisms,environmental stress responses,cultivation practices,and precision management technologies.Finally,it emphasizes that future efforts should strengthen the development and application of refined fertilization and controlled-release fertilizer technologies.
