苹果不同生育期水肥需求规律研究进展

Research Progress in Water and Fertilizer Demand Rule of Apple in Different Growth Stages

合理的水肥供应是苹果高产、优质的重要前提,但目前苹果生产中存在的大水漫灌、施肥过量且不平衡现象影响了苹果绿色生产和农业可持续发展。本文根据前人研究成果,对苹果不同生育期水肥需求规律进行总结分析,提出合理施用量、施用种类及施用时期,旨在为苹果科学管理提供参考。

Reasonable supply of water and fertilizer is prerequisite to high yield and good quality of apple,but flooding irrigation and excessive and unbalanced fertilization is greatly restricting apple green production and sustainable agricultural development.According to previous research results,this paper summarized the water and fertilizer demand rule of apple in different growth stages,raises reasonable application rate,types and time,aiming to provide references for scientific management of apple.
