南方早熟梨越夏障碍与管理应对

Oversummer obstacles and management strategies of early maturing pear in the South of China

文章从南方夏季气候环境特征与梨树的越夏需求出发,分析出早熟梨果实发育与树体越夏需求之间存在的矛盾,提出了早熟梨越夏障碍的概念。针对南方梨生长季节的气候特点,探讨通过适当的栽培措施调控果园微环境,以培育健康根系,同时控制冠层,平衡树体养分、水分吸收与消耗,从而削弱早熟梨的越夏需求,维持树体在夏季胁迫环境下较高水平的生命活动,为其果实品质与产量的实现提供保障。

This article analyzes the contradiction between the development of early maturing pear fruits and the demand for oversummering pear trees based on the characteristics of the southern summer climate environment and the demand for oversummering pear trees,and proposes the concept of oversummering obstacles for early maturing pears.Based on the climatic characteristics of the growing season of southern pears,this study explored the use of appropriate cultivation measures to regulate the orchard microenvironment,cultivate healthy root systems,and control the canopy to balance nutrient and water absorption and consumption,thereby weakening the oversummering demand for early maturing pears,maintaining a high level of life activity for pear trees in the summer stress environment,and providing guarantees for the achievement of fruit quality and yield.
