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

Abstract

Abstract:

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.

Key words: high temperature, waterlogging, abiotic stress, oversummering obstacles, early maturing pear
