不同有机肥铺施对'阳光玫瑰/SO4'葡萄吸收根解剖结构的影响
Effects of Different Organic Fertilizers on the Anatomical Structure of Absorption Roots of'Shine Muscat/SO4'grapevine
摘要
Abstract
The root system is the foundation for growth and development of fruit trees.This study investigated the effects of different organic fertilizers on development and hydraulic characteristics of grape roots at anatomical structure level,providing theoretical support for grape cultivation in the Huai-Zhuo Basin.Four-year-old'Shine Muscat'grafted on SO4 rootstock was used as the test material.The anatomical structure of absorption roots was observed using paraffin section method,and the characteristics of xylem vessels were measured to calculate hydraulic properties.The results showed that in≤1 mm diameter class,beet residue,peat,and cow manure treatments significantly reduced periderm thickness,while only peat significantly reduced it in 1-2 mm diameter class.Except for beet residue,all treatments significantly increased xylem radius in≤1 mm diameter class,while corn straw,beet residue,and mushroom residue significantly reduced it in 1-2 mm diameter class.Peat and cow manure treatments significantly increased vessel density and area in all diameter classes and improved the root-specific hydraulic conductivity.All treatments reduced the embolism vulnerability index,with peat has the most notable effect.In the Huai-Zhuo basin,appropriately applying peat and cow manure can improve the anatomical structure of'Shine Muscat'grape absorption roots grafted on SO4 rootstock,enhancing root hydraulic performance.关键词
