植物医学的新概念——营养病害

Nutritional Disease——A New Concept of Phytomedicine

植物的抗性是植物健康的基本特性,而营养保障与平衡是植物抗性维护最为重要的基础,矿质营养元素对植物健康的影响是多方面的,与病害发生关系十分密切.本文提出了营养病害的概念,包括营养失衡引起的植物生理性病害--"非侵染性营养病害",以及营养失衡引发病原物侵染而导致侵染性病害发生的双因子联动"侵染性营养病害"2个方面.重点描述了侵染性营养病害的特征,分析了侵染性营养病害形成的机理,并提出了侵染性营养病害控制的对策.系统形成植物营养病害的概念,明确侵染性营养病害形成的机理,对丰富植物医学理论,推进植物医学事业的发展具有重要的参考价值.

The most dominant factor for the occurrence of plant diseases is the resistance of plants,which is closely related to the health of plants.Nutritional balance is the most important factor of plant health.This paper proposes,for the first time,the concept of"nutritional diseases".It involves"non-infectious nutritional diseases"and"infectiousnutritional diseases".The former refers toplant physiological disorders caused by nutritional imbalance,and the latter refers tothe two-factor linkage diseases caused by the pathogen infection after plants suffering the imbalance of nutrient elements.This paper focuses on the characteristics of infectious nutritional diseases,analyzesthe mechanism for their occurrence and proposespossible measures for their control.The authors argue that it is of significant reference value for enriching the theory of phytomedicine and promoting the development ofphytomedicineto form a systematic concept ofnutritional diseases and understand the mechanism of their formation.
