论植物死亡

Discuss on Plant Death

植物的死亡即一株植物生命活动的终结,具有完结性和不可逆性,可分为正常死亡和非正常死亡.无论是正常死亡还是非正常死亡,都意味着生命意义的丧失,而且有其经济、社会乃至生态的属性.植物的正常死亡是植物生命活动规律的必然,而植物的非正常死亡则是有多种原因,大规模、持续性的植物非正常死亡将会给农、林业带来严重的损失,也可能会给生态、气候和环境带来极大的影响.植物非正常死亡的原因及机制探究,以及如何避免植物的非正常死亡已经成为现代生命科学、农业科学和植物医学的重要科学问题.本文论述了植物死亡的概念、死亡的判断标准、死亡的原因、死亡的过程与机制等,从避免植物非正常死亡的角度分析了植物健康管理的意义,呼吁人们积极探索避免植物非正常死亡的有效措施,把消除导致植物不健康及非正常死亡的因素、避免植物的非正常死亡当作植物医学最为重要的事业.

The death of a plant is the end of the life activities,which is terminate and irreversible,and can be divided into normal death and abnormal death.Whether it is normal death or abnormal death,it means the loss of the meaning of life,and has its economic,social and ecological attributes.The normal death of plants is the inevitable result of the law of plant life activities,while the abnormal death of plants has multiple causes.Large-scale and sustained abnormal death of plants will cause serious losses to agriculture and forestry,and may also have a great impact on ecology,climate and environment.The cause and mechanism of plant abnormal death and how to avoid it have become important scientific issues in modern life science,agricultural science and phytomedicine.This paper discusses the concept of plant death,the criteria for judging death,the cause of death,the mechanism of death and the measures to avoid abnormal death,analyzes the significance of plant health management from the perspective of avoiding abnormal death of plants,calls on people to actively explore the effective mechanism to avoid abnormal death of plants,and regards eliminating the factors that lead to unhealthy and abnormal death of plants as the most important cause of phytomedicine.
