植物健康概念的商榷

植物健康是经常在植物科学尤其是植物保护领域被使用的术语,但迄今仍然没有一个明确并普遍被认可的概念。通过梳理和总结不同哲学思想下植物健康概念的探讨和争论,试图在分析现有成果的基础上,获得植物健康概念的科学内涵,同时结合中国哲学观念提出了"特定遗传基质的植物(种或品种或生物型等)生长在适宜的环境中(土壤、水分和气候),没有受到其他生物和非生物(环境)因子侵扰和伤害,各种生理功能平和或平衡的自然状态,植物的这种状态就是植物健康"的概念,明确了植物健康的动态性质及阐述了植物健康下的植物种群健康,并对依据这个概念从事农林生产进行了剖析,供大家商榷。

Discussion on the concept of plant health

Though the term'plant health'is frequently used in plant sciences especially in the field of plant protection,however,it still has no clear substantial definition that is well accepted.In this paper,we reviewed the discussions and debates on the concept of plant health.We propose the concept of the plant health based on the core thoughts of Chinese philosophy,that the plant health refers to the natural states of dynamic balance of plant physiological functions of a specific genetic plant when grow in proper environmental conditions without perturbation by other biological invasion or extreme environmental injury and stresses.This definition emphasizes the dynamic property of plant population health.We further analyzed the potential significances of the new definition for agriculture and forestry.
