生物的“保护反应”(中国科学院土壤研究所《土壤与作物的营养诊断》,1975)是有生命的生物在非正常环境条件下,能够自己作出适当的反应,主动地进行调整,来适应新的环境条件,以保护本身并繁殖后代的本能.而已死的、新陈代谢消失了的生物和无生命的非生物则没有这种本能.水稻毫不例外,也有这种本能.水稻的保护反应,在稻株缺乏营养元素的化学诊断上,在田间观察和判别苗情上,以及在生育期间的水肥管理方面,都可作为一种依据,它有助于我们对水稻在各个生育阶段更恰当地采取技术措施,以减少我们田间管理上的盲目性.
Biological “Conservation Response” (Institute of Soil Science, Chinese Academy of Sciences, “Soil and Crop Nutrition Diagnostics”, 1975) is a Living Creature that, under abnormal environmental conditions, is able to make the appropriate response on its own and is proactively adjusted to accommodate new Environmental conditions in order to protect itself and reproduce the instinct of offspring, while dead, metabolically lost creatures and inanimate non-living creatures have no such instincts. "Rice is no exception but also has such instincts. It can be used as a basis for the chemical diagnosis of the lack of nutrient elements in rice plants, in field observation and discrimination of seedlings, and in the management of water and fertilizer during the growing period, which helps us to take a more appropriate approach to the rice growth stage Technical measures to reduce the blindness in our field management.
