水稻冠层温度对环境温度的响应及其调控机制

Response of Rice Canopy Temperature to Ambient Temperature and Its Regulatory Mechanism

环境温度对于水稻生产具有重要影响,冠层温度反映了水稻冠层各器官表面温度的平均值,由其热学特性及对环境的生理反应构成,与环境温度显著关联,可以表征水稻内部生理活动变化,是环境条件与作物遗传特性相联系的产物。研究水稻冠层温度的影响机理和相关调控机制,可以更好地解释水稻植株和外界环境的能量物质交换,具有很高的研究价值。本文综述了水稻冠层温度的基本特征、对环境温度的相应调控机制,并对未来的水稻冠层温度研究提出一些建议,以期更好地将冠层温度应用到水稻生长监测工作中。

Environmental temperature has an important impact on rice production.The canopy temperature reflects the average surface temperature of various organs of rice canopy,which is composed of thermal characteristics and physiological responses to the environment.Canopy temperature significantly relates to environmental temperature,represents changes in rice internal physiological activities and also connects environmental conditions and crop genetic characteristics.Studying the impact mechanism and related regulation mechanism of rice canopy temperature can better explain the energy and material exchange between rice plants and external environment,which has high research value.This paper reviewed the basic characteristics of rice canopy temperature and the corresponding regulation mechanism of environmental temperature,and put forward some suggestions for future research on rice canopy temperature to better apply canopy temperature to rice growth monitoring.
