热成像在荆条灌丛和栓皮栎幼苗体温测定中的应用
Application of Thermal Imaging in Measuring Temperature of Vitex negundo var.heterophylla and Quercus variablis Seedlings
摘要
Abstract
Thermal imager can measure surface temperature of matters accurately,it provides a new method for agricultural and forestry research.Temperatures of Vitex negundo var.heterophylla community and Quercus variablis seedling leaves were measured by thermal imager to provide examples of the application of thermal imaging technique in agriculture and forestry.The results showed 1) before applying thermal imager to measuring temperature of plants,the radiation emission rate of plant organs had to be determined.2) The result of the temperature measurement of Q.variablis by using thermal couple was quite similar to that by thermal imager,indicating that the later was suitable for measuring leaf temperature of plants.3) Thermal imager could be used to measure canopy temperature of plant community and leaf surface temperature of the canopy,but the air temperature of the canopy had to be measured by using thermal couple or thermistor temperature instruments.4) Thermal imager could be used to analyze the isotherm of V.negundo var.heterophylla community canopy,and to show its temperature distribution feature.The results would provide not only a method of studying nurse effects of V.negundo var.heterophylla canopy to Q.variablis seedlings,but also a method of measuring other agricultural and forestry plants.关键词
