通过大量观测资料确定了用红外测温仪观测作物冠层温差的最佳方法,并进而通过冠层温差与土壤水分之间的关系,确定了冬小麦关键期的受旱指标,为大面积应用遥感技术监测土壤水分提供了依据。
Based on a large amount of observation data, the best method of observing the temperature difference of crop canopy with infrared pyrometer was determined, and then the drought index of winter wheat in critical period was determined by the relationship between canopy temperature and soil moisture. Remote sensing Technical monitoring of soil moisture provides the basis.
