摘要
内蒙古自治区是全国马铃薯主产区之一,降雨不足是限制该地区马铃薯生产的重要因子,灌溉是获得高产的首要前提。但是当地水资源十分有限,因此合理灌溉在马铃薯可持续发展中有着举足轻重的地位。对马铃薯进行非破坏性、快速、简洁的水分状况监测,并据此进行灌溉量推荐十分必要,而高光谱遥感技术就具备这一特点。为此,从光合特性、冠层温度、叶片含水量和土壤含水量角度讨论了作物水分亏缺反映与高光谱反射特征关系,综述高光谱实时诊断作物水分状况的研究进展,并从马铃薯生产实践需求提出可行性研究内容,以期为高产高效的马铃薯高光谱水分诊断及节水灌溉体系构建奠定基础。
Inner Mongolia Autonomous Region is one of the main potato producing areas in China.Rainfall is not sufficient there and irrigation is the first premise factor to obtain high yield.However,the local water resource is very limited,thus reasonable irrigation has a pivotal position in sustainable development of the potato production.Using hyper-spectral remote sensing is non-destructive,rapid and simple for crop water status monitoring and irrigation recommendation.To this end,the relationship between crop water deficit and high spectral reflectance was discussed from the aspects of photosynthetic characteristics,canopy temperature,leaf water content and soil moisture content,the study progress in hyper-spectral real-time diagnosis of crop water status was reviewed,and then some feasibility programs to potato production practice needs were proposed.These would be theoretical foundations for establishing high spectral moisture diagnostic system and water saving irrigation system of high yield and efficiency potato production.
