摘要: 内蒙古兴安盟突泉县、扎赉特旗于2016年各安装一套农业气象自动观测系统开展春玉米、水稻发育期、植株密度、植株冠层高度、生长状况、叶面积指数和干物质重量农业气象要素自动与人工观测对比试验。通过2016至2018年的对比试验数据分析,结果表明:作物生长状况、发育期自动观测数据与人工观测数据基本一致,完全可以代替人工观测。植株密度、冠层高度、叶面积指数、干物质重量自动观测误差相对较大,不能代替人工观测。农业气象观测要素作物生长状况、发育期的自动化、数字化观测,增强了观测资料的客观性、时效性和连续性,为提高农业气象服务准确性提供了数据支撑。

Abstract: We installed a set of agrometeorological automatic observation system in Tuquan and Zhalaiteqi respectively, Xingan league, Inner Mongolia in 2016, to perform comparison tests on automatic and manual observation of agrometeorological elements of spring maize and rice on their development period, plant density, plant canopy height, growth status, leaf area index and dry matter weight. According to the comparative test data analysis, the results showed that: the automatic observation data of crop growth status and growth period were basically consistent with the manual observation data and could completely replace the manual observation; automatic observation had relatively large errors on plant density, canopy height, leaf area index and dry matter weight, and could not replace manual observation. The automatic and digital agrometeorological observation of crop growth status and growth stage could enhance the objectivity, timeliness and continuity of observation data and provide data support for improving the accuracy of agrometeorological service.
