测亩仪在农田面积测定中的精度研究

Research on Mu Meter Precision in the Determination of Farmland Area

采用不同型号的测亩仪,在阴天、雨天以及晴天等天气状况下,对地形不同、面积不同、形状不同的不同区域进行多次测量,利用比测法将测亩仪测得的面积数据与更高精度仪器测量的数据进行比较,研究测亩仪在农田面积测定中的精度。通过分析,总结出测亩仪在农田面积测定中的误差规律,为生产实践提供参考,实现农业管理精准化。

Adopting different Mu meters, in cloudy, rainy and sunny weather conditions, regions with different terrain, area and shapes were measured. Using comparative measurement method, measured data obtained by mu instrument were compared with the measured data of higher precision instrument, the precision in the determination of mu meter in farmland area was studied. Through research, the error laws of mu meter in farmland area determination were summerized, which will provide reference for production practice and realize precision agriculture management.
