水稻无人机与半机械化植保对比试验

Contrast Test on Two Plant Protection Modes of Unmanned Aerial Vehicle and Semi-mechanization for Rice

植保是我国水稻全程机械化生产过程中较薄弱的环节,对水稻无人直升机植保和半机械化植保两种模式开展了对比试验。结果表明,无人机植保工作效率是半机械化作业的16倍,节省农药成本26.4%,节省单位面积总成本23.42%;同时,无人机植保还具有喷洒均匀、雾化效果好、环保效果好和安全系数高等优点。水稻无人机植保将是替代传统半机械化作业的重要模式之一。

Plant protection is a weak link in the whole mechanization of rice production in China. Contrast test on two plant protection modes of unmanned aerial vehicle（ UAV） and semi-mechanization for rice was carried out. Results showed that UAV efficiency was 16 times that of semi-mechanized operation,saved pesticide costs 26. 4% and saved total cost per unit area23. 42%. At the same time,UAV had the advantages of uniform spraying,good atomization effect,good environmental protection effect and high safety factor. UAV plant protection of rice would be one of the important models to replace traditional semimechanized operation.
