Abstract

Abstract: In order to explore the effects of cost saving and efficiency increasing of different rice planting methods in Wuhan, a comparative experiment on yield and planting benefit under four light and simplified planting methods was carried out with manual direct seeding （MDS） of high-quality conventional medium indica rice variety Huanghuazhan as the control. The results showed that among four planting methods, mechanical precise-quantity hill-drop drilling （MPHD） saved labor, time and highest yield, followed the seedling mechanical broadcasting （MB）. However, it increased the labor cost in seedling raising and transportation, and the output was only 465.5 kg/hm² higher than that of unmanned aerial vehicle direct seeding （UAVDS）. Therefore, from the results of cost saving and efficiency increasing, the light and simplified cultivation mode of rice planting in Wuhan should prefer to choose MPHD or UAVDS as far as possible in the future.

Key words: rice, mechanical precise-quantity hill-drop drilling, seedling broadcasting, unmanned aerial vehicle direct-seeding, manual direct-seeding
