Abstract

Abstract: Three rice varieties（Fudao 99, Huaxiaxiangsi and Huanghuazhan） with four cultivation methods（manual direct seeding, aerial vehicle direct seeding, artificial seedling throwing and machine transplanted seedlings） were set to study the effects of cultivation methods on the yield and economic benefit of different rice varieties. The results showed that the theoretical and actual yield of Fudao 99 were higher than those of Huaxiaxiangsi and Huanghuazhan, which were 10 957.09 and 8 315.82 kg/hm², respectively, and it was suitable for large-scale planting in Xianning City. The yield and economic benefit of rice under aerial vehicle direct seeding and manual direct seeding cultivation methods were higher than those of artificial seedling throwing and machine transplanted seedlings, and compared to manual direct seeding, aircraft direct seeding saved time and labor. Therefore, from a light and simplified cultivation perspective, the aerial vehicle direct seeding method could be promoted in Xianning City.

Key words: rice（Oryza sativa L.）, variety, cultivation methods, yield, economic benefit
