栽培方式对不同品种水稻产量和经济效益的影响

Effects of cultivation methods on yield and economic benefit of different varieties of rice

采用大田试验,设置3个水稻(Oryza sativa L.)品种(福稻99、华夏香丝和黄华占)和4种栽培方式(人工直播、飞机直播、人工抛秧和机械插秧),研究了栽培方式对不同水稻品种产量和经济效益的影响。结果表明,福稻99理论产量和实际产量均比华夏香丝与黄华占高,分别为10 957.09、8 315.82 kg/hm2,适合在咸宁市大面积推广种植;飞机直播和人工直播栽培方式下水稻产量和经济效益比人工抛秧和机械插秧高,且与人工直播相比,飞机直播省时省工,因此,从轻简化栽培来看,飞机直播方式可在咸宁市推广。

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 cultiva⁃tion methods on the yield and economic benefit of different rice varieties.The results showed that the theoretical and actual yield of Fu⁃dao 99 were higher than those of Huaxiaxiangsi and Huanghuazhan,which were 10957.09 and 8315.82 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.
