直播方式对洞庭湖区早稻—再生稻产量和经济效益的影响
Effects of Direct-Seeding modes on Yield and Economic Benefit of Early Rice-Ratooning Rice in Dongting Lake Area
摘要
Abstract
In order to clarify the effects of direct-seeding modes on yield and economic benefit of early rice-ratooning rice in the Dongting Lake rice producing area,field experiment was conducted to compare the three direct-seeding modes including artificial sowing,artificial drilling and mechanical hole direct seeding in Qianshanhong town of Hunan province in 2016.The results showed that the total yield of artificial sowing mode was the highest,and those of mechanical hole direct seeding and artificial drilling were 11.49 and 10.85 t/hm2 respectively.The trend of the early rice yield was artificial sowing ＞ mechanical hole direct seeding ＞ artificial drilling,but the difference was no significant.The trend of the rationing rice yield was mechanical hole direct seeding ＞ artificial sowing ＞ artificial drilling,but the differences among the yields and their yield components were not significant.The economic benefits of mechanical hole direct seeding was the highest,and it was 1.10 and 1.62 times of the artificial sowing and artificial drilling respectively.The input-output ratio and benefit of mechanical direct seeding were higher than those of artificial sowing and artificial drilling.Therefore,the mechanical hole direct seeding was the cultivation pattern with advantages,such as higher economic efficiency and labor saving,which have great development prospects.关键词
