摘要
为探索庐江地区不同栽培方式对油菜产量与经济效益的影响,在相同茬口条件下,以陕油28为试验材料,研究人工育苗移栽、联合机条播和无人机撒播这3种栽培方式对油菜生育特性、产量构成因素及经济效益等的影响。结果表明,3种栽培方式同时播种,出苗基本一致,但抽薹期、初花期、盛花期和终花期人工育苗移栽较联合机条播和无人机撒播推迟7~15 d,成熟期推迟5~7 d,全生育期亦延长6~8 d。人工育苗移栽油菜产量最高,联合机条播经济效益最好,亦是目前农户主要栽培方式。
In order to explore the effects of different cultivation methods on yield and economic benefits of rapeseed in Lujiang region,Shanyou 28 was used as the experimental material under the same stubble conditions to study the effects of three cultivation methods,such as artificial seedling raising and transplanting(T_(1)),mechanized drilling(T_(2)),and drone aerial seeding(T_(3)),on the growth characteristics,yield composition,and economic benefits of rapeseed.The results showed that the seeding time of three cultivation methods was the same,the emergence of seedlings was basically the same.The bolting stage,early blooming stage,blooming stage and final flowering stage of T_(1)were delayed by 7-15 days compared with T_(2)and T_(3),the maturity stage of T_(1)was delayed by 5-7 days,and the entire growth period was also extended by 6-8 days.The yield of T_(1)was the highest,and the economic benefit of T_(2)was the best,and the mechanized drilling was the dominant cultivation method for farmers at present.
