摘要
为加快油菜轻简化栽培技术的推广,开展油菜播种器播种、旋耕机播、旋耕人播、育苗移栽4种播种方式的对比试验,以探索不同的播种方式对四川丘陵区油菜生长发育及产量的影响。结果表明,4种播种方式中育苗移栽油菜苗期的生长发育各项指标均显著优于其他播种方式,而最终产量以旋耕机播最高,为2 451.0 kg·hm^(-2),其次是播种器播种,为2 289.0 kg·hm^(-2)。因此,建议丘陵区田块较大的区域使用旋耕机播的方式,而田块较小的区域则使用播种器播种。
In order to speed up the promotion of light and simple cultivation techniques of rapeseed,four kinds of seeding methods including rape seeder sowing,rotary tillage mechanical sowing,rotary tillage people sowing,seedling transplantation were compared to explore the influence of different sowing methods on the growth,development,and yield of rapeseed in Sichuan hilly region.The results showed that the indicators of growth and development of seedling transplantation during seedling stage were significantly better than the other sowing methods.However,the rotary tillage mechanical sowing had the highest final yield which was 2 451.0 kg·hm-2,and then was rape seeder sowing(2 289.0 kg·hm-2).Therefore,in the hilly area,the rotary tillage mechanical sowing method was recommended at the larger area,while the seeder sowing method was used at the smaller area.
