摘　　要：通过对两种免耕直播栽培油菜播种方式进行两年的比较试验,结果表明:机沟机播较机沟撒播可增加产量81.7kg/hm2,增加产值571.9元/hm2,降低成本1875.0元/hm2,提高效益2446.9元/hm2,因此,机沟机播既能增产增收,又能节本增效,是值得推广的一种油菜机械化栽培模式。The comparative experiments of two kinds of no-tillage direct sowing modes of rape were carried out for two years.The results showed that： in comparison with the mode of mechanically-ditching manual broadcast sowing,the mode of mechanically-ditching mechanically-sowing could increase rapeseed yield and output value by 81.7 kg/hm2 and 571.9 yuan/hm2 respectively,reduce the production cost by 1875.0 yuan/hm2,and enhance the economic benefit by 2446.9 yuan/hm2.Therefore,the mode of mechanically-ditching mechanically-sowing can not only increase the yield and output value,but also save the production cost and increase the economic benefit,so it is worth to popularize this mode in rape mechanized cultivation.
