摘　　要：2011—2012年在国家油菜产业技术体系宜春综合试验站的两个油菜示范县(市),对优质两系杂交油菜‘赣两优5号’机沟撒播轻简化栽培高产典型田块的产量、产量结构和主要栽培措施,进行了调查分析。结果表明,‘赣两优5号’在机沟撒播轻简化栽培方式下,产量达2250kg.hm-2以上的产量结构为:角果数4500万.hm-2以上,角粒数22粒以上,千粒质量4.2g左右;主要栽培措施为:播种期10月15日以前,群体密度为30万～45万株.hm-2。The yield, yield component and cultivation measure of high yield fields of good quality two-line hybrid rape ＇ Ganliangyou 5 ＇ in the machine ditching and man-made broadcast sowing simplified mode were studied in the two demonstration counties of yichun multiple test station in the state of rape industry technology system. The result showed that the yield of ＇Ganliangyou 5 ＇ was more than 2 250 kg·hm-2, which had more than 45 million pods. hm-2, more than 22 seeds, pod-1, the quality of 1 000 seeds was 4.2 g. The main cultivation measures were that its sowing period were before October 15th,its population density were between 300 000 and 450 000 plants·hm-2.
