摘　　要：为了克服江西三熟制稻田季节矛盾,确保三熟制稻田的三熟高产,通过采用二晚稻田油菜谷林套播栽培方法,研究这一栽培方法对油菜生长发育及产量的影响。结果表明:与二晚接茬油菜相比,谷林套播油菜尽管个体发育受到抑制,植株比较瘦弱、总角果数、每角粒数较少、千粒重也较小,但其每公顷株数最多,在一定范围内充分发挥了群体生长优势,因而产量最高,为1680.59kg/hm2,比前者增产30.49%;每公顷的净收益也最大,为3044.95元/hm2,是前者的2.3倍。In order to overcome season contradiction of the rapeseed-early season rice-late season rice cropping system in Jiangxi Province and ensure the high yield of the mode of rapeseed-early season rice-late season rice, a field experiment was carried out to study the effect of the mode rapeseed undersowing rice on growth and yield of rapeseed under the double cropping late rice field. The results showed that, the ontogeny of rapeseed undersowing rice was inhibited, rapeseed plants were thin, the number of pod and grain per pod, 1000 grain weight were relatively smaller comparing with no-tillage direct seeding after rice harvesting, but the number of rapeseed plants per hectare was the highest in all. It could take advantage of the growth superiority and get the highest yield, （1680.59 kg/hm2）, which was 30.49% higher than the former. And it could get highest net benefit, 3044.95 yuan/hm2, which was 2.3 times than the former.
