通过油菜与晚稻共生播种期与播种量试验,及晚稻收割后留稻草和不留稻草试验,探索“稻-稻-油”三熟制生态区域稻油共生期与播种量,以及晚稻收割后留稻草对油菜产量的影响。结果表明:晚稻与油菜共生期1、3、5 d均可,播种量为0.50 kg/667 m~2产量较高,晚稻收割后留稻草对油菜产量影响不大。
The symbiotic sowing date and sowing experiment of rapeseed and late rice and the experiment of leaving rice after straw harvesting and no straw stay after late rapeseed were conducted to explore the rice-oil intergrowth and seeding rate and the harvesting of late rice in “rice-rice-oil” The effect of straw after leaving on rapeseed output. The results showed that the late rice and rapeseed could be symbiosed at 1, 3 and 5 d, the sowing rate was 0.50 kg / 667 m ~ 2 and the yield of late rape after harvesting had little effect on the yield of rape.
