The key technologies: the optimum sowing date was from mid-September to mid-October in rapeseed-rice（corn） double cropping system region,and from mid-October to late October in rapeseed-rice-rice triple-cropping region; seeding rate was 4. 5 kg/ha-6. 0 kg/ha; the optimum density was 450000-750000 plants per ha;150-240 kg N fertilizer,60-90 kg P2O5 fertilizer,90-135 kg K2O fertilizer and 7. 5-15 kg B fertilizer were used per ha,50% of N fertilizer and the rest of fertilizer were used as basal fertilizer; segmented harvesting was done when 70%-80% of siliques per plant was yellow and combined harvesting was done when more than 90% of siliques per plant was yellow or brown.展开更多
