Abstract: This paper standardizes the operation of rapeseed production including variety choosing, field preparation, mechanical seeding, field management, mechanical harvesting etc., to realize full mechanization of rapeseed production. 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.
