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.
