【Abstract】 Hybrid rape-Early hybrid rice-Late hybrid rice" is a high-yielding and high-efficiency triple-cropping pattern, and its planting area was up to 60 000 hm2 within the past three years in Jianghan Plain, Hubei Province. The average yields of hybrid rape with good quality, early hybrid rice with good quality and late hybrid rice were 2.53, 7.30 and 7.91 t/hm2, respectively, and the total value of output was 30 700 RMB/hm2, 4 500 RMB/hm2 more than that of the ordinary triple-cropping pattern. The major cultural techniques for this pattern were: choosing suitable combinations and making them paired up appropriatly; seeding in proper time and making the growing season of the three crops dovetail; raising healthy seedlings and preventing them from ageing and jointing; transplanting in a properly close density; applying fertilizer and managing water properly; controlling disease and insect pests in time.
