Abstract: In this paper on the impact of rice production of hybrid rice varieties yield potential of their main factors using five measures: ① disc seedling, low leaf transplanting seedlings longs for big panicles; ② by organic fertilizer to ensure healthy balance growth; ③ strictly control medium-term population, increasing ear rate ④ application of ear and grain fertilizer, optimizing the allocation of canopy leaves; ⑤ pest control to ensure that live and mature, increase seed weight and seed-setting rate. So that hybrid rice panicle reached 3000000 / hm2 around, full grains reached 180-210 per panicle, spikelets reach 200-230 per panicle, stabilizing setting rate at 80-90 per cent, an effective solution to the contradictions of base ,source, flow with adequate panicle number and large panicles, and the realization of yield and quality objectives of 1200 kg / hm2.
