Abstract
To study the impact of different culture conditions to the growth and yield, an orthogonal experiment was conducted with four factors-sowing date, basic seedling, nitrogen rate and water depth and three levels (L934) about Mid-season Hybrid Rice Feng-liang-you-xiang-1 for 3 years (2009-2011). The results showed that: (1) the effect of the climatic conditions in different years on the growth duration and yield of mid-season rice is very significant; (2) the effect of sowing date on the growth duration and yield of mid-season rice is very significant. As the sowing date is delayed, the growth duration is shortened. (y = -0.2222x + 132.98; R = 0.9983*, y represents growth duration and x represents sowing date).When the sowing date was May 1, the yield was the highest; (3) the effect of nitrogen rate on the growth duration and yield of mid-season rice is also very significant. As the nitrogen rate increases, the growing duration and yield shows an increasing trend. The overall conclusion was that the yield was the highest when planting on May 1, with a basic seeding number of 480000/hm2, a nitrogen rate of 135 kg + 120 kg + 105 kg/hm2 and a water depth just casing the surface of field when transplanting.
