To study the influence 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 early rice Liangyou 9168 in Jingzhou for 3 years. The results indicated that: (1) Sowing date showed significant effect on growth period, there was a linear negative correlation between sowing date and growth period (y = -0.685x + 127.54, R = 0.9986**). (2) Sowing date and nitrogen rate showed a highly significant effect on yield, the early rice yield of sowing on March 20 was the highest in the experimental range, there was a linear positive correlation between nitrogen rate and yield (y = 0.5963x + 393.43, R = 0.9709**). (3) The best combination of cultural factors for early rice was treatment 5 of sowing on March 19, basic seedling for 67.5×104 kg/hm2, nitrogen amount of 93.58 kg/hm2 and field water just covering mud.
Key words: Basic seedling, early rice, field water, nitrogen rate, sowing date, ,
