| Abstract: | Taking Jinyou 463 as tested early rice varieties to research different ratios between base fertilizer and dressing. The results showed that the treatment with base fertilizer and dressing in a ratio of 6∶4 met the normal requirements of rice growth and development, promoted the healthy growth of rice, showed better overall and economic advantages. Under this ratio, the production and value of Jinyou 463 respectively reached 7 272 kg/hm2 and 14397 yuan /hm2(RMB), output to input in a ratio of 1∶2.51. That ratio was the best in local actual early rice production. |
