| Abstract: | Sowing time,sowing norm,quantity of nitrogen and phosphoric fertilizer used,row-width and rate of additional nitrogen were regarded as variable.Systematic research was carried out on 3 a using regression design and computer techniques.Mathematic models for four single measure,mathematic cultivation models for different soil with different water capacity were established.The respective agronomic measures were proposed and demonstrated. Demonstration showed they were feasible. |
