| Abstract: | The relationship between the main cultivation measurment and yields and benefits of Pudamai 7 were studied in this paper, through experiment designed by the orthogonal rotation regression method of 5 factors. Through analysing the established mathematical model of yield and benefit, the key factors influencing the yield and benefit of Pudamai 7 were clarified and the agronomic practices to achieve high yield and benefit were defined. This model could make sure that the yield reach 300- 350 kg/666.7m^2, the benefit exceed 385 yuan, while the optimum comprehensive practices were used and the following indices of the primary seedlings 149 200-1 612 000 plants/666.7m^2 N 16.19-17.04 kg/666.7m^2 including the subsoil N 58. 1% - 61.3% ; P2O5 3.43- 4. 10 kg/666.7m^2 ; K2O 6.67 - 7.75 kg/666.7m^2 were applied. |
