| 摘 要： | 用“3414”回归最优设计进行了早稻肥效试验,获得肥料效应函数方程,由此得出理论氮磷钾最佳施肥量。其中,肥料施用量N 200 kg/hm^2、P2O591 kg/hm^2和K2O 120 kg/hm^2,最佳产量8 786 kg/hm^2。综合分析不同推荐施肥方法的推荐施肥量,结合当地农业生产实际,建议氮、磷和钾肥推荐施用量分别为200 kg/hm^2、40 kg/hm^2和120 kg/hm^2。

| Abstract: | The field experiments were carried out by the'3414'optimum best regression design,equations of fertilizer response functions were obtained,and the best N,P and K fertilization quantity in the theory was educed.The optimal quantity of nitrogen,phosphorus and kalium were 200 kg/hm2,91 kg/hm2 and 120 kg/hm2 respectively,and the optimal yield was 8 786 kg/hm2.Synthetically analyzing recommended fertilization quantity in different fertilization method,combining the fact of local agricultural production,the recommended fertilization quantity of nitrogen,phosphorus and kalium were 200 kg/hm2,40 kg/hm2 and 120 kg/hm2 respectively. |
