| 摘 要： | 在田间肥料试验的基础上,应用肥料效应函数,研究确定南亚热带气候条件下甘蔗最高产量及最大经济效益的施肥量,并进行施肥经济效益分析。结果表明,甘蔗最佳施氮量为337.6～351.0kg/ha;氮磷肥最佳配比为289.1～309.2,147.1～187.2kg/ha(N,P_2O_5);氮钾肥最佳配比为258.0～267.5,135.5～139.8kg/ha(N,K_2O)。在这种施肥量与配合量下,经济效益最高。

| Abstract: | On the basis of previous field fertilizer experiments, the dressing effect functions were used to study and determine the levels of fertilizer applied on sugarcane with maximum cane yield and the best economic effectiveness under south subtropical climate conditions. From the result it was suggested that the optimum level of N fertilizer applied and the optimum dosages of N, P_2O_5, and N, K_2O combined application were 337.6-351.0 kg/ha, 289.1-309.2, 147.1-187.2 (N, P_2O_5) and 258.0-267.5,135.5-139.8 (N, K_2O) kg/ha, respectively. In these levels of fertilizer applied the economic effectiveness was the best. |
