摘要:
为了优化冬小麦氮肥和磷肥的适宜用量，采用田间试验，研究了氮肥和磷肥施用量对冬小麦产量的影响。结果表明：氮肥的施用量与冬小麦产量的二次模拟函数为y=-0.6611x2+20.091x+234.85，相关系数为0.970 8，冬小麦产量达到最高时的氮肥施用量为228.0 kg.hm-2。磷肥的施用量与冬小麦产量的二次模拟函数为y=-0.572 6x2+13.168x+340.4，相关系数为0.921 95，冬小麦产量达到最高时的磷肥施用量为172.5 kg.hm-2。
Abstract:
In order to optimize the suitable nitrogen and phosphorus fertilizer amount of winter wheat,the effects of nitrogen and phosphorus fertilizer on yield of winter wheat were studied by field experiment.The results showed that the quadratic analogue function between nitrogen fertilizer amount and yield of winter wheat was y=-0.6611x2+20.091x+234.85，coefficient of association was 0.970 8，the amount of nitrogen fertilizer was 228.0 kg?hm-2 when yield of winter wheat was the highest; the quadratic analogue function between phosphorus fertilizer amount and yield of winter wheat was y=-0.572 6x2+13.168x+340.4,coefficient of association was 0.921 95,and the amount of phosphorus fertilizer was 172.5 kg?hm-2 when yield of winter wheat was the highest.
