摘  要:
采用三因素三水平试验设计,研究了太行山山前平原区冬小麦进一步高产的养分限制因素及氮磷钾肥的适宜用量。结果表明,氮磷钾肥用量最高的N3P3K3处理小麦产量最高, 与低肥量处理N1P1K1相比达到了极显著水平,说明增加施肥量小麦仍有增产潜力;在高氮基础上,氮磷配施效应大于氮钾配施,高氮磷基础上增加钾肥用量可进一步提高小麦产量, 但磷素仍是最主要因子;高产麦田的磷肥适宜用量在150 kg/hm2左右,氮磷钾比的适宜范围为1:(0.5-0.55):(0.4-0.45)。

摘  要:
This paper studied the high yielding applicationh of N、P、K and the Taihang Mountain area with the three-factor and three-level experiment design. The result showed that the treatment with the most N3、P3、K3 brought the highest yield. This indicated that more fertilizer can still increase the yield. Based on the high quantity of N, the utility of P increase much yield than that of K. It can increase the yield with K based on high quantity of N and P, but phosphorus is still a most predominant factor. The high yield wheat field should be applied about P 150 kg/hm2, and the radio of N, P, K should be 1:0.5 -0.55:0.4-0.45.
