摘要
采用大田试验研究施用不同配比肥料对小麦养分吸收状况及产量影响。结果表明，小麦对Ｎ、Ｋ吸收利用以返青期为最高，对Ｐ吸收利用以开花期为最高。最佳经济施肥为每公顷施纯Ｎ∶２２５ｋｇ，Ｐ２Ｏ∶５１５０ｋｇ，Ｋ２Ｏ∶７５～１５０ｋｇ。
The effects of absorption and yield in wheat under different fertilizer have been studied.The results show: the peak of absorption andutilization in N and K is turning green; and P is booting. The best economic fertilizer per hectare is N: 225kg, P 2O 5: 150kg, K 2O: 75～150kg.
