| 摘 要： | 试验结果表明:适宜的氮、钾用量配比可显著提高小麦的穗数、株高、穗长、穗粒数和千粒重,从而促进产量的显著提高。配施氮钾肥的小麦增产61.3%~110.9%。该试验条件下,以处理N3K2(N 210 kg/hm2+K2O 150 kg/hm2)产量最高,适宜的氮钾比为1.4∶1。

| Abstract: | The results of potted experiments indicated that combined application of N and K at an appropriate rate could improve wheat grain yield significantly by 61.3%～110.9% due to notable enhancement of spike number of wheat,plant height,spike length.grains per spike and 1000-grain weight.Under the experimental condition,at the N fertilizer usage of 1.4 g/pot and K fertilizer usage of 1.0 g/pot(N∶K=1.4∶1),wheat accessed to maximum yield.There was significant positive interaction between N and K on wheat grain yield. |
