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。
The results showed that the suitable proportion of nitrogen and potassium could significantly increase the spike number, plant height, spike length, number of grains per spike and 1000-grain weight of wheat, thus promoting the significant increase of yield. Wheat with nitrogen and potassium fertilizers increased 61.3% ~ 110.9%. Under this experimental condition, the yield of N3K2 (N 210 kg / hm2 + K2O 150 kg / hm2) was the highest, and the suitable ratio of nitrogen to potassium was 1.4:1.
