在相同钾水平下 ,不同小麦基因型植株含氮、磷量差异显著。在低钾或缺钾条件下 ,7个小麦基因型间植株N/K比差异显著 ,P/K比差异不大。在供钾充足条件下 ,不同小麦基因型植株N/K ,P/K比不存在显著差异。从而可以看出不同小麦基因型耐低钾及高效利用钾的能力与植株氮的吸收、氮钾平衡有关 Under the same potassium level, the nitrogen and phosphorus contents of different wheat genotypes were significantly different. Under the conditions of low potassium or potassium deficiency, the N / K ratios of seven wheat genotypes were significantly different, while the P / K ratio was not significantly different. Under adequate potassium supply, N / K and P / K ratios of different wheat genotypes were not significantly different. Thus it can be seen that the ability of different wheat genotypes to tolerate low potassium and efficiently utilize potassium is related to nitrogen absorption and nitrogen and potassium balance
