| 摘 要： | 以27个不同基因型的水稻品种为材料进行控制性田间试验，研究了在油菜、小麦两种茬口和低钾（K1）、中钾（K2）、高钾（K3）3种施钾水平下这些品种的经济产量的变化情况，探讨了这些品种对施钾反应的差异性，并根据这些品种对施钾反应的敏感程度进行了分类。结果表明：施钾对水稻上述指标有较大的影响，但不同基因型水稻品种经济产量对施钾反应的敏感程度存在差异，根据不同水稻品种相对经济产量对施钾反应的差异可将其分为施钾反应敏感型、钝感型和中间型3种类型。

| Abstract: | The experiment was conducted under the field condition to determine the economic yield of 27 different rice genotypes under two cropping system(rape stubble and wheat stubble) and three K levels(low,medium and high).Different responses of those different rice varieties to K levels were discussed and classified.The results show that: K application could affected the said indexes significantly.However,the sensitivities of these genotypic rice of economic yield to K vary distinctively.According to the response... |
