| 摘 要： | 通过钾能不同施肥量处理,研究了钾肥对冬小麦越冬性及农艺性状的影响。结果表明,随着施肥量的增加,越冬率明显提高。因此,可以通过增施钾肥提高冬小麦抗寒性,以促进其安全越冬。不同施肥量处理之间在主穗小穗数、有效小穗数、单株粒重等主要产量因素及小区产量上具有显著差异。冬小麦施用钾肥的适宜用量为75kg/hm2。

The Influence of Potassium Fertilizer on the Character of Overwintering and Agronomic Characters of Winter Wheat |
| |
| Abstract: | The effects of potassium fertilizer on the character of overwintering and agronomic characters of winter wheat were studied by using different treatments of potassium.The results showed that the rate of overwintering raised with the increase of amount of potassium applied.The cold resistance was improved and the winter wheat could overwinter safely through increase of amount of potassium applied.The differences among different treatments were significant on the spikelet number of main spike,the valid spikelet number,the seed weight of single plant and the plot yield. |
