| 摘 要： | 两年度在不同程度缺钾的土壤条件下，研究了钾对冬小麦生育后期某些生理特性、产量和品质的影响。结果表明，供钾能提高小麦旗叶的叶绿素含量，降低气孔阻力，提高蒸腾强度，减轻膜质过氧化程度，延迟衰老，提高籽粒灌浆速率，增加产量，改善品质。文中还讨论了高产高效的施钾量。

Effect of Potassium on Final Growth, Yield and Quality of Winter Wheat |
| |
| Abstract: | Study with winter wheat on soil laking potassium in different degree for two years revealed that application of potassium could increase chlorophyll content in the flag leaf, transpiration rate, grain filling rate and total yield of wheat, decrease stomatic risisting force and the peroxidization degree of cell membrane protein.Potassium could also delay aging of plants and improve quality of grain.To get high yield and efficiency, the applying rate of potassium is discussed. |
