| 摘 要： | 钾是玉米生长发育所必需的三大营养元素之一,土壤缺钾,直接妨碍玉米根系和茎叶的正常发育,影响对水分和养分的吸收及光合产物的合成和运输,使玉米抗病、抗旱、抗寒、抗倒伏等各项生理机能降低,影响玉米产量和品质的提高。

| Abstract: | Potassium is one of the three main elements which was need by maize in its growth and development.Maize roots,stalks and leaves can not grow regularly on soil insufficient of potassium.The uptake of water and nutrients are affected,and photosynthesis is lower and transportation of carbohydrate limited.So maize is susceptible to diseases,drought,cold stress and easy to lodging.As a result,yield and quality of maize are lower. |
