| 摘 要： | 不同施钾水平下甜菜各器官含钾量均随施钾水平的增加而增高。各器官相对含钾量均以苗期为最高,以后随甜菜生长发育而降低;叶片、叶柄绝对含钾量呈单峰曲线变化,最大吸收量分别在7月中旬和8月中旬。块根绝对含钾量直到收获仍有增加。

| Abstract: | Potassium content of different organ in sugarbeet is increased under different potassium level,the relative potassium content of different organ are all the highest in the seedling period and decreased in the latter growth period.The absorption of potassium content of leaf blade and petiole are a curve of single peak in whole growing period and the maximum value is in middle of July and middle of August,the potassium content of root is increasing until harvest. |

| Keywords: | sugarbeet potassium level potassium content |
