摘    要:试验研究表明,甜菜各器管的相对含钾量,随生育进程呈降低趋势。叶和叶柄中的绝对含钾量呈单峰曲线变化,峰值分别出现在7月中旬和8月中旬左右。块根的绝对含钾量至状获时达到最高水平。各器管的绝对含钾量均随施钾量的增加而提高。钾对氮的吸收有促进作用,即氮与钾配合施用有利于产量的形成。

关 键 词:甜菜  钾肥  相对含钾量  绝对含钾量

Abstract:This paper showed that change of relative potassium content in sugar beet organs was a single - peak curve, which peak value appeared beet root reached the highes in the middle ten days of Jul and Aug, respectively. Absolute potassium content in sugar t in the harvest time and they improved for as much as the increase of the applies potassium quantity. There am a promoting action that potassium to absorption of nitrogen in sugar beet, namely cooperating application of nitrogen and potassium was useful to form of sugar beet output.
Keywords:sugar beet  potassium fertilizer  relative potassium content  absolute potassium content
