Abstract: The Xiang Nong Da 1,one mainly cultivated cotton was selected as material,growing under various levels of light and potassium.Results showed that it had highest height in sun -shading,decreasing time lighting had no remarkable effect on height;it was significantly different,controlling under discrepant light in chlorophyll content:normal light >reduced light > sun -shading.Sun -shading,however,impacting on fresh weight of aerial part and dry weight of individual remark-ably,reduced light had no impact on two characters.There are striking differences in height,leaf square,chlorophyll content and individual dry weight under different potassium levels,and those index applying for K (+K)are higher than that in K (-K).This indicates that K is important especially for promoting seedlings construction and essential nutrition.It has no differ-ence in individual K content,K accumulation between B1A1 and B1A3;however,between B1A1 and B1A2,had significantdifference in individual K content and K accumulation.There is no difference in the efficiency of K in three light styles.
