| Abstract: | The experiment showed: (1) Mg expedited the absorption and accumulation of NO - 3-N in tobacco plants; (2) Mg supply remarkably increased the Mg content in tobacco leaves and sharply reduced K and Ca content;(3) Antagonistic action existed between Mg and P, Ca;(4) Supplying Mg enhanced K/(Ca+Mg) ratio in tobacco leaves and improved combustible quality of cigarettes. On the contrary, K/(Ca+Mg) ratio might be much lower and the quality be worse. |
