%X Field experiments were conducted to study the effects of different application measures of potassium fertilizer by topping on K contents and K absorption in flue-cured tobacco in Yunnan Province. The results indicate that the effect of applying K_2SO_4, KNO_3 or slow-released KCl is better than that of foliar-spraying KH_2PO_4, K_2SO_4 or KNO_3 on the improvement K content in leaves, especially in upper leaves. K content in upper leaves increases from 2.6%(CK) to 3.2%(K_2SO_4 or KNO_3).
