Abstract
Objective] To research the effects of different potassium application types on the potassium content,etc of tobacco leaves, and to enhance the potassium content of tobacco leaves.[ Method] Three treatments of K2 SO4 were designed.Random block design was adopted. Three repetitions were designed for each treatment with in all nine plots.Other farm operation was carried out according to the conventional method.Under the same potassium application amount, we researched the potassium application mode for the effective enhancement of potassi-um content in tobacco leaves.[ Result] Under a given amount of potassium sulphate application, different application methods had certain effects on leaf area.Split application enhanced the potassium content in middle and lower leaves, but still did not enhance the potassium con-tent in upper leaves.[ Conclusion] Combination of 70% potassium sulfate as base fertilizer and 30% as topdressing has the highest enhance-ment in potassium content in tobacco leaves.关键词
