Abstract

In order to improve the characteristic of full aroma of flue-cured tobacco and prevent soil harden in Henan, the test took Zhongyan 100 as material, studied the effect of potassium humate on soil NPK and neutral aroma constituents of flue-cured tobacco in Yancheng. The results showed that the application of potassium humate could improve the content of NPK in soil and in favor of the generation of neutral aroma constituents of flue-cured tobacco, and disposing the fertilizing amount of conventional fertilizing+150 kg/hm2 had the best result.
