Jin Zhili, Guoshun Liu, Liang Wen-xu

Abstract

The pot trials with humic acid as a portion of basic fertilizer of flue\|cured tobacco were conducted. The results showed that the physiological activity, growth vigor, activity of respiratory enzymes such as ascorbic acid oxidase and polyphenol oxidase, dry weight, volume and length of root system were effectively enhanced by application of humic acid.
