Abstract
The effect of different fertilizer treatments on the content of total humic acid C and amino acids and C and N of the soil microbial of tobacco soil was studied by pot experiments.The results showed that the contents of total humic acid C were increased definitely by applying cake fertilizer.The cake fertilizer had significant effect on the amount of acidic hydrolyzable amino acids.The order of the effects of fertilization on acidic hydrolyzable amino acids was neutral amino acids(average increase of 830 μg/kg)basic amino acids(300 μg/kg) acidic amino acids(80 μg/kg)sulfur-containing amino acid.The mixture fertilizer increased C and N of the soil microbial,the increase rates were 79.88%～97.14% and 29.73%～74.96% respectively compared with only using chemical fertilizer.So the microbial N played an important role in coordinating soil N applying flue-cured tobacco.The amount of acidic hydrolyzable amino acids had the positive correlation to the microbial N.The mixture fertilizer(cake fertilizer nitrogen∶chemical fertilizer nitrogen=1∶1)treatment was better to improve the quality of tobacco leaves compared with chemical fertilizer nitrogen treatment.
