Abstract
Different treatments in the tobacco fields soil by adding different potash fertilizers were out for studying the dynamic changes and their influence on the quality of tobacco leaves.According to the result of this experiment,the content of total kalium in the soil decreased along with the uptake by tobacco plants.At different stages,the content of available potassium was humic potassium + NPhumic acides+NPKpotassium sulfate+NPnone potassium+NPNo fertilizer,which is in conformity with that in the leaves.During the different periods in the soil,the content of slow effect potassium potassium sulfate+NP humic potassium + NP humic+NPK none potassium+NPno ferfilizer.And the humic potassium manure has an obvious effect on maintaining the richness of the soil and improving the quality of the tobacco leaves.
