- Abstract
[Objectives] This study was conducted to understand the relationship between soil pH and soil physical and chemical properties during tobacco planting. [Methods] Through a field experiment, the pH value of tobacco-growing soil, the contents of mineral nutrients (ammonium nitrogen, alkali-hydrolyzable nitrogen, available potassium, available phosphorus), soil bulk density and porosity were investigated. [Results] The pH value of the soil after tobacco planting increased, and the contents of ammonium nitrogen, alkali-hydrolyzable nitrogen, and available potassium were closely related to the change of pH value. The bulk density of the tobacco-planting soil decreased and the porosity increased. Planting flue-cured tobacco had certain impacts on soil pH, soil bulk density and other physical and chemical properties. [ Conclusions] This study provides a theoretical basis for the investigation of the fertilization laws in the process of tobacco planting and the selection of subsequent crops.
