Survey of Soil Profile in Tobacco Fields
摘要
Abstract
[Objective] The research aimed to study the changing regularity of soil physical and chemical properties and the soil fertility in tobacco field in Shizong County of Qujing City. [ Method]Soil physical and chemical properties of six soil profiles were studied. [ Result] Soil pH, content of available nitrogen, phosphorus, potassium, organic matter, bulk density, CEC, total porosity,Ca2+ and Mg2+ decreased with the deepening of the soil under the plough layer, and soil fertility decreased, the vent ability became poor. And there were positive correlation between soil pH and soil available nutrients, bulk density and CEC, so soil pH was one of the important factors who could affect soil physical and chemical properties. [Conclusion] With the increase of the soil depth,the decrease of soil fertility was more obvious, the physical and chemical properties in tobacco filed were poorer, which wasn' t beneficial for the tohacco growth.关键词
