Study on Status of Soil Texture and Its Relationship with Soit Nutrient in Nanping Tobacco-Growing Area
摘要
Abstract
[Objective]The research aimed to provide the basis for soil conservation and balanced fertilizer in Nanping tobacco-growing area. [ Method ] The status and evolution tendency of soil texture, and its relationship with soil nutrient were analyzed using the survey data of Nanping tobacco-growing soil. [Result] The average content of soil clay ( <0.01 mm) was 42. 15% ±7. 14%,CV was 16. 94% ,among which light and mid loam and heavy loam accounted for 65.65% and 33.51%. The soil texture had extremely significant negative correlation with total potassium,significant positive correlation with slowly available potassium,and extremely significant positive correlation with organic matter, total nitrogen,total phosphorus,alkaline hydrolytic nitrogen,available potassium,exchangeable calcium and magnesium,available sulfur,available iron,available manganese,available copper,available znic and boron. And its relationship with the contents of soil available manganese,sulfur and copper were close. The soil nutrient contents among different texture groups had significant or extremely significant differences. [ Conclusion] Most of soil texture in Nanping tobacco-growing area was moderate and its tilth was good. The content of soil clay ( <0.01 mm) showed a higher tendency for last 10 years. The appropriate addition of sand into the heavy texture soil could improve the soil texture.关键词
