Abstract

[Objective]The research aimed to find out the soil nutrient status of tobacco growing areas in Xinping County,and to guide scientific fertilization. [Method]Soil pH,organic matter,hydrolytic N,available P,available K,effective Mg,effective S,effective B,effective Zn of tobacco growing areas in Xinping County were analyzed. [Result] 60. 1% soil was acidic. 42. 55% soil organic matter was lower.38. 01% soil alkali hydrolytic N,36. 11% soil P,19. 06% soil K,36. 7% S,6. 38% Mg,83. 51% soil B,17. 02% soil Mn,60. 11% Zn were deficient.[Conclusion] Attention should be paid to the regulation of soil pH,and the application of organic fertilizer and micro fertilizer.
