Abstract
Objective] To study nutrient situation of tobacco-planting soil in Baoji City of Shaanxi Province.[Method] The main nutrient in-dexes of 207 and 184 soil samples were analyzed to investigate variation of soil fertility between 2012 and 2015 in main tobacco-growing coun-ties of Baoji.[ Result]Available magnesium and chloride ion of soil were both at appropriate or higher level in all samples .Though organic matter of soil showed an increasing trend, nearly 60.00% of the organic matter content in soil samples was still on the low level.The propor-tions of available phosphorus and available potassium of soil at suitable level for tobacco growth had significant increase , while pH had decli-ning trend, and its overall improvement was obvious.66.30% of samples had higher alkali-hydrolyzable nitrogen, and 80.00% of available zinc in samples was at low and seriously low range .[ Conclusion] The research could provide scientific basis for improving yield and quality of tobacco in Baoji City.关键词
