| Abstract: | [ Objective ] The research aimed to find out the soil nutrient status of corn growing areas in Xinping County, and guide scientific ferti- lization. [Method] Soil pH, organic matter, hydrolytic N, available P, available K, effective Mg, effective S, effective B,effectfve Mn and ef- fective Zn were analyzed of tobacco growing areas in Xinping County. [ Result] 54.48% soil was acidic. 35.69% soil organic matter was lower. 30.68% hydrolytic N, 36.5% P, 41.81% K, 35.95% S, 12.42% Mg, 84.31% B,16.99% Mn, 56.86% Zn were deficient. [Conclusion] Attention should be paid to the regulation of soil pH and the application of organic fertilizer and trace element fertilizer. |
