| Abstract: | In order to explore the soil fertility qualities of tobacco planting arrears in Xinwen county , we collectedSthirty soil samples which were the most representative in Xinwen county to analyze the pH value and soil nutrient contents status .The results showed that soil acidity was between acidity and neutrality ,the average pH value was 6.23. Soil organic matter was rich and the average value of it was 3.18%. The average value of total nitrogen content was 1.84 g/kg, and the average value of available nitrogen content was 164.20 mg/kg, both total nitrogen content and total nitrogen content were rich. Soil total phosphorus and available phosphorus were poor, the average value of total phosphorus was 0.89 g/kg, and the average value of available phosphorus was 17.71 mg/kg. The average value of soil total potassium content was 19.4 g/kg, and the average value of available potassium content was 17.71 mg/kg, the soil was lack of available potassium. The researching results will improve the yield and quality of tobacco by scientific farming and rational fertilizer. |
