湄潭县水改旱植烟土壤养分含量状况

Analysis on Different Soil Nutrient Contents of Tobacco Fields Transformed from Paddy Fields

以湄潭县4个主要种烟乡镇为研究区域,分析了水改旱植烟土壤养分含量状况。结果表明,土壤有机质含量平均为(38.96±9.85)g/kg;全氮含量平均为(2.64±0.40)g/kg;全磷含量平均为(0.94±0.22)g/kg;全钾含量平均为(17.34±4.50)g/kg;有效氮含量平均为(73.59±25.94)mg/kg;有效磷含量平均为(26.81±9.95)mg/kg;速效钾含量平均为(97.21±35.22)mg/kg。湄潭县水改旱植烟土壤有机质、全氮、全磷及有效磷含量丰富,而全钾、速效钾及有效氮含量中等。

The results from analyzing the soil nutrient contents of tobacco fields transformed from paddy fields in four main tobacco planting villages and towns show that the average contents of soil organic matter, total nitrogen, total phosphorus, total potassium, available nitrogen, available phosphorus and active potassium are（ 38.96±9.85 ）g/kg, （2.64±0.40 ） g/kg, （0. 94±0. 22） g/kg, （17. 34±4. 50 ）g/kg, （73. 59±25. 94） mg/kg, （26. 81±9. 95） mg/kg and （97.21±35.22 ）mg/kg respectively, which indicates that the soil of tobacco fields transformed from paddy fields is rich in soil organic matter, total nitrogen, total phosphorus and available phosphorus, and is of the middle contents of total potassium, active potassium and available nitrogen.
