2012年巫山县河梁基地单元植烟土壤肥力评价

2012年对在重庆市巫山县河梁基地单元采集的100个植烟土壤样品进行了土壤肥力评价，结果表明：基地单元内土壤的有机质含量较适中，部分烟田有机质含量偏低；大部分土壤碱解氮含量偏高；有近半数的土壤速效磷含量丰富，只有少部分土壤速效磷含量较少；有26％的土壤速效钾含量偏低；37％的土壤偏酸或偏碱；水溶性氯含量均属于中等偏下的水平。此外，针对土壤养分含量状况，提出了一些相应的改良措施。...

The nutrient contents in 100 soil samples collected from the tobacco fields of Heliang base unit of Wushan county in Chongqing city were analyzed in 2012. The results indicated that the soil organic matter content was generally more moderate, while that in partial tobacco fields was lower. The content of available nitrogen in most soil samples was higher. The available phosphorus content in nearly half soil samples was rich, and only few soil samples had lower available phosphorus content. The available potassium content in 26% soil samples was lower, and 37% of soil samples were acidic or slightly alkaline. Water - soluble chlorine content was at the middle - low level. Moreover, this article presented some corresponding improving measures according to the status of soil fertility.
