摘要
2013年,对四川省会理县160份土壤样品进行主要养分含量状况评价,结果表明,会理地区植烟土壤pH有1/2处于适宜范围,其余土壤存在酸化现象。有59.38%的土样有机质含量处于丰富和很丰富的水平,大部分土壤碱解氮含量处于中等偏下水平,部分土壤的速效磷和速效钾含量处于中等偏下水平,大部分交换性镁和交换性钙含量较丰富。
Thephysicochemicalpropertiesof160soilsamplesfrommaintobacco-growingareasinHuili Countywereevaluatedin2013,the results showed that the pH value of 56.87% of the soil samples was suitable for tobacco growing, and the others were acidic. 59.38% of the soil samples had a higher level of organic matter, and 60.63% of the soil samples had a lower level of alkali hydrolysable nitrogen. And a smallpartofthe soilsamples was lack ofavailable phosphorus and potassium,while the exchangeable calciumand magnesiumcontents were rich in mostsoilsamples.
