对芒市土壤进行了采样分析,并与全国第二次土壤普查历史数据进行对比,研究了芒市土壤主要养分状况。结果表明,芒市土壤有机质含量处于较高水平,平均含量为24.96 g/kg;土壤有效磷水平整体偏低,平均含量仅为16.89 mg/kg;土壤速效钾的整体水平较高,平均值为133.19 mg/kg;土壤pH值整体偏酸,平均值为5.79。与第二次土壤普查时相比,芒市土壤中的有机质水平整体下滑,趋向于中等水平;有效磷水平得到一定的提高,趋向于中等水平和缺乏水平;速效钾含量整体下滑,中等水平和缺乏水平所占比重增加;土壤有酸化的趋势,说明芒市土壤肥力整体上有降低的趋势。
The samples of Mangshi soil were sampled and analyzed and compared with the data of the second national soil census. The main nutrient status of the soil was studied. The results showed that the content of organic matter in Mangshi City was at a high level, with an average content of 24.96 g / kg. The content of available phosphorus in soil was low and the average content was only 16.89 mg / kg. The average level of available potassium in soil was higher 133.19 mg / kg. The soil pH was slightly acidic, with an average of 5.79. Compared with the second soil survey, the level of organic matter in Mangshi soil decreased as a whole as a whole, and the content of available phosphorus increased to some extent, which tended to be moderate and deficient. The content of available potassium decreased, Lack of the proportion of the increase in the level of soil acidification trend, indicating Mans soil fertility as a whole to reduce the trend.
