| 摘 要： | 采集武鸣县具有代表性的土壤样品76个,以土壤养分、pH值的丰缺指标为依据,分析近20年来木薯种植地土壤养分的变化;并对不同耕作利用方式之间的土壤养分状况差异进行了分析。结果表明,当前木薯种植地的有机质、碱解氮、速效磷、速效钾等养分含量比20年前有了较大程度的提高,部分地区仍然存在着施肥不合理,速效磷、速效钾等养分过剩的问题,所调查木薯种植地也普遍存在着pH值下降的问题;不同耕作利用方式的土壤肥力质量状况依次为:木薯种植地<甘蔗种植地<木薯间作其他作物地,其中木薯间作是比较理想的耕作利用方式。

| Abstract: | According to soil nutrient,pH of plentiful lack index,76 representative soil samples were collected in Wuming to analyzed variety of soil nutrient,and the difference of the soil nutrient of different farming way was studied.The results showed that organic matter,alkali-hydrolyzable nitrogen,rapidly available phosphorus and rapidly available potassium had increased gradually over 20 years.Unbefitting fertilization and over much rapidly available phosphorus,rapidly available potassium nutrients existed still in some regions.The investigated cassava plants also widespread existed the problem of pH to be descending.The order of fertility condition with different farming types was: The cassava plants
