| 为探究永兴县冰糖橙果园土壤肥力特征及其综合性状，为果园土壤改良和合理施肥提供依据。在永兴县冰糖橙主产区采集了284处具有代表性果园表层土壤(0-40cm)，测定了土壤有机质、pH值、全氮、碱解氮、有效磷、速效钾、缓效钾等养分指标，运用模糊综合评判法，对永兴县冰糖橙果园及其北、中和南3个区域土壤肥力质量进行了综合评价，并比较3个区域的土壤肥力差异特征。结果表明：永兴县冰糖橙果园土壤肥力为中等水平，土壤为酸性，平均仅5.47；有机质含量较丰富，为较高等水平，平均为25g/kg；土壤全氮含量为较高等水平，平均为1.86g/kg，碱解氮含量为中等水平，平均109mg/kg；有效磷平均含量25.2mg/kg，为中等水平；缓效钾含量偏低，为较低等水平，平均132mg/kg；速效钾含量处于较高等水平，平均153mg/kg。果园的3个区域土壤综合肥力属于中等偏下水平，受地形地貌、成土母质、果园管理及其他因素影响，中部区果园综合肥力高于北部和南部果园。 |

| In order to provide references for soil improvement and rational fertilization in orchard, we have to study the soil fertility characteristics and comprehensive character in Bingtang oranges orchard in Yongxing Country. We have collected 284 representative cases of orchard’s surface soil(0-40cm) from main production area in Yongxing Country. The detection indexes include organic matter, pH, total nitrogen, alkali hydrolysable nitrogen, quick-acting potassium, slow-release potassium and so on. We use fuzzy comprehensive evaluation method to evaluate the soil fertility of three areas(north area, middle area and south area) comprehensively in Bingtang oranges orchard in Yongxing Country, at the same time we compare the differences of soil fertility in those three areas. The results show that the Bingtang oranges orchard’s soil fertility at medium level and the soil was acid, the average pH value of the soil is 5.47. The soil has high content of organic material and the average value is 25g at high level. The total nitrogen in the soil at middle level and its value is 1.86g. The content of alkali hydrolyzed nitrogen at middle level and its average value is 109mg. The average value of effective phosphorus is 25.2mg and at middle level. The content of slow-release potassium is lower than average level and its value is 132mg, while the content of quick-acting potassium is at high level and the mean value is 153mg. In conclusion, the soil comprehensive fertility of those three areas in the orchard is in the below medium level. The soil comprehensive fertility of middle area is higher than north area and south area because of the topographic features, soil parent material, the orchard’s management and other factors. |
