在郴州市永兴县冰糖橙主产区选择284个代表性果园土壤,测定其主要的大量元素,分析该地区冰糖橙土壤养分丰缺状况。研究结果表明:永兴县冰糖橙土壤有机质较丰富,仅有7.75%的土壤有机质含量偏低,土壤整体为酸性,施肥时宜增施石灰等碱性肥料;土壤氮元素总体状况较好,全氮处于适量和丰富水平的占79.57%,碱解氮处于适量水平的占48.24%;土壤有效磷含量水平偏低,处于缺乏水平和极缺水平的占37.68%;土壤钾元素的含量水平偏低,缓效钾的含量水平以缺乏与极缺为主,占75.71%,速效钾含量水平处于缺乏水平的占45.07%。综合研究结果分析表明,永兴县冰糖橙土壤应该少施氮肥,多施钾肥和磷肥,补充土壤元素的不足,建...

284 representative orchard soils were selected in Yongxing County of Chenzhou City to determine the major elements in the soils, then, based on the analysis, the soil nutrient status of sugar orange was analyzed. The results showed that Bingtang orange soil in Yongxing County was rich in organic matter, only 7.75% of the soil organic matter content was low, and the soil acidity and alkalinity were acidic as a whole. Therefore, when applying fertilizer, lime and other alkaline fertilizers should be added. The total nitrogen content in soil was 79.57% at the appropriate and rich levels, the amou...
