| 中文摘要: |
| 通过对安福县16个乡镇农田土壤养分调查分析,得出其养分现状。结果表明：安福县土壤pH值为5.00～5.21,偏酸性。各乡镇土壤中有机质含量、水解氮、有效磷含量范围分别为3.04～3.8%、172.66～246.72mg/kg、15.02～38.14mg/kg,根据土壤养分分级标准,均在3级以上,比较丰富,速效钾含量在48.18～139.31mg/kg范围内,属3-4级,含量较低。结合安福县土壤肥力基本状况,建议该县在农业生产过程中,注重农田合理施肥。尤其注意：通过合理耕作,增施有机肥,防止养分的侵蚀与淋失;注意平衡施肥,针对不同类型土壤应采用不同施肥方法。 |

| The status of soil nutrient in Anfu County is generalized by analyzing the conditions of the soil in 16 towns.The results show that:The range of pH value of soil in Anfu County is from 5.00 to 5.21,with a little acidity.The contents of organic matter are 3.04% ～ 3.84%,hydrolytic nitrogen are 172.66 ～ 246.72 mg/kg,and effective phosphorus are 15.02 ～ 38.14 mg/kg,which are all abundant,ranking above grade 3 according to the standard of classification of soil nutrient;the contents of quick-acting potassium are 48.18～139.31 mg/kg,ranking from grade 3 to 4.In order to prevent the loss and erosion of soil nutrient,the amounts of organic fertilizers should be increased and different fertilizer should be used according to the soil types. |
