摘要
为明确长垣县农田土壤养分状况,2006~2011年结合国家测土配方施肥项目,对长垣县农田耕地土壤养分进行了普查,共取土样6 300个,进行了常规和微量化验,并进行了统计分析。结果表明：长垣县的土壤基本养分含量分别为有机质13.78 g/kg、全氮0.83 g/kg、有效磷15.41 mg/kg、速效钾99.61 mg/kg,pH值平均为8.47;微量元素有效锰、有效铁和有效铜的平均含量分别为14.17 mg/kg、10.01 mg/kg、1.42 mg/kg,均超过临界值,总体上处于不缺水平;有效锌平均含量为0.83 mg/kg,7.04%的土壤处于缺锌水平。长垣县耕地土壤养分总体上处于缺磷少氮,部分缺钾、缺锌状况。生产上要大力推广配方施肥,实行秸秆还田,培肥地力。
The soil nutrient of farmland in Changyuan Country was surveyed.The results showed that the average content of organic matter,total N,available P and available K was 13.78 g/kg,0.83 g/kg,15.41mg/kg and 99.61 mg/kg,respectively.The average pH value was 8.47.The average content of available Mn,Fe and Cu was 14.17mg/kg,10.01mg/kg and 1.42mg/kg,respectively,which was over the critical value.The average content of available Zn was 0.83mg/kg,and 7.04% of soil was lack of Zn.On the whole,soil was lack of P and N,parts of soil was lack of K and Zn.The formula fertilization should be extended,and the straw returning should be carried out to fertilize the soil.
