中文摘要	基于农户调查以及不同灌溉方式下典型耕地地块的试验数据,采用配对T检验、曼-惠特尼U检验等非参数统计分析方法,研究了石河子垦区不同灌溉方式对铵态氮、速效磷和速效钾等的影响。结果表明,耕层土壤铵态氮质量浓度受灌溉方式影响比较显著,表现为滴灌地块大于漫灌地块;耕层土壤中速效磷和速效钾质量浓度受灌溉方式影响不显著。不同灌溉方式下,垂直方向上,铵态氮均匀分布,而速效磷和速效钾质量浓度随深度增加而明显减少;水平方向上,土壤速效养分在滴灌条件下离散程度较高,漫灌条件下相对比较均匀。
英文摘要	Statistical analysis techniques such as Ttest and Mann-Whitney Utest were used to analyze the effects of flood irrigation and drip irrigation on the soil nutrient content and its distribution based on the household survey data and the experiment data of soil nutrient under different irrigation modes.The results showed that different irrigation modes had different impacts on ammonium nitrogen content,while the content of rapidly available phosphorus and potassium were not significantly affected by irrigation mode.In soil plough layer,the ammonium nitrogen distributed evenly in vertical direction while the content of rapidly available phosphorus and potassium decreased apparently with depth increasing and their distributions were unaffected by irrigation mode.However,in horizontal direction,the distribution of different soil fertility was significantly affected by irrigation mode,which was presented as even distribution in flood condition and discrete distribution in drip irrigation mode.
