摘要:
掌握土壤碱解氮变异特征是合理施肥与精准农业发展的前提，而合理采样点数量的确定是高效获取土壤碱解氮空间变异特征的基础。本研究基于江苏省沛县内约38 km2的区域中148个均匀分布的土壤采样点，分析了土壤碱解氮的空间变异特征，并通过区域随机抽样理论，计算了不同置信水平和误差等级的合理采样点数量。研究表明，沛县土壤碱解氮的平均含量为109.97 mg/kg，变异系数为0.29，其在空间分布上以中部和东南部局部地区土壤碱解氮含量较高，而东北部地区含量较缺乏；在95%置信水平上，当误差为5%和10%时的合理土壤采样点的数量分别为69个和27个；而在90%置信水平上，两误差等级所需合理采样点的数量分别为56个和20个。研究结果可为该地区土壤养分调查时高效采样方案的制定提供参考。
Abstract:
Understanding the spatial distribution characteristics of soil available nitrogen is the precondition for making agricultural and environmental policies. Determination of reasonable sample size is the base of obtaining the distribution characteristics of soil available nitrogen efficiently. On the basis of 148 soil sampling points, the spatial distribution characteristics of soil available nitrogen were analyzed, and the reasonable sample sizes were estimated by the regional random sampling theory. The results indicated that the mean soil available nitrogen content was 109.97 mg/kg, and its coefficient of variation was 0.29. The available nitrogen content was higher in the central and southeastern regions of the study area. At 95% confidence level, the reasonable sampling sizes were 69 and 27 samples, respectively, with respect to the corresponding 5% and 10% error grades. Accordingly, the sample sizes were 56 and 20, respectively, at the 90% confidence level. The research results can provide reference for making efficient sampling strategy in terms of soil nutrient survey in this region.
