应用地统计学和GIS空间分析技术,分析尤溪金柑主产区土壤有效硼的空间变异规律。结果表明,土壤有效硼含量范围在0.06-1.40 mg.kg-1之间,平均值为0.43 mg.kg-1;半方差函数拟合最佳模型为高斯模型,块基比值(CO/CO+C)为0.20,具有较强的空间相关性,变程为710 m;利用普通克里格法生成的空间分布图显示,研究区域有效硼含量偏低,硼含量缺乏区域和低量区域分别占总面积的5.34%和53.44%。据此,提出果园硼肥施用改进措施。

The spatial variation of Youxi kumquat orchard soil available boron was analyzed by means of GIS spatial analysis and statistics.The results showed that,soil available boron content was range from 0.06 mg·kg-1 to 1.40 mg·kg-1and average value was 0.43 mg·kg-1.The optimum semivariance function fitting model was Gaussian model,the CO/CO+C was 0.20,which indicated that it was significantly spatially dependent,the rang was 710 m.Ordinary kriging method was used to generate spatial distribution maps,which indicated the soil available boron generally presented low levels,while the 5.34% and 53.44% areas of the whole tested region were lack and low,respectively.Based on the results the improvements of boron fertilization in orchard are proposed.
