摘要
采用网格采样法采集了156个香蕉园土壤样本,用GS+对土壤养分进行半方差分析,研究养分的空间变异特征,计算土壤各养分适宜的样本容量,指出在约100hm2的研究区域内,采集54个就可以满足香蕉测土施肥的需要。
samples were collected by grid sampling in banana orchard. S pa tial variability of soil nutrients was studied according to semivariance analysi s by GS^+ software, and proper sample numbers of soil nutrients were calculated . It was pointed out that 54 samples should be gathered in the 100-hectare stud ied area to meet the demand for scientific fertilization in banana by soil test.
