| 摘要: |
| 田间试验中,经常需要测定许多土壤参数。确定取样数目的传统作法是盲目的,不定量的。本文论述了在确定土壤参数空间独立的前提下,如何经济合理地确定取样数目,并对计算结果的应用范围问题做了讨论。 |

| THE EFFICIENT SAMPLING FOR SOIL PARAMETERS IN A FIELD EXPERIMENTATION |
|
|
|
| Abstract: |
| The traditional method for sampling soil parameters in a field experimentation is blind and unquantitative.This paper presents briefly the basic principle and calculating procedure of the efficient sampling for soil parameters in a field experimentation,the applicable range for calculating results is discussed. |
| Key words: soil sampling semi-variogram spatial independence |
