| Abstract: | An approximate calculation equation of sample number in estimation and test in forestry research and production is put forward in this paper. The value achieved by the equation is the minimum sample number needed in experiments. As a result, experimental time and cost can be decreased to the maximum degree. Meanwhile, the equation for mean value estimation fits both large sampe and small sample. |
