Abstract: In order to reduce mechanical damage of Cerasus humilis in harvesting，three axis size，density，strong degree and picking force of Cerasus humilis 5 were analyzed.Test results showed that average particle sizes of Cerasus humilis 5 was normally distributed.With increase of fruit maturity，strong degree would decrease.Cerasus humilis extrusion resistance was anisotropic，the resistance to compression from the top was the largest，the longitudinal was the second and transverse was minimal.Additionally，at the first phase of Cerasus humilis 5， rupture force at the top of the lateral，longitudinal and its variation coefficient were 27.0%，27.5% and 23.9%，respectively.With increase of loading velocity，average picking force fell off a downward trend，and maximum force was in 5 mmmin，the second was in 15 mmmin and the minimal was in 45 mmmin.The tensile curve regression analysis of variance of Cerasus humilis 5 showed obtained decided of coefficient were 0.995 9.Test results could provide test basis for structure parameters and working parameters of picking device for Cerasus humilis.
