The paper takes Breakingfruit Chinkapin fibre and other wood fiber compound manufacturing MDF's Processing-parameter for research object. Use the diagonal intersection trial law designing the trial scheme. The focal point is studied the major Processing-parameter of Breakingfruit Chinkapin with other woods to manufacture MDF. And internal bond strength, modulus of rupture, modulus of elasticity, formaldehyde emission content, thickness expansion rate of water absorbing and density of MDF are analysed. From Variance, Range and other methods seek the better Processing-parameter.
