Abstract: Xinjiang’s unique geographical conditions make the jujube quickly promoted. About 700 000 t of residual branches are produced by pruning jujube trees in southern xinjiang every year. In order to meet the demand of diversified utilization after crushing, the mechanical properties（mechanical parameters of compression, bending and shearing） and physical properties（density and water content） of the residual branches of jujube were determined. The experimental results show that the constitutive relation of the elastic section of the stress-strain curve of the residual branch of jujube conforms to hooke’s law. The anti-damage strength, anti-damage modulus of elasticity and the bearing work of horizontal grain compression were all greater than that of horizontal grain compression. There was a polynomial positive correlation between horizontal grain compression work and compressive strength, and an exponential positive correlation between horizontal grain compression work and compressive strength. The density of jujube was positively correlated with the flexural strength and shear strength, the moisture content was negatively correlated with the flexural strength, and the shear strength was negatively correlated with the power function.
