Abstract:
Taking‘Lu cucumber No.3’cucumber variety as material，the effect of soluble chitosan in different methods of seed soaking and leaf spraying on cucumber seedling’s growth were studied by the method of orthogonal experiment design.The results showed that different concentrations of soluble chitosan，could promote root coordinational growth，increase the root absorbing area of cucumber seeding，enhance nutrients absorption ability；in the meantime，it enhenced chlorophyll content,soluble protein content,soluble sugar content，promoted the growth of the seeding，and finally improved the quality of cucumber seeding.Contrast with the control，A4B3(0.3 mg/mL seed soaking+1.0 mg/mL leaf spraying) was the best in plant height，stem diamete，the total volume of roots.A4B2 was the second(0.3 mg/mL seed soaking+0.5 mg/mL leaf spraying)，seedling plant height，stem diameter，total root surface area were the best，the contents of soluble protein and soluble sugar were the highest.In conclusion，the most proper concentration was seed soaking 0.3 mg/mL, leaf spraying between 0.5-1.0 mg/mL.
