Abstract:
As the main raw material for bio-ethanol and inulin industry，how to raise the tuber biological yield and quality become the focus of Helianthus tuberosus research.H.tuberosus strain ‘Red Skin’ was used as material and the effect of root cutting on the growth rate and matter accumulation rate under field condition by root cutting treatment in vegetative growth stage were studied and five root cutting radius(0,20,40，60,80 cm) were treated.The results showed that，the matter accumulation rate was improved by root cutting，and led to the tuber yield increased；it indicated first increasing and then decreasing for matter accumulation of leaf，stem and flower.And leaf matter accumulation rate was improved，which was the main reason for improving tuber yield by root cutting.Growth rate indicated first increased and then decreased under root cutting 20 cm conditions，and there was no significant effect for growth rate of other treatments and control.
