Abstract:

Objective: This study aims to explore the effects of different root cutting methods and fertilization on the development of jujube tree roots, providing a research basis for the development of jujube orchard root cutting and nurturing machinery, and providing reference for the prevention and control of tree root degradation and fertilizer reduction technology. Method: Xinjiang Junzao trees were used as the research object, and an experimental method based on cylindrical spatialization was designed in a relatively limited experimental area. Five treatments and one control were set up for repeated experiments to determine the root system's rejuvenation characteristics after 6 months of experimental treatment. Result: 1) Both root cutting and fertilization were able to promote the germination of root system quantity. The root cutting treatment alone increased by 244.21% (P<0.01) compared to the control group, while the fertilization treatment alone increased by 69.82% (P<0.05) compared to the control group. 2) Cutting had a more significant effect on promoting new root germination than pulling apart, with a 119.65% increase in the number of newly germinated roots (P<0.01). The distance between new roots and the broken point by pulling treatment was 13.74 times that under cutting treatment (P<0.01). 3) Root cutting and fertilization had a synergistic effect, with the number of newly germinated roots increased by 26.57% (P<0.05) compared to root cutting alone and 156.56% (P<0.01) compared to fertilization alone. Conclusion: Different root cutting methods have different effects on root system rejuvenation, and the root cutting methods cause less mechanical damage to the roots than the pulling apart. Root cutting machinery should strive to achieve the effect of neat root cutting as much as possible. Root cutting plus fertilization is a potential technique for reducing fertilizer application, and the root cutting and nurturing machinery of jujube trees should also have the root cutting and fertilization functions.
