摘要	Objective: In this study, the effects of different irrigation quantity on the branching pattern and adaptability of biennial triploid Populus tomentosa plantation were investigated, in orderto provide theoretical basis for canopy management of triploid P. tomentosa plantation. Method: The branching patterns of 9 trees in a two-year-old triploid P. tomentosa plantation were measured under the sufficient drip irrigation, deficit drip irrigation and no irrigation treatment (CK). Result: The results showed that: 1) the average branch length and branching angle of the first-order branches of P. tomentosa were significantly affected by different irrigation quantity (P 0.05). Under the conditions of sufficient drip irrigation, there were more new branches in the current year, and less new branches in CK treatment. Conclusion: In summary, the twig length, branching angle and branch diameter ratio of two-year-old P. tomentosa have strong plasticity and variability under different irrigation condition. When the soil moisture is sufficient, the number of branches of P. tomentosa increased, the first-order branches grow faster, the branching angle increased, and the overall branching rate was lower. The results of this study will be helpful to understand the branching pattern and the adaptive strategies of the poplar, and provide a theoretical basis for making the reasonable pruning measures. © 2021, Editorial Department of Scientia Silvae Sinicae.
