不同环剥宽度对灰枣生长及果实品质的影响OA

To explore the effects of different girdling widths on fruit set rate,leaf traits,fruit yield,and quality of gray jujube in southern Xinjiang,and to determine the most suitable girdling technique parameters for this production area,an experiment was conducted in 2025 in the gray jujube orchard of the 48th Regiment in southern Xinjiang.Gray jujube trees with basically the same growth vigor were selected as experimental materials,and four girdling width treatments were set:T1(3 mm girdling),T2(5 mm girdling),T3(7 mm girdling),and T4(10 mm girdling),with CK(no girdling)as the control.The effects of each treatment on fruit set rate,leaf traits,secondary branch fruiting,and fruit quality were measured and analyzed.The results showed that girdling treatment could significantly inhibit vegetative growth and increase fruit set rate,fruit quality,and yield.Among them,the 7 mm girdling had the highest overall score;its leaf thickness was significantly lower than CK,and the number of fruits on secondary branches and the yield per plant were significantly higher than CK.In current practical production,considering fruit set rate,leaf traits,secondary branch fruiting,yield,and quality,the 7 mm girdling is the optimal choice.
