对 3年生冬枣幼树进行了环剥的研究 ,结果表明 :展叶期环剥0 .3～ 0 .5cm宽 ,对其生长的抑制作用较为理想 ,过宽则树势衰弱 ;在生理落果初期环剥 0 .4cm宽 ,其采前座果和单株产量分别是对照的 2 .93倍和 2 .2 5倍。
The results of the ring peel study on the jujube jujube with 3-year-old showed that: the ring-peeling was 0.3-3.0 cm wide at the leaf-setting stage, and its growth inhibition was more ideal. When it was too wide, Girdling 0 .4cm wide, its pre-harvest fruit and per plant yield were 2.93 times and 2.25 times the control.
