调查研究了环剥对富士苹果树枝类构成、树势、枝干病害等的影响。结果表明,5年生富士苹果树其环剥次数与中短枝比率及单株花序数均呈正相关关系,与树势呈负相关关系;主干环剥次数与轮纹病呈正相关关系,即环剥次数越多,树势越弱,病害越重。作者认为:生产上树势衰弱,枝干病害严重,甚至死亡的园片主要是由于环剥次数过多、剥口过宽、结果过多、以及管理粗放造成的。对5~10年生富士苹果树进行有限次数的隔年环剥,同时加强肥、水、病、虫害管理,可提高其早期产量,并能保持树势健壮
The effects of girdling on the composition of tree branches, tree vigor and branch diseases of Fuji apple were investigated. The results showed that there was a positive correlation between the number of ring stripping and the ratio of short and short branches and the number of inflorescences in the 5-year-old Fuji apple tree, which was negatively correlated with the tree vigor. There was a positive correlation between the number of trunk girdling and ring rot disease, The more times, the weaker the tree, the heavier the disease. The author believes that the production of the tree is weak, serious disease and even death of the branches of the park is mainly due to the number of ringing too much, too wide, too many results, and extensive management caused. A limited number of perennial splinters of 5 to 10 year-old Fuji apple trees, while strengthening management of fertilizer, water, disease and pest, can improve their early yield and maintain the robustness of the tree
