摘要
以6年生‘沙红’和‘燕红’桃树为试材,研究不同骨干枝角度对桃树生长和果实品质的影响。结果表明:‘沙红’直立树和‘燕红’骨干枝倾斜30°的总枝量,中枝、短枝和花束状枝总和以及枝条生长量明显高于其他2个处理;同一部位,‘沙红’直立树和‘燕红’骨干枝倾斜30°的总枝量处于较高的水平,高于其他2个处理;同一方向,‘沙红’和‘燕红’3个处理均是平侧枝总枝量最高。同一部位,‘沙红’直立树和‘燕红’骨干枝倾斜30°的果实品质好于其他2个处理;同一方向,‘沙红’和‘燕红’3个处理的结果数均是平侧枝最多;‘沙红’直立树和‘燕红’骨干枝倾斜30°的果实品质和产量显著高于其他2个处理。因此,‘沙红’骨干枝适宜的倾斜角度为0°,而‘燕红’骨干枝适宜的倾斜角度为30°。
Six-year-old‘Shahong’and‘Yanhong’as the test materials,to study the effects of the different backbone branches angle on peach tree growth and fruit quality.The results showed that the erect tree of‘Shahong’and the backbone branches angle of 30°for‘Yanhong’were significantly higher than the other two treatments for the total branch volume,the sum of middle branch,short branch and bouquet branch,and the growing branches.In the same place,the erect tree of‘Shahong’and the backbone branches angle of 30°for‘Yanhong’of the total branch volume were at a high level,higher than the other two treatments.In the same direction,the three treatments of‘Shahong’and‘Yanhong’were the highest for the total branch amount of flat side branch.In the same place,the erect tree of‘Shahong’and the backbone branches angle of 30°for‘Yanhong’for fruit quality were higher than the other two treatments.In the same direction,the three treatments of‘Shahong’and‘Yanhong’were the highest for the number of fruits of flat side branch.The erect tree of‘Shahong’and the backbone branches angle of 30°for‘Yanhong’for the fruit quality and yield were higher than the other two treatments.Therefore,the suitable inclination angle of the backbone branches was 0°for‘Shahong’,while the suitable inclination angle of the backbone branches was 30°for‘Yanhong’.
