摘　　要：[目的]研究适宜塔罗科血橙新系的控旺长促花技术,提高产量。[方法]针对4年生植株,进行不同促花处理,研究不同处理对塔罗科血橙新系产量的影响。[结果]采用拉枝+环割+多效唑处理,即7—9月,对直立的旺长枝进行拉枝(扭枝、吊枝、撑枝),9月对大枝实施环割2~3圈,配合喷施1次15%多效唑500倍,可以极大地促进塔罗科血橙新系花芽分化,确保来年丰产。[结论]拉枝+环割+多效唑处理促花效果好,经济高效,可全面推广到塔罗科血橙新系生产中。[Objective]To research the efficient technologies on control of vigorous growth and promoting flower-formation on tarocco blood orange nucellar line and effectively solve the problem of low yield.[Method]Different treatments were pruned in 4 years-old trees,and the impact on yield was detected.[Result]The treatment of branch-pulling pruning+girdling+paclobutrazol was the best combination.It mean that in July-September,pulling upright flourishing branches(twisting,hanging or propping branches),and in September,girdling 2 to 3 circles on the large branches,and matching once of 500 times of 15% paclobutrazol,could greatly promote flower-formation on tarocco blood orange nucellar line and ensure the output.[Conclusion]Branch-pulling pruning+girdling+paclobutrazol got the best result of flower-formation promoting,which is efficient and effective and can be fully applied to the production of tarocco blood orange nucellar line.
