As of April 2017, the planting area of Citrus grandis in Ruili City was 594.3 ha. Among it, the area of fruiting trees was 267.2 ha, and they were mainly owned by small growers. In view of the serious fragmentation of pomelos, the large investment in fertilizers, and the unsatisfactory production efficiency of C. grandis in Ruili, the fertilization technology for C. grandis was discussed. The problems in the fertilization process, as well as the principles and modes of fertilization were analyzed briefly. The fertilization methods for saplings and fruiting trees were introduced, in order to promote the improvement of the fertilization and management level of local pomelo growers.
