温州蜜柑嫁接苗种植后,一般三年就开花结果,但也有到适龄不结果的植株,如昆明市富民县何光营桔园,1980年定植的温州蜜柑(尾张),植后四年生的适龄结果幼树2328株,到1984年8月,有528株仍不结果,占22.7％。为了缩短适龄不结果树的无效生长期,我们选择生长旺盛或生势较好的部份植株,分别进行环割或圈枝处理,均获得了 Wenzhou Satsuma grafted seedlings planted, the general flowering results in three years, but there are also age-unsuccessful plants, such as Kunming Fumin He Guangying Orange Park, planting Wenzhou Mandarin orange (tail) in 1980, four years after implantation Age-appropriate results young tree 2328, August 1984, there are 528 still no results, accounting for 22.7%. In order to shorten the inefficient growing season of unsuitable trees, we choose the plants with strong growth or better vigor,
