我场于一九六七年从浙江黄岩柑桔研究所引入刘勤光夏橙,进行育苗,一九六八年定植,一九七○年结果,一九七一至一九七三年陆续结果。通过几年初步观察,表明夏橙是适宜我省发展的晚熟品种。一、夏橙在本省的生长表现夏橙是一个速生快长树势强健的品种,四、五年生的幼龄结果树,树高及冠幅均达三米以上。全年抽梢三至四次,以春梢生长量为最多,立冬前后(十月下旬至十一月初旬)还会抽生少量的冬梢。枝梢抽生的物候期在闽南地区,比印子柑要提早几天,比华盛顿脐橙要迟几天。夏橙定植后,在一般管理情况下,有的植株三年即开始结果,第四年可正式投产。其现蕾开花的物候期,也是比印子柑早,此华盛顿脐橙迟。约二月初旬现蕾,二月下旬三月初旬开花,三月中旬盛花,三月下旬终花。落果期从四月下旬至六月下旬,以五月中下旬落果最
In 1967, we introduced Liu Qin-Guang Xia Orange from the Huangyan Citrus Research Institute in Zhejiang Province for breed nurseries, 1968 colonization, the results for the year 1970, and the results for the period from 1971 to 1973. After several years of preliminary observation, that summer orange is a late-maturing variety suitable for the development of our province.
