衢州地处浙江西南部红壤丘陵盆地,种桔历史悠久。但因周期性冻害和旱害的影响,使“衢州西乡航埠滨河一带”成为衢州、龙游柑桔栽培的中心。到建国初期,该带的柑桔面积约占总面积的一半;产量曾达12万多担,结果面积的平均亩产为2000多斤。1961～1972年间,随着温州蜜柑、椪柑等柑桔良种价格的调高,使衢州柑桔主栽品种,逐步从衢桔和广橙,更换成温州蜜柑和桠柑,随着桔区人口增长,粮棉桔争地争肥矛盾日趋严重,柑桔生产长期粗荒栽培,又屡遭冻旱,使桔树幼龄期延长,柑桔年产量仅达4万余
Quzhou is located in red soil hills and valleys in southwestern Zhejiang Province and has a long history of cultivation. However, due to the effects of cyclical frost damage and drought, the “Quzhou Xixiang Port Port area” became the center of Quzhou and Longyou citrus cultivation. By the early days of the founding of the People’s Republic of China, the citrus area of the belt accounted for about half of the total area; the output had reached more than 120,000 and the average yield per acreage was 2000 kilos. From 1961 to 1972, with the increase of the prices of the citrus varieties such as Wenzhou Satsuma and Citrus Sinensis, the main citrus varieties of Quzhou were gradually changed from Quercetin and Cantonese orange into Wenzhou Satsuma and Citrus grandis, , The dispute between grain cotton and cotton to compete for land increasingly serious conflicts, long-term rough cultivation of citrus production, but also repeatedly freeze drought, orange juvenile period, citrus annual output of only 40,000
