我国栽培的柑桔,主要分布在南、中、北亚热带,以宽皮柑桔类居首,其次是甜橙类。为了探索柑桔果树的生态适宜性,我们与生产柑桔的有关省、市、自治区的领导、科研、教学、生产等单位协作,以气温为主要指标,结合考虑其它生态因子,对我国的甜橙类和宽皮柑桔类(以温州蜜柑为代表)进行了生态适宜性区划研究。 Citrus cultivated in our country are mainly distributed in the south, middle and north subtropics, with citrus species covered with broad-leaved citrus, followed by sweet orange species. In order to explore the ecological suitability of citrus fruit trees, we collaborate with the leaders, scientific research, teaching and production units of the relevant provinces, municipalities and autonomous regions in producing citrus. Taking the temperature as the main index and considering other ecological factors, Oranges and broad-leaved citrus (represented by Wenzhou orange) were studied for ecological suitability.
