Analysis of comprehensive comparative advantages of main citrus producing areas in Yuxi

针对云南省玉溪市柑桔品种多、杂、乱、老、劣,品质下降,区域布局欠合理,导致柑桔果品季节性过剩,销售难现象时有发生的问题,在调查玉溪市柑桔各主产县(市)柑桔种植环境条件及主栽品种特性、抗逆性、种植效益等情况的基础上,进一步采用比较优势指数分析方法对玉溪市柑桔各主产县(市)柑桔业的优劣进行研究。结果表明,玉溪市柑桔主栽的“宫本”“大浦”“兴津”“冰糖橙”“沃柑”等品种具有较强的抗逆性和丰产性,比国内其他柑桔产区相同品种成熟早,对抢占市场较为有利,种植效益较高。华宁县和新平县为玉溪市柑桔优势产区,元江县具有成为优势产区的潜力,易门县、峨山县、通海县和澄江市为一般产区。结合柑桔产业发展实际情况,提出了玉溪市柑桔品种结构和区域布局建议。
