桂中地区柠檬引种表现及品种搭配的思考

Study on the Growth Performance of Three Lemon Introduced Varieties in Central Guangxi

探讨比较适宜桂中地区生态条件下种植的柠檬品种,为相近生态区域发展柠檬生产品种选择提供参考,通过对"北京柠檬"、"台湾四季香水柠檬"和"安岳尤力克柠檬"等3个品种的树体生长、开花结果特性、果实性状、适应性、抗病虫害性和市场行情调查。发现不同品种树体生长量差异明显;开花次数、开花期和持续时间差异较大;各品种的果实品质差异明显;品种的适应性和抗病虫害性个体差异独特;市场供求行情已发生改变。"台湾四季香水柠檬"抽梢能力强、开花结果性能好,柠檬酸含量高,果实批发价格稳定,需求量大,适应性好,高抗溃疡病,可作为主栽品种;"安岳尤力克柠檬"没有原产地果实皮薄果色金黄亮丽的优势,只能作搭配品种;"北京柠檬"产量低,品质一般,适应性和抗病虫害差,不宜在桂中南地区种植。

This article studies the tree growth, flowering and fruiting characteristics, fruit characters, adaptability, resistance to diseases and pests and market quotation of three lemon varieties including ＂Beijing lemom＂, ＂Taiwan perfume lemon＂ and ＂Anyue Eureka lemon＂ to find the suitable variety for planting in central Guangxi, and provides reference for lemon production and variety selection in the similar ecological areas. The results showes that there are significant differences in the tree growth increment, florescence, fruit quality, price stabili- ty, adaptability, resistance to diseases and pests and and market quotation between different varieties. ＂Taiwan perfume lemon＂ can be used as the main planting variety with the advantages of strong sprouting ability, good flowering and fruiting characteristics, high content of citric acid, stable fruit wholesale price, great demand, good adaptability, best resistance to canker; ＂Anyue Eureka lemon＂ can only be used for the matching variety without the advan- tages of thin skin, bright golden color as it being in the original producing area; and ＂Beijing lemom＂ should not be grown in central and southern Guangxi due to its low yield, general quality, poor adaptabity and bad resistence to diseases and pests.
