瓯柑是温州市传统的柑桔品种,有悠久的种植历史。主要分布于平廉老桔区的瓯海、鹿城、龙湾三个县(区)。瑞安、平阳、永加等县(市)的局部区、乡也有较多栽培。全市现有瓯柑2.5万亩,约占全市柑桔总面积的9％。1987年瓯柑产量为2.2万吨,约占全市柑桔总产的42％。 该品种进入结果龄期较早,产量高,但也存在着较明显的大小年现象。近几年来,瓯海县睦州垟村等少数桔农,对瓯柑实行短截或回缩修剪,对缩少瓯柑大小年幅度,提高产量,取得了明显效果,一般可增产16～45％。目前这一方法在睦州垟村已应用推广300多亩,并在继续扩大之中。现将瓯柑短截和回缩修剪钓效应调查总结如下,供参考。
Orange is the traditional citrus varieties of Wenzhou City, has a long history of cultivation. Mainly located in Lianghua, Lucheng and Longwan counties of Pinglou Old Orange District (district). Ryan, Pingyang, Yongjia county (city) of the local area, the township also has more cultivation. The city’s existing 2.5 million mu of orange, accounting for about 9% of the city’s total citrus.
