锦橙 Citvus sinensis 果形美观(呈椭圆形)、颜色鲜艳、果皮中等厚、甜酸适度、味浓汁多、微具香气、果心小、半充实耐贮藏,是我国柑桔优良品种之一,出口的主要品种。目前在四川、贵州、湖北甜橙区大量推广种植。但在生产上,锦橙开花多,座果率低,不能高产,川西地区有些果园开始改换其它柑桔品种,影响锦橙的发展与出口。为了解决这个问题,1977年四川省农科院果树研究所周光洁等同志做了锦橙人工授粉试验,并发表了试验初报,但因锦橙开花期短,大面积种植后,采用人工授粉确有困难。我们于1980年4月下旬至12月上旬在崇庆县偏僻丘陵山区的怀远公社果园利用蜜蜂为锦橙进行授粉试验,现将试验情况初报于后。
Citrus sinensis is beautiful in shape (oval), brightly colored, with medium-thick peel, moderate sweetness and acidity, little bitterness and aroma, with a small fruit core and semi-sufficient storage, which is one of the fine varieties of citrus in China , The main export varieties. Currently in Sichuan, Guizhou, Hubei orange a lot of promotion of cultivation. However, in production, the flowering of Jincheng, fruit set rate is low, can not be high yield, some orchards in western Sichuan began to change other citrus varieties, affecting the development and export of Jincheng. In order to solve this problem, in 1977, Sichuan Academy of Agricultural Sciences Institute of Fruit Zhou Guangjie and other comrades made orange pollination artificial pollination test and published the first report, but the flowering Jin Jin short period, large-scale planting, the use of artificial pollination There are indeed difficulties. In late April to early December 1980, we conducted a pollination test using orange bees in the orchards of Huaiyuan Commune in remote mountainous areas of Chongqing County.
