平和县琯溪蜜柚几年来发展很快。1990年全县种植近三万亩,比1985年增长100倍以上。近万亩目前正处于挂果阶段的3—5年生初产树,存在着只长梢不开花,或开花多,挂果少的现象。为了解决这个矛盾,我们根据琯溪蜜柚的生育特性和几年来各地的实践经验。1989年底对初产树(适龄树)提出以环状剥皮,为主的六条丰产技术措施,首先在县琯溪蜜柚科技示范中心的西林示范片120亩推广环剥。1990年10月平均单产2401公斤,比原指标1500公斤,增产60.2%,现综述如下:一、环状剥皮;是琯溪蜜柚初产树(适
Pinghe Guanxi pomelo developed rapidly over the past few years. In 1990 the county planted nearly thirty thousand acres, more than 100 times more than in 1985. Nearly mu is currently in the fruiting stage of 3-5 years of primiparous trees, there is only the long shoots are not flowering, or flowering, hanging fruit less phenomenon. In order to solve this contradiction, we based on the fertility characteristics of Guanxi honey pomelo and the practical experience of the past few years. At the end of 1989, six high-yielding technical measures were put forward on the first generation tree (suitable age tree) in the form of ring-shaped peeling, and the first step was to promote girdling in the 120-hectare Xilin Model Zone of the Pomelo Technology Demonstration Center of Xiangye River. October 1990 average yield 2401 kilograms, than the original indicator of 1500 kilograms, an increase of 60.2%, are summarized as follows: First, the ring peeled;
