荔枝是我国南方佳果,自古名闻中外。我省长期以来荔枝繁殖沿用高压技术,其操作简便,但此法对母树损害较大,采用较大枝条,所产苗木不多,不适应良种推广与大规模栽培要求。同时高压苗多采取衰枝、密枝、荫枝、病虫枝,其生势差、品种杂,影响结果与品质,甚至有长期不结果现象;近年来逐渐被实生嫁接苗所代替。 Lychee is good fruit in southern China, ancient and famous Chinese and foreign. In our province, the litchi propagation has been used for a long time. Its operation is simple and convenient. However, this method has great damage to the parent tree and uses larger branches, with few seedlings and unsuitable for the popularization and large-scale cultivation of elite. At the same time, the high-pressure seedlings take more branches, dense branches, shade branches, branches and pests, and their potential difference, variety miscellaneous, affecting the results and quality, and even long-term no result; gradually replaced by grafted seedlings in recent years.
