近年来,柑桔市场竞争日趋激烈,四川柑桔在北方市场上逐渐失去优势地位,一个很重要的原因就是品质较差,具体表现为:品种杂乱、等级混杂、果小、味酸、色淡等,要尽快改变这种状况,除了抓好技术管理、合理施肥、适时采摘、分级出售外,积极主动的办法便是推广高接换种,去杂去劣,从根本上杜绝劣种来源,尤其是对作为四川主栽品种锦橙,如园内混有零星夏橙、实生甜橙及其它变异劣种更应坚决换掉,以期提高柑桔的群体品质,增强其竞争力。高接换种的技术并不难掌握,一般的幼苗嫁接技术方法都可用在高接上,如芽片协接、腹接、楔形小芽 In recent years, citrus market is increasingly fierce competition, Sichuan citrus in the northern market gradually losing its dominant position, a very important reason is the poor quality, as follows: the variety of messy, mixed grades, small fruit, pickled, pale In order to change this situation as soon as possible, in addition to doing a good job in technology management, rational fertilization, timely picking and grading, the proactive approach is to promote the promotion of diversification, miscellaneous and inferior behavior, fundamentally eliminate sources of bad seeds, In particular, as the main varieties of Jincheng in Sichuan, such as the park mixed with sporadic summer oranges, sweet oranges and other real variants should be resolutely replaced, in order to improve the quality of citrus groups and enhance their competitiveness. High exchange of technology is not difficult to master, the general method of seedling grafting technology can be used in the high access, such as splicing, splicing, wedge-shaped small bud
