近年来,市面上出售的脐橙,多数果个偏小,单果重仅120～150克,味道偏酸,其原因是:栽培海拔超过500米,有效积温不够;品种不良;栽培管理不当;果实采摘偏早;致使果色淡黄,味酸,不耐贮藏。为了保持脐橙固有的特点,提高产量,现简述其高效栽培技术如下: 1.严格按区域种植宜在长江两岸、溪河两旁海拔500米以下,年有效积温5700～6000℃,果实成熟期昼夜温差大的地区栽培。
In recent years, most of the navel oranges sold in the market are small in fruit size. The fruit weight is only 120-150g. The reason is: the cultivation elevation is over 500m, the effective accumulated temperature is not enough; the varieties are not good; the cultivation is not properly managed; the fruit picking Too early; resulting in fruit color yellow, Pickle, intolerant storage. In order to maintain the inherent characteristics of navel orange and increase yield, the following is a brief description of its efficient cultivation techniques: 1. Strictly according to the region planted in the two sides of the Yangtze River, river elevation 500 meters below the effective accumulated temperature of 5700 ~ 6000 ℃, maturity of the day and night Cultivation in areas with large temperature difference.
