脐橙是柑桔的一个品种,在国际市场上享有较高的声誉。脐橙由于无核、味甜、肉脆、化渣、富香气,经济价值高,在鲜果市场极受欢迎。我国引种脐橙已有50多年的历史,目前以四川、广东、广西栽培较为集中。浙江、江西、湖南、湖北、云南、贵州和福建等省试种也初步获得成功。然而,普遍存在的一个问题是低产或无产。当前要发展脐橙,建立高产栽培基地,就必须解决这个问题。脐橙在我国引种地出现低产的主要原因之一是品种生态适应性问题。美国、日本、西班牙等国均通过芽变选择的方法,按照本国产地的自然地理特点,选择出适应当地的丰产、质优的华盛顿脐橙品系。
Orange is a variety of citrus, enjoy a high reputation in the international market. Navel orange is very popular in the fresh fruit market because it has no core, sweet taste, crisp meat, slag, rich aroma and high economic value. The introduction of navel orange has more than 50 years of history in our country. At present, cultivation in Sichuan, Guangdong and Guangxi is more concentrated. Zhejiang, Jiangxi, Hunan, Hubei, Yunnan, Guizhou and Fujian provinces have also achieved initial success. However, a common problem is low or no production. At present, to develop navel oranges and establish high-yielding cultivation bases, we must solve this problem. One of the main reasons for the low yield of navel orange introduced in our country is the ecological adaptability of varieties. The United States, Japan, Spain and other countries through the choice of budding method, according to the natural geographical features of their origin, choose to adapt to the local high yield, high quality Washington Navel orange lines.
