Ganzhou City, Jiangxi Province has a large scale of navel orange planting, the largest planting area, the third annual output in the world, and the largest navel orange producing area in China. Ganzhou mountainous area is dominated by Quaternary red soil, with a small amount of purple soil and mountain yellow soil. The soil layer is deep, and a high standard navel orange orchard can be built with a little modification.
The soil condition is good. Red loam has the characteristics of deep soil layer, acidic soil and low organic matter content, which is suitable for navel orange growth. Ganzhou is a typical subtropical humid monsoon climate, with four distinct seasons, abundant rainfall, abundant sunshine, long frost-free period, large temperature difference between day and night in September ~165438+1October, and the same season of rain and heat, which is very beneficial to navel orange planting.
Gannan navel orange is listed as one of the eleven dominant agricultural products in China and has won the reputation of "China Famous Fruit". Gannan navel orange, as the only product in Jiangxi Province, was shortlisted in the list of geographical indication products negotiated by the Ministry of Commerce and the AQSIQ.
Variety introduction
In the selection of navel orange varieties, Xinfengyu 197 1 introduced Washington navel orange from Shaoyang, Hunan, with excellent performance. 1979, Huazhong agricultural university introduced a new strain of navel orange 12 from the United States and Spain, 198 1 year, and Professor Zhang Wencai selected 8 of them to plant in Gannan.
After more than ten years of experiment, domestication and comparison in southern Jiangxi, some excellent varieties such as Newhall, Penna and Nevina suitable for planting in warm and humid climate in southern China were screened out.
Later, in the specific production practice, Newhall was favored by the majority of fruit farmers and became the main variety because it was superior to Penner and Nevilina in fruit shape, color and flavor. The area of Newhall navel orange accounts for 88% of the total area of navel orange, while Bona and Nevina only account for 8% and 3% respectively.
