小国光苹果果实酸甜、多汁、肉质细脆、耐贮运,是我国晚秋至早春果品市场上受欢迎的品种。在我省苏北苹果主产区,小国光是晚熟主栽品种,如淮阴市的栽培面积占苹果总面积的44％。但小国光容易发生采前裂果,发生轻的年份和果园,裂果率为10％左右,发生重的年份和果园裂果率高达70％。此外,烂果病(炭疽病)也是小国光苹果生产中的重大问题,烂果率一般在10％以上,病重的果园果实未及成熟已近全部腐烂。据1982～1984年在苏北苹果产区试验证明,果实套袋是花钱少,效益高,易为果农掌握的防病、防裂果技术。
Small country apple fruit sweet and sour, succulent crisp, crisp, resistant to storage and transportation, is China’s late autumn to early spring fruit market popular varieties. In our province, the main producing area of apple in northern Jiangsu, Xiaoguangguang is a late-maturing cultivars, such as Huaiyin City, cultivated area accounted for 44% of the total area of the apple. However, the small country easily lead pre-harvest cracking light, light years and orchards, cracking rate of about 10%, occurred in heavy orchards and fruit cracking rate as high as 70%. In addition, rotten fruit disease (Anthrax) is also a major issue in the production of Apple Apple, the rotten fruit rate is generally above 10%, the orchard fruit is less than mature and almost completely decayed. According to the 1982 to 1984 apple production in northern Jiangsu proved that bagging fruit is less money, high efficiency, easy for farmers to master the disease prevention, anti-fruit technology.
