京欣二号西瓜是攀枝花地区主栽的西瓜品种之一,其外观漂亮,整齐,产量高,上市早。其果肉脆爽、瓜瓤红色,口感好,甜度高,含糖量为12%以上,深受消费者喜爱,在攀枝花市已有较大的设施栽培面积。近几年,随着瓜类设施栽培面积不断扩大,轮作周期缩短,大多数西瓜品种连作障碍日趋严重,枯萎病等土传病害大面积发生,造成西瓜产量下降、品质降低,制约了西瓜产业的可持续发展。实践表明,嫁接换根是解决西瓜连作障碍和土传病害的有效措施之一。本实验通过不同砧木对京欣二号西瓜嫁接生长发育状况、产量、品质等方面的研究,以期筛选出适宜在攀枝花地区种植的嫁接京欣二号西瓜的优良砧木品种。
Jingxin No. 2 Watermelon is one of the main varieties of watermelon in Panzhihua. Its appearance is beautiful, tidy, with high output and early listing. Its crisp flesh, melon red, good taste, sweetness, sugar content of 12% or more, loved by consumers, in Panzhihua City has a larger facility cultivation area. In recent years, with the increasing cultivation area of melons, shortening the rotation cycle, the continuous obstacle of most watermelon cultivars, the serious occurrence of soil-borne diseases such as blight and so on, resulting in the decrease of watermelon production and the decrease of quality, restricting the development of watermelon industry sustainable development. Practice shows that grafting for roots is to solve continuous obstacles and soil-borne watermelon disease effective measures. In this experiment, different rootstocks were used to study the growth, yield, quality and other aspects of the grafting of Jingxin No.2 watermelon in order to select the good rootstock varieties suitable for grafting watermelon Jingxin No.2 in Panzhihua.
