研究目的西瓜枯萎病分布于全世界的西瓜栽培区,它是一种古老的难治之症。近几年来,我市西瓜栽培面积逐年扩大,轮作倒茬越来越困难,西瓜枯萎病已成为西瓜生产上一个突出问题。据调查,在武清县南蔡村乡、石各庄乡以及宝坻县牛道口乡等一些老瓜区,由由枯萎病的严重发生,许多瓜农不得不弃瓜种菜。瓜农们反应,在轮作4～5年之久的土地上种西瓜,仍然大片死亡,重茬地上更是棵瓜无收。迫切要求科研部门尽快提供防治西瓜枯萎病的技术措施。
Research purposes Watermelon Fusarium Wilt distribution in the world’s watermelon cultivation area, it is an ancient intractable disease. In recent years, the city’s watermelon cultivation area has been expanding year by year, rotation cropping more and more difficult, watermelon blight has become a prominent issue in the production of watermelon. According to the survey, some cuckoo areas in Nancai Village, Shigezhuang Township in Wuqing County and Niu Dao Kou Township in Baodi County were seriously affected by the blight and many melon farmers had to abandon the melons and vegetables. The melon farmers responded that they planted watermelons on the land that had been rotated for 4 to 5 years and still died in large tracts of crops. It is urgent for scientific research departments to provide technical measures to prevent and treat watermelon blight as soon as possible.
