随着西瓜生产的不断发展和栽培面积的扩大，连作引起的土壤传播病害──镰刀菌枯萎病已日渐猖獗。嫁接栽培不仅能有效地防治枯萎病，而且对于根系的耐低温伸长性、耐热性、耐湿性和耐旱性都有重要的作用。但任何一项农业技术的发展，都不可能十全十美，嫁接也是如此。西瓜嫁接 With the continuous development of watermelon production and the expansion of cultivated area, the soil transmission disease caused by continuous cropping - Fusarium wilt disease has become increasingly rampant. Grafting cultivation not only can effectively prevent and treat wilt disease, but also has an important effect on the low temperature elongation, heat resistance, moisture resistance and drought tolerance of the root system. However, any one of the development of agricultural technology can not be perfect, as is grafting. Watermelon grafting
