Abstract Fusarium wilt is an important factor causing clogging in continuous cultivation of
watermelon〔Citrullus lanatus（Thunb.）Matsum. et Nakai〕．In production，we generally adopt crop
rotation，grafting，biological control and medical treatment to prevent this disease．This experiment
studied on many controlling methods，such as grafting on different stock varieties，using biological
pesticides and biological fertilizer，etc．at different plot of land during the period of watermelon
continuous cultivation．The results indicated that the effect of biological control was not obvious，if
the continuous cultivation period was long，and watermelon was planted in the fields where Fusarium
wilt occurred seriously. Biological control could only play an inhabiting role in dome extent，while the
grafted seedling had remarkable effect，the control effect is 100.0%．If the continuous cultivation
period was short，and the plot had slightly suffered from Fusarium wilt，it was efficient to apply BIO
biological fertilizer or grafting.
