Abstract:
The aim of study was to explore effects of palmitic acid on disease incidence of watermelon Fusarium wilt,soil chemical properties,and soil enzymes,which was performed over pots experiment.The results showed that disease incidence of watermelon Fusarium wilt decreased gradually with concentration increasing of palmitic acid.Palmitic acid at all concentrations elevated activities of urease and neutral phosphatase,but reduced intervase activity.Soil available N,available K,and pH increased with concentration increasing of palmitic acid.Whereas available P and organic matter showed reverse trends.Palmitic acid at concentration of 0.5 mmol?kg-1 significantly increased available P.1.5 mmol?kg-1 palmitic acid significantly increased available K.Disease incidence of watermelon Fusarium wilt was positive related with available K and intervase activity,but negative related with available N and urease activity.Totally,palmitic acid influenced soil chemical properties and enzymes activities,especially controlled watermelon Fusarium wilt.
