Abstract: Abstract: In this paper, the field experiments were carried out to study the effects of controlled-release BB fertilizer applied on soil enzymes activities during different growth stages of watermelon. The results showed with the application of controlled-release BB fertilizer, the activities of soil urease, neutral phosphatase and sucrose were better than conventional fertilizer treatment because of the significantly controlled release effects of the controlled-release BB fertilizer.
