摘要： 摘要：采用田间小区试验的方法，研究了控释BB肥对西瓜不同生育期土壤酶活性的影响。结果表明：在试验条件下，由于控释BB肥对养分的显著控释效果，它的施用对土壤脲酶、中性磷酸酶和蔗糖酶活性的影响要好于习惯施肥处理。

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.
