| 摘 要： | 研究控释BB肥(掺混肥)对土壤中酶活性的影响,为控释肥的推广使用提供理论依据.采用田间小区试验法研究了控释BB肥对西瓜不同生育期土壤脲酶、中性磷酸酶和蔗糖酶活性的影响.在试验条件下,由于控释BB肥对养分的显著控释效果,它的施用对土壤中这三种酶活性的影响要好于习惯施肥处理. |

| Abstract: | The study aimed to study the effects of controlled-release BB fertilizer (fertilizer blending) applied on soil enzymes activities and provided the theoretical base for the population of controlled-release fertilizer. In the field plot test, the effect of the controlled-release BB fertilizer on soil urease, neutral phosphatase and sucrose enzymes activities during different growth stages of watermelon were studied. The results showed with the application of controlled-release BB fertilizer, the activities of these three enzymes were better than conven-tional fertilizer treatment because of the significantly controlled release effects of the controlled-release BB fer-tilizer. |
| Keywords: | ontrolled-release bb fertilizer urease enzyme neutral phosphatase enzyme sucrose enzyme |
