摘　　要：采用连续浸提、盆栽试验的方法,研究促释型硼泥的养分释放特点及其肥效。连续浸提结果表明,与硼泥相比,促释型硼泥每次的水溶性镁释放量都有提高;烟草盆栽试验结果表明,与硼泥处理相比,促释型硼泥处理烟草的叶绿素含量、光合速率、生物量和镁肥利用率均更优。The methods of continuous water extraction and the pot experiment of tobacco are carried out to study the release characteristics and fertilizer effect of promoted-release boron sludge （PRBS）. The results show that compared to boron sludge, the content of water soluble magnesium of PRBS is higher every time.The results of the pot experiment indicate that chlorophyll content and photosynthesis of tobacco leaf. biomass and magnesium use efficiency of PRBS are higher than those of boron sludge.
