摘 要：
采用连续水浸提、盆栽试验,研究不同温度下两种促释材料活化的磷矿粉磷素动态释放特性及肥效。结果表明:(1)与磷矿粉相比,促释磷矿粉连续浸提水溶性磷累积量显著提高;提高幅度最大的是经加温处理的WZ促释磷矿粉,较未加温处理提高了42.95%,是磷矿粉的2.13倍。表明活化磷矿粉经加温处理能明显促进磷矿粉水溶性磷的释放。(2)促释磷矿粉肥效显著优于磷矿粉,WZ处理效果较佳,加温处理后肥效最佳,不亚于SP。

摘 要：
With the combination of continuous water extraction and pot experiment, the effects of the two promotedrelease materials at different temperature on phosphorus releasing dynamics of phosphate rock were studied.The major results were summarized as follows:(1) Compared to phosphate rock, the accumulative rate of water-soluble phosphorous in promoted-release phosphate rock(PRPr) was signifi cantly increased, and that of WZ-PRPr with heating was increased by 42.95% than PRPr, and by 2.13 times than phosphate rock.(2) The fertilizer effect of PRPr was more signifi cant than that of phosphate rock.Among them, the best treatment is WZ-PRPr with heating, which was as good as super-phosphate fertilizer, and the second is WZ treatment.
