摘要:
为了探讨在2种不同氨化-硝化复合菌剂作用下，油枯有机肥中有机氮在土壤中的氨化、硝化作用，以油枯商品有机肥为研究对象，通过室内温育培养法，研究添加氨化-硝化复合菌剂有机肥中有机氮在土壤中氨化和硝化过程。结果表明，添加氨化-硝化复合菌剂1和氨化-硝化复合菌剂2均可提高土壤氮的硝化速率(NNR），延长土壤硝化菌群的硝化活性；与未添加氨化-硝化复合菌剂油枯有机肥处理相比，培养60 d时添加氨化-硝化复合菌剂1、氨化-硝化复合菌剂2分别提高有机肥氮矿化后矿质氮累积量62.2 mg/kg和57.9 mg/kg；未添加氨化-硝化复合菌剂油枯有机肥中矿化出的矿质氮量占有机肥全氮量的比例为25.65%，添加氨化-硝化复合菌剂1、氨化-硝化复合菌剂2后，油枯有机肥中矿化出的矿质氮量占有机肥全氮量的比例分别为64.95%和61.53%，分别是未添加氨化-硝化复合菌剂油枯有机肥处理的2.5倍和2.4倍，表明2种氨化-硝化复合菌剂对油枯有机肥氮的氨化、硝化过程有较大促进作用。
Abstract:
The processes of the ammoniation and nitrification of orgonic nitrogen (N) from the organic fertilizer added with multiple species inoculants with the capacities of ammoniation and nitrification in the soil were investigated by the indoor incubation method, so as to analyse the ammoniation and nitrification of organic nitrogen in the organic fertilizer made of oil cakes. The organic fertilizer made of oil cakes was selected as the test object, and two kinds of different multiple species inoculants were used in this study. The results showed that soil nitrogen nitrification rate (NNR) increased by adding these two kinds of multiple species inoculants with the capacities of ammoniation and nitrification, and the nitrification activity of the nitrobacterium in the soil was extended. The accumulation of mineral nitrogen was increased by 62.2 mg/kg and 57.9 mg/kg by adding the microbial agent 1 and agent 2 at 60 d of culture. The ratio of mineral N to total N in organic fertilizer made of oil cakes was 25.65%, when the microbial agents 1 and 2 were added, the ratios were 64.95% and 61.53%, respectively. These results indicated that the application of two kinds of multiple species inoculants with the capacities of ammoniation and nitrification could promote the ammoniation and nitrification of nitrogen in the organic fertilizer made of oil cakes.
