摘要： 以发酵鸡粪、精制有机肥和生物有机肥作为供试肥料,研究了不同有机肥料中氮素的矿化特征。研究结果表明,三种有机肥料在出苗前矿化速率都比较缓慢,但后期不同有机肥料间矿化速率不同。精制有机肥从苗期到收获矿化速率比较均匀,阶段矿化率在6%-7%之间,氮素总矿化量为27.02%；鸡粪氮素总矿化率最高,为30.48%,阶段矿化率最高出现在旺长前期,为11.39%；生物有机肥中氮素总矿化率最低,为26.11%。对作物生长的影响结果显示,施用精制有机肥既增加了生姜的产量又降低了生姜硝酸盐含量,施用生物有机肥显著提高了生姜产量,对生姜硝酸盐含量没有影响,而施用发酵鸡粪虽然增加了生姜产量,但也提高了生姜的硝酸盐含量。

Abstract: A field experiment was conducted to study nitrogen mineralization characteristics by the application of fermented chicken manure, refined organic fertilizer and bio-organic fertilizer. The results showed that nitrogen mineralization rates were slow before seedling emergence under the three organic manure treatments, but they were different in the late stage. Nitrogen mineralization rate of refined organic fertilizer was uniform from seedling stage to harvest, stage mineralization rate was 6%- 7% , the total amount of nitrogen mineralization was 27.02%; the total nitrogen mineralization rate of chicken manure was the highest of 30.48%, and the maximum value of stage mineralization rate was in the early stage of vigorous growing period of 11.39% ; the total nitrogen mineralization rate of bio- organic fertilizer was the lowest of 26.11% . The application of refined organic fertilizer increased ginger yield and reduced nitrate content, bio- organic fertilizer could improve the yield of ginger, but had no effect on nitrate content, fermented chicken manure increased both yield and nitrate content.
