| 摘 要： | 采用室内恒温控湿好气培养法,研究了掺混不同C/N比有机物料土壤中有机氮的矿化进程,及有机碳源添加对其的影响。培养 30周的结果表明:掺混大豆粉的土壤有机氮的矿化速率最快,在第 30d时达到最大;掺混玉米秸粉土壤有机氮的矿化速率最慢;有机碳源的添加明显抑制了有机氮的矿化进程,但这种抑制作用只是暂时的,最终将以有机氮的矿化分解为发展总趋势。

| Abstract: | A laboratory aerobic incubation test was conducted under constant temperature and moisture to study the mineralization process of organic nitrogen in organic material with different C/N ratio and the effect of organic carbon added on it The results showed that the mineralization rate of organic nitrogen in soil and soybean mixture was the fastest, reaching the maximum on the 30th day, the mineralization rate of organic nitrogen in soil and corn stalk mixture was the slowest, the addition of organic carbon evidently inhibited the mineralization process of organic nitrogen While, this inhibition was temporary, the ultimate development trend was the mineralization of organic nitrogen |
