| 摘 要： | 采用淹水培养间歇淋洗法、淹水密闭连续培养法和淹水培养间歇多次淋洗法对四种稻田土壤进行土壤氮素矿化的淋洗试验。结果表明：淋洗有利于土壤氮素的矿化过程，但淋洗频率过快并没有造成土壤氮素矿化量的显著增加。

| Abstract: | Four paddy soil samples were used for the analysis of soils nitrogen mineralization with several experiment methods,including waterlogged incubation,waterlogged incubation plus intermittent leaching and waterlogged incubation plus intermittent leaching of increase the leaching frequency.The results showed that:leaching was beneficial to soil mineralization,but the accumulation of the nitrogen mineralized in the soils would not be higher with increasing of the leaching frequency. |
