Four long-term agricultural field experiments combined with an laboratory incubation experiment were conducted to evaluate the effect of organic,inorganic and organic+inorganic fertilizer application on δ13C value of soil organic matter(SOM)and humic acid(HA)in black soil,brown soil,meadow soil and paddy soil.
以黑土、棕壤、草甸土和水稻土为供试土壤,通过田间定位并结合室内培养试验,初步研究了不同施肥(包括施用化肥、有机肥以及有机肥配施化肥)条件下全土有机质和胡敏酸的δ13C值。
The pot and incubation experiments were carried out with 10 soils by different indexes including organic matter,total nitrogen content and C/N ratio,nitrogen mineralization processes of soils are simulated using logarithmic,exponential and power functions.
通过对有机质、全氮、Ｃ／Ｎ比差异较大的１０种土壤进行盆栽和培养试验，用对数方程、指数方程、幂函数方程对土壤氮素矿化过程进行了摸拟。
