| 英文摘要 | Fixation of ammonium-N from fertilizer by soil clay minerals and its subsequent release is of significance in regulating soil N supply for plants, preventing N losses, and improving fertilizer N use efficiency. Taking a black soil from Jilin of Northeast China as the test soil, a pot experiment consecutively cropped with spring wheat-buckwheat-spring wheat was conducted, aimed to evaluate the effects of different ((NH4)-N-15)(2)SO4 fertilization practice on the amount and subsequent release of soil recently fixed fertilizer (NH4+)-N-15 in the test soil over the consecutive crop cultivation. 19.60-30.88% of applied (NH4+)-N-15-N was fixed after 10 days of fertilization, suggesting that the black soil had a higher potential of fixing fertilizer NH4+-N. During the consecutive crop cultivation of spring wheat-buckwheat-spring wheat, an average of 80.95%, 7.13% and 2.27% of soil recently fixed (NH4+)-N-15-N was released in the first, second, and third crop cultivation, respectively. This indicates that the release of soil recently fixed fertilizer NH4+-N is a relatively long-term process, and it was quite active in the early period of fixation and easily utilized by the first crop cultivation. High N application rate increased significantly the fixation and release of applied (NH4+)-N-15-N (P < 0.01). To improve the use efficiency of ammonium fertilizers in the crop production of black soil in Northeast China, the soil recently fixed fertilizer NH4+ should be taken into account when an advanced nitrogen management strategy was to be developed.
