英文摘要 | We conducted a pot experiment with spring wheat to examine the effects of microbial immobilization/mineralization and soil mineral fixation/defixation on nitrogen (N) conservation and supply and determine the influences of inhibitors and straw additions on these processes. Results showed that the effects of fixed NH4+ pool on N conservation and supply were 3.1- and 2.2-fold, respectively, of the effects of soil microbial biomass N (SMBN) pool in the treatments without straw and 1.3- and 1.4-fold, respectively, of the effects of the SMBN pool in the treatments with straw application. In the absence of straw, the nitrification inhibitor (dicyandiamide, DCD) and urease inhibitor (hydroquinone, HQ) improved crop yield. Conversely, crop yield declined when straw was used especially in combination with DCD. Meanwhile, HQ alleviated the decrease in crop yield induced by straw application. These phenomena were attributed to the fact that DCD coupled with straw further enhances microbial immobilization and decreases N availability. HQ delayed the hydrolysis of urea, asynchronizing the microbial immobilization and NH4+ supply and consequently mitigating the decline in N availability. Both inhibitors regulated the fixed NH4+ release, especially the DCD. In general, DCD tends to conserve N in soil and lowers N availability, whereas HQ is favorable for the maintenance of N in mineral forms and increasing its availability. |
