| 摘 要： | 采用密闭箱法对不同施肥条件下小麦田中羰基硫(COS)、二硫化碳(CS2)和二甲基硫(DMS)的释放情况进行了监测.结果表明,小麦生长过程对COS、CS2和DMS释放影响显著,小麦对COS有明显吸收作用,DMS和CS2是麦田中释放的主要含硫气体.COS和CS2释放速率昼夜变化明显.仅施用有机肥的麦田,硫释放总量高于其它田块.不同施肥条件的田块,硫释放总量范围在-1.40～0.79mg·ml-2之间.

| Abstract: | Emission rates of carbonyl sulfide (COS), carbon disulfide (CS2) and dimethyl sulfide (DMS) to the atmosphere from wheat fields treated with different fertilizers were measured by using the closed chamber method. The results showed that the emission rate of COS, CS2 and DMS was affected by wheat growth and COS was absorbed by the plants. DMS and CS2 were the predominant sulfur gases emitted from these fields. The diurnal variations of emission rates of COS and CS2 were obvious. The sulfur flux in the plot treated with organic fertilizer was higher than that in the other plots. The sulfur fluxes from different plots were in the range of -1.40 to 0.79 mg·m-2. |
