Abstract通过室内模拟和塑料大棚试验,研究了普通尿素和矿物改性包膜尿素对土壤pH值及大棚内有害气体浓度变化的影响.结果表明,在室内模拟试验条件下,两种氮肥施用初期均导致土壤pH值上升,并于1周后达到最大值,上升幅度超过50%,随后开始下降,至第5周回到初始水平.大棚内施用两种氮肥均使棚内NH3、NO2和O3浓度增加,其中施用普通尿素处理的NH3、NO2日均挥发量均大于矿物改性包膜尿素;施用普通尿素处理使大棚内土壤的NH3、棚内NO2和O3的最高浓度达到42.36、41.95和86.00μg.m-3.d-1,3种气体浓度均达到了有害气体伤害植物的临界阈值;NH3、NO2挥发强度受棚温和光照强度的影响,O3...
