摘　　要：研究了不同缩二脲含量的尿基复合肥作基肥和种肥时,在不同的水分条件下对玉米、小麦出苗的影响。结果表明:复合肥中的缩二脲含量、施肥方法和水分条件都对玉米、小麦出苗有很大影响,小麦对缩二脲的忍耐性强于玉米,含缩二脲超标的尿基复合肥在施用时需要谨慎。A study is carried out of the effect of different biuret content in urea-based compound fertilizer applied as basal fertilizer and seed fertilizer to germination rate of maize and wheat under different moisture conditions. Results show that biuret content in fertilizer, application methods and moisture conditions all play an important part in germination of maize and wheat, the tolerance of wheat to biuret is stronger than that of maize, and applying urea-based compound fertilizer with biuret exceeding standard need to be careful.
