摘　　要：在大石桥市进行一次性基施缓释尿素、基追施常规施肥和一次性基施普通尿素的水稻田间试验。试验结果表明:一次性基施缓释尿素处理的水稻叶色变化正常,与常规施肥处理的水稻长势相当;一次性基施缓释尿素能明显提高水稻穗粒数,与一次性基施普通尿素处理相比增产效果极显著,与基追施常规施肥处理相比产量差异不显著;一次性基施缓释尿素不用追肥,可以节省投入成本。Experiments were conducted in the rice fields in Dashiqiao city to give single basal fertilization of slowly-releasing carbamide, basal dressing regular fertilizing and single basal fertilization of common carbamide. The results show that when given single basal fertilization of slowly-releasing carbamide, the rice leaf color remains normal, and the rice grow just as well as those given regular fertilization. The practice of single basal fertilization of slowly-releasing carbamide can remarkably increase the number of rice panicles and the yields increase significantly compared with those given single basal fertilization of common carbamide while there is no evident difference in yields compared with those given basal dressing regular fertilizing. Another advantage of single basal fertilization of slowly-releasing carbamide is that there is no need to give additional fertilizer, hence, saving input cost.
