摘    要:为了探讨缓释尿素和普通尿素配合施用对提高水稻的产量、氮肥利用率的影响,通过采用添加不同比例的控释尿素的方法,对其在水稻上的产量和利用率进行了研究。结果表明,在施氮量相等的条件下,缓释尿素与普通尿素搭配施用与普通尿素相比,可使水稻增产7.8%~20.3%,氮肥利用率提高8.0~13.2个百分点。综合考虑,搭配比例以缓释尿素占总氮量的50%~70%为好。

Abstract:The aim to research the effects of control released urea and common urea on rice yield and fertilizer use efficiency, in this experiment effect of controlled releasing urea on rice production was investigated by adding different proportions of controlled release urea. The results showed that: in the condition of equal amount of nitrogen, the mixture of common urea and control released urea could increase 7.8%-20.3% of rice yield and increase 8.0%-13.2% of N use efficiency than only application of common urea. Taken together, the best ratio of control released urea to total N was 30%.
Keywords:nitrogen use utilization
