以晋黍9号为材料，研究了普通尿素和缓释尿素对糜子产量和品质的影响。结果表明：施氮处理的糜子蛋白质含量都显著大于对照，而淀粉含量都显著小于对照；产量以PN2（普通尿素150 kg·hm－2）最高，增产幅度为28．48％；产量与穗数和单株粒重达到极显著正相关，相关系数分别为0．81和0．62；糜子产量与籽粒蛋白质含量呈极显著正相关，相关系数为0．83，与籽粒淀粉含量呈显著负相关，相关系数为－0．44。本试验条件下，糜子产量的增加主要是通过增加穗数和单株粒重来实现的。以普通肥料N150 kg · hm－2为最适施氮量。研究表明不是所有土壤类型都适合施用缓释尿素，研究区为砂质土，保水保肥能力差，通气性好，施用普通尿素比缓释尿素效果好。

To study the effects of different nitrogenous fertilizers on the yield and quality of broomcorn millet ,Jinshu 9 was used as the material in this study .The results showed that protein content was significantly greater than CK ,and starch content was significantly less than CK .The highest yield was by the treatment of PN2 ,with an increasing rate at 28 .48% .Yield displayed a significant positive correlation with panicles and grain weight per plant ,and the correlation coefficients were 0 .81 and 0 .62 ,respectively .Millet yield was significantly positive correlation with grain protein content with a correlation coefficient at 0 .83 ,and was negatively correlated with the grain starch content with a correlation coeffi-cient at -0 .44 .Under the experimental conditions ,increasing the yield of broomcorn millet mainly through the increase of panicles and grain weight per plant .The level of nitrogen application at 150 kg·hm-2 was found to be optimal in this region .We can see are not all soil types are suitable for the slow-release urea .The types of sandy soil retention of fat and water ability is poor ,air permeability is good ,so more suitable for the ordinary urea .
