摘　　要：为进一步准确评价缓控释肥对玉米产量及经济效益的影响,分别在宁夏原州区、彭阳县、隆德县和灵武市开展3种缓控释尿素(释放期分别为45 d、60 d、90 d)不同施肥方式试验研究。结果表明,原州区T1处理的玉米增产率最高,为18.59%;灵武市T1处理的玉米收益最高,较常规施肥增收2018.85元·hm^(-2),产投比达3.14。4个试验点玉米施用缓控释肥处理增产效果均好于常规施肥,增收效益明显。缓控释尿素由于价格较高(普通尿素的2倍),虽然可使玉米增产较多,但纯收益没有优势。缓控释尿素价格如果能降低,则市场优势将会更加明显。In order to further accurately evaluate the impact of controlled-release fertilizer on corn yield and economic benefits,an experiment was carried out in Yuanzhou District,Pengyang County,Longde County and Lingwu Municipality in Ningxia using different fertilization methods with three kinds of controlled-release urea(release periods of 45 days,60 days,and 90 days respectively)as test materials.The results showed that the yield increase rate of maize treated by T1 in Yuanzhou District was the highest(18.59%).The income of maize treated by T1 in Lingwu Municipality was the highest,with an increase of 2018.85 yuan ohm^(-2) compared with conventional fertilization,and the income to investment ratio was 3.14.The results of 4 experimental sites showed that the yield increase effect of slow controlled release fertilizer was better than that of conventional fertilizer,and the yield increase benefit was obvious.Due to the high price of slow-release urea(2 times that of ordinary urea),although the corn yield increased more,there was no advantage in net income.If the price of slow release urea can be reduced,the market advantage will be more obvious.
