摘要
为研究新型缓控释肥料的应用模式,采用对比试验的方法,开展玉米施肥田间试验。试验结果表明:新型缓控释肥料比测土配方推荐施肥增产6.93%,经济效益增加78.03元/667 m2,氮肥利用率增加19.5个百分点;应用新型缓控释肥料,施氮量减少10%是可行的。
In order to study the application of new type controlled release fertilizer, the field experiment of maize fertilization was carried out with the method of comparative experiment. The experimental results showed that： The new controlled release fertilizer increased yield by 6.93% compared with the recommended fertilizer for the soil test formula, the economic benefit increased by 78.03 yuan/667 m^2, and the nitrogen fertilizer utilization rate increased by 19.5 percentage points; It is feasible to reduce the amount of nitrogen by 10% by using the new controlled release fertilizer.
