不同类型氮肥对夏玉米产量及经济效益的影响

摘要

The field experiment was conducted to investigate the effects of different types of nitrogen fertilizers on summer maize yield and economic benefits. The results showed that the selected three kinds of nitrogen fertilizers increased the summer maize yield, effective panicle number and grain number per spike significantly. Considering yield and economic benefit, using inexpensive compound fertilizer had the best increasing effects on summer maize yield and farmer's income.%通过田间小区试验研究了不同类型氮肥对夏玉米产量及经济效益的影响,结果表明,所用的3种类型氮肥(复混肥、缓释肥和复合肥)均使夏玉米产量、有效穗数和穗粒数显著提高,从产量和经济效益综合比较,以施用物美价廉的复合肥对夏玉米的增产与农民的持续增收效果最佳.
