为了玉米增产促进农民增收,更加科学合理地施用氮肥减少对环境污染的危害,通过田间随机区组试验,研究了复混肥、缓释肥和复合肥3种氮肥对夏玉米产量及穗部性状的影响。结果表明,3种氮肥都能使夏玉米的产量、有效穗数和穗粒数显著提高;从纯收入和施肥效益水平上看,施用复合肥〉复混肥〉缓释肥,以施用复合肥效果最佳。
為瞭玉米增產促進農民增收,更加科學閤理地施用氮肥減少對環境汙染的危害,通過田間隨機區組試驗,研究瞭複混肥、緩釋肥和複閤肥3種氮肥對夏玉米產量及穗部性狀的影響。結果錶明,3種氮肥都能使夏玉米的產量、有效穗數和穗粒數顯著提高;從純收入和施肥效益水平上看,施用複閤肥〉複混肥〉緩釋肥,以施用複閤肥效果最佳。

In order to increase maize yield and farmer’s income farmer is added close,more scientific and rational application of nitrogen was needed to reduce the pollution to environment,through field randomized block experiment,studied the compound fertilizer,slow-release fertilizer and compound fertilizer of 3 kinds of nitrogen fertilizer on summer corn yield and panicle traits influence.The results showed that,3 kinds of nitrogen fertilizer could make the summer maize yield,effective panicle number,grain number per spike and significantly improve;from the net income and the efficiency of fertilization level,applying fertilizer,compound fertilizer,slow-release fertilizer.From the output and economic benefits compared to the best effect,application of compound fertilizers.
