摘要
研究氮肥不同施用量和施肥方式对玉米产量的影响,结果表明:在一定施肥水平范围内,随着氮肥施用量的增加,玉米产量随之增加;3种施肥方式以底肥加追肥产量最高。
Effects of application rate and method of nitrogen fertilizer on the yield of maize were studied.The results showed that under the range of fertilization level, the maize yield increased with nitrogen application rate, adopting the fertilization treatment of base and top application could get the highest maize yield.
