摘  要:
[目的]为提高玉米产量找到适宜的施肥方式提供参考。[方法]以玉米为试验材料,采用施肥比例试验和施肥量试验统一在同一试验中的研究方法,研究了氮磷不同量比对玉米产量的影响。[结果]在把土壤和作物结合起来考虑时,作物苗期土壤供肥存在特定施肥比例。在一定施肥水平范围内,随着氮磷施用量的增加,玉米产量增加,且存在特定的施肥比例。[结论]在平衡施肥中,除了氮磷施用量之外,氮磷之间有一个合适的施肥比例。

摘  要:
[Objective]The research aimed to provide the reference for the appropriate fertilization mode to increase the maize yield.[Method]Effects of different fertilization ratio and dosage on yield of maize were studied with fertilizer application amount experiment and fertilizer application ratio experiment. [Result]Below the application amount at pole,crop yield increased linearly with the increase of application amount and there was a specific application ratio considering soil and crop at the same time. [Conclusion]Under the balanced fertilization,except the fertilization amount of nitrogen and phosphorus,there was a appropriate fertilization ratio between nitrogen and phosphorus.
