提高春玉米主产区玉米单产的技术途径研究

Study on Technique Way to Increase Unit AreaYield in the Main Production Zone of Spring Maize

针对进一步提高吉林省玉米单产的几个主要技术问题,探讨了玉米耕种方式、秸秆还田、改进氮肥施用技术、适宜品种种植及提高耕地质量对提高玉米单产的影响,提出提高春玉米主产区玉米单产的技术途径。

Aiming at restricting the main factors to increase the unit area yield of spring maize further,the technique ways on how to increase unit area yield in the main production zone of spring maize were discussed again.Technique ways affecting maize yield including cultivation way,returning straw into field,improving nitrogen fertilizer application way,planting good maize variety and increasing cultivated land quality were studied in this paper.
