[目的]对宁夏固原市原州区玉米种植合理施肥进行研究。[方法]利用土壤养分常规分析法测定固原市原州区耕层土壤养分含量,结合玉米生长需肥规律和养分平衡计算方法,提出了玉米种植适宜的施肥方案。[结果]固原市原州区耕层土壤为碱性,养分含量整体表现为有机质、氮不足,磷、锌缺乏,硫极其缺乏,铁、锰中等偏下,钾丰富,铜基本能满足作物生长。[结论]该研究为玉米种植过程中提高产量的同时合理使用肥料、减小化肥用量、降低化肥污染提供了指导。
[Objective] The research aimed to study the reasonable fertilization of corn planting in Yuanzhou District of Guyuan City in Ningxia. [Method] The content of soil nutrient in topsoil of Yuanzhou District of Guyuan City was determined by routine analysis of soil nutrients. Based on the law of growth and demand of corn and the calculation method of nutrient balance, a suitable fertilization scheme for maize planting was put forward. [Result] The topsoil in Alluvial Plain of Guyuan City was alkalic. The overall nutrient content was organic matter. Nitrogen deficiency, lack of phosphorus and zinc, extremely lack of sulfur, moderate iron and manganese, rich potassium and basic copper could meet the crop growth. [Conclusion] The study provided guidance for improving the yield of corn during the planting process while using fertilizer rationally, reducing the dosage of chemical fertilizer and reducing the pollution of chemical fertilizer.
