Nutrient Content in Soils and Adaptability of Corn in Yuanzhou District,Guyuan City

固原市原州区土壤养分含量及玉米种植适宜性研究(英文)

[Objective] The aim was to research rational fertilization of corn in Yuanzhou District, Guyuan, Ningxia Hui Autonomous Region. [Method] Nutrient con- tents in soils in Yuanzhou District were measured with conventional analysis method and the suitable fertilization scheme of corn growth was proposed based on fertiliz- er-application rule of corn growth and nutrient balance. [Result] Soil in farmlands in Yuanzhou District was of alkalinity; organic matter, N, P and Zn were shortage; S was extremely insufficient; Fe and Mn were moderate; K was abundant; Cu would satisfy crop growth, [Conclusion] The research provides references for yield increase, reduction of chemical fertilizer and related pollution for corn growth.

[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。
