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,结合小麦生长需肥规律和目标产量施肥配方方法,对固原市原州区小麦种植合理施肥进行研究。结果表明,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。在此基础上提出了固原市原州区小麦种植适宜方案。
The status of soil nutrient in Yuanzhou county of Guyuan city was analyzed and the rational application of fertilizer for wheat was studied based on the rule of fertilizer requirement and target yield of wheat. The results showed that the soil in Yuanzhou county was alkaline. Organic matter, nitrogen, phosphorus, zinc, and sulphur in this soil were deficient, especially sulphur. The contents of iron and manganese were in middle and inferior level. While potassium was rich, and copper could basically meet the crop growth. Based on the present situation of soil nutrient, the optimum planting scheme for wheat was proposed.
