在中国农业大学倡导的氮肥总量实时监控、磷钾肥恒量平衡监控法的基础上,结合烟台测土配方施肥实践,总结出一套测土配方施肥方法:根据某地块的养分含量(NO3-N,P,K)及目标产量,计算各养分的推荐施肥量;填写施肥建议卡,反馈给被测地块农户,提出施肥建议。其特点是量化和公式化,增加了可操作性。
Based on the real-time monitoring of the total amount of nitrogen fertilizer and the constant balance monitoring of phosphorus and potassium fertilizer advocated by China Agricultural University, a set of soil testing and fertilization methods were summarized based on the practice of soil testing and formula fertilization in Yantai. According to the nutrient content (NO3- N, P, K) and the target yield, calculate the recommended amount of fertilizer for each nutrient; fill in the suggestion card, feedback to the measured plots of farmers, put forward fertilization recommendations. Its characteristics are quantified and formulated, increasing maneuverability.
