摘要
文章主要针对国内外关于长期氮磷钾化肥和有机肥配施条件下土壤氮、磷和钾养分动态变化及其相关平衡方面的研究,主要包括养分的全量及有效量的动态变化、氮、磷和钾在土壤中的存在方式、形态以及彼此之间的转化等,总结分析研究成果,并提出相关的可行性建议。
This paper mainly focuses on the dynamic changes of soil nitrogen, phosphorus and potassium nutrients and their related balances under the conditions of long-term N, P, K fertilizers and organic fertilizers, including the dynamic change of total and effective nutrients, the existing patterns, forms and transformation of N, P, K nutrient in the soil, etc., then summarizes and analyzes the re-search results and puts forward relevant feasibility suggestions.
