摘要
为建立县域测土配方施肥指标体系参数,并应用施肥指标体系参数成果指导配方肥生产和农业生产中科学合理施肥。本研究通过对土壤养分和田间植株养分吸收量的分析,应用专业背景知识和数理统计方法,总结出1套县域施肥指标体系参数,并应用到配方施肥的具体实践中,建立了简化操作的表格化参数选取方案和套用公式的施肥推荐计算方法,从而使准确应用养分平衡法指导施肥成为现实。此体系具有较高推广应用价值。
To establish the soil testing and fertilizer recommendation index system parameters in counties, and guide the production of formulated fertilizer and scientific reasonable fertilization in agriculture production by applying the parameters, the soil nutrient and nutrient absorption by plants were analyzed. The soil testing and fertilizer recommendation index system parameters in counties were summarized, which was applied in practice. The scheme of simplified tabular parameters selection was established. Using the formulas, the nutrient balance could be realized.
