为确定本土化的水稻推荐施肥参数，建立施肥指标体系，对近年来贵州各施肥分区“3414”肥料效应田间试验数据进行分析，建立不同施肥分区下籼型杂交稻的养分吸收量、土壤有效养分校正系数、肥料当季利用率等施肥参数。结果表明，利用养分平衡法确定土壤供肥量和水稻需肥量，设计肥料配方，配方施肥区实际产量与设定的目标产量的平均吻合度为93．89％。推荐施肥参数的确定解决了水稻施肥指标体系不系统或缺失的问题，为水稻产前定肥和肥料配方设计提供依据，提高了推荐施肥技术方案的可靠性。

To obtain Guizhou recommended indica hybrid rice fertilization parameters and form the localized,precise fertilization technology system of rice with high quality and high yield,"3414"fertilizer effect and nutrient test values of plant and soil of each fertilization zoning in Guizhou recently were analyzed, then fertilization parameters such as nutrient uptake, soil nutrient supply and fertilizer utilization rate of rice in different fertilization zoning were established.Based on the nutrient balance method,soil fertilizer consumption and rice fertilizer requirement were determined, and the designed fertilizer formula was used,so that the average alignment between actual yield and setting target yield of prescript fertilization zoning was 93.89%.The determing of recommend fertilization parameters which is helpful to improve the imperfect fertilization technology system of rice, provides some basis for rice prenatal fertilizer and fertilizer formula design,and increases the reliability of the recommend fertilization technology solutions.
