利用浦北县测土配方施肥项目采集的试验数据、野外调查和室内化验结果等资料,综合当地专家经验和知识,按照国家耕地地力评价程序与方法,计算出耕地的土壤肥力综合指数,用于测土配方施肥所需的生产潜力、土壤供肥能力、单位产量需肥量、肥料利用参数的模型建立及参数估算,以水稻为例,探索了县域施肥指标体系建立的方法,提出的不同肥力水平的配方肥配方,经过验证和在生产中应用,效果较好。
Based on the experimental data collected in the soil testing and fertilization project in Pubei County, the field investigation and indoor laboratory results, the comprehensive index of soil fertility of cultivated land was calculated according to the national evaluation procedures and methods of land productivity based on the experience and knowledge of local experts. The production potential of soil testing and formula fertilization, the soil fertility, the amount of fertilizer required per unit yield, the model establishment of fertilizer utilization parameters and the parameter estimation. Taking rice as an example, this paper explores the method of establishing fertilization index system in county, The level of formula fertilizer formula, validated and applied in production, the better.
