通过氮、磷、钾肥料量级田间试验,可以掌握各个施肥单元不同作物优化施肥数量,基、追肥分配比例、施肥时期和施肥方法,摸清土壤养分校正系数、土壤供肥能力、不同作物养分吸收量和肥料利用率等基本参数;构建作物施肥模型,为施肥分区和肥料配方提供依据。通过花生氮磷钾肥料量级多块地试验,试验结果以及大体规律在中等肥力表明花生产量高低与氮、磷、钾肥料搭配有直接关系,以667m2施纯氮10.00kg、五氧化二磷6.00kg、氧化钾8.00kg配合施用有机肥400.00kg的处理的667m2产量表现较好。
Through the field experiments of nitrogen, phosphorus and potassium fertilizers, we can know the optimal fertilization amount, base and top dressing allocation ratio, fertilization period and fertilization method in different fertilization units, find out the soil nutrient correction coefficient, soil fertility, nutrient content of different crops Absorption and fertilizer utilization rate and other basic parameters; construction of crop fertilization model for fertilizer division and fertilizer formulations provide the basis. Through peanut NPK fertilizers on the level of block test, the results and the general rule in the medium fertility showed that the level of peanut production and nitrogen, phosphorus and potassium fertilizer with a direct relationship to 667m2 applied nitrogen 10.00kg, phosphorus pentoxide 6.00 kg, 8.00 kg of potassium oxide with the application of organic fertilizer 400.00kg 667m2 yield performance better.
