为了掌握乌恰县小麦生产优化施肥数量,基肥、追肥分配比列,土壤养分校正系数,养分吸收量,土壤供肥能力和肥料利用率参数,建立合理的施肥指标体系,根据测土配方施肥技术项目特安排本实验。为了更好地探测出乌恰县各种作物的最佳施肥比例、施肥时期、施肥方法,建立合理的施肥指标体系,掌握乌恰县各个施肥单元不同作物,优化施肥数量、基肥、追肥分配比例,土壤养分校正系数,土壤供肥能力和不同作物养分吸收量和肥料利用率参数,构建作物施肥模型,为施肥分区和肥料配方提供科学依据,根据测土配方施肥技术项目的要求特安排本试验。
In order to grasp the quantity of optimized fertilization, wheat base fertilizer, top dressing distribution ratio, soil nutrient correction coefficient, nutrient uptake, soil fertility and fertilizer utilization rate in Wuqia County, a reasonable fertilization index system was established. According to soil testing and fertilization technology Special arrangements for the project. In order to better detect the best proportion of fertilizers for various crops in Wuqia County, fertilize time and fertilize method, set up reasonable fertilization index system, grasp the different crops of fertilization units in Wuqia County, optimize the amount of fertilization, the ratio of basal fertilizer and top dressing , Soil nutrient correction coefficient, soil fertility and nutrient uptake of different crops and fertilizer utilization rate parameters, the model of crop fertilization was constructed to provide scientific basis for fertilization division and fertilizer formula. According to the requirements of soil testing and fertilization technology project, .
