通过花生氮肥田间肥效试验、摸清花生栽培过程中不同氮肥用量标准的施肥效应,掌握氮肥的最佳施用量,确定科学、合理的施肥技术,提高花生生产科技水平和肥料利用率,为建立施肥指标体系提供依据。筛选验证氮肥不同施肥量情况下、作物养分吸收量和肥料增产结果、构建作物施肥模型、为分区施肥和肥料配方提供科学依据。
Peanut nitrogen fertilizer through field experiments to find out the peanut cultivation of different nitrogen application rates of fertilizer effect, to master the optimum amount of nitrogen fertilizer to determine scientific and rational fertilization techniques to improve peanut production technology and fertilizer utilization, in order to establish fertilizer Indicator system to provide the basis. Screening to verify the nitrogen fertilizer under different fertilizer levels, crop nutrient uptake and fertilization yield results, the construction of fertilization model for the district to provide a scientific basis for fertilizer and fertilizer formulations.
