Nutrient Use Efficiency of Rice in Plain River District
摘要
Abstract
[Objective] To research the nutrient use efficiency of rice in Plain River District.[Method] By using field experiment, we researched the effects of conventional fertilization and formulated fertilization treatments on rice yield , fertilizer input, apparent efficiency of fertilizer, fertilizer agronomical efficiency, nutrient contents in rice seeds, stems and leaves.[ Result] The apparent efficiency of fertilizer was the best under combined application of nitrogen, phosphorus and potassium.Formulated fertilization treatment improved the fertilizer agronomical efficiency and fertilizer nutrient use efficiency, promoted the absorption of nitrogen, increased yield by 3.45％ and income by 944.2 yuan/hm2 compared with conventional fertilization.[Conclusion] This research provides theoretical basis for the optimization of fertilization structure and the enhancement of fertilizer nutrient use efficiency.关键词
