本研究主要从降低包膜肥料的成本出发,以复合改性矿物为包膜材料制成的包膜尿素作为研究对象。利用土壤培养实验,通过测定包膜内残留的养分含量,研究不同土壤水分、土壤质地、土壤温度等环境条件对包膜尿素在土壤中氮素释放速率的影响,希望能对复合改性矿物包膜肥料的制造、施用提供科学的依据。 This study mainly from the cost of reducing the cost of coated fertilizers, composite modified minerals as coated material coated urea as the research object. The effect of environmental conditions such as soil moisture, soil texture and soil temperature on the nitrogen release rate of coated urea in soils was studied by soil culture experiments. The content of residual nutrients in the coating was determined. Membrane fertilizer manufacturing, application to provide a scientific basis.
