功能性复合肥对盐碱地冬小麦产量及养分吸收的影响

摘要

为了研究功能性复合肥对盐碱地冬小麦产量及养分吸收的影响,将腐植酸钾、氰氨化钙及锌与氮、磷、钾原料一同制备的功能性复合肥施用于小麦,统计冬小麦产量并计算养分利用率.结果表明:功能性复合肥能够增加盐碱地小麦产量,提高其籽粒氮、磷、钾的养分累积量.通过计算籽粒养分利用率(籽粒氮、磷、钾养分累积量/施入氮、磷、钾量),腐植酸钾、氰氨化钙及锌三种物质能够促进氮、磷、钾从肥料向籽粒中转移.%In order to study the effect of functional compound fertilizer on yield and nutrient uptake of winter wheat in saline, the compound fertilizer, made by potassium humate, calcium cyanamide and zinc and nitrogen, phosphorus and potassium raw materials, were applied on winter wheat in saline. The results showed that this compound fertilizer increased the wheat yield and increase the nitrogen, phosphorus and potassium of grainaccumulation. The Calculations of nitrogen, phosphate, potassium nutrition efficiency showed that potassium humate, calcium cyanamide and zinc could promote the transfer of nitrogen, phosphorus and potassium from fertilizer to grain.
