| 摘要: |
| 对掺合复肥与混合复肥的制造工艺，经济效益及在玉米上的肥效进行了比较。应用对辊式造粒机，将氮磷钾基础肥料分别制在成粒径一致的粒状肥料，然后按配方要求进行计量和混匀，制成掺合复肥。与混合复肥相比，掺合复肥制造工艺简单，成本较低，其工艺能适应各种氮磷钾配比。 |

| Abstract: |
| Technology,economical benefit and its effects on maize of bulk blending (B.B.) were compared with mixed fertilizer.The ordinary fertilizer which contains nitrogen,phosphorus or potassium is granulated by roll compacter.The granular fertilizers are mixed in accordance with the prescription and turns in B.B..Compared with the mixed fertilizer,B.B.is simpler in manufacture,more economic in cost. |
