采用正交试验,以颗粒抗压强度及产品原料成本为目标,确定了以NH_4Cl为基体的颗粒复混肥最适宜配方。在此基础上,进行了淋失模拟试验,讨论了该类复混肥的淋失特性。
Orthogonal experiments were carried out to determine the optimal formula of granular compound fertilizer based on NH_4Cl with the compressive strength of granule and raw material cost as the target. On this basis, the leaching loss simulation test was carried out, and the leaching characteristics of the compound fertilizer were discussed.
