通过对温室盆栽玉米进行传统施肥、普通硫基复合肥、新型硝硫基复合肥3种施肥处理,分析和探讨新型硝硫基复合肥对玉米生长情况及产量的影响。结果表明,施用50 kg/667 m²新型硝硫基复合肥相对于等量的其他2种施肥方式,穗质量分别提高32.2%、10.1%;穗粒数分别提高17.9%、13.2%;穗粒鲜质量分别提高20.4%、15.7%;穗粒干质量分别提高19.6%、14.3%。因此,施用新型硝硫基复合肥(N-P_2O₅-K_2O:15-15-15)相对于传统施肥方法和施用普通硫基复合肥(N-P_2O₅-K_2O:15-15-15),可以明显提高玉米的穗质量、穗粒数和穗粒质量,对玉米有着显著的增产效果。

The current research investigated the application effects of a new nitrate of S-based compound fertilizer on the growth and yield of maize using a pot experiment. Conventional fertilizers, a common S-based compound fertilizer, and a new nitrate of S-based compound fertilizer were applied to pot soil; the three fertilization treatments were compared in their effects on maize growth and yield. The results showed that the treatment with a new nitrate of S-based compound fertilizer(15-15-15) produced the optimal effect among the three treatments. Compared to conventional fertilizers and a common S-based compound fertilizer, the new fertilizer(15-15-15) led to increases in panicle weight by 32.2% and 10.1%, respectively; in grain number per spike by 17.9% and 13.2%,respectively; in grain fresh weight by 20.4% and 15.7%, respectively; and in grain dry weight by 19.6% and 14.3%, respectively. Taken together, the new nitrate of S-based compound fertilizer(15-15-15) can significantly improve panicle weight, grain number per spike,and grain weight of maize; therefore, it has a significant effect of increasing maize yield.
