| 中文摘要: |
| 试验采用二因素二次饱和D最优设计方法,对锌锰施用量的配合及基与干旱区玉米产量间的关系进行了研究。结果表明,锌锰肥对玉米均有增产量效应,锌肥作用尤为明显,锌肥的增产效应明显大于锰肥。同时筛选出了锌锰肥配合优化组合方案,玉米产量3800kg/hm2以上的锌锰配合优化组合方案为:锌3.3008kg/hm2,锰4.608kg/hm2。 |
| 英文摘要: |
| The experiment adopted the two-factor D-optimum repercussion layout to study the relationship of applied amounts of Zn and Mn fertilizers with maize yield in arid regions. The experimental results showed that both Zn and Mn fertilizers remarkably increased maize yield with the former remarkably surpassing the latter in yield increment; meantime, it screened out the best combination of Zn and Mn fertilizers. |
