硫脲对氮肥增产效益的影响

Influence of Applying Thiourea on Yield

在本试验条件下,硫脲对氮肥有明显的增产效益,可做为氮肥的增效剂。在水田中硫脲最佳施用量27.7kghm-2,1kg硫脲可增加水稻产量25.7kg,可使水稻增产9.0%,与氮肥的比例0.2∶1,可做为水稻生长发育及产量形成的安全用量。在玉米田中硫脲最佳施用量39.9kghm-2,1kg硫脲可提高玉米产量22.2kg,增产幅度10.2%,与氮肥的比例0.19∶1,可做为玉米生长发育及产量形成的安全用量。

Applying thiourea obviously increased yield and efficiency of nitrogen fertilizer. Applying 1kg thiourea could make rice by 9.0%,accounting for 25.7kg.Optimal thiourea quantity is 27.7(kg hm^(-2)).Applying thiourea proportion with Nitrogen Fertilizer is 0.2∶1.
