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。
Under the experimental conditions, thiourea has obvious yield-increasing effect on nitrogen fertilizer and can be used as a synergist of nitrogen fertilizer. Thiourea in paddy field the best application rate of 27.7kghm-2, 1kg thiourea can increase the yield of 25.7kg rice, rice yield 9.0%, and the ratio of nitrogen to nitrogen 0.2: 1, can be used as rice growth and yield formation safety Amount. The optimal dosage of thiourea in maize field was 39.9kghm-2,1kg thiourea could increase the yield of corn by 22.2kg, the yield increase by 10.2% and the ratio of nitrogen fertilizer to 0.19:1, which could be used as the safe dosage for the growth and yield formation of corn.
