| 摘 要： | 大田条件下，研究了种植密度、施氮量、施氮方式、喷施植物生长调节剂（玉黄金）等主要栽培措施对玉米新品种中单808产量的影响。结果表明：中单808高产适宜种植密度为45 000株/hm2，氮肥合理施用量为施纯氮225 kg/hm2，施用方式为播种前、拔节中期分两次按60∶40比例施入；喷施玉黄金对中单808产量形成具有明显效应，适宜喷施时期为14展叶期，喷施量为产品推荐量的1/2，增产效果显著。 |

Effects of Main Management Factors on Yield of Maize Hybrid Zhongdan808 |
|
| Abstract: | Effects of planting density, nitrogen rate and timing, spraying plant growth regulator (Yu-Huang-Jin) on yield of maize hybrid Zhongdan808 were studied under field conditions. The results showed that the suitable planting density was 45 000 plants/ha,the maximum yield was obtained at nitrogen rate of 225 kg N /ha.As for timing of N application, the best operation was splitting the N application into two times, 60% of the total N being applied before planting, the remainder of the N applied at growth stage of medium-term of shooting.Obvious effects of spraying Yu-Huang-Jin on yield were observed, the highest yield occurred when half of the recommendation concentration of Yu-Huang-Jin was sprayed at 14th leaf stage. |
