摘　　要：为明确育苗移栽对玉米生育进程、植株性状及产量构成的影响，以郑单958和京单68为材料进行了试验，结果表明：移栽处理后玉米株高、穗位高、穗长和穗粒数分别较直播对照下降，但生育进程明显提前7-10d，灌浆较充分，子粒含水量降低26．9％和31．3％，产量增加12．3％和10．4％，郑单958产量差异达到显著水平。In order to understand the effect of seedling transplant on the growth process ,agronomical characters, yield and its components of summer maize, a field experiment was conducted using maize cultivars,Zhengdan 958 and Jingdan 68. Comparing with direct seeding treatment, seedling transplant treatment decreased the plant height ,ear height, ear length,grain number per ear ,and grain moisture content,Seedling transplant shortened the growth process from 7 to lOd,decreased the grain moisture content by 26.9% and 31.3% ,increased the yield by 12.3% and 10. 4% ,however only the Zhendan 958 yield increase was significant.
