摘　　要：采用中国农科院生产的中农26号黄瓜种子为试验材料,在中农-Ⅲ型育苗设施内研究了黄瓜育苗时不同光照强度与光照时间配比对幼苗质量的影响。试验结果表明,光照强度和光照时间存在交互作用,当光照强度为174.3μmol.m-2.s-1、光照时间为14 h时,黄瓜幼苗生长发育最好,各项指标均为较优,即在中农-Ⅲ型育苗设施中育苗时,采用此光环境培育中农26号黄瓜较为适宜。Taking the seeds of Zhongnong No.26 cucumber as material,we studied the effects of different light intensities and light duration on cucumber seedlings in ZN-Ⅲ seedling facility.The results showed that the interaction effect between light intensity and light duration existed,and cucumber seedlings grew best and had better growth indexes under the condition with the light intensity of 174.3 μmol·m-2·s-1 and light duration of 14 hours,thus the light environment was suitable for cultivating cucumber seedlings in ZN-Ⅲ seedling facility.
