摘　　要：以黄瓜为试材,采用发光二极管(LED)作为光源,在不同温度下以普通荧光灯为对照,研究纯红光(R)、纯蓝光(B)、红蓝混合光(R/B=5∶5、6∶4、7∶3)对黄瓜幼苗生长的影响。结果表明:单一色光处理下黄瓜幼苗生长不良;综合各性状表现,在光强270μmol·m^(-2)·s^(-1)、14h·d^(-1)光周期条件下,当温度控制在8h·d^(-1) 30℃、16h·d^(-1) 23℃时,红蓝光混合配比7∶3处理有利于黄瓜幼苗生长;当温度控制8h·d^(-1) 32℃、16h·d^(-1) 26℃条件下,红蓝光混合配比6∶4的处理有利于黄瓜幼苗生长。Cucumber was used as test materials,the effects of different temperature and different light qualities generated by LED on growth of cucumber seedlings were studied.Treatments were designed with red LED（R）,blue LED（B）and the complex light of red and blue LED（R/B=5∶5,6∶4,7∶3）,compared to the treatment of white fluorescent light（CK）.The results showed that the cucumber seedlings had a bad growth status under only red or blue LED.Comprehensive various characteristics,under the conditions of 270μmol·m-2·s-1light intensity and 14h·d-1 photoperiod,the treatment of R/B=7∶3LED was suitable for the growth of cucumber seedlings at 8h·d-1 30℃,16h·d-1 23℃,the treatment of R/B=6∶4LED was suitable for the growth of cucumber seedlings at 8h·d-1 32℃,16h·d-1 26℃.
