摘　　要：[目的]探究散射光薄膜在日光温室中的适用性,开展黄瓜育苗和栽培试验研究。[方法]试验以‘中农16号’品种黄瓜为材料,对比测试了散射光薄膜和同类普通薄膜覆盖下的温室黄瓜生长性状指标。[结果]在散射光薄膜B3.6(雾度36.2%)覆盖下,黄瓜苗期壮苗指数显著提高27.31%;在散射光薄膜B4.2(雾度39.65%)覆盖下,黄瓜定植后的叶片数、叶面积、地上/下部鲜重均显著高于对照组,并且雌花开花节位降低1.13个、开花时间提前1.53d,最终获得17.72%的增产。[结论]初步结果表明,散射光有利于黄瓜的生长发育,散射光薄膜在日光温室黄瓜栽培中具有较好的应用前景。[Objective]In order to explore the applicability of the diffuse light film in China Solar Greenhouse,cucumber seedling and cultivation experiments were carried out.[Methods]With the cucumber cultivar‘Zhongnong 16＇as material,the growth characteristics of greenhouse cucumber were analyzed by comparing the diffuse light film with the same type of ordinary film.[Results]The results showed that cucumber seedling index could be significantly increased27.31% under the cover of diffuse light film B3.6（haze 36.2%）;Cucumber leaf number,leaf area and ground/underground fresh weight were significantly higher than the compared group after planting.Cucumber female flowering node reduced 1.13 and flowering time was 1.53 days in advance,eventually cucumber obtained 17.72% yield increase under the cover of diffuse light film B4.2（haze 39.65%）.[Conclusion]The preliminary results indicated that the diffuse light was conducive to the growth and development of cucumber,and the diffuse light film has a good prospect in cucumber cultivation in China Solar Greenhouse.
