摘要
以黄瓜为试材,研究不同灌溉温度对日光温室黄瓜幼苗动态生长的影响,探讨促进黄瓜幼苗生产的最佳灌溉水温。结果表明,用温水灌溉温室黄瓜幼苗可提高幼苗的茎粗、叶面积、根系数、光合速率、单位鲜质量的干物质量、根冠比和壮苗指数等指标,处理的效果由大到小依次为40℃处理、30℃处理、50℃处理、20℃处理、对照(12℃),在生产上有一定的推广和利用价值。
The cucumber was selected to study different irrigation temperature on dynamic growth of cucumber seedlings in greenhouse.In this way,the best irrigation temperature would be found to promote seedlings of cucumber growth.The results showed that treatments of different irrigation temperature improved stem diameter,leaf area,root factor,photosynthetic rate,dry matter quality of Unit fresh weight,root-shoot ratio,seedling index.Treatment effect was as follows： 40 ℃ treatment,30 ℃ treatment,50 ℃ treatment,20 ℃ treatment,CK（12 ℃）.The results had some promotional and useful value in production.
