| 摘 要： | 试验在土壤灌溉下限为60%田间持水量的条件下,对不同季节温室黄瓜幼苗土壤灌溉上限进行了研究.对其生长发育及生理特性的研究结果表明:不论春茬还是秋茬,在90%田间持水量的灌溉上限条件下,幼苗叶片具有适宜的水分状况,生长发育良好,壮苗指数高,根系活力强,叶片叶绿素含量高,光合能力强,蒸腾效率高,为温室黄瓜苗期最适宜的节水灌溉上限指标.

| Abstract: | The maximum irrigation index for cucumber seedlings in greenhouse in different seasons was studied under the condition that the minimum irrigation index was 60% of field water capacity.The results of analysis on growth and development as well as physiological characteristics of seedlings showed that under the condition that the maximum irrigation index was 90% of field water capacity,whenever in autumn or spring season,the seedlings leaf had suitable water content,well growth status,high seedling growth index,strong root activity and high chlorophyll content,net photosynthesis rate and water use efficiency.So the most suitable maximum irrigation index of greenhouse cucumber at seedling stage is 90% of field water capacity. |
