| 【目的】研究不同水分处理对无土栽培黄瓜根系的影响。【方法】以“津优35”黄瓜为材料。在日光大棚内的无土栽培种植沟内种植，设置6组不同的水分处理，采用根系专用扫描仪Epson V800进行根系图像扫描，并用WinRHIZO根系分析软件对之进行分析。【结果】（1）基质上限为田持100%时，水分处理T1根系形态参数最大。（2）基质上限为田持85%时，水分处理T6根系形态参数最大。（3）水分处理T3下的黄瓜直径2 mm以下和8 mm以上根系占比总根系的62.7%。（4）水分处理T5下的黄瓜直径2 mm以下和8 mm以上的根系占比总根系的66.4%。（5）T1、T2和T3的根系干重占鲜重的比值分别为21.7%、21.4%和12.6%，T4、T5和T6分别为9.1%、9.0%和9.3%。【结论】在无土栽培条件下黄瓜可以通过适当控制水分上，下限含量调节根系分步。当相同水分下限条件下，上限为田持100%的处理的黄瓜根系形态参数高于水分上限为田持85%的处理。随着设施农业的发展，无土栽培技术得到了广泛的应用。通过不同水分处理对无土栽培黄瓜根系的影响研究，为无土栽培作物的需水规律研究提供理论依据。 |

| Abstract:【Objective】To study the effects of different water treatments on cucumber roots in soilless culture.【Method】Using "Jinyou 35" cucumber as material. Six groups of different water treatments were set up in the soilless cultivation ditch in the sunlight greenhouse. The root images were scanned by Epson V800, a special root scanner, and analyzed by WinRHIZO root analysis software.【Result】(1)When the upper limit of substrate was 100%, T1 root morphological parameters were the largest. (2)The maximum root morphological parameters of T6 under water treatment were obtained when the upper limit of substrate was 85%.(3) water treatment T3, cucumber roots with diameter less than 2 mm and more than 8 mm accounted for 62.7% of the total roots. (4) water treatment T5, cucumber roots with diameter less than 2 mm and more than 8 mm accounted for 66.4% of the total roots. (5) The ratio of root dry weight to fresh weight of T1, T2 and T3 was 21.7%, 21.4% and 12.6%, respectively. (6)T4, T5 and T6 were 9.1%, 9.0% and 9.3%, respectively.【Conclusion】Under soilless culture, cucumber roots can be adjusted by properly controlling the upper and lower limits of water content. Under the same water limit condition, the root morphological parameters of cucumber treated with the upper limit of 100% were higher than those treated with the upper limit of 85%. With the development of facility agriculture, soilless cultivation technology has been widely used. The effect of different water treatments on cucumber roots was studied to provide a theoretical basis for the study of water requirement of soilless crops. |
