| 摘 要： | 【目的】 研究不同红蓝光照时间对冰菜生长发育的影响,分析其生长发育规律。【方法】 以冰菜为研究对象,以红蓝光为人工光源,在植物工厂及水培条件下,采用可循环营养液(EC2.8 dS/m,pH6.5),待冰菜幼苗长至4片叶后移植到水培立体培养系统中,设置红光与蓝光比例为(3∶1),光强统一设定为300 μmol/(m2·s),补光时间设定为8 h/16 h(光/暗)为A处理,10 h/14 h(光/暗)为B处理,12 h/12 h(光/暗)为C处理,14 h/10 h(光/暗)为D处理,16 h/8 h(光/暗)为E处理。【结果】 随着光照时间的增加冰菜叶片净光合速率也增大,冰菜在14 h光照处理下,生长形态最优,光合色素含量最高,在14 h光照下,净光合速率达到最大,但达到16 h时,净光合速率开始降低,且Fv/Fm值和Φ值最小;在14 h光照处理下抗氧化酶活性较高,在12 h光照处理下有利于可溶性糖以及VC的积累,随着光照时间的延长达到16 h时,冰菜叶片中硝酸盐含量最高。【结论】 冰菜在红蓝光比例为3∶1时,光照时间为14 h能更有利于冰菜的生长以及改善其营养品质。

| Abstract: | 【Objective】 To explore the effects of different red and blue light time on the growth and development of ice plant and to find the basic law of its growth and development.【Method】 In this experiment, ice plant was used as the research object, and red and blue light were used as artificial light sources. Under hydroponic conditions, a recyclable nutrient solution (EC2.8 dS/m, pH6.5) was used. After the cabbage seedlings grew to four leaves, they were transplanted into the hydroponic cubic culture system. The ratio of red light to blue light was set to (3∶1), the light intensity was uniformly set to 300 μmol/(m2·s), the fill light time was set to 8 h / 16 h (light / dark) for A treatment, 10 h / 14 h (light / dark) for B treatment, 12 h / 12 h ( Light / dark) for C treatment, 14 h / 10 h (light / dark) for D treatment, and 16 h / 8 h (light / dark) for E treatment. The effects of different red and blue light time on growth and nutritional quality of ice plant were studied.【Result】 The net photosynthetic rate of leaves of ice plant also increased with the increase of light time. The growth of ice plant under 14 h light treatment had the best growth morphology and the highest photosynthetic pigment content. Under 14 h light, the net photosynthetic rate reached the maximum, but at 16 h, the net photosynthetic rate began to decrease,and the Fv / Fm value and Φ value were the smallest; the antioxidant enzyme activity was higher under the 14 h light treatment, and the accumulation of soluble sugar and vitamin C was facilitated under the 12 h light treatment. As the illumination time reached 16 h, the content of nitrate was the highest in the leaves.【Conclusion】 When the red and blue light ratio is 3∶1 and the light time was 14 h, the growth of ice plant and its nutritional quality are better. |
