摘要:

为筛选出植物工厂水芹的最佳生长条件,以日本水芹为试材,采用室内LED灯为光源,利用定时器控制光周期,观察不同光周期条件下水芹的生长状况。光周期设置为24 h内4组不同的时间的明/暗交替处理(3.5 h/2.5 h、7 h/5 h、14 h/10 h、10 h/14 h)。试验结束后,检测水芹的生长与生理指标,包括维生素C、总黄酮、可溶蛋白、光合色素以及硝酸盐含量等,以探究光周期对水芹生长与品质的影响。试验结果表明,在其他条件一致的情况下,光照培养时间由10 h(10 h光-14 h暗)延长到14 h(7 h光-5 h暗-7 h光-5 h暗),有利于水芹株高增加、产量提升和品质改善。

Abstract:

To screen out the optimum growth condition of water dropwort with high yield and better quality, Japan water dropwort was used as the test material, growth experiments were conducted with indoor LED lights under different photoperiods. Four light/dark alternates (3.5 h/2.5 h, 7 h/5 h, 14 h/10 h, and 10 h/14 h) were set, and the growth parameters, such as the content of vitamin C, total flavonoid, soluble protein, photosynthetic pigment and nitrate, were measured to explore the effects of photoperiod on the growth and quality of water dropwort. The results showed that prolonging illumination from 10 h (10 h light/14 h dark) to 14 h (7 h light/5 h dark-7 h light/5 h dark) could promote the plant height, total yield, and leaf quality of water dropwort.

Key words: plant factory, water dropwort, photoperiod, nutritional quality, microstructure
