Abstract

Hops production largely depends on daylength shortening for proper flowering. Innovative systems like indoor cultivation with LED lighting allow a precise control of photoperiod regardless of season. However, such systems are still under development for most crops and there isn’t a solid framework on which indoor hops cultivation can be referred to. The aim of this study is to provide a descriptive report on how hops plants can develop and flower in an indoor system. A growth chamber was designed to accommodate hops plants, providing lighting and two training methods: parallel and spiral. Within 90 days of vegetative growth the plants had substantially developed and photoperiod was reduced from 16 to 10 h. Flowering began 6 days after photoperiod shortening. Spiral training can provide a more ergonomic usage of vertical space, allowing hops plants to better develop length-wise. Although structural adjustments and further research are still needed, there is potential for hops production in an indoor system using LED lighting.

使用 LED 照明在室内系统中生产啤酒花是否有潜力？

啤酒花的生产在很大程度上依赖于日照时间的缩短来实现正常开花。采用LED照明的室内栽培等创新系统可以精确控制光周期，不受季节影响。然而，对于大多数作物来说，这种系统仍在开发之中，而且还没有一个坚实的框架可以作为室内啤酒花栽培的参考。本研究的目的是就啤酒花植物如何在室内系统中发育和开花提供一份描述性报告。我们设计了一个可容纳啤酒花植株的生长室，提供照明和两种培植方法：平行培植和螺旋培植。在无性生殖的 90 天内，植物已基本发育成熟，光周期从 16 小时缩短到 10 小时。螺旋式栽培可以更符合人体工程学地利用垂直空间，使啤酒花植株在长度上得到更好的发展。虽然仍需进行结构调整和进一步研究，但在使用 LED 照明的室内系统中生产啤酒花是有潜力的。
