This project addresses maximising fruit yield and through optimising the light recipe quality, focusing on strawberry. It aligns closely with the following pillars of the industrial strategy: (1) investing in science, research and innovation, and (2) developing skills. If successful, the wider insights on LED crop light responses could be generalised to other crops grown in greenhouse or vertically-farmed farm crops, however by focussing on strawberry we are addressing one of most valuable fruit crops in the UK. The strawberry market within the UK continues to grow but we are importing an increasing volume (£120M) of fruit during the winter months. The UK has an opportunity to produce greater volumes of fruit during the winter, but this requires glasshouse technology combined with modern supplementary lighting systems. There is an on-going interest in the application of LED lighting systems in modern glasshouse as these provide an energy efficiency gain of ca. 30% over conventional high-pressure sodium systems. They also offer opportunities to provide highly defined spectral outputs to maximise productivity. However, as yet these opportunities have yet to be realised. We do not understand the optimal spectral qualities for any crop let alone strawberries, how this change through production and how they impact the key drivers (photosynthesis / radiation capture / partitioning etc) of yield and quality. This PhD will examine these issues and develop optimal strategies for the use of LED lighting in soft fruit production.

该项目旨在通过优化轻配方质量，最大限度地提高水果产量，重点是草莓。它与工业战略的以下支柱密切相关：(1)投资于科学、研究和创新；(2)发展技能。如果成功，关于LED作物光响应的更广泛的见解可以推广到温室或垂直种植的农作物中，但是通过关注草莓，我们正在解决英国最有价值的水果作物之一。英国的草莓市场持续增长，但我们在冬季的进口量也在增加（1.2亿英镑）。英国有机会在冬季生产更多的水果，但这需要温室技术与现代辅助照明系统相结合。人们对LED照明系统在现代温室中的应用一直很感兴趣，因为它们比传统的高压钠灯系统提供了大约30%的能源效率增益。它们还提供了提供高清晰度频谱输出的机会，以最大限度地提高生产率。然而，到目前为止，这些机会尚未实现。我们不了解任何作物的最佳光谱品质，更不用说草莓了，也不了解这种品质在生产过程中是如何变化的，以及它们如何影响产量和质量的关键驱动因素（光合作用/辐射捕获/分配等）。本博士将研究这些问题，并制定在软果生产中使用LED照明的最佳策略。
