Duurzame teeltsystemen met LEDs

Abstract

To combine the development towards sustainable and climate-neutral cultivation systems for all-electric greenhouses with lighting, efficient lighting systems such as LEDs are essential. LEDs have a high energy-efficiency and make it possible to apply dynamic light recipes, in which light intensity and spectral composition can be varied throughout the day and during the cultivation depending on the developmental stage of the crop. Knowledge on the effects of light spectrum is still limited for most crops, as well as the effect of spectral composition on the control of pests and diseases in the crop. In this project, we took an integrated approach that combines research on the effects of dynamic light spectra on the growth and production of eggplant, tomatoes and cucumbers with the effects on plant resistance to pests and diseases, incorporating the underlying physiological and genetic processes. The behavior of pests and natural enemies has been further investigated in chrysanthemum and sweet pepper. The results indicate that growth and production of greenhouse grown crops can be controlled with the light spectrum, whereby resistance to diseases and pests is a precondition.
