Jaarrond duurzame en intensieve aardbeienteelt met minder stroom : Deskstudie naar mogelijkheden besparing op elektriciteit
The opportunities to significantly reduce the electricity consumption in an illuminated strawberry cultivationhas been analysed in a desk study. Special energy-efficient LED lamps can be used to steer plant growth anddevelopment. By replacing HPS-lamps by the latest LEDs with an energy efficiency of 2.7 μmol/W, the powerconsumption can be reduced by more than 30%. It seems possible to reduce this consumption in illuminatedstrawberries by another 10% in a greenhouse with high light transmission in the winter months and usingartificial lighting more in relation to different growth stages. Light colour (spectrum) affects the growth,production and quality of strawberries. A high amount of red light stimulates production and blue light enhancesthe sugar and vitamin C content.The light and energy consumption can be further decreased by improved space utilization and by reducing theleaf/fruit ratio. Gas savings are possible by minimizing the use of the minimum heating pipe and closing theenergy screen during cold weather. However, this requires special attention with respect to the prevention offungal diseases and maintaining fruit quality.
