[Korean Farmers' News Reporter Jo Sung-je] Gumi City has confirmed through empirical research that LED supplementary lighting can improve productivity in multi-layer strawberry cultivation. In this regard, the Gumi Agricultural Technology Center recently announced the results of the "Test Research on Changes in Strawberry Growth According to LED Light Source and Installation Conditions" conducted in a smart testbed house last year. According to the Gumi Agricultural Technology Center, this test research is significant as it is an empirical study aimed at improving the problem of insufficient sunlight in the lower bed, a structural limitation of multi-layer (two-layer) strawberry cultivation, and it also analyzes the possibility of applying it to actual farms. Multi-layer strawberry cultivation has the advantage of increasing production from the same area.
