Abstract

This paper describes the contents of studies carried out for four years on a fluorescent lamp type vegetation plant. The equipment consists of a chiller unit with 5 HP, a motive power board of three-phase 200 V/feeder with an annual power capacity of 20 kW at maximum, and a micro-computer to control the culture environmental conditions. Discussions were given on the equipment performance, profitability, production capacity for salads and lettuces, and related data. Although the system has some disadvantage in the economy, it provided effective results on the know-hows in culturing high-class vegetables and fruits under season-free and chemical-free conditions. Since the natural light is also required, the professional knowledges and know-hows in this area were incorporated in the development. Fluorescent lamps emitting three primary colors of red, green and blue were devised and used. Because insufficient light intensity would raise the temperature only up to 42{degree}C when the ambient temperature is 25{degree}C, a proximity illumination system was adopted, which provided 45KIx high light intensity as well as the working spectra over an wide area. Tomato cultivation has also become possible, which is an epoch-making success. The system yielded better than hydroponic cultivation in solar greenhouse of the same size.  More>>
