APPLICATIONS OF ELECTRICITY IN JAPANESE HORTICULTURE

This report deals with a review of the uses of electric power in Japanese horticulture, and gives three examples of new installations which are now used practically or studied through laboratory research.

1. The seed incubator. This consists of a frame, cover, and an inside tray.
   An electric heater is installed on the bottom and controls the inside temperature with a thermostat.

2. The pellet house. This consists of a roof and side walls protected with double glass or plastics film.
   Expended polystyrene pellets are stored between the glass or plastics film with an exhaust blower.
   During the night they are distributed for heat insulation and in the daytime returned to pellet tanks underground or at the side of the house.

3. The earth-air heat exchange house. Pipes are mounted underground and used to circulate air from under the earth in order to utilize earth-air heat exchange for heating in winter and for cooling in the daytime in summer.
