1. A plastic house in which strawberries were grown was subjected to the present investigation. It was of an east-west orientation, composed of four bamboo-supported unit houses interconnected side by side. The house was built on a slope inclined at an angle of 35°. The total area it covered was about 200m2. Measurements were carried out chiefly for temperature and air circulation in the house from the 28th to the 30th of January, 1966.
2. At noon (from 11.00 to 14.00) on a fine day, the highest temperature in the house was 34.2°C in the third unit house. At night (from 22.00 to 5.30) the lower the location of the unit house was, the lower the temperature. There was an ascending air stream over the stone-wall during day and night, which caused the difference of temperature among the unit houses.
3. It seemed quite possible that the difference of temperature had a considerable influence on the growth and production of strawberries in the house.
