CEMENT BLOCK WALL CULTIVATION OF STRAWBERRY IN JAPAN
A unique growing system of strawberry forcing-culture using solar heating is Shizuoka Prefecture in Japan. It was developed by growers and has been in practice since 1910. In this system, fabricated cement block fences are stacked on a hillside slope and covered with large plastic tunnels to retain the heat during the night. The number of hectares of cement block wall cultivation was highest at 80 ha in 1939. At present the cement block wall cultivation is 60 ha and is not a significant production system nationally. It is primarily used for pick-you-own sales to tourists visiting the region. Measurements were made of CO2 concentration and temperature distribution of canopies under plastic tunnels.
