Environmental control of greenhouse and plastic cover. II

Engei Gakkai zasshi, 1967
1. Climatic factors were measured in large gutter-connected greenhouses which are equipped with the cooling system as pad-and fan in Kusatsu City of Shiga Prefecture.2. The greenhouses measured were so different from one another in their structures, aeration systems and crops, that the temperature and wind velocity were studied for three to four ...
