In recent years greenhouse climatology has become a special branch of research in agricultural meteorology. The results of climatological investigations in greenhouses should indicate to the agriculturalist the meteorological conditions at his disposal for the cultivation of certain crops at any lime of the year, and the possibilities of using special techniques for controlling the growth of plants. The greenhouse gives him the opportunity of creating the proper conditions for the plants irrespective of the outside weather, and this provides the farmer/gardener with an all-the-year-round means of production. The first part of this Technical Note discusses the heat and moisture balances of the air and soil in naturally heated greenhouses and the effects of the diurnal and seasonal changes on the microclimate. Illustrative comparisons are made between meteorological conditions inside and outside the greenhouse. The second part reviews in detail the methods and techniques used for the control of greenhouse climates, and the various types of installations that are available for this purpose. The regulation of lighting and temperature, the methods of shading and ventilation, and the effects of water-spraying are explained in detail. An extensive classified bibliography is included and the text is illustrated with diagrams and tables.
