<p>Apparatus for use in carrying out horticulture or agriculture in desert or the like areas includes a light-transmitting cover which can be extended over the soil to be cultivated and solar heating means, disposed outside the cover for heating a body of water during the daytime. At night, the heated water is circulated through conduits within the space under the cover to maintain a mild temperature beneath the cover, while said conduits may include exposed channels from which moisture may evaporate to condense on the covering and drop to the soil beneath the covering to water the growing plants. The apparatus may take the form of a vehicle which can be driven out to the selected area, with the light transmitting cover or covers packed or retracted and which, when the selected site has been reached, is stopped and the light transmitting cover or covers extended and the solar heating means displayed.</p> |
