GREENHOUSE CULTIVATION METHOD FOR CROPS AND CULTIVATION EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To provide a greenhouse cultivation method for crops and cultivation equipment which increases crop yield by heating the soil planted with crops and to promote the growth of crops by irradiation of far infrared rays from far infrared radiators arranged on both sides along planted ridges.SOLUTION: The greenhouse cultivation method for crops and the cultivation equipment is provided such that in the soil inside the greenhouse, a heat medium liquid is circulated through a pipe buried at a depth of 40 cm to 80 cm from the surface of the earth to raise the temperature of the greenhouse soil at the time of cold. A tube made of a good thermal conductor for circulating the heat medium clad with a ceramic tube or a ceramic powder layer to form a far-infrared radiator or a far infrared radiator having a heating wire inserted in a ceramic tube is disposed on both sides of a ridge along which crops are planted and the crops are directly irradiated by far infrared rays.SELECTED DRAWING: Figure 1
