Fruit and vegetable cultivation facility and tomato cultivation method in the cultivation facility

摘要

PROBLEM TO BE SOLVED: To provide a means for enabling cold-clamping cultivation of fruit vegetables such as tomatoes, which are preferred to have a high sugar content in a high temperature period, in cultivated soil. SOLUTION: A cultivation facility S for fruit vegetables such as tomatoes is provided with a cultivation area 2, a roof for blocking rainfall on the cultivation area 2, and a cultivation area cooling device 4 for cooling the cultivation area 2. The cultivated land 2 is composed of a heat insulating material 6 arranged on the side surface and the bottom surface of a recess formed on the ground, a cultivated soil 3 housed in a container-shaped space defined by the heat insulating material 6, and a cultivated soil 3. It has a rice husk layer 10 placed on the upper surface. The cultivation area cooling device 4 includes a heat transfer tube 13 buried in the cultivation soil 3 and a cold water supply device 14 that supplies cold water at 0 to 10 ° C. to the hollow portion of the heat transfer tube 13. The chilled water supply device 14 includes a chilled water storage tank 15, a chilled water supply pipe 16, a chilled water reflux pipe 17, a pump 18, a refrigerator 19, and a chilled water tower 20.
