Abstract

PROBLEM TO BE SOLVED: To solve the problem that the conventional structure in which air ducts and/or blowout ducts are used to send CO2, warm air, or the like toward growing points of plants does not employ a circulation system which controls hot air present in areas near the roof of the greenhouse; this means that the conventional structure is not sufficient in obtaining an air environment suitable for improvement of yield and quality by sending the hot air toward growing points of plants or in making use of the hot air for growth of plants (crop plants).SOLUTION: The air ventilation system according to the present invention is used for a greenhouse cultivation method including air supply means which blows out air or warm air in the greenhouse, for example, using an air blower and ducts suspended down from a beam, toward areas near the ground surface in the greenhouse or toward growing points of shelf-cultivated plants in the green house. The present invention proposes a circulation system which controls the hot air present in the areas near the roof of the greenhouse to enable achievement of an air environment optimized for growth of plants by sending hot air or cool air in the upper areas of the greenhouse toward growing points such as flower buds and stems of plants.

  The embodiment of the present invention will be described. Reference numeral 1 denotes a house. For example, in the transverse direction X of the house 1, the suspension means of the house 1, such as a beam 2 (land beam), a support material, etc. One to a plurality of blowers 4 and one to a plurality of ducts 5 are suspended through a support member 3 made of one to a plurality of hooks and strings or wires. Although not shown, the duct 5 has a structure that can be expanded and contracted or moved up and down by an appropriate means. Further, the duct 5 is provided with a branch duct 50 attached in the longitudinal direction Y (ridge direction) of the house 1. The method of supporting the duct 5 and the blower 4 or the like to the house 1 is an example. Moreover, as a moving means of the duct 5, for example, raising / lowering / extending / contracting of a vertically moving base, a link mechanism, or a string can be considered.

  The blower 4 covers a wind tunnel 400, a ceiling cover 401 provided at an interval to the wind tunnel 400, a fan 402 provided on the top of the wind tunnel 400, a motor for driving a fan 402 (not shown), and the fan 402. The wind tunnel 400 and the ceiling cover 401 are connected to each other by a guard 403 formed of a net. The fan 402 rotates to introduce air into the wind tunnel 400. And, the duct 5 is supported in the lower opening of the wind tunnel 400, and hot air introduced into the wind tunnel 400 or carbon dioxide (in the outside air or not shown, carbon dioxide is generated, not shown). From the machine), outside air, or hot air from the heater (not shown) or the like is sent to the duct 5.

  Reference numeral 6 denotes a support means composed of a string used in the hanging gutter system suspended from the beam 2 or a wire 600, a pulley 601 and the like. This support means 6 is also applied to another beam 2a provided in the longitudinal direction Y. It is suspended. Therefore, the cultivation bed 7 (shelf) is supported by the pair of support means 6 and 6. Moreover, in this example, the duct 5 is suspended at one end in the longitudinal direction Y of the cultivated floor 7 (one cultivated floor 7a or a gap in the middle, and one or many of the floors of the duct 5 or between the stocks. The two branch ducts 50, 50... (50) are provided, and each branch duct 50 (referred to as the branch duct 50) is provided at the other end in the longitudinal direction Y of the cultivation floor 7 (the other cultivation floor 7b). For example, in the example shown in Fig. 1, the branch duct 50 is installed for each cultivation floor 7 (cultivation shelf), and therefore, from the bottom of the shelf, the pores 5000 of the branch duct 50, which will be described later, and the pores. Using the directionality of 5000, warm air is sent in a concentrated manner from the root of the plant A toward the leaves of each stage and / or each growth point A1 or the vicinity of each growth point. In the example shown in FIG. 3, the narrow branch duct 50 is arranged between the communities of the plant A. The strains), and the deployment number, through the pores 5000, the growing points of the plant A A1, or near the growing point, toward sequentially respectively, and sends the hot air or the like.

  In the figure, H is a high temperature sensor, L is a low temperature sensor, the high temperature sensor H is an upper part of the house 1 or a region away from the growth point A1, and the low temperature sensor L is a plant A. One to several groups are provided in the vicinity of the growth point A1 or the growth point A1. Intended to match the growth of plant A.

  4a in the figure shows a circulation fan suspended from the house 1, and the air in the house 1 is agitated.

  Next, with reference to the example shown in the flowcharts of FIGS. 1 to 3 and FIG. 6, the operation of the blower 4 and the flow of the wind will be described. On the contrary, in the state where the cultivation floor 7 becomes low temperature air, for example, when the detected value of the high place temperature sensor H is higher than the detected value of the low place temperature sensor L, the fan 4 is operated, Hot air is taken into the duct 5, and this hot air is blown through the branch duct 50 between the plants A and / or to the growth point A1. Thereby, the growth point A1 is beneficial to growth promotion and the growth of flower buds by receiving the benefits of high-temperature air. In addition, the operation of the blower 4 is stopped in a state where the temperature of the growth point A1 is suitable for the growth promotion and the growth of flower buds due to the blowing of high-temperature air. This operation is performed, and hot air is blown in sequence toward the one cultivation bed 7a and the other cultivation floor 7b when necessary. That is, in FIG. 3, the air flows smoothly, surely and smoothly in the same direction toward the one cultivation floor 7 a and the other cultivation floor 7 b. As a result, as shown in FIG. 2, the flow of air such as high-temperature air in the longitudinal direction Y, air containing carbon dioxide, or outside air is obtained. Ensure proper air flow against plant growth points, etc., stimulate plant tolerance, improve growth, improve sugar content, improve bacterial resistance, improve yield, etc. Can contribute.
