Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cultivation management device for preventing overgrowth of a cultivated crop so that the crop grows healthy.

[0002]

[Prior art]

 For example, there is a contact stimulating means for contacting a leaf or vegetable brush or cloth with the seedling leaf as one of the methods for preventing overgrowth at the time of raising seedlings, which has reached the range of practical application.

[0003]

[Problems to be solved by the device]

 However, if such contact stimuli are used to prevent overgrowth, contact stimuli with a brush or cloth from above are not practical for seedlings whose growth points are lower than the leaves, and air contact stimuli are considered. However, in this case, there was a problem that it was difficult to realize from a profitability point of view because a device dedicated to air was required.

[0004]

[Means for Solving the Problems]

 Therefore, the present invention provides a spraying nozzle for spraying liquid or air such as water or liquid fertilizer on a cultivated crop, and spraying water or liquid manure etc. by preventing overgrowth of the crop by contact stimulation of these liquid and air. Injecting air into the existing irrigation system Work that effectively uses the existing facility that has the injection nozzle device installed, or effectively uses the existing facility that also uses the irrigation pipe of the existing irrigation system as the air injection nozzle. The seedlings targeted for contact stimulation are expanded by extremely economical means, such as by enabling all the work to promote healthy seedling growth.

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Fig. 1 is an illustration of irrigation and air pipelines, Fig. 2 is an illustration of a nursery house, where (1) is a nursery house and (2) is a two-row nursery bed in which a large number of nursery boxes (3) are arranged. , (4) is a movable frame that reciprocally supports the guide rails (5) (6) installed on the center of the ceiling of the nursery house (1) and on both sides thereof via rollers (7) (8), (9a). (9b) is a cultivated crop (3) of the seedling box (3), which is supported by the movable frame (4) through the support arms (10a) and (10b) and the adjusting bolts (10c) so that its height can be adjusted. ) Is a two-row jet nozzle that jets liquid and liquid such as water or liquid fertilizer from above, and when the nozzles (9a) and (9b) are moved back and forth on the nursery bed (2), the liquid from the jet hole (11) Alternatively, the air is sprayed onto the seedling (A).

Then, the ejection nozzles (9a) and (9b) are powered by the electromagnetic spray valves (12a) and (12b) and the three-way electromagnetic first switching valve (13) through the power sprayer (14) and the air compressor (15). ), And the water absorption side of the sprayer (14) is connected to the dilution tank (17) and the raw water tank (18) via the three-way electromagnetic second switching valve (16). A pipe for connecting the dilution tank (17) to the concentrate tank (20) via the pump-incorporated mixer (19) and to the raw water tank (18) via the flow meter (21) and the raw water pump (22). When connected, the nozzles (9a) (9b) inject either air from the compressor (15), water from the sprayer (14), or liquid fertilizer with a set concentration from the dilution tank (17). It is configured to let.

The jet nozzles (9a) and (9b) are mainly used to spray air, water or liquid fertilizer on the growing points (stem tips, root tips) of seedlings to stimulate the growing points and prevent overgrowth of crops. The injection pressure can be adjusted according to the growing condition of the seedlings.

As shown in FIG. 3, a control circuit (23) for controlling the injection work is provided, and an irrigation switch (24) for selecting the irrigation work of water or liquid fertilizer and selection of the air injection work. An air injection switch (25) for performing the above operation, a nozzle opening / closing switch (26a) (26b) for opening / closing the nozzle opening / closing valve (12a) (12b), the above-mentioned flow meter (21), and the dilution tank (17). The control circuit (23) is connected to a level sensor (27) for detecting the amount of liquid fertilizer in (), and the sprayer (14), the compressor (15), and the nozzle opening / closing valve (12a) ( 12b), the switching valves (13) (16), the mixing device (19), and the raw water pump (22) are connected to the control circuit (23) by output connection, and the switches (24) (25) are connected. ) (26a) (26b) While each injection work of the nozzles (9a) and (9b) is performed, when the amount of liquid fertilizer in the dilution tank (17) is below a certain level, the concentrated liquid tank (20) is adjusted according to the amount of water detected by the flow meter (21). The nutrient solution from (1) is mixed through the mixing device (19) so that a fixed amount of liquid fertilizer is always stored in the tank (17).

The present embodiment is configured as described above, and the contact stimulus by air injection is frequently (10 times or more / day) for irrigation work of water or liquid fertilizer, as shown in FIG. During the watering operation, the switching valve (13) is switched to the sprayer (14) side, and the switching valve (16) is switched to the raw water tank (18) or the dilution tank (17) side depending on the liquid condition of water or liquid fertilizer. When the sprayer (14) is switched to start the movement of the nozzles (9a) (9b), both or either one of the required nozzle opening / closing valves (12a) (12b) is opened, When water or liquid fertilizer is injected to the seedling (A), while the switching valve (13) is switched to the compressor (15) side to drive the compressor (15), the nozzles (9a) and (9b) predetermined By injecting pressure air to the seedling (A) This is to prevent this overgrowth by stimulating the growing point of the seedling (A).

In this embodiment, one nozzle (9a) and (9b) are used for both irrigation and air injection, but it is also possible to provide each nozzle for irrigation and air injection. Instead of the crane system such as the moving frame (4) that moves the roofs (9a) and (9b) on the ceiling, it may be mounted on a robot vehicle that runs unmanned on the ground.

FIG. 5 to FIG. 7 show an example of a structure in which the length of the brush is prevented by the contact stimulus of the brush. A polyethylene rotating brush (28) for contacting the leaf surface of the seedling (A) is provided and the brush is provided. A moving frame (29) supporting (28) is provided with a brush rotation drive motor (31) for rotating the brush (28) via a belt (30), and a bed (2) is guided by a guide rail (32). The guide roller (33) for laterally moving the brush (28) along the upper seedling (A), and the brush lateral movement drive motor (34) for rotating one of the guide rollers (33) are connected to the frame (29). ), The brush (28) is brought into contact with the leaf surface of the seedling (A), and when the brush (28) is rotated to move laterally, the whole seedling (A) is stimulated from above the head. By As shown in the measurement data of seedlings (A) with 30 days of raising seedlings in Fig. 7, the number of leaves (actual leaves (a), cotyledons (b), etc.) in the contact stimulation area with this brush (28) is larger than that in the untreated area. The plant length (L) and the hypocotyl length of the hypocotyl (c) are also configured to prevent overgrowth of the seedling (A).

FIG. 8 shows another modified structure example of the injection nozzles (9a) and (9b). The nozzles (9a) and (9b) are connected to the sprayer (14) and the compressor (15) by pipes. A directional electromagnetic switch valve (35a) (35b) is provided therein, and when irrigation is performed by one nozzle (9a) or (9b) of the two rows of injection nozzles (9a) (9b), the other The nozzle (9b) or (9a) is configured to enable air injection.

Further, in the above-described embodiment, the configuration is shown in which the injection nozzles (9a) and (9b) are provided in two rows on the left and right with respect to the movement direction, but they may be provided in a state where they are overlapped in two rows in the front and rear with respect to the movement direction. .
