Description

[Detailed Description of the Invention] [Industrial field of application] The present invention provides a plurality of trolleys in which seedling raising boxes are stacked in a plurality of upper and lower stages in a nursery house, and each of the seedlings in the trolleys arranged in the plurality. The present invention relates to a watering device for watering a box.

[Conventional technology]

Conventionally, there has been an irrigation device as disclosed in JP-A-62-143615. In other words, the trolleys loaded with the nursery boxes in the upper and lower tiers are arranged in front of and behind the nursery house,
Each of the carriages is provided with a sprinkling nozzle for sprinkling water from at least the left and right sides of the aligned carriages to the seedling raising boxes in each stage of the carriage, and the sprinkling nozzles move in the front-rear row direction on the left and right sides of the aligned carriages. There used to be a watering device for watering the nursery boxes.

[Problems to be solved by the invention]

After sowing seedlings in a nursery box, the seedlings are germinated in a stacked state, and there are several stages above and below the shelves inside the trolley, and the nursery boxes are loaded at predetermined intervals to plant trees. When irrigating the nursery boxes at each stage, irrigation can be carried out efficiently by using the conventional device.

However, as a result of irrigation by actually using the above-mentioned conventional apparatus in the above-mentioned seedling raising facility, it became clear that the following growth problems occurred.

That is, when raising and lowering multiple stages of seedlings in the trolley and raising the seedlings in the nursery house, the uppermost stage of the trolley in the trolley and the stages of seedlings below each stage are exposed to sunlight and ventilation. Therefore, the amount of water transpiration in the uppermost nursery box is larger than that in the lower nursery box. It was easier to dry than a nursery box. In addition, since the nursery boxes are stacked in multiple stages in the trolley, water will drip from the nursery boxes placed on the upper side after the sprinkler has finished sprinkling, and it will reach the lower nursery boxes. From this point as well,
The uppermost nursery box was easier to dry than the lower nursery box.

Therefore, when irrigation is required in the uppermost nursery box, the lower nursery box is still in a state where irrigation is not necessary. The roots of the seedlings in the nursery box do not easily grow and the rooting becomes poor. Also, in the lower nursery box, irrigation must be done until it has dried to the required state,
The seedlings in the top row are too dry and the seedlings die. Therefore, in the conventional irrigation system, it was not possible to irrigate both the uppermost seedling raising box and the lower seedling raising box so that the seedlings would grow well.

[Means for solving the problem]

In order to solve the above-mentioned problems, the present invention arranges a plurality of trolleys loaded with seedling raising boxes in the upper and lower stages in a row in the front and rear of the pedestrian in a nursery house, and at least from the left and right sides of the aligned trolleys, In the irrigation device, which is equipped with a watering nozzle for watering the seedling raising box in each stage, and which moves in the front-rear row direction on the left and right sides of the carriage in which the watering nozzles are aligned, watering the seedling raising box in each carriage, the uppermost stage in the carriage The amount of water sprayed to the nursery box
The irrigation device is characterized in that a large amount of water is sprinkled with respect to the amount of water sprinkled to the seedling raising boxes at each stage below the uppermost seedling raising box.

〔The invention's effect〕

The irrigation system of the present invention has a plurality of trolleys loaded with nursery boxes in a plurality of upper and lower rows aligned in the front and back of a plurality of tiers in a nursery house, and from at least both the left and right sides of the aligned trolleys to the respective tiers in the trolley. Since the watering device is provided with a watering nozzle for watering, and the watering nozzles move in the front-rear row direction on the left and right sides of the carriage on which the watering nozzles are arranged in an array, watering the seedling raising boxes in each carriage efficiently it can.

Moreover, since the watering amount to the uppermost seedling raising box in the trolley is a sprinkler that sprinkles more water than the amount of watering to the lower raising seedling raising boxes at each stage, While making it possible to irrigate efficiently, both the uppermost nursery box and the lower nursery box can be irrigated so that the seedlings can grow well, and a large number of good seedlings can be grown efficiently. it can.
