Description

Bed control device and method for raising seedlings using subsurface irrigation {Apparatus and method for controlling a seedling bed using subsurface irrigation}

The present invention relates to a seedling bed control device using subsurface irrigation and a method thereof, and in detail, to a device for performing bottom irrigation by automatically moving a seedling bed up and down, and a device thereof It's about how.

Head irrigation is a method in which a person directly sprays water from the top of the crop using a hose or a water sprinkler, and it has the disadvantage that it takes a very long time to give water. For example, in the case of head irrigation in a 6-meter-wide and 50-meter-long plantation facility, it may take more than 30 minutes to adequately supply moisture to the seedling beds (or trays) or differentiation beds. . In addition, head irrigation is difficult to evenly supply water as a whole because people have to check it with their own eyes and give water. In addition, spores of fungal pathogens such as powdery mildew spread well in the water sprayed from above, so that the spread of the disease can be easily achieved.

In order to overcome the problems caused by the water current, an automatic sprinkler system is used that sprays water in the form of mist through the irrigation facility at the top using a sprinkler, fountain hose, etc., but the system also has many problems. In the case of general soil (a form of planting and growing crops by plowing the ground), the system can be a very convenient irrigation system because water permeates into the ground and spreads out as a whole when water is sprinkled appropriately. However, in the case of seedling or differentiated cultivation, water must be sprayed evenly over the entire cultivation area. Unlike the soil that permeates into the ground and spreads, if the water falling from the top does not fall into the tray area or pot with crops, there will be a problem of not irrigation. can No matter how well it is controlled and a mist generator with good performance is used, there is bound to be an area where the mist does not reach, and in this case, it is necessary to monitor the area where the mist does not reach through an assistant. Also, even if the irrigation system is well-adjusted to spread the water throughout, if the crop is rather tall and leafy, the bottom will be covered by the leaves, making it more difficult to distribute dripping water throughout. Falling of crops also occurs frequently. Therefore, most sprinkler systems are used until the early stage of growth, and during the growing season, when a large amount of water is required, watering is carried out while being careful not to fall between the leaves directly by human hands.

As an alternative to this limitation, low-level irrigation that waters from the lower surface of the soil can supply water evenly throughout, and there is no reason to water or send water to the upper crops, so the spread of the disease is significantly reduced, and the crops that are growing By irrigation without applying force to the crop, it is possible to provide conditions for crops to grow straight stems without stress.

In relation to this, conventional Korean Patent Registration No. 10-1910493 (submerged irrigation nursery facility, 2018. 10. 29) is the most important to enable the uniform growth of seedlings in a nursery for mass-nurturing various seedlings. The water supply, which is a factor, can be uniformly supplied by the immersion irrigation method, and residual water can be removed, so that freezing accidents can be prevented even in winter, and the port movement between the nursery and the work area can be saved. Provides a bottom irrigation type nursery facility. However, this does not disclose a means for providing ventilation of seedlings that is absolutely necessary after irrigation, and when the prior art is applied, inconvenience arises in that remaining water must be drained every time irrigation is performed to provide ventilation. After draining it, it has a limitation that a separate space is required to store it. In addition, the limitation that it is difficult to control the time when the seedlings are immersed and the conventional registered patent publication in which the remaining water is filled to a certain level and then drained is a limitation that the larger the scale of the nursery, the more time is consumed to receive water and excessive water is consumed. there is
