The present invention relates to a container for growing conception in open field, and more specifically, to form a passage for bottom irrigation in the lower part of the buoyancy box, to form a drain and vent on the side, and to install a shading net on the top It is possible to grow a conception that can grow only in the half shade of the field. It is an object of the present invention to artificially cultivate the concept of growing only in a limited area, where the amount of wetland light is small, and to increase the added value by producing a conception that has grown to a uniform thickness. It is characterized by laying a moisturizing material on the bottom of the floating box with the bottom and side, and by supplying a box with the upper part, which is the growth part of conception, to the water to supply adequate amount of water steadily. In order to induce uniform growth, it is characterized in that the shading net of different density according to the season is fixed to each box, The close conception is supported on the side of the box, and prevents the falling of the water to prevent the corrosion of the previously grown portion is characterized by producing a high-quality conception of long length. By using the container for fertilization, the concept of growing only in the shade of wetlands can be cultivated in paddy fields, which replaces rice farming, which is avoided by overproduction and cost reduction, as well as import substitution effect. Floating water will reduce the cost of watering by placing an impregnated container on the water in the paddy field. The conception container floating in the water is effortless and easy to move in the plantation by simply pushing or pulling. Each conception cultivation container is easy to move so that it can be easily isolated when a pest occurs, and can prevent the spread of pests in advance. Seasonal shading can be used to export to overseas markets where long term quality fertility is preferred.본 고안은 노지에
