Problems solved by technology
As a result, the soil beneath the seedling boxes is contaminated with washed-out agrochemicals
This presents a problem for farmers who wish to plant other crops immediately after transplanting rice seedlings where the seedling boxes were placed: namely, since many pesticides are only suitable for rice, this does not allow farmers to plant other crops in the contaminated area
In this case, it is better for farmers to wait for a while until the agrochemicals degrade, however, this will definitely bring financial losses
[0006] Another problem is that soil-borne diseases, such as soil-borne fungi or bacteria, that arise in the soil where the box is placed can migrate into the box through the bottom opening and infect the growth medium and / or the seeds or seedlings
[0007] Also, agrochemicals are wasted due to spillage

Embodiment Construction
[0038] The figure schematically shows a rice seedling box with a rectangular bottom shape (plan view) without openings in the bottom, and on the side walls a hypothetical layer containing granular agrochemicals or a hypothetical layer containing agrochemicals The base layer has an opening (1) at a position closely above the upper limit (2) and an opening / closing opening (3) near the bottom.
[0039] The number and position of the openings (1) in the side walls should not be understood as being limited to what is shown in the figures. Instead the openings may be distributed over all four walls. The shape of the opening should also not be construed as limited to the shape shown in the figures, but any suitable form can be adopted.

The present invention relates to a seedling box having openings for the drainage of surplus irrigation water on at least one side wall of the box. The invention further relates to the use of such a seedling box for growing young plants, especially young rice plants, and to method for growing young plants, especially young rice plants, which method comprises sowing seeds, specifically rice seeds, into or onto a growth medium contained in such a seedling box and growing the plants in this box until they reach a predetermined size.
Description
technical field [0001] The present invention relates to a seedling box having an opening for draining excess irrigation water on at least one side wall of the box. The present invention also relates to the application of the seedling box in cultivating seedlings, especially rice seedlings, and a method for cultivating seedlings, especially rice seedlings. The method comprises sowing seeds, particularly rice seeds, in or on a growth medium contained in such a seedling box, and growing the plants in the box until they grow to a predetermined size . Background technique [0002] Sowing rice seeds and growing seedlings in seedling boxes (also called seedling boxes) is a common way of growing rice, especially in Japan. Seedling boxes are generally placed in a greenhouse or protected location until the seedlings reach a specific height. Then, the seedlings are transplanted, for example, into rice fields. [0003] A typical rice seedling box is a rectangular container or tray a...
