Description of the Related Art Conventionally, seedling containers of various shapes have been used to grow soil-grown seedlings used for transplanting vegetables, flowers, paddy rice, etc. After the soil-grown seedlings have been grown, they can be transplanted by a transplanter or manually. It is being transplanted to this field. Transplanting with soil-based seedlings such as these has less root damage and good survival, and does not handle the plant itself at the time of transplantation. It makes it possible easily and brings about the effects such as labor saving. And for raising seedlings with soil such as a seedling raising box, a seedling raising paper cylinder collecting pot, or a seedling raising container such as a synthetic resin frame, conventionally used seedling culture medium is At the time of work, it is used by mixing fertilizer with ordinary soil and adjusting it, and the root pot part used as a handling part for sandwich transportation etc. in transplanting work has been strengthened. However, the root pot portion is easily broken or chipped during the transplanting work, which lowers the efficiency of the transplanting work and causes growth failure after the transplantation. Furthermore, a transplanted seedling lacking a root pot part cannot be mechanically planted, and thus a missing plant is also generated. In addition, soil-grown seedlings are easily crumbled even when transplanting by hand planting work because the root pot part is grasped by hand, especially when the seedling raising period is short and the rooting is insufficient, When using a large diameter pot,
The root pot part is likely to collapse and requires careful handling.

As disclosed in Japanese Patent No. 236416, by adding and mixing a polyethylene oxide polymer in a nursery medium in an amount of 0.1 to 1.5% by weight, without inhibiting the growth of seedlings during nursery,
We proposed a method for preparing a medium that is highly unity and suitable for mechanical transplantation while maintaining air permeability during transplantation.

る。However, in recent years, in order to save the labor and complexity of adjusting the medium one by one at the start of the seedling raising work, it is required that the seedling raising container can be filled with the adjusted medium immediately after the start of the seedling raising work. In this case, the medium should have an appropriate water content of 25% to prevent dust generation and work.
It is desirable to have ˜40%. That is, if the water content is low, the medium becomes a dry medium and dust rises, and if the water content is high, it becomes a muddy state, which makes the handling difficult and the workability deteriorates. And in the case of the method for adjusting the adjusted medium in which the polyethylene oxide polymer powder is added and mixed, the adjustment is performed immediately before use, and the water content in the medium is 20% by weight or less. Polyethylene oxide polymer powder that is extremely prone to dust rising during use and has a high hygroscopicity and a strong cohesion, and exhibits elasticity and cohesion when the water content is 25 to 40% by weight for dust prevention. Absorbs water in the medium during storage and becomes a dumpling state. Not only does it hinder the uniform dispersion of the medium when filling the seedling-growing container, but it also impairs the effect aimed at making the entire soiled part a good solidified body at the time of transplantation, and in all operations from seedling to transplantation. It will worsen the handling.

である。In order to solve the above-mentioned deficiencies, the present inventor has further added the polyethylene oxide polymer powder mixed medium of JP-A-62-236416 as a medium for soil-implanted seedlings suitable for mechanical transplantation. Even after long-term storage, the polyethylene oxide polymer powder does not form a lump by the water content of the medium, and even when the medium is filled at the start of the nursery work, it can be easily filled into the seedling-growing container while maintaining the smooth state as at the beginning of storage. And, as a result of diligent research on the conditions for solidifying the soil portion by sequentially melting it by irrigation during seedling raising, as a means to measure homogenous dispersion in the medium, mineral porous material was dissolved in water such as polyethylene oxide polymer. After adding a binding agent, the mineral porous substance is uniformly dispersed and mixed in a medium containing a specified amount of water, so that the water content of the medium during storage is water-soluble. There does not melt, the medium can be an adjustment medium without dumpling state of, is obtained by the modifier. That is,
When this adjusting agent is uniformly mixed in the medium, the water-soluble binder impregnated in the pores of the mineral substance has a water content of 25% in the medium.
The present invention has been achieved by discovering that even if the amount is up to 40% by weight, it does not dissolve, and that when seedling containers are filled with a medium and seeded, and then irrigation is started under seedling-raising conditions, the water gradually leaks.

容器への充填の均一性について比較した。The present inventor used polyethylene oxide polymer powder as the water-soluble binder and used ceramics obtained by firing diatomaceous earth having a large number of fine pores at a high temperature as the mineral porous material. Adsorption is ceramic (bulk specific gravity: 0.
5% by volume of a 10% aqueous solution of polyethylene oxide polymer was adsorbed on 5), and dehydration drying treatment was performed. The attachment ratio of the water-soluble binder to the mineral porous material was about 9% by weight. Mineral porous material 1 with this water-soluble binder attached
10 parts by volume of normal seedling-growing medium mixed with parts by volume and fertilizer is uniformly mixed, and the water content is increased from 15% to 40% in 5% increments.
Each of the adjusted media (A) was prepared and put in a polyethylene bag and stored for 90 days. As a control, polyethylene oxide polymer powder was directly added to a normal medium mixed with fertilizer at 0.5% by weight in the same concentration as above to form a medium (B), which was made into a state of dumpling, generation of dust, and a container for raising seedlings. Comparison was made regarding the uniformity of filling.

る。。As shown in Table 1 above, in the conditioned medium in which the polyethylene oxide polymer powder is simply added to the medium, even if the water content is about 15%, if this is stored, it will absorb the water in the medium. It becomes a dumpling and there is a lot of dust generation. When the water content is 20% or more, dumpling becomes extremely large, and it becomes impossible to fill the seedling-growing container in a uniform state. On the other hand, in the conditioned medium in which the polyethylene oxide polymer was adsorbed on the ceramic and then uniformly mixed with the medium, the lumping phenomenon did not occur even when the water content was 40% by weight, and it showed a very smooth state and showed no dust. There is no occurrence, and the seedling raising container can be filled uniformly. .
