Abstract

PURPOSE:To prepare a mat-shaped seedling having a layer of fertilizer coated with a water-soluble coating agent on a mat-shaped bed, capable of dividing the mat-shaped bed without dropping the fertilizer thereon and transplanting the seedling, enabling advanced performing of post-transplantation fertilizing at the same time of sowing and excellent in laborsaving. CONSTITUTION:For example, culture soil prepared by compounding fertilizers necessary for seedling growing followed by mixing the fertilizers with soil is packed in a state of a layer as a bottom soil 2 in the seedling-growing box 1. Coated fertilizer 5 prepared by coating fertilizers mainly containing N, O and K with a water-soluble coating agent is packed in a state of a layer on the bottom soil 2. Further, the same culture soil as the culture soil 2 is laid on the layer of the coated fertilizer in a state of a layer as middle soil 6. Unhulled seeds 7 are sowed on the middle soil 6 and finally these are covered with the same culture soil as the culture soil 2 as covering soil 8 in a state of a thin layer. This is subjected to seedling growing management to obtain the objective mat-shaped seedling.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mat-like seedling having a mat-shaped floor.

[0002]

2. Description of the Related Art It is well known that mat-like seedlings are prepared by using a fertilizer mixed with soil in the mat-like floor.

[0003]

However, the fertilizer mixed in the soil as in the prior art is applied so as to be effective mainly during the seedling raising period. Therefore, in order to apply the fertilizer to the crop after transplanting to the field, it was necessary to separately apply fertilizer after transplanting. However, recently, N, P,
Fertilizers containing K as a main component have been introduced, which can be coated with a water-soluble coating agent and the thickness of the coating agent can be changed to adjust the period during which the coating agent melts and the fertilizer is effective. If this fertilizer is mixed in the bed soil at the sowing stage, it is possible to omit the fertilization work after transplantation to some extent. However, since this coated fertilizer is larger than the particle size of the bed soil, if it is simply mixed in the bed soil, a large amount of the fertilizer will spill from the bed soil when handling seedlings for transplanting, etc. There was a problem in terms of good application.

[0004]

In order to solve the above problems, the present invention provides a mat-like seedling having a layer of fertilizer coated with a water-soluble clothing material on a mat-like floor.

[0005]

The mat-like seedling of the present invention has a layer of fertilizer coated with a water-soluble clothing material at the time of sowing to form a nursery bed. It becomes a mat-shaped seedling in a state of being hugged. When transplanting this seedling, the mat-like floor part is divided into individual plants and transplanted. At this time, much fertilizer does not spill. The transplanted seedlings grow and thrive in the paddy field, and the fertilizer coating material held on the floor gradually dissolves. Then, at the properly set cultivation time, most of the clothing material is dissolved and the fertilizer is dissolved.

Therefore, fertilization work after transplanting can be performed at the time of sowing work, and the work efficiency can be improved, and the fertilizer applied at the time of sowing work is less likely to spill when handling seedlings at the time of transplanting work, thus reducing waste. . Also,
Since the fertilizer is applied in layers during sowing work, it is filled with soil, sowing,
A fertilization process can be easily added between or during each sowing work process such as covering soil, and continuous workability of the sowing work is not hindered.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As an embodiment of the present invention, a mat seedling of rice will be described in detail with reference to the drawings. First, the seedbed is formed as follows. That is, in the nursery box 1,
Fertilizer necessary for raising seedlings is prepared and mixed, and the soil is packed in layers as bottom soil 2, and fertilizer 3 containing N, P, K as the main component is added on top of it.
Is coated with a water-soluble coating agent 4 in a layered manner, and the same soil as the bed soil 2 is further layered as a medium soil 6 and seed rice 7 is sown on it. Finally, the same soil as the ground soil 2 is thinly layered thereon as the covering soil 8. When seeds are sown and managed in this way, the roots that extend from the seed pad and extend downwards extend from the middle soil layer through the coat fertilizer layer to the bottom soil layer, and are further entangled with the roots of the adjacent seedlings to form a floor. The part is formed into a mat shape. The coat fertilizer layer may be formed between the bottom soil layer and the cover soil layer, and may be formed below or above the seed paddy layer.

When the mat-like seedlings raised as described above are transplanted to the paddy field, the mat-like floor is divided into individual plants for transplantation. The transplanted seedlings are for one strain. Even in the state of being divided into pieces, the root that extends up to the bottom soil 2 and is intertwined firmly holds the coat fertilizer 5 sandwiched vertically between the soil 6 and the bottom soil 2, so the coat Fertilizer 5
Will not spill a lot. Also, when picking up the mat-like seedlings from the nursery box 1 with a seedling take-up plate or the like, much of the coat fertilizer 5 does not spill out. As described above, the transplanted seedlings divided from the mat-like seedlings one by one grow and grow on the paddy field, and at the same time, the clothing 4 of the coat fertilizer 5 retained on the floor is It gradually melts. Then, during the period from pollination to harvesting (for example, 100 days after transplantation, 100 days after the transplantation), most of the clothing material 4 is dissolved and the fertilizer 3 is dissolved.

In the formation of the above nursery, the following seeders can be used. That is, this seeder
As shown in FIG. 4, on the seeding table 10 provided with a conveyor for conveying the nursery boxes 1, ... , Seeding device 14, irrigation device 15, covering soil supply device 1
When the empty seedling raising boxes 1 ... Are transported from the transport start end of the seeding table 10 in a configuration in which 6 are sequentially arranged, the soil, the coat fertilizer, and the seed pad are sequentially supplied in layers by each device. It has become.

As described above, this mat-like seedling is applied with a layer of fertilizer coated with a water-soluble clothing material at the time of sowing to form a nursery bed. It becomes a mat-shaped seedling in a crowded state. When transplanting this seedling, the mat-like floor part is divided into individual plants and transplanted. At this time, much fertilizer does not spill. The transplanted seedlings grow and thrive in the paddy field, and the fertilizer coating material held on the floor gradually dissolves. Then, at the properly set cultivation time, most of the clothing material is dissolved and the fertilizer is dissolved.

Therefore, the fertilization work performed after transplantation can be performed at the time of sowing work and the work efficiency can be improved, and the fertilizer applied at the time of sowing work is less likely to spill when handling seedlings at the time of transplanting work, so that waste is reduced. . Also,
Since the fertilizer is applied in layers during sowing work, it is filled with soil, sowing,
A fertilization process can be easily added between or during each sowing work process such as covering soil, and continuous workability of the sowing work is not hindered.
