Abstract

PURPOSE:To provide a nursery bed material consisting of a specific constitution, capable of taking out from plug without deforming nursery bed material and transplanting without damaging seedlings even if these seedlings are young in which root pots are not formed and facilitating packing operation to the plug. CONSTITUTION:A nursery bed material 3 is formed of an organic material having strong shape holding property (preferably peat-moss) so as not to deform when taken out from a plug, and e.g. many nursery bed materials are carried on the upper face of a plug tray and these nursery bed materials are dropped into the plug by oscillating the plug tray to readily pack the materials into plug. Further, recessed parts 3a and 3a are formed in both of the upper face and the bottom of the tubular nursery bed material. Thereby, when the nursery bed material is housed in the plug, the nursery bed materials are kept so that recessed part for sowing seeds are always located on the upper side and space for stopping stretching of root is formed on a hole of the plug bottom in the recessed part located in the lower part to prevent root from protruding from the hole of the plug.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nursery bed material to be housed in each plug of the plug tray when growing seedlings such as vegetables and flowers for each strain using the plug tray.

2. Description of the Related Art Japanese Utility Model Laid-Open No. 3-27944, JP-A-3
In Japanese Patent No. 76511, there was a seedling planting material, that is, a nursery bed material, in which a soil improving material was wound in a tubular shape in a cellulose-based packaging material. In addition, this seedling raising floor material is fitted into a seedling raising hole formed in a concave shape in a seedling raising box, and then seeded to irrigate and raise seedlings. Then, when it grows to a predetermined size, the upper part of the nursery bed material is pinched out and transplanted.

[0003]

Recently, many methods have been adopted to grow seedlings of vegetables and flowers for each strain using a plug tray. Each plug of the plug tray is packed with a floor material mixed with peat moss, vermiculite, etc., and seeds are sown there, but the roots are sufficiently elongated to form a root pot to some extent. If it is not, the flooring will fall apart and the seedlings cannot be removed from the plug without damaging the seedlings, making transplanting difficult. On the other hand, if the roots grow too much and wrap around the outer surface of the flooring material and the root pot formation proceeds too much, the roots will not come out easily even if transplanted, and the rooting may be delayed or not rooted. Therefore, seedling raising using a plug tray requires a lot of seedling work because the seedlings are transplanted after the seedlings have grown to a certain size, and the transplantable period of seedlings is short, which leads to centralized transplanting work and management. Impede scale expansion.

Therefore, in the above conventional nursery floor material, since the outer periphery of the soil is wound in a tubular shape with a packaging material of cellulose base, the seedlings are just emerging and the roots are not fully grown. Even at times, it is possible to easily take out the seedlings from the seedling holes without breaking them, so that the seedlings can be transplanted without being damaged. However, this nursery floor material has to be fitted one by one in order to be fitted into the seedling-growing hole formed in a concave shape in the nursery box, so that workability at the time of sowing is poor. In addition, since the nursery floor material has the soil packed with the packaging material, the roots of the transplanted seedlings tend to extend to the soil in the field (especially, the upper roots of the seedlings (wheat roots) affect survival. However, there is also a drawback that the wrapping roots extend in the plane direction) and the wrapping material delays the survival.

Incidentally, seedling raising floor materials obtained by hardening the floor materials with various binders without wrapping them with the packaging material as in the above-mentioned conventional example are known (Japanese Utility Model Publication No. 3-335826 and Japanese Utility Model Publication No. 6-3847).
No. 6, etc.). This has a problem that the floor material has good shape retention but does not have sufficient voids in the floor material for raising seedlings of vegetables and flowering plants having weak rooting ability. Therefore, even in a seedling in a state where a root pot is not formed, it can be taken out from the plug without breaking the seedling bed material so that it can be transplanted without damaging the seedling, and a seedling bed material that enables it. The challenge is to develop a nursery bed material that can be easily planted when it is packed in a plug and that enables efficient sowing work.

[0006]

In order to solve the above-mentioned problems, the present invention is characterized in that an organic material having a strong shape-retaining property is formed into a columnar shape, and recesses are formed on both upper and bottom surfaces thereof. And used as a nursery floor material.

[0007]

Therefore, when seedlings are raised in a plug tray using this nursery bed material, even if the seedlings have no root pot, they can be taken out from the plug without breaking the nursery bed material. It can be transplanted without damaging it and can be successfully rooted in the field. In addition, this seedling bed material can be easily packed into a plug, which enables efficient seeding work.

An embodiment of the present invention will be described in detail below with reference to the drawings. First, the plas tray 1 used for raising seedlings will be described. The plug tray 1 has a plurality of plugs 2 on the left, right, front and back.
Are arranged, the openings 2a ... of the respective plugs 2 are connected to each other, and the bottoms 2b ... The outer peripheral edge of the plug tray 1 is rectangular in plan view, and the size is 300 mm × 600 mm in length and width, and is a size that can be accommodated in a general seedling raising box for paddy rice seedling raising. Each plug 2 of the plug tray 1 has an opening 2a.
, And the bottom portions 2b are circular in plan view and trapezoidal in side view in which the lower side is shorter than the upper side. These plugs 2 are 16 in the horizontal direction and 8 in the vertical direction on the plug tray 1 for a total of 12
Eight are formed. Round holes 2c are provided in the bottom portions 2b. The holes 2c ... Are not limited to the hole shape and may be in the form of cracks. (FIGS. 1 and 2) In order to raise seedlings using the plug tray 1 configured as described above, first, the seedling raising flooring materials 3 are packed in the respective plugs 2. Next, seeds 4 such as vegetables and flowers are sown in the recesses 3a formed in the nursery bed material 3. Then, the soil is covered with the soil 5. After sowing as described above, under appropriate temperature control, irrigation is performed as needed at appropriate times to raise seedlings. The plug seedling N thus raised is taken out from each plug 2 in the plug tray 1 and transplanted (FIG. 4).

By the way, the seedling nursery materials 3 to be packed in the respective plugs 2 of the plug tray 1 are formed of an organic material having a strong shape-retaining property. Peat moss is specifically preferable as the organic substance having a strong shape-retaining property. Peat moss is rich in moldability, has strong shape retention after molding, has sufficient voids, and has high water retention. It should be noted that any material that can be molded into the above-mentioned shape and has a strong shape retention property may be used. Further, it is preferable that the nursery bed material 3 is made to contain zeolite, bentonite or the like having a high fertilizing property, and a fertilizer such as nitrogen, phosphoric acid or potassium is added. Therefore, this nursery bed material 3 ...
When the plug seedlings N ... are raised by accommodating them in the respective plugs 2 ... of the plug tray 1, even vegetables and flower seedlings having weak rooting ability can be satisfactorily grown. When transplanting, nursery bed material 3 ...
Does not adhere to the inner surface of the plug 2 ... like soil, and the seedling flooring material 3 maintains its shape without breaking, so it is easy to remove the seedling from the plug 2 ... without damaging the seedling. .
Therefore, even at the time of seedlings in which the root pot is not formed, transplanting can be done without damaging the seedlings, labor saving of seedling raising work can be achieved, and the transplantable period of seedlings can be extended. It is possible to improve the workability by eliminating the concentration of porting work. Further, after transplanting, since there is no factor in the nursery bed material 3 that hinders the roots in the nursery bed material 3 from extending in the plane direction, the roots of the transplanted seedling N are smoothly transferred to the soil in the field. Extend and live.

When removing seedlings from the plugs 2, ...
It is possible to pull out the seedlings by sticking an extrusion stick through the holes 2c on the bottom of the plug to push out the nursery flooring material 3 ... it can. Also, as shown in FIGS.
The nursery floor material 3 is formed into a columnar shape and is sized so that it can be accommodated in the plugs 2 of the plug tray 1 with a slight gap. The columnar shape of the nursery floor material 3 is not limited to the circular shape of all the cross sections having the same radius, and is a shape that follows the inner shape of the plug 2 if the cross section has a circular shape. May be. When the seedbeds 3 are packed in the plugs 2, the plug tray 1 is fitted in the frame 6 to surround the periphery thereof, and a large number of seedbeds 3 are packed in the plug tray 1 as shown in FIG. On top of. When the plug tray 1 is shaken by holding the frame 6 to the left, right, front, back, etc., the seedling raising floor materials 3 fall into the plugs 3 and are fitted. In this case, the size of the nursery bed material 3 is such that the height h of the nursery bed material 3 and the diameter d of the nursery bed material 3 are h / 2 ≦ with respect to the diameter d ′ of the opening 2a of the plug 3. When d '/ 2 d <d', the nursery floor material 3 is easily vibrated to plug 3
… Easy to drop inside.

Further, the nursery floor material 3 is formed by forming concave portions 3a, 3a on both surfaces of a cylindrical upper surface and a bottom surface and in the center of these surfaces. Nursery bed material 3 as described above
When vibration is dropped into the plug 3 and packed, the nursery floor material 3 is packed with the columnar upper surface facing up and the bottom surface facing up, but the concave portions 3a are formed on both the upper surface and the bottom surface.
Since the 3a is formed, the nursery bed material 3 accommodated in the plugs 2 will always have the concave portions 3a on the upper side. Therefore, at the time of sowing, if the seeds 4 are sowed in the recesses 3a arranged on the upper side thereof, the growing portion of the seedling with respect to the nursery floor material 3 can be set at a predetermined position, so that the adjacent plugs 2 ... The intervals with the plug seedlings N grown in step 1 are even and uniform seedlings can be grown. On the other hand, the concave portion 3a arranged on the lower side forms a space S above the hole 2c of the plug bottom portion 2b. If this space S is not present, the seedlings may grow and the roots may come out of the holes 2c and extend downward. In this case, the seedlings may be difficult to pull out from the plug, and the roots may be torn off when the plug is pulled out, resulting in damage. There is a problem that ends up. However, when the space S is formed by the recessed portion 3a arranged on the lower side, the root extending to the space S stops growing there, and the root cannot come out of the hole 2c. This makes it easy to pull out the seedlings from the plugs 2 ... Without damaging the roots. The recess 3a
The shape of 3a ... is not limited to the shape shown.

Therefore, when the nursery floor materials 3 ... Are packed in the plugs 2 ...
Moreover, uniform seedlings can be grown. As described above, this nursery bed material is a nursery bed material characterized by forming a strong shape-retaining organic material into a columnar shape and forming recesses on both upper and bottom surfaces thereof. Therefore, if this seedling bed material is used to grow seedlings in a plug tray, even seedlings in a state where no root pot is formed can be taken out without breaking the seedling bed material and transplanted without damaging the seedlings. Can be made to live smoothly. In addition, this seedling bed material can be easily packed into a plug, which enables efficient seeding work.
