Description

  The present invention relates to a seedling mat for efficiently performing germination and seedling of plants such as turf and a seedling and planting method using the same, more specifically, not only can the germination and seedling efficiently be performed, The present invention relates to a seedling mat that can be formed into a form that can be easily conveyed and planted for distribution, and a seedling / planting method using the same.

Conventionally, when growing plants such as turf, turf seeds are evenly pasted on a sheet of paper and spread on the planting surface, and then held by a suitable holding means such as a net. The method of spontaneous germination is taken.
The above method is effective in reducing the labor of sowing at the planting site, but since germination and seedling are carried out in the natural environment, the germination and seedling are greatly affected by the weather, and in particular, weeds In a place where the overgrowth is intense, the grass often loses its weeds and hinders its growth.

  On the other hand, in fields that produce turf for sale, a company familiar with turf cultivation germinates and cultivates the seeds seeded there, and when it grows moderately, the topsoil where the turf is rooted is divided into the sales unit area. They are cut out and bundled appropriately for shipment. In this case, turf cultivation management is performed appropriately, but because the sales form is with topsoil containing moisture, the weight is heavy and the surroundings are soiled, and the cultivation in the field is only in the natural environment For this reason, the cultivation cycle is limited to twice a year. Moreover, since the above-mentioned topsoil is attached, it is difficult to avoid weed contamination, and pathogens and pests may be mixed.

The present invention has been made to solve the above problems, and its technical problem is to enable efficient germination and raising of plants such as turf and to shorten the growing period thereof. An object of the present invention is to provide a nursery mat and a seedling method using the same.
Another technical problem of the present invention is that a seedling growth mat obtained by seed growth can be formed into a form that can be easily conveyed and planted for distribution, and a seedling / planting using the same It is to provide a method.

Another technical problem of the present invention is to provide a seedling mat that is less likely to be mixed with weeds and pathogens and pests, and a seedling raising method using the same.
Still another technical problem of the present invention is to provide a seedling mat that has good growth after planting and can suppress the growth of weeds, and a seedling / planting method using the same.

  The seedling mat of the present invention for solving the above-mentioned problems is basically obtained by sticking seeds to be seeded and a water-retaining granular lightweight aggregate with a water-soluble paste on the surface of the mat body formed of a nonwoven fabric. It is characterized by that.

In a preferred embodiment of the seedling mat of the present invention, liquid fertilizer is held between the single-layered or plural-layered nonwoven fabrics in the mat body, or between the nonwoven fabrics formed by laminating two or more layers of nonwoven fabrics. Vermiculite is used as the fertilizer and as the water-retaining granular lightweight aggregate.
The liquid fertilizer may be applied simultaneously with irrigation of the seedling mat or separately from irrigation when the seedling mat is laid in a plant-growing house for raising seedlings.
As the seed, turf or a similar plant, specifically, a plant seed grown so as to have a two-dimensional spread is suitable.

On the other hand, the seedling raising method of the present invention for raising seedlings using the seedling mat is characterized by laying in a plant growing house, irrigating the seedling mat and germinating and raising seeds of the seedling mat. is there.
Moreover, the seedling mat obtained by the seedling raising method is cut into a required shape as necessary, wound in a roll shape and conveyed to a planting area, and the seedling mat is laid and fixed in the planting area. This method is effective as a seedling / planting method using the seedling mat.

According to the seedling mat of the present invention described in detail above, germination and seedling of plants such as turf can be carried out in a house for plant growth, so that it is possible to efficiently raise seedlings and the growing period thereof. Since the seedling growth mat obtained by seed growth can be formed in a form that can be easily transported and planted for distribution, handling after seedling is extremely easy.
In addition, according to the present invention, it is possible to obtain a seedling mat that is less likely to be mixed with weeds, pathogens and pests, and has a good growth after planting and can suppress the growth of weeds. Obtainable.

Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings.
As shown in FIG. 1, a mat body 2 of a seedling mat 1 according to the present invention is formed by laminating two nonwoven fabrics 11, 11, and seeds 21 to be seeded and water-retaining properties are formed on the surface of the mat body 2. The granular lightweight aggregate 13 is pasted with a water-soluble paste. When the seeds 21 and the granular lightweight aggregate 13 are attached, a water-soluble glue material is sprayed on the surface of the mat body 2 to form a glue layer 15, and the seeds 21 are entirely covered on the glue layer 15. While spreading so that it is evenly distributed, the water-retaining granular lightweight aggregate 13 is sown from above, and the glue layer 15 adheres the seed 21 and the granular lightweight aggregate 13 together.

Here, the mat body 2 is formed by laminating two nonwoven fabrics 11 and 11 and holding the fertilizer 23 between the laminated nonwoven fabrics 11 and 11. However, the mat body 2 is not limited to two nonwoven fabrics, and has a plurality of layers. The non-woven fabric 11 can be formed by laminating, and in that case, the fertilizer 23 can be interposed on the arbitrary laminated surface of the non-woven fabric. Thereby, the fertilizer part melt | dissolved by daily irrigation can be absorbed by the root which protruded from the germinated seed.
Further, liquid fertilizer can be held between the single-layered or multiple-layered nonwoven fabrics 11 in the mat body 2. The liquid fertilizer may be applied simultaneously with irrigation of the seedling mat or separately from irrigation when the seedling mat is laid in a plant-growing house for raising seedlings.

The non-woven fabric 11 may be a commercially available product formed by bonding an intersection of chemical fibers or natural fibers, or a mixed fiber thereof with an adhesive, and has both drainage and water retention. In addition, it can retain moisture absorbed by the roots and not only suppress root decay due to its drainage but also supply necessary oxygen around the roots due to its high porosity, thus maintaining root activity. Be drunk.
The nonwoven fabric 11 is preferably one that retains its form as a seedling mat 1 in the order of at least several years, and then decomposes and returns to the soil over time.

As the water-retaining granular lightweight aggregate 13, porous, light and water-retaining vermiculite is most suitable, which creates an appropriate water-retaining and heat-retaining environment when germinating the seeds 21, thereby achieving good germination. Effective to promote. The granular lightweight aggregate 13 is not limited to vermiculite, and other similar materials such as zeolite can also be used.
As the paste material for fixing the seed 21 and the granular lightweight aggregate 13 on the mat body 2, it is desirable to use starch paste or a material that is harmless to animals and plants such as polyvinyl alcohol. The solution is adjusted to an aqueous solution having a concentration that can be easily attached and temporarily stopped until the seeds 21 germinate, and sprayed onto the mat body 2.
Further, as the seed 21, turf or a similar plant, specifically, a seed of a plant grown so as to have a two-dimensional spread, such as sedums, is suitable.

Next, a method for germinating and growing turf using the seedling mat 1 will be described.
When raising seedlings using the seedling mat 1, first, a stand for laying the seedling mat 1 is installed in the plant growth house. The seedling mat 1 is irrigated periodically.
The seedling mat 1 is not limited to the shipping unit area, and can be cut into a size suitable for the area of the planting area at the time of shipment, for example, by multiplying it by an integer multiple thereof.

When the above irrigation is performed, the seeds 21 are moistened and also retained in the water-retaining granular lightweight aggregate 13, the excess water reaches the mat body 2 and is partially retained between the fibers of the nonwoven fabric 11, Part of the fertilizer 23 intervening on the laminated surface is dissolved, and the liquefied fertilizer is held between the fibers of the nonwoven fabric 11, and excess water passes through the mat body 2 and is discharged to the outside.
And the seed 21 of the said seedling mat 1 is germinated by this irrigation and the growth management in a house, and it can be set as the seedling growth mat 1A as shown in FIG.

  In particular, in the house, since the environment suitable for germination and seedling raising can be controlled, the seed 21 germinates and roots early due to moisture given from the water-retaining granular lightweight aggregate 13, and the root 24 is matte. The seedling 25 grows while projecting into the main body 2, and further grows by absorbing fertilizer that gradually melts by irrigation on the laminated surface, and grows more efficiently in a shorter period of time compared to the case of raising the seedling in the field. Can be made. Further, the germinated seedlings 25 are given appropriate moisture by the granular lightweight aggregate 13 having water retention on the surface of the mat body 2, and the roots enter between the fibers of the nonwoven fabric 11 having a high porosity, It will grow in a good environment given by drainage and water retention.

  The grass cultivated in this way in the house does not use soil, so it hardly receives disease due to bacteria in the soil or pest damage. In addition, since the temperature and irrigation can be freely controlled, grasses with the same degree of growth can be cultivated in a short period of time, and efficient shipment can be performed systematically. Therefore, the shipping cycle is shorter than that in cultivation in a natural environment field, and the annual shipping amount can be increased.

The seedling growth mat 1A obtained as described above is formed in a roll shape as shown in FIG. 3 as it is, if it is formed in the shipping unit area, or after being cut into a required shape if necessary. It can be further grown by winding and transporting it to a planting area, and laying and fixing the seedling growth mat 1A as it is in the planting area. In this case, it can be rooted in the soil from the lower surface of the seedling growing mat 1 </ b> A and can be easily established by the presence of the nonwoven fabric 11 and the lightweight aggregate 13.
Moreover, when planting using the said seedling growth mat | matte 1A, since the surface of the soil of a planting area is covered with the said nonwoven fabric 11, germination of a weed can be suppressed and management after planting can also be performed very easily. it can.

  The seedling breeding mat 1A grown on this seedling mat 1 does not use soil, so it is lightweight when transported, and what is wound in a roll shape as described above can be shipped in, for example, cardboard, etc. Compared to the case of cutting the entire topsoil where the turf is rooted into the sales unit area and bundling and shipping them as appropriate, there is no need to worry about dirt.

  The present invention is not limited to the above-described embodiments, and various configurations can be made without departing from the scope of the claims.

It is sectional drawing which shows the state before seed germination of the seedling mat based on this invention. It is sectional drawing which shows the seedling raising state in the said seedling raising mat. It is a perspective view for demonstrating an example of the shipment form of a seedling breeding mat.
