Description

Seedling mat {SEEDLING MAT}

The present invention is to enable / provide an improved seed / seed mat, particularly a rice seed mat, that is intended to optimize mat availability. The present invention is not only to provide materials with specific properties and the use of such materials in the seed mat, but also to provide a component layer that can be made of such materials and incorporated into the seed mat. One such component serves as a seed cover component in the assembled seed mat and improves the seeding germination and growth of the seedlings while potentially providing moisture and nutrients, Temperature, birds and insects). ≪ / RTI > The present design also utilizes hot melt adhesives in preparation of seeds / seedlings mat as well as preparation of components for such seedlings mat. Moreover, the present invention also relates to a method for producing such seed / seedlings mat and / or component layers, and in particular to the production of rooting substrate components and / or seed cover components for use in such seedlings mat .

In farming (and general horticulture), the seedling is initially grown in a special environment such as a nursery, a glasshouse or a dedicated seed-bed area. In this way, certain environmental factors can be more easily controlled to improve the likelihood and quality of its initial occurrence. Subsequently, the seedlings are transplanted into a field / garden for long-term growth.

Seed mats facilitate early settlement and propagation of seedlings, convenient seed / seed transport for storage and also seedling / greenhouse, and subsequent long-term cultivation and growth (e.g., in rice fields).

Mat type products including seeds are known in the market. Patent document WO 01/60144 A1 discusses the problems associated with raising seedlings and discloses an embodiment which is intended to provide only lightweight alternatives to seed bed soil and which requires vacuum forming in its manufacture.

In order to improve its usefulness, seed / seed mat (hereinafter referred to as seed mat) must solve various aspects related to seed / seedling handling and propagation. For example, it is desirable to simultaneously balance seed protection and environment, mat integrity (e.g., for ease of handling and portability), and growth promotion / control within the mat and after implantation.

A wide variety of mats exist in the prior art, including seeds and different component layers. Many mats use aqueous glue throughout their manufacture. The use of such adhesives can result in a high moisture content in the seed mat during production, which may include (i) the time it takes to dry the mat, and / or the need for specific equipment to dry the mat, (ii) The space required to store such a mat, and / or (iii) the high humidity present in the mat, due to unwanted premature seed germination.

The present invention solves these problems through two ways: (i) through the use of hot melt adhesives; and (ii) by the production of a seed cover component in a compressed and pre-dried form, To minimize the unwanted initiation of germination of the seeds caused by the high water content in the assembled prior art mat and to provide an unexpected beneficial effect on the growth of seeds / seedlings grown in the mat comprising such seed cover components It affects. This resulted in an improved seed mat that was intended to optimize mat availability. The present design also provides for the use of materials with specific materials and specific properties in the seed mat and a product (component) layer that can be incorporated into the seed mat.

Thus, in a first aspect, the present invention provides a seed mat,

A substantially planar rooting material that is seed-root-supported and self-supporting, wherein one surface is coated with a seed adhesive to fix the seeds in or on the top surface area of the rooting material;

A seed cover component that covers seeds and allows for seedling growth through it; And

A plurality of seeds distributed in or on the top surface area of the root material and attached to the root material by a seed adhesive;

The seed cover component is self-contained and comprises an organic material compressed into a self-supporting layer, wherein the organic material is selected from the group consisting of coir, rice husk, guar gum, and bagasse ≪ / RTI >

In another aspect, the present invention provides a seed cover component for a seed mat, wherein the component comprises an organic material that is self-contained and compressed into a self-supporting layer, wherein the organic material is selected from the group consisting of coir, chaff, ≪ / RTI >

In another aspect, the invention provides a rooting rest component for a seed mat, the component comprising a generally planar layer of a stone wool coated with a hot melt adhesive on one surface, Generally have a vertical perforation.

It will be appreciated by those skilled in the art that the above-described subject matter pertains to seed mat and components, and therefore those skilled in the art understand that the term " rooting material " will be.

As used herein with respect to any component, the term "self-supporting" means that the formed component has structural integrity, can be treated as a separate product without collapsing, and does not require additional support elements . This differs from the loose layer of the coating or soil which can not be treated as a separate layer without, for example, some other support elements. Thus, the roots reconstitution component and / or the seed cover component of the present invention are sufficiently robust to grip by hand.

As described above, the rootstocks are self-supporting, allowing germination followed by support of seed root growth in the rooting material. This root material should preferably allow the generation of strong, healthy and white roots and be able to be subsequently fixed following implantation. Also, the root material should support the structural integrity of the assembled mat by, for example, being continuous instead of broken.

Preferably, the root material comprises a mineral wool (also known as stone wool). Specific examples include Rockwool ^® (supplied by Grodan) and Stone Wool from Cultilene. In this way, the mat flexibility facilitates roping up and loading into a commercial implanted machine. The mineral wool / stone wool may be in the form of a vertically-spun, horizontal-spun or multi-direction spun (i.e., the fibers do not have a preferred orientation as in X- ).

The root material can be unperforated or perforated (e.g., to facilitate root growth into the root material). The perforations can be substantially vertical and extend partially or completely through the root canal. The partial perforations can extend, for example, into the rooting material by about 0.1 to 1 cm, more preferably about 0.5 to 1 cm. The perforations can be approximately 0.1 to 1 mm in diameter and are preferably present at a density of about 1 to 4 (inclusive) perforations / cm 2 of the root material. Preferably, the root material comprises perforated stone wool of the vertical spun type. Preferably, the perforations extend about 0.5 cm into the rooting material.

Alternatively, the root material is about 0.5 to 2.6 cm in thickness, e.g., about 0.5 cm, 1 cm, 1.5 cm, 2 cm, or 2.6 cm in thickness. Preferably, the root material has a thickness of about 1 to 2.6 cm, more preferably a thickness of about 1.5 cm to about 2 cm, and conveniently a thickness of about 1.5 cm or about 2 cm.

The root reconstruction component (and thus any subsequently assembled seed mat) may be of any size suitable for growing the seeds in the seedling and then transplanting into the field, but is preferably rectangular. Conveniently, the width of the rooting reconstitution element / seedlings mat is from 20 to 50 cm, preferably from about 25 to 40 cm, more preferably from about 25 to 30 cm (inclusive) The length of the seed mat is in the range of 50 to 100 cm, preferably about 50 to 75 cm, and more preferably about 55 to 60 cm (including the boundary value). In this way, the use of a mechanical implant machine can be facilitated to implant the seed mat. The rooting reconstitution element / seedlings mat may also be made to have a longer length (e.g., a length of about the same length, e.g., 2x, 3x, 4x, 5x times, etc.) Can be used initially in this form for storage, transport and / or initial growth of the seedling in the embryo environment, before being cut to shorter lengths. Preferably, the width of the rooting rest component / seed mat is about 25-30 cm, and the length of the root reproductive element / seed mat is about 55-60 cm. In certain embodiments, the surface area of the rooting reconstitution element / seedlings mat is about 28 cm x 58 cm.

As described herein, the root material is preferably coated with a seed adhesive, which is a hot melt adhesive, on one surface (corresponding to the upper surface of the root material in use on the assembled seed mat of the present invention). In one embodiment, the roots reconstitution element of the present invention further comprises a separation layer disposed on top of the hot melt adhesive layer. In another embodiment, the seed may be applied to the root remanufacturing element prior to the addition of the separation layer, and the separation layer is disposed on top of the seed and adhesive layer in this embodiment. By securing the seeds, the seed glue increases the practicality of carrying the mats (or sowed root component).

The use of a hot melt adhesive reduces the overall moisture content in the seed mat, thereby facilitating its production (as it reduces the time and space required to dry the seed mat) and (e. G. By minimizing unwanted premature germination of the seeds caused by the higher humidity present in the mat produced using the aqueous adhesive).

The use of such an adhesive to coat the surface of the rooting material and to attach the seeds to the assembled seedling mat also facilitates the preparation of such a mat in the form of a component. Thus, it allows the rooting reconstitution component to be manufactured in a place different from the rest of the seed mat, for example, to be assembled with the remaining components in the seedling.

Hot melt adhesive means a thermoplastic adhesive which is applied in a molten form at a temperature exceeding 100 DEG C and solidifies upon cooling. Preferably, the operating temperature of the hot melt adhesive is 150 deg. C or higher and 200 deg. C or lower, preferably 155 deg. C or higher and 190 deg. C or lower, more preferably 160 deg. C or higher and 185 deg. C or lower, and most preferably 160 deg. Lt; / RTI > Examples of hot melt adhesives suitable for use in the present invention include ethylene-vinyl acetate adhesives, ethylene-acrylate adhesives, polyolefin adhesives, polyamide and polyester adhesives, polyurethane adhesives, styrene block copolymer adhesives Also known as styrene copolymer adhesives and rubber adhesives). Hot melt adhesives, which are pressure-sensitive adhesives, are particularly useful in the present design because they facilitate the production of component parts of a seedless seed mat. For example, one surface may be coated with such an adhesive that does not bond until the pressure is applied while maintaining the degree of tackiness even when the rooting material is solidified. This is particularly advantageous since the seed can then be applied when the adhesive is at a temperature that minimizes or even avoids potential thermal damage to the seed, e.g., at room temperature. The degree of tackiness is sufficient to maintain the seed in place during transport in embodiments in which the seed is sown on top of the root remanufacturing element.

Therefore, the styrene copolymer and the rubber-based hot melt adhesive are particularly preferable because they provide such a pressure-sensitive property. Examples include H1125 having a softening point of about 75 ° C to 90 ° C, an operating temperature of 160 ° C to 175 ° C, and a typical viscosity of 14 to 20 poise at 160 ° C and 9 to 14 poise at 175 ° C / 6 ™, a blend of thermoplastic rubbers such as H1155 ™ (Sealock), resins and plasticizers; A styrenic block copolymer such as D74 (TM) (Powerbond Adhesives Ltd) having a softening point of about 88 占 폚 to 98 占 폚, an operating temperature of 160 占 폚 to 170 占 폚, and a viscosity at 170 占 폚 of 6500 占 1700 cPs Blends. Thus, in one embodiment, the hot melt adhesive used has a softening point of about 75 DEG C to 90 DEG C, an operating temperature of 160 DEG C to 175 DEG C, and a viscosity of 14 to 20 poise at 160 DEG C and 175 DEG C Resins and plasticizers having a typical viscosity of from 9 to 14 poise at a temperature of from about < RTI ID = 0.0 > 90 C < / RTI & And a blend of styrenic block copolymers and synthetic resins having a viscosity of from 48 to 82 poise at 170 < 0 > C.

The use of hot melt adhesives, and in particular of a pressure-sensitive hot melt adhesive, can also be achieved by using, for example, an optionally perforated stone wool coated with one surface with the hot melt adhesive as described in the Examples herein Facilitates the production of rooting reconstitution components in the form of components.

As described above, when made in the form of a component, the adhesive coated rootstock may further comprise a separate layer to facilitate packing, storage and / or transport. Such a separation layer is removed prior to use / assembly into the whole seedling mat. Suitable separation layers include silicone paper, waxed paper, rice paper, potato starch paper and PVOH film.

To produce the root remanufacturing element of the present invention, the mineral wool root material is cut to the desired size and selectively apertured using any suitable method, especially using a perforator as described herein. The hot melt adhesive can be applied using any suitable application means, for example, on a small scale, where hot melt glue guns and suitable nozzles can be used, or in ITW Dynatec DDS Delta Fx (TM) Fibrous Spray Applicators or similar (e.g., AltaSpray A Nordson AltaBlue (TM) TT series melter with a stirrer and signature nozzle). Thereafter, a suitable separating layer (e. G., Silicon paper, wax paper, or those described above) may be placed on top of the adhesive coated rooting material. The separating layer serves to prevent the rooting reconstitution component from attaching to each other material / packaging material when stored and / or transported. Thereafter, rooting restructuring elements may be packaged for storage and / or transport, or alternatively may be used immediately. Alternatively, it can be arranged in a rooting barrier as will be described below is rooting material components, such rooting barrier may form an additional part of the packaging. In embodiments in which the pre-seeded root remediation component is made, the seeds may be applied to the seed mat as described below before application of the isolation layer.

In the seed mat or pre-seeded root remanufacturing element of the present invention, the seed is seeded on top of the root material and attached to the root material by a seed adhesive. Such seeds are preferably in a non-germinated state. In certain embodiments, such seeds are rice seeds. Seeds from any suitable inbred or hybrid hybrid rice variety can be used (e. G., IR64, NK3325, Koshihikari, TR-10 and ADT-34). Prior to incorporation into the mat, the seeds may be seeded, for example, with insecticides, fungicides, herbicides, nematicides, molluscicides, toxic safeners, plant growth regulators, micronutrients and / Or pretreated with fertilizer. In one embodiment, the seed is pretreated with thiamethoxam (Cruiser ^® , Syngenta). Preferably seeds of about 100 to 150 g are used for mats having a size of about 58 cm x 28 cm. Conveniently, approximately 150 grams are used for such mats for homologous breeding seeds, and about 100 grams are used for such mats for hybrid breeding seeds. Thus, the (rice) seed density is conveniently in the range of 1 to 20 seeds / cm2 (inclusive), preferably 1 to 15 seeds / cm2 (inclusive) and more preferably 1 to 10 seeds / Including the boundary value). Those skilled in the art will appreciate that the seed density will vary depending on the thousand grain weight for any given variety. For example, for the IR64 breed rice seeds, the preferred seed density is in the range of 1 to 5 seeds / cm2 (inclusive) and the preferred seed density for the NK3325 rice seeds is 1 to 7 seeds / Including the boundary value).

As previously described, in the assembled seed mat of the present invention, the seed cover component is used to improve the seedling germination and growth, consistent with environmental factors (e. G., Ambient radiation, Temperature, birds and insects). ≪ / RTI > The production of the seed cover component in a compressed and pre-dried form facilitates mat assembly and minimizes the unwanted initiation of seed germination caused by the high moisture content in the assembled prior art mat, Has an unexpected and beneficial effect on the growth of seeds / seedlings grown within the mat containing the components.

The seed cover component must be able to allow the seedlings to grow through it during use, in order to be suitable for use on the seed mat. As discussed above, the seed cover component comprises an organic material selected from the group consisting of coir, rice hull, guar gum, and bagasse. Moreover, these seed cover elements are distinguished from the materials used in the prior art in that they preferably do not include soil, wood pulp, straw and / or cotton.

The coarse may be filtered, and / or pre-washed, buffered (e.g., to pH 6.0), and dried to provide a standard particle size (e.g., 22.8 mm) prior to use. The rice husk and the bur gas may be crushed (crushed) and not crushed (crushed).

Preferably, the seed cover component comprises coarse, coir and guar gum, coarse and burger, or coir and rice hulls.

The preferred weight ratio (Coir to Burgess) is 1: 1; 3: 2; 7: 3; 4: 1 and 9: 1. 3: 2 is particularly preferable. The use of pulverized burr gas is also particularly preferred.

When the seed cover component comprises coarse and rice husk, the preferred weight ratio of coarse to rice husk is from about 10: 1 to about 1: 1, preferably from about 5: 1 to about 1: 1, About 4: 1 to about 2: 1.

Optionally, the organic material can be combined with the adhesive prior to compression. Adhesives suitable for use in the preparation of the seed cover component include, for example, aqueous system adhesives such as VAE (vinyl acetate ethylene), polyvinyl acetate (PVA), polyvinyl alcohol (PVOH) and acrylic adhesives. PVOH adhesives such as E3443C (Sealock) and VAE adhesives such as E1215C (TM) (also Sealock) are preferred, with PVOH being particularly preferred.

It is particularly preferred to include such adhesives in seed cover components, including coilers, coir and buzzgas, or coir and rice hulls. In such an embodiment, the weight ratio of organic material to adhesive is in the order of about 5: 1 to 5: 2. Conveniently, the weight ratio is from about 4: 1 to about 3: 1.

Alternatively, the organic material is selected from pesticides, biological treatment agents and / or nutrients (e.g., herbicides, insecticides, bactericides, molluscicides, nematicides, toxic emollients, plant growth regulators, micronutrients and / or fertilizers) May be combined with one or more additional agents. In particular, organic materials can be combined with fertilizers.

The organic material may optionally be mixed with the adhesive (s) and / or additional agent (s) as described herein, and thereafter applied at a pressure of from 100 to 250 kgf / cm 2, And compressed to a pressure of about 220 kgf / cm 2. If an adhesive is included, the seed cover component may be dried prior to subsequent use in storage / packaging / transport and / or seedling mats as described herein. To facilitate packing, storage and / or transport, a separating layer may be placed over the seed cover component. Suitable separating layers include, for example, silicone paper, wax paper, rice paper, potato starch paper and those made from PVOH films.

The seed cover component can be of any size suitable for future use on the seedling mat, but is preferably square or rectangular. Conveniently, the width of the seed cover component is from 20 to 50 cm, preferably from about 25 to 40 cm, more preferably from about 25 to 30 cm (inclusive) and the length of the seed cover component is 20 To about 100 cm, preferably about 20 to 75 cm, and more preferably about 25 to 60 cm (including the boundary value). The seed cover component may be manufactured to have a longer length and / or width (e.g., a length of approximately the same length, such as 2x, 3x, 4x, 5x times, etc.) Before it is cut to a smaller size in order to make it easier to store and / or transport it. Preferably, the width of the seed cover component is about 25-30 cm, and the length of the mat is about 25-30 cm or about 55-60 cm. In certain embodiments, the surface area of the seed cover component is about 27 cm x 28 cm or about 28 cm x 58 cm.

The depth of the seed cover component is less than 10 mm, preferably less than 5 mm, and more preferably less than 3 mm. In one embodiment, the depth of the seed cover component is on the order of 2 to 3 mm. Those skilled in the art will appreciate that the depths indicated apply to the seed cover component immediately after assembly into the seed mat and / or at the time of manufacture, as described below. In the assembled seed mat, such a process can cause the depth to expand beyond the above-mentioned characteristics when used, i.e., when water is applied, and / or when the seed is germinating / germinating and the seedling is growing have.

The seed cover component as described herein is then placed on top of the rooted rooting material.

If appropriate / desired, the mat may include a seed cover adhesive for attaching the seed cover component to the underlying layer as described herein. Suitable seed cover adhesives include hot melt adhesives as discussed above for seed adhesives. It can be applied on seeds. In an alternative embodiment, the physical force alone may be convenient to retain the seed cover component in other ways. In another alternative, the seed adhesive may also function as a coating adhesive.

Preferably, the seed mat of the present invention further comprises a root barrier structure in which the root material is received, wherein the barrier structure is configured to inhibit lateral and / or downward root growth beyond the periphery of the root material. The root barrier structure must support the mat structure and make the mat easier to handle. The root barrier structure may be disposed on the side of the root material and / or around the base region. In this way, the seedling root is prevented from penetrating into the soil in the seedling and / or being entangled with the root of the seedling in the adjacent mat. Preferably, the root barrier structure extends peripherally around all sides and encompasses the lower side of the rooting material.

Preferably, the root barrier structure has structural stiffness that aids in supporting and binding the rooting material, the seed cover component, and / or the top cover (described below). In this way, the handling of the mat in both the original position and during transport is facilitated, for example by preventing the seed cover component and / or the top cover from falling out.

The root barrier structure can be considered to be separate or integral to other mat components, for example, depending on the fitability and how easily the root barrier structure can be separated. For example, during / after manufacturing, the seed mat can be formed / placed, for example, in a plastic tray, which acts as a root barrier structure and facilitates handling during seeding growth. The mat can then be simply removed from the plastic tray for subsequent implantation.

The root barrier structure may be provided with a plurality of channels opposing adjacent root members. In this regard, the channel can promote root growth in a particular direction. For example, the barrier structure may be provided with a plurality of generally parallel channels extending over the upper surface of the base region. In this way, subsequent root damage when the seedlings are mechanically removed from the mat and transplanted into the field can be reduced. The channel may extend generally parallel to the shorter edge of the matte edge, for example a rectangular mat. The channel may conveniently be found integral with the barrier structure.

In one embodiment, the root barrier structure is a tray having a base region and an upright sidewall. The tray is preferably formed of plastic material or (structural) cardboard.

The cardboard provides a degree of flexibility that mats can help when used with automatic implants. Moreover, after the seed growing period, the deterioration of the cardboard can further facilitate subsequent winding and handling of the mat for implantation. Thus, the cardboard is conveniently relatively thin. The root barrier structure may also act to alleviate changes in the mat humidity during storage.

Optionally, the seed mat further comprises an upper cover overlying the seed cover component. In this manner, the seed cover component can be protected, for example, from insects, incidental moisture, and the like, while the assembled mat in general is being handled. In one embodiment, the top cover is water soluble and / or perforated. The top cover may comprise paper or (polymer) film such as rice paper, potato starch paper, polyvinyl alcohol (PVOH) film or glue film. Liquid chemical coatings may also be used.

Conveniently, the top cover PVOH film may have a thickness of 10 to 300 microns (inclusive). Preferably, the thickness will range from about 30 microns to 45 microns.

A top cover adhesive may be used between the seed cover component and the top cover.

Conveniently, the adhesive (s) used in the seed cover component and / or the top cover (when separate adhesives are used in addition to the seed adhesive) are, for example, VAE (vinyl acetate ethylene), polyvinyl acetate ), Polyvinyl alcohol (PVOH), and acrylic glue (s). In other embodiments, the seed cover component and / or the adhesive (s) used in the top cover may be a hot melt adhesive as previously described. In making the mat, the adhesive (s) may be applied by any suitable method including, for example, spraying, rolling, foam, and slurry.

Adhesives (e.g., aqueous adhesives, such as PVOH glue, or hot melt adhesives) may also be used as the top cover.

Conveniently, one or more seed mat (s) (including rooting material, root barrier structure, glue (s), seeds, seed cover component and / or top cover) may contain one or more plant protection chemicals, pesticides, Or it may be pretreated with a treating agent and / or a nutrient (e.g., a herbicide, a pesticide, a bactericide, a molluscicide, a nematicide, a toxic emollient, a plant growth regulator, a micronutrient and / or a fertilizer).

To achieve the embodiment of the seedling mat of the present invention, the rooting reconstitution component is cut to the required size (if necessary). If an integrated root barrier structure is not used, the root can be placed, for example, in a plastic tray. Alternatively, no rooting barriers are used. Thereafter, a seed adhesive, preferably a hot melt adhesive, is applied to the root component (e.g., by spraying) and the pretreated (rice seed) is dispersed on the rooting material. Optionally, the coating adhesive is sprayed on / onto the seed. Thereafter, the seed cover component is applied onto the seed. The top cover adhesive may then be sprayed onto the top surface of the seed cover component and, if desired, the top cover. Thereafter, the mat remains dry prior to storage or use.

Thus, in another aspect, the present invention provides a method of preparing a seed mat as described herein,

(a) coating one surface of a planar root material with seed adhesive, wherein the seed adhesive is preferably a hot melt adhesive;

(b) seeding the seed on the adhesive coated surface of the rooting reconstitution component;

(c) applying a seed cover component over the top of the seeded seed, wherein the seed cover component is self-supporting and comprises an organic material compressed into the self-supporting layer, wherein the organic material is selected from the group consisting of coir, Gum, and gaseous impurities.

Once assembled, the dried mat can be stored or used to grow the seedlings / greenhouse seedlings more quickly. After that, the mat with the settled seedlings can be transplanted into the field (rice field). Typically commercial machinery is used for seedling transplantation, and the process allows a small "plug" of the mat to also be implanted.

Various aspects and embodiments of the present invention will now be illustrated in greater detail in the drawings by way of example. It will be understood that modifications may be made without departing from the scope of the present invention.

Example

Example 1: Use of hot melt adhesive as a seed adhesive in seedling mat

The suitability of three different types of hot melt adhesives as seed binders for seed mat was investigated and compared to control seed adhesives such as PVOH E3433CTM (Scott Close, Walworth Industrial Estate, Averover, Hampshire, SP10 5NU, Adhesive).

Of 1.5 cm of 58 cm x 28 cm with a thickness vertical-scan peonhyeong Stone wool Grodan (Industrieweg 15, 6045 JG Roermond , PO Box 1160, 6040 KD Roermond, The Netherlands Rockwool BV (Rockwool ®) material) it was obtained from , A handheld perforator (manufactured by Bronford, Perforation Machinery Ltd., Bradford, UK, with 1353 bronze pins arranged on a bronze cylinder, each pin having a height of 13 mm, And each pin has a diameter of 1.02), the perforator was pushed down on the stone wool to form two passes over the entire surface, to a depth of about 0.5 to 1.0 cm.

Following perforation, each stonewool mat was placed in a black plastic tray (approximately 30 x 60 x 3.0 cm in size) with one tray per treatment.

In the case of Processes A to L, a hot melt adhesive was applied to the upper (perforated) surface using the ITW Dynatec DDS Delta Fx (TM) Fibrous Spraying Applicator using the parameters described in Table 1 below.

Using a conveyor belt, the roots were passed under the ITW Dynatec DDS Delta Fx ™ Fibrous Spray applicator at a rate suitable to achieve a hot melt adhesive application rate of 5 g / m 2 or 20 g / m 2. The hot melt adhesive was applied to the perforated surface. Root rebuilds were prepared using three different hot melt adhesives, Sealock H1125 / 26 ™, Sealock H1155 ™, and Power Bond D74 ™, using this method.

For the control, PVOH E3443C ™ glue was applied across the upper (perforated) surface of the stone wool using a handheld Graco Easymax battery-operated atomizer with 310 nozzles for 10 seconds at a rate of 5.33 g glue per second Lt; / RTI >

For each treatment, 150 g of IR64 rice seeds were evenly sprayed on top of the seed adhesive to provide a seed density of approximately 4 seeds / cm2. This resulted in the application of a layer of PVOH E3443C (TM) glue as a coating adhesive (evenly applied for 2 seconds at a rate of 5.33 g / sec) before applying 25 g of filtered coir. A further layer of coated adhesive (PVOH E3443C ' glue, uniformly applied for 2 seconds at a rate of 5.33 g / sec) was applied over the first layer of coir and a second layer of 25 g filtered coir was applied over . A final layer of PVOH E3443C (TM) glue was applied over the second layer of coir as a top cover (4 seconds applied, 5.33 g / sec)

It can be seen that the treatments A to L were composed of 42.67 g of aqueous glue as compared to the control group consisting of 85.33 g of aqueous glue. Thus, the use of a hot melt adhesive as a seed adhesive halves the moisture content of the assembled seed mat.

The seed mat is carried in the greenhouse and placed in a bay set at the following conditions: day temperature of 28 ° C, night temperature of 18 ° C, light period of 14 hours, relative humidity of 70%. All mats were immediately watered by overhead watering and also by flooding the tray with tap water until the water surface was just below the top surface of the stone wool layer. Water was drained from the tray after 20 minutes. After that, all mats were watered every other day using this method.

The seed mat was grown in the greenhouse for a total of 12 days. The seedlings reached growth stage 3.4 and were visually evaluated for the criteria described in Table 2 below.

Seed mats made using all three hot melt adhesives and control water-based adhesives as seed adhesives were equally well-supported in supporting healthy seedling and root growth. Seedlings grown on a mat with seed glue as a hot melt adhesive showed lower root lift than the control. Rooting is a case in which roots do not penetrate into the rooting material (stonewool) but grow on its surface instead, causing rice seeds to grow and thus cause uneven growth.

Example 2: Large scale preparation of rooting component

Vertical-spun stonewalls of 58 cm x 28 cm size and 1.5 cm thick were obtained from Grodan (see above). The root material was perforated to a depth of approximately 0.5 to 1.0 cm using a handheld perforator (as before) by pressing the perforator down on the stone wool to form two passes over the entire surface.

Using a conveyor belt, the roots were passed under the ITW Dynatec DDS Delta Fx (TM) Fibrous Spraying Applicator at a rate of 5 m / min to achieve a hot melt adhesive application rate of 5 to 7 g / m 2. Root rebuilds were made with three different hot melt adhesives using the conditions described in Table 3 below.

Following application of the adhesive, a sheet of silicone paper was laid on the adhesive-coated rootstock. The rooting component was then packaged and transported to the pond for assembly of the complete seedling mat.

The use of a relatively high application temperature with relatively low air pressure provides an open web spray pattern of hot melt adhesive to maintain optimal wicking / permeability within the rooting material during subsequent use It has been revealed that it has.
