Description

  The present invention relates to a growing tool capable of growing plant seedlings in a short period of time, a short-term growing method using the tool, a plant seedling set for planting, and a seedling method using the plant seedling set. In more detail, the present invention can be applied to planting seedlings in areas where plant growth is difficult, such as dry land, cold regions where the soil surface is frozen, and salt accumulation regions where salt is accumulated on the soil surface. The present invention also relates to a short-term growing tool that can be grown in a short period of time, a short-term growing method using the tool, a plant seedling set for permanent planting, and a seedling method using the plant seedling set.

  As is well known, the moisture content in the ground in dry land is very small compared to the moisture content in other zones where greening is easy. For example, as a result of measuring the moisture content in soil in Nigeria, Africa, in 2000 with respect to soil depth, a relatively stable moisture content was observed at a depth of 30 cm or more, compared to the fact that the soil surface has almost no moisture content. It was. Thus, the survival of plants in dry land depends on how fast roots can reach this deep layer of stable water content.

  Moreover, in the salt accumulation soil widely distributed in the world, it is often that a relatively shallow portion of the soil (from the surface to a depth of 20 to 30 cm) contains a large amount of salt, and the moisture content of the portion is high. Even if it is the quantity which enables plant growth, the growth will be inhibited by the salt.

  Conventionally, as a technique for growing a plant in the dry zone as described above, for example, a structure (Patent Document 1) as shown in FIG. 9 or a structure (Patent Document 2) as shown in FIG. 10 is used. It has been proposed.

  The method for growing plants using the structure shown in FIG. 9 is as follows. That is, after mounting the outer cylinder member 1 in the space X having a required cross-sectional area and depth formed by excavation, and filling the outer cylinder member 1 with soil S1 containing a water retaining material, the center portion thereof After placing the inner cylinder member 2 filled with soil S2 for vegetation containing a water retention material in the gap formed in the water, irrigating each soil S1, S2, and holding the sufficient water in the existing water retention material, Planting seedlings or seedlings in the soil S2 in the inner cylinder member 2 and blocking the outflow of moisture in the soil S1 to the outside of the outer cylinder member 1 by the outer cylinder member 1, and the inside of the inner cylinder member 2 by the soil S1 The soil S2 is insulated from the geothermal heat, and the plant is grown while keeping the soil moist by preventing the soil from being cooled and dried.

  In addition, as measures against drying and salinity, efforts are made to increase the fixing rate by selectively using plant species having drought resistance and salt resistance. Furthermore, even in a region of dry soil with a lot of salt, when there are abundant water sources nearby, attempts have been made to wash away the salt from the soil using the water.

  Moreover, when using a seedling as a form of the growing plant, the seedling is currently produced by pot cultivation or outdoor cultivation.

  The structure of FIG. 10 includes a cylindrical outer layer 5 formed of a biodegradable material, a cylindrical intermediate layer 6 having water retention and water absorption, and an inner layer 7 made of soil mixed with fertilizer. It is configured. The upper surface and the lower surface of the intermediate layer 6 are covered and protected by a thin disc-shaped upper lid 8 and lower lid 9 made of the same material as the outer layer 5.

  Using the structure of FIG. 10, a method for growing a plant on a dry land, a sand dune, a desert, or the like is performed by first connecting a plurality of soils to a length that reaches a soil base having underground water at the bottom of a sandy land such as a desert. Boring is embedded and seeds or seedlings are planted in the inner layer 7. After seedling establishment, about 1 liter of water is poured once every 30 days until the roots reach the soil base.

JP 2000-032840 A Japanese Patent No. 3811801

  By using the technique described in Patent Document 1, high water retention and inhibition of root elongation due to high temperature can be suppressed. However, since the technique described in Patent Document 1 has a complicated structure and a complicated work such as replenishment of a water retaining material to a culture medium, a great amount of labor is required for a series of operability. Moreover, since continuous water supply to the plant has to be performed by drip irrigation etc., there are further improvements such as loss of water due to evaporation although it is small.

  In addition, the dry land planting measures that use plant species that are strong in salinity are actually very high in salinity, and even if plant species that are strong in salinity are used, there is a high possibility that biological damage will occur. Difficult to fix.

  In addition, the method for washing and removing the salt in the soil used when there are abundant water sources nearby is not practical because such a water source cannot be secured in dry land.

  Further, in pot cultivation and open field cultivation used as a method for preparing seedlings used for fixed planting, the seedling raising period is long.

  The structure disclosed in Patent Document 2 is directly embedded in sand such as dry land that is difficult for plant seeds and seedlings to settle. After the implantation, plant seeds or seedlings are planted in the inner layer 7. Then, water is supplied from above the structure to replenish water to the plant seedling. The inner layer 7 is soil mixed with fertilizer, and when it contains moisture, it becomes a nutrient source for plants and a supply source of moisture.

  According to the experiments by the present inventors, when a plant is grown using the structure and plant fixing method disclosed in Patent Document 2, it reaches underground water at a depth of 30 cm or more from the surface of the sand. Until then, plant roots could not be grown. When the cause was sought, the inner layer 7 where plant seedlings are planted contains fertilizer and given sufficient moisture, so the plant has many short roots that branch off to obtain nutrients and moisture from the inner layer 7 It has been found that long roots do not grow until reaching underground water located below 30 cm. Therefore, according to the structure and the plant fixing method disclosed in Patent Document 2, it is difficult to fix a plant on a dry land, and even if possible, it takes a long time for fixing, and during that time, water is constantly poured. As a result, the amount of water required for establishment becomes enormous, and the planting business is forced to fail in terms of cost.

  On the other hand, the present inventors have made it difficult to use the water on the soil surface such as dry land, cold region, and surface salt accumulation area (it is difficult to secure the water necessary for plant growth) in the local soil. In order to establish a technology that can plant seedlings smoothly and establish seedlings and grow them without needing to artificially replenish water in a fixed planting area, intensive studies, experiments, and examinations are repeated. It was.

  As a result, before planting in an actual planting site such as a desert, the length that can reach the subsurface hydrous layer of the planting plant is set under an appropriate environment different from the planting plant as shown in FIGS. The artificial soil has a hardness that allows the plant seedling 11 to be fixed inside the upper opening 10a of the cylindrical body 10 and to increase the growth rate of the root of the plant seedling 11 below the inside of the cylindrical body 10. It has been found that a plant seedling 11 having a long root 11a can be obtained by filling the growth material 12 such as the above and promoting the growth of the root of the plant seedling 11 downward of the cylindrical body 10. The hardness of the growing material 12 may be set to be equal to or lower than the soil hardness of the fixed plantation where the plant seedling after growing is to be fixed. Preferably, the growing material 12 does not fall off the inner wall 10b of the cylindrical body 10. It is better to fill it as low as possible. And since hydration does not perceive the necessity that the root of a plant extends long downward according to the water injection from the upper part of the growth material 12, only the lower end part of the cylinder 10 is immersed in water intermittently so that the plant seedling It has also been found that if a load is applied to 11 to sense the necessity of extending the root downward, the growth of the long root 11a can be realized. In addition, when water is poured onto the growth material 12 in the cylinder 10 from above the cylinder 10, the growth material filled in the cylinder 10 at a low density is likely to drop off. It was confirmed that water replenishment utilizing the water absorption of the material of the cylinder 10 and the growth material was preferable from the bottom.

  As described above, if the long root 11a grows until it reaches the lower end of the cylindrical body 10 and further extends downward from the lower end of the cylindrical body 10, the long root 11a is The plant seedlings are transported to the planting site together with the cylinder 10 that supports the growth, and are inserted into the bored hole (arriving at the underground hydrous layer) of the planting site together with the cylinder 10 and embedded. At the time of embedding, the long roots 11a of the plant seedlings 11 accommodated in the cylinder 10 immediately come into contact with groundwater suitable for plant growth and begin to absorb moisture. As a result, the establishment rate of the planted plant is greatly improved, and water injection from the ground surface is almost unnecessary, so that the cost for subsequent plant growth can be greatly reduced.

  The inventors of the present invention integrally integrate a cylinder (short-term growth tool) in which a growing material is filled with a predetermined hardness, a plant seedling having a long root grown in the cylinder, and the cylinder. By distributing the plant as a plant seedling set, the plant seedling can be transported to a planting site in the desert without damaging the plant seedling, and planting (planting) on the planting site can be performed easily. It was confirmed at the medium-scale production level that the fixing rate can be remarkably improved.

  After establishing such a series of techniques, that is, a plant root short-term growing tool, a growing method, a plant seedling set, and a planting method for obtaining a plant seedling having a long root that can be established in a fixed planting site, the present invention Furthermore, they decided to consider the points that should be improved for the training process in this technology.

  As a result, in the growing process, if you can know from time to time where the growth end of the root of the plant seedling is located in the cylinder, and whether there is no filling failure such as dropout or bias in the growing material, Irrigation location, irrigation interval, amount of irrigation can be optimized, and reconditioning of the growing material can be performed before the root is damaged, greatly reducing the failure rate in plant seedling production It was discovered.

  The present invention has been made in view of the above circumstances, and the problem is that in the growing process of plant seedlings in which long roots are grown in a short period of time in the growing material in the cylinder, the state of the growing material in the cylinder and the plant seedling An object of the present invention is to provide a plant seedling growing tool and a growing method for plant seedling, a plant seedling set for planting, and a planting method that can confirm the tip position of a growing root at any time.

By these, the failure rate in the production of plant seedlings can be greatly reduced, and plant seedlings with long roots suitable for fixed planting land with high-quality hydrous soil layers such as deserts can be efficiently produced in a short period of time. it can.

  Hereinafter, examples of a plant seedling short-term growing tool and a growing method, a planting seedling set for planting, and a planting method in a planting site according to the present invention will be described in detail with reference to the drawings. In addition, the Example shown below is only the illustration for demonstrating this invention suitably, and does not limit this invention at all.

  FIG. 1 is a diagram for explaining a first embodiment of the present invention and is a diagram showing a configuration of a plant seedling short-term growing tool according to the present invention. The purpose of using this short-term growing tool is, firstly, in areas where it is difficult to grow plants such as dry land, salt is often present in the shallower layers from the ground surface. When irrigation is carried out using water that contains water, salt accumulation occurs, and the amount of water necessary for plant growth cannot be obtained without reaching the deep soil layer. It is to nurture plant seedlings having long roots that can be reached. Secondly, it is possible to confirm the state of the growing material in the cylinder for growing the plant seedling and the growth tip position of the root of the plant seedling at any time.

  For that purpose, the short-term growing tool 20 of the first embodiment includes a cylindrical body 21 in which a part of the side surface of the cylindrical member is cut out in the longitudinal direction, and a cut-out opening in the cylindrical body 21. A transparent lid member 22 for closing the portion, and a growing material 12 for plant seedlings filled in the cylindrical body 21 whose opening is closed by the transparent lid member 22.

  As shown in FIG. 2, a plurality of partition walls 23 are attached in the cylindrical body 21 with a predetermined gap between the transparent lid member 22 and a predetermined interval in the longitudinal direction. .

Within the cylinder body 21, the growth material 12 maintains a hardness that allows the growth rate of the plant seedlings 11 to be fixed to the inside of the upper opening of the cylinder body 21 to increase the growth rate below the roots. It is filled to such a density. The hardness of the growing material 12 in the cylindrical body 10 is adjusted to be equal to or lower than the soil hardness of the fixed plantation. When the hardness is expressed by a known dry density, in soybean, when the fixed soil hardness is 1.5 Mg · m ⁻³ , if the soil hardness is adjusted to 1.35 Mg · m ⁻³ , the elongation rate below the roots is increased. (as compared with the planting soil hardness (= 1.5Mg · m ^-3)) may be increased to more than double, by adjusting the soil hardness below 0.5Mg · m ^-3, downward roots Can be increased 5 times or more (compared to the case of fixed soil hardness (= 1.5 Mg · m ⁻³ )). That is, it is preferable that the hardness of the growing material 12 in the cylindrical body 10 is as low as possible.

  For the purpose of reducing the hardness of the growing material 12 as much as possible, the partition wall 23 provided in the cylindrical body 21 serves to hold the growing material 12. That is, even if the filling density of the growth material 12 is lowered by the partition wall 23, the growth material 12 can be prevented from falling off, and the purpose of reducing the hardness of the growth material 12 can be achieved.

  Further, when the long root 11a of the plant seedling 11 grows and approaches the partition wall 23, it goes toward the gap between the partition wall 23 and the transparent lid 22 in order to avoid the partition wall 23 and grow further. It grows and extends further downward through this gap. Therefore, by observing the portion where the partition wall 23 in the cylindrical body 21 is provided through the transparent lid member 22, the growth tip position of the long root 11a can be confirmed as needed. Further, since the state of the growing material 12 in the cylindrical body 21 can always be observed by the transparent lid member 22, it is possible to know in advance that the growing material 12 is dropped and root growth is hindered. And appropriate readjustment processing can be performed.

  In addition, in the said Example 1, although the cylinder main body 21 was made into the half shape, the perfect cylinder was notched in the 2-30% length direction, if it says, 80% of the cylinder was left, and 70% was left. Another embodiment of the present invention is also possible in which a shape is formed and a notch opening portion in the longitudinal direction is closed with a lid material so as to be opened and closed.

  A second embodiment of the present invention is shown in FIGS. As shown in the figure, the short-term growing tool 30 according to the second embodiment is characterized in that at least two halved half cylinders 33a and 33b that form a continuous cylinder when the opening sides are overlapped with each other. A half-coupled body 33 in which the side edges of the half-coupled body 33 are refractably coupled, the plant seedling growing material 12 filled in the half-cylindrical bodies 33a and 33b of the half-coupled body 33, and the half It is in the point which has the inclination fixing means 31 which inclines and fixes the split connection body 33 by a predetermined angle, and the transparent lid | cover material 34 which covers the opening part of the said half connection body 33 so that opening and closing is possible.

  The half-coupled body 33 is preferably composed of a large number of half-cylindrical bodies 33a and 33b in order to increase productivity. It is important that the numbers 33a and 33b are provided as a set, and the total number is an even number.

  Further, a plurality of partition walls 35 are attached to the half cylinders 33a and 33b with a predetermined gap between them and the transparent lid member 34 with a predetermined interval in the longitudinal direction.

  The inclination fixing means 31 for supporting and fixing the half-coupled body 33 having the above-described configuration in an inclined state has an inclined plate 32, and the inclined surface of the inclined plate 32 supports the entire lower side surface of the half-coupled body 33. Thus, the half connector 33 is prevented from being bent or bent. The inclination angle of the inclined plate 32 is set to 30 to 75 degrees. When the inclination angle is 30 degrees or less, which is the lower limit value, the downward extension of the roots of the plant seedling 11 starts to be blunted. In addition, if the inclination angle is 75 degrees or more, which is the upper limit value, it is not preferable because the internal growth material easily falls off.

  As a material constituting the half-connected body 33, a material having water permeability, water retention, and air permeability is preferable. As such a material, inorganic and organic porous materials can be used. Examples of the inorganic porous material include a porous sintered body obtained by sintering sludge dry particles, and examples of the organic porous material include a hard foam of synthetic resin. Further, as will be described later, when the plant seedling 11 is actually planted, the half-coupled body 33 is left in the soil together with the plant seedling 11, so that it decomposes with time and becomes part of the soil. Biodegradable materials are preferred. This is also for the purpose of preserving the environment and for preventing the plant seedling 11 from becoming a constraint when it grows thick.

  The growing material 12 is made of a material having water permeability, water retention, and air permeability so that moisture and oxygen can be supplied to the roots of the plant seedling 11. Examples of such materials include soil, sand, gravel, vermiculite, perlite, sponge-like synthetic resin, and the like.

  As the transparent lid member 34, any one of a transparent plate member, a transparent sheet member, and a transparent film member made of a transparent plastic material can be used. Since the half linking body 33 is fixed in an inclined state by the inclination fixing means 31 and the inner growth material 12 is stably held, the transparent lid member 34 mainly evaporates the moisture of the growth material 12. In order to prevent this, a simple attachment method of simply mounting on the half-connected body 33 may be used.

  A short-term growing method of a plant seedling for obtaining a plant seedling having a long root that can be settled in a fixed planting area using the short-term growing tool 30 of the second embodiment is a plurality of half-halves constituting the half-coupled body 33. Each other of the split cylinders 33a, 33b,... Is fixed by growing the plant seedling 11 in the growing material 12 inside the upper end thereof, and growing the root of the plant seedling 11 downward, thereby extending the length. A plant seedling having a root is obtained.

  In this short-term growing method, the growing material in the half cylinder and the state of the growing root can be observed through the transparent lid. In that case, it is observed through the transparent lid member 34 that the root 11a of the plant seedling 11 has crossed the partition wall 35 provided in the half cylinder 33b on which the plant seedling 11 is planted.

  In the plant seedling short-term growing method using the short-term growing tool 30 according to the second embodiment, the half-coupled body 33 that is fixed by being inclined at a predetermined angle by the inclination fixing means 31 remains fixed. It is possible to temporarily remove the transparent lid material 34 that covers the upper surface and open the upper side surface, thereby supplying moisture directly to the inner growth material 12.
