Description

The present invention relates to a planting cocoon and a method for growing plants such as flowers, trees, vegetables using the planting cocoon.

A planting basket is a container for putting soil in order to grow plants. Examples of conventional planting pots include pottery container pots, unglazed pots, concrete pots, plastic pots, and wooden pots. One of the plant growing methods is a method of growing using a planting basket.

There are the following problems in the conventional planting pot. Pottery planting pots are not permeable and water retentive, are almost impossible to repair when damaged, require high-temperature firepower during production, and are difficult to produce in large sizes due to the heating furnace . As with pottery, unglazed planting pots are almost impossible to repair when damaged, and require high-temperature heating power during manufacturing, and it is difficult to manufacture large-sized ones because of the heating furnace. A concrete planting pot has a problem that it has little water permeability and water retention. Plastic planting ridges have no water permeability and water retention, are almost impossible to repair when damaged, and have poor weather resistance. In addition, there is a problem that wooden planting baskets have poor durability. And also in the growth of the plant using each planting basket, the fault which each planting basket has becomes a problem.

A device for improving each defect has been devised. For example, a flower pot using a cork material that is breathable, lightweight and excellent in degradability in soil has been proposed.

The object of the present invention is to improve some of the disadvantages and problems of conventional planting baskets, and in particular to provide planting baskets that are inexpensive and easy to make, have water permeability and water retention. It is. And the other objective of this invention is to provide the method of growing a plant using such a planting basket.

In order to achieve the above-mentioned object, in the present invention, as described in claim 1, a planting basket characterized in that plaster is used as a constituent element is formed. Further, constituting the planting栽枡, characterized in that the plaster components containing fertilizer components. Further, constituting the planting栽枡, characterized in that a component a plaster containing the plant oil. In order to achieve the other object, the present invention, by using a plant栽枡to component lacquer Eating, constitutes a method characterized by growing plants. Further, by using the plant栽枡to plaster components containing fertilizer components, constituting the method characterized by growing plants. Further, by using the plant栽枡to component a plaster containing the plant oil, constituting the method characterized by growing plants. Furthermore, this invention comprises the planting kit creation kit which combines the package which accommodated soil, slaked lime, and the straw separately as essential as described in Claim 7.

By using plaster as a constituent element, it becomes possible to provide a planting pot that is inexpensive and easy to make and has water permeability and water retention. It is possible to provide a method for growing a plant by growing the plant using the planting cocoon.

The present invention is characterized by a planting jar characterized by including a plaster as a constituent element, and preferably a planting cocoon containing a fertilizer component. Here, the plaster is basically a mixture of powdered material and the like in slaked lime, kneaded with water and hardened. As what is blended with slaked lime, there are soil, funori, bitter juice, string waste, straw, clay and the like. This kneaded product solidifies when left in a mold. In the present invention, not only such plaster, but also various types of additives are added to improve and improve various properties.

Further, in the present invention, the planting basket includes not only those that can move like a flower pot but also, for example, a real estate type planting basket installed on a rooftop of a park, a sidewalk, a garden, or a building.

In the present invention, fertilizer that is used together with plaster, preferably mixed with plaster, is not particularly limited, but as fertilizer that can be usually used, nitrogenous fertilizer, phosphate fertilizer, potash fertilizer, organic fertilizer, composite There are fertilizers, calcareous fertilizers, siliceous fertilizers, mafic fertilizers, manganese fertilizers, trace element compound fertilizers, boron fertilizers and the like. In particular, lime nitrogen (CaCN2), which is one of nitrogenous fertilizers, is harmful to plants as it is, and is therefore suitable for the present invention because it is mixed in planting straw, slowly decomposed and used in plants. .

In the present invention, for example, vegetable oil such as sesame oil, rapeseed oil, and sunflower oil can be mixed with the plaster to prevent damage caused by freezing of planting pods. As shown in Example 5, as a result of an experiment of freezing in a freezer, planting pods containing vegetable oil are less affected, while those not containing vegetable oil tend to collapse.

The present invention can also be provided as a kit for creating planting pots such as flower pots. In other words, it is a planting kit making kit in which packages containing soil, slaked lime and straw separately are combined as essential. In addition to the essential package, for example, a package such as furin, clay, fertilizer, etc., or a saddle-shaped frame member may be combined. Thus, by making a plaster material into a kit, anyone can make a plaster planting pot according to their preference.

Another aspect of the present invention is a plant growing method characterized by growing a plant using a planting pot containing plaster as a constituent element, or preferably a planting pot containing a fertilizer component. . There is no restriction | limiting in particular as a plant, For example, a flower, a tree, and vegetables are mentioned. In the present invention, plant growth includes, for example, potting planted plants and ornamental plants in planting pots, and maintaining and managing them.

An example of a planting basket according to the present invention is shown in FIG. (A) of FIG. 1 is a top view of a planting basket, (b) is AB sectional drawing of (a) of a planting basket. This planting pot is composed of plaster 1. In using this planting cocoon, soil is put in the cocoon interior 2 and plants are grown using the soil. To produce the planting pot shown in Fig. 1, prepare inner and outer boxes of different sizes, fit the inner box into the outer box, fill the gap between them with water and add plaster that has been made fluid. After solidifying, remove the inner box, and then take out the plaster in the shape of a planting basket from the outer box. The planting pot concerning this invention can be manufactured by the above operation. The soil can be put into the planting pot interior 2 and plants can be grown with the soil.

As described above, the planting basket according to the present invention can be manufactured at low cost. Moreover, since the shape can be changed freely, various designs are possible. In addition, the planting basket according to the present invention can be crushed and returned to the soil after use, and can be reused. Furthermore, control of water permeability and water retention can be easily performed by selecting a material mixed in the plaster. In the unlikely event that the planting basket is damaged, it can be easily repaired by filling the damaged part with new plaster. Moreover, this planting cocoon possesses sufficient drought resistance and durability.

The feature that the planting pot according to the present invention is greatly different from the conventional planting basket is that the plaster used as a constituent material has a fertilizer effect. Slaked lime, which is an essential component of stucco, and calcium carbonate produced by the reaction of slaked lime with carbon dioxide in the air have an effect as a calcareous fertilizer, and act on the plant as a fertilizer. Furthermore, when the plaster contains bitter juice, the magnesium compound in the bitter juice has an effect as a mafic fertilizer and has a positive effect on the plant.
Thus, the planting basket according to the present invention has not only a function as a planting container but also a preferable fertilizer effect for plants.

In the plant growing method using the planting basket of the present invention, a plaster planting basket having a low bittern content and easily releasing water is suitable for growing cactus, bento grass, geranium, and the like. In addition, the stucco cocoons having a high bittern content and hardly release water are suitable for growing plants that are vulnerable to acidic soil, such as sweet pea, calendula, gypsophila, German iris, lavender and the like. Furthermore, the stucco cocoons having a high bittern content and hardly releasing water are suitable for growing plants that are vulnerable to drying, such as primula, pansy, hydrangea and gentian.

When planting pots are placed directly on concrete in the summer, the temperature of the soil rises, and troubles such as plant dying tend to occur. When placed directly on the substrate, the temperature reduction effect is remarkable compared to other materials.
This is presumably because the heat of vaporization is the reason for the reduction in temperature, but plaster is superior in water retention compared to other materials, so in other materials, excess water that the soil cannot retain can be discharged from the fence. On the other hand, in the case of plastered cocoons, the cocoons are more excellent in water retention than the soil, and the temperature reduction effect due to water evaporation is considered to be sustained.

Moreover, when installing the plaster planting jar of the present invention on the rooftop or outdoor space, it is possible to perform on-site construction in which a planting cocoon is made even on a large planting jar. In addition, if many small planting baskets are arranged, the surface area of the planting basket can be greatly increased. The radiator function increases the effect of lowering the rooftop temperature, for example, and is effective for rooftop greening and rooftop temperature reduction. Hereinafter, the present invention will be described in detail by way of examples.

  Table 1 shows the composition of the plaster for examining the mechanical strength of the plaster.

The circles in Table 1 indicate the components contained in each sample from sample SA-1 to sample SE-1 and the mixing ratio of soil to lime. The ratio of soil: lime is 10: 1-3: 7. FIG. 2 shows the bending strength of each of these plaster samples, and FIG. 3 shows the compressive strength. As for the ratio of soil and lime, 7: 3 showed high bending strength and compressive strength. When the amount of bittern was increased, the strength further increased (SB-1). As mentioned above, when it sees from an intensity | strength surface, the mixing | blending which increases a bittern to soil: lime = 7: 3 is preferable.

In Table 2, the composition composition of the stucco component of the planting pot made of stucco for examining water permeability and water retention was shown. The thickness of the ridge was 3 cm.

The circles in Table 2 indicate the components contained in the samples PA-1 to PE-1 and the mixing ratio of soil to lime.

FIG. 4 shows the change over time in the volumetric water content of each planted cocoon produced with this composition. In this case, the planting pot is installed on a plastic table and does not touch the soil. For comparison, the values of a concrete planting basket and a plastic planting basket were also shown. The concrete and plastic planting pots were slowly reduced in moisture. On the other hand, the stucco planting pot has a large reduction in moisture compared to the concrete and plastic planting pots. This is because, in concrete and plastic planting pots, there is almost no water permeability. This is because moisture can evaporate from the water.

FIG. 5 shows the time-dependent change in the volumetric water content when the bottom surface of the plaster planting pot having the composition shown in Table 2 is grounded. The earth to be grounded is in a large plastic container. In FIG. 5, on the third day, the grounded soil was replenished with water as a rain simulation. In concrete and plastic planting pots, the volumetric water content decreases monotonously, but in the plastered planting pots, when water is supplied to the grounded soil, the volumetric water content increased. In particular, the increasing tendency of the volumetric water content of the mortar (PB-1) with a plaster composition containing 2% bittern is large. This indicates that the stucco iron has functions of water permeability and capillary action.

FIG. 6 shows the change over time in the volumetric water content when only the bottom surface of the planting basket is made of plaster and the other surface is made of concrete. For comparison, the values of planting pods with all surfaces made of concrete are also shown. When the bottom surface was plastered, the case where it was placed on a plastic table and the case where the bottom surface was grounded were examined. All surfaces made of concrete were grounded.

When all surfaces are made of concrete, the volumetric water content decreases monotonously. In the case where only the bottom surface is made of plaster and placed on a plastic table, the volumetric water content is monotonically reduced more than that made of concrete. On the other hand, in the case where only the bottom surface was formed with plaster and the bottom surface was grounded, the volumetric water content decreased first, and then maintained a constant value. This indicates that the bottom surface made of plaster has a capillary function and has a function of sucking moisture from the ground.

In addition, as shown in the present Example, the planting pot according to the present invention may be one in which the plaster constitutes a part of the planting pot.

The planting jar shown in Fig. 1 is manufactured using plaster mixed with fertilizer substances. In addition to the characteristics made of stucco, the planting basket manufactured in this way can express any fertilizer effect by selecting the fertilizer to mix. Fertilizers that can be used include nitrogenous fertilizer, phosphate fertilizer, potash fertilizer, organic fertilizer, composite fertilizer, calcareous fertilizer, siliceous fertilizer, bitter soil fertilizer, manganese fertilizer, trace element composite fertilizer, boron fertilizer, etc. is there. In particular, lime nitrogen (CaCN2), which is one of the nitrogenous fertilizers, is harmful to plants as it is, so it is mixed in straw, slowly decomposed and used in plants, so it is suitable for this use.

Planting straws having the composition shown in Table 3 were prepared. As the vegetable oil, rapeseed oil was used. The obtained planting straw (sample) was placed in a freezer at -5 ° C for 2 days, and an experiment was conducted to examine the state of breakage due to freezing. The results were as shown in Table 3. The results showed that the sample with vegetable oil had less influence, whereas the sample without vegetable oil was more likely to collapse.

The temperature change in the soil in the plaster planting basket, plastic planting basket, unglazed planting basket and mortar planting basket of the present invention, when the planting basket is grounded to concrete, and when not grounded Compared. The results are shown in FIG. 7 and FIG. 8 (in the figure, “earth plaster” represents the planting pot of the present invention). In either case, as compared with the plantation basket made of other materials, the plaster plantation basket of the present invention has the lowest soil temperature.
