DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plant seedling planting structure, a planting method, and a plant seedling planting structure in a planting apparatus capable of easily and quickly planting a plant plant, a flower or other plant seedlings.

BACKGROUND OF THE INVENTION

[0002] When a plurality of plants are planted in the vicinity of a building such as a park or a building and the places are greened, conventionally, seeds are sown on the planned greening area and grown or grown elsewhere. It is done by such means as planting seedlings. However, when seeds are cultivated and cultivated, it is necessary to plant the cultivated seedlings in many situations, because the subsequent management is complicated, not to mention germination.

[0003] When greening a predetermined area using seedlings, seedlings grown to a predetermined size in a dedicated nursery field are planted in the greening area, and the number of seedlings in the greening area corresponds to the number of seedlings. It is necessary to form a hole and bury each seedling in this hole, and such a work is inevitably very complicated. In other words, depending on the type of spot, some 60 seedlings need to be buried in a one-square-meter greening area, so it can be used in vast greening areas such as parks and buildings. On the other hand, embedding such plant seedlings requires extremely complicated work.

A plurality of seedlings to be embedded need to be arranged at regular intervals in consideration of aesthetics, and it is often necessary to arrange the seedlings in an arc shape or the like for design reasons. In such a case, as a pre-process for forming a hole for filling the seedling, a preparation operation such as marking a hole forming position in advance was necessary. On the other hand, in recent years, attempts have been made to plant plants on the rooftop of a building, etc., and to green an inorganic space in an urban area. Therefore, the applicant of the present application has disclosed a lightweight planting apparatus having excellent water retention and drainage properties. (See, for example, Japanese Patent No. 2531542)

[0005] By the way, when greening the rooftop of a building or the like, it is required to shorten the construction period as compared with the work associated with greening of the land such as a park or a building. That is, when greening the rooftop of a building, etc., the users of the building will be directly damaged by the noise and vibrations caused by the construction work. You.

[0006] On the other hand, this planting device is used for a rooftop of a building or the like.
Although it is often provided at a high place, in such a high place, an irregular wind is always generated. However, since the seedlings planted in the planting equipment do not have sufficient rooting, it is necessary to hold the seedlings from above with a protective net or the like as a measure against this wind. However, if a protection net or the like is set on the planted seedling as it is, the seedling will be damaged, so that when installing the protection net or the like, a complicated work of passing a protective net or the like for each seedling must be performed. You.

DETAILED DESCRIPTION OF THE INVENTION

An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a view showing one embodiment of a plant seedling planting structure according to the present invention. In the figure, reference numeral 1 denotes soil in a planned greening area around a park or a building, the surface of which is leveled flat. Numeral 4 is a plant seedling to be planted in the soil 1. The plant seedling 4 is grown in a dedicated nursery field to a predetermined size using a seedling raising tray described later. The plant seedling 4 includes a root portion 2 having an earthen mass containing nutrients necessary for growing the plant, and a frame portion 3 extending from the root portion 2.

The shape of the root 2 of the plant seedling 4 is
As shown in FIG. 1A, the width in the vertical direction, which is the growth direction of the skeleton 3, is larger than the width in the horizontal direction perpendicular to the skeleton 3. In addition, this plant seedling 4
Is formed in a conical shape so that the cross-sectional area decreases toward the tip. When plant seedlings 4 are to be planted on soil 1, any one of side surfaces 2b and 2b of root 2 of plant seedlings 4 is brought into contact with the surface of soil 1 as shown in FIG. And plant seedling 4
As shown in (a), the plant is planted in a state of lying down.

By the way, the planting work of the plant seedling 4 is as follows.
As shown in FIG. 2, it is possible to perform a simple operation of dropping a required number of plant seedlings 4 at appropriate intervals so as to be sprayed on the surface of the soil 1. Even when planting seedlings 4, the operation can be performed easily and quickly. That is, as described above, the root 2 of the plant seedling 4 is formed in a conical shape such that the width in the vertical direction is larger than the width in the horizontal direction and the cross-sectional area becomes smaller toward the lower side. The upper part of the root 2 is heavier than the lower part, and the bottom of the root 2 is smaller. Therefore, the plant seedling 4 cannot stand on the surface of the soil 1. If the plant seedling 4 is dropped on the surface of the soil 1, the plant seedling 4 naturally contacts the side surface of the root 2 with the surface of the soil 1. And the planting is completed.

FIG. 3 is a partially cutaway perspective view showing a seedling raising tray for growing the plant seedling 4 shown in FIG. 1. The seedling raising tray includes a plurality of pots 6 having the same shape. I have it. The plurality of pots 6 of this seedling raising tray are formed in a truncated quadrangular pyramid shape in which the cross-sectional area in the lateral direction decreases toward the bottom, and in this example, the pot 6 has an opening of 3 mm.
The size is 3 mm × 20 mm, and the bottom portion is 20 mm × 10 mm. That is, the area of the bottom surface is smaller than the opening by one third or less.

The roots 2 of the plant seedlings 4 grown using the pots 6 are formed in a truncated pyramid shape having a smaller cross-sectional area as they go downward. Can be easily pulled out of the pot 6 at the time of transplantation or the like. The height of the bowl 6 is 35 m.
m, which is longer than any side of the opening having a size of 33 mm × 20 mm. The plant seedlings 4 are grown by putting soil, fertilizer, and seeds into the plurality of pots 6 of the seedling raising tray over a predetermined growth period. That is, the plant seedlings 4 are grown until the buds and roots grow to some extent and the transplanting to the soil 1 does not hinder the growth.

The fertilizer to be fed into the pot 6 together with the soil and the seeds is kept until the plant seedlings 4 take root in the soil 1.
The necessary and sufficient amount capable of continuously supplying nutrients is supplied. A soil mass is formed by covering the roots of the plant seedling 4 with the fertilizer and the soil put into the pot 6, and the root portion 2 shown in FIG. 1 is configured by the soil mass and the root of the plant seedling 4. Is done. That is, if the plant seedling 4 in which the buds and roots are grown is pulled out from the seedling raising tray, the root 2
Has a shape similar to the shape of the pot 6 as shown in FIG.
In other words, the root 2 has a truncated pyramid shape in which the width in the vertical direction, which is the growth direction of the skeleton 3, is formed larger than the width in the horizontal direction perpendicular to the skeleton 3, and the cross-sectional area decreases as it goes downward. Formed.

If the plant seedlings 4 are sprayed on the surface of the soil 1 at appropriate intervals, the plant seedlings 4 having the roots 2 whose upper part is heavier than the lower part and whose bottom is smaller than the lower part, The plant is planted in a state in which the side surface 2b of the root portion 2 comes into contact with the surface of the soil 1 and is turned sideways.

By the way, as shown in FIG. 1A, the plant seedlings 4 planted on the surface of the soil 1 seem at first glance to move from the planting position, but there is no danger. That is, the plant seedlings 4 planted sideways are less likely to receive wind pressure as compared to the standing state, and there is no possibility that they will move from the planting position by wind.

The plant seedling 4 planted in the state shown in FIG. 1A grows by absorbing nutrients in the soil mass of the root portion 2 and grows the root 2a into the soil as shown in FIG. 1 is advanced into the soil 1 from the surface. The frame 3 of the plant seedling 4 changes its direction upward. This FIG. 1 (b)
In the state of (1), the plant seedlings 4 are apt to receive the wind by the body part 3 turned upward. However, since the roots 2a enter the soil 1 and the rooting to the soil 1 is progressing,
There is no fear that the plant seedlings 4 will fall down due to the wind. The soil mass of the root portion 2 collapses due to rainwater, supplied water, or the like, spreads over the surface of the soil 1 as shown in FIG. 1B, and gradually assimilate with the soil 1. And FIG.
When the plant seedling 4 further grows from the state of FIG.
As shown in (c), the skeleton 3 is in a vertical state, the soil mass is assimilated with the soil 1, and the roots 2a are deeply advanced to the inside of the soil 1.

That is, the plant seedlings 4 can be rooted on the soil 1 in the same state as the plant seedlings planted in the holes formed in the soil 1. The planting operation of the plant seedlings 4 can greatly improve the work efficiency as compared with the conventional planting operation of plant seedlings. That is, it is possible to omit a complicated operation of forming a plurality of holes according to the number of seedlings in the soil and planting the seedlings therein, and when planting a plurality of plant seedlings 4 in a wide greening area. Even so, the work can be done easily and quickly.

For example, when greening an extremely large site such as a forest, if the site has a gentle slope, a plurality of plant seedlings 4 are stacked on a predetermined transport vehicle, and the transport vehicle is moved slowly. If a plurality of plant seedlings 4 are sprayed so as to be dropped, the planting operation can be efficiently advanced.

On the other hand, when arranging a plurality of plant seedlings 4 at equal intervals or arranging a plurality of plant seedlings 4 in an arc shape, it is possible to omit the preparation work for marking the soil surface. . That is, the position of the plant seedlings 4 placed on the surface of the soil 1 can be easily changed, and the plant seedlings 4 are temporarily set, and the position of only the irregular plant seedlings 4 is adjusted so that a mark is formed on the soil 1. The arrangement of the plant seedlings 4 can be performed without performing.

The root 2 of the plant seedling 4 shown in FIG.
Shows an example in which a truncated quadrangular pyramid is formed.
The shape of the root portion 2 may be any shape as long as the plant seedling 4 cannot stand on the surface of the soil 1 when the plant seedling 4 is sprayed on the surface of the soil 1. That is, even if the shape of the root portion 2 of the plant seedling 4 is frusto-conical or truncated triangular, the same effect as described above can be obtained.

FIG. 4 is a diagram showing another example of the configuration of the root of the plant seedling 4. The root 2 of the plant seedling 4 shown in FIG.
The width in the vertical direction which is the growth direction of the skeleton part 3 is formed larger than the width in the horizontal direction perpendicular to the skeleton part 3, and the cross-sectional area becomes smaller as it goes downward, and the lower end face is formed extremely small. I have. The plant seedling 4 having the root portion 2 cannot be erected on the soil surface similarly to the plant seedling shown in FIG. The plant seedlings 4 having the roots 2 can also be planted in a horizontal state by a simple operation of merely dropping the plant seedlings 4 on the soil surface.

On the other hand, the root 2 of the plant seedling 4 shown in FIG.
Is formed so that the width in the vertical direction, which is the growth direction of the skeleton portion 3, is larger than the width in the horizontal direction orthogonal to the skeleton portion 3. The root 2 is composed of a prismatic upper part 2c and a conical lower part 2d whose cross section in the lateral direction becomes smaller as it goes downward. That is, the plant seedling 4 having the root portion 2 is also unable to stand upright on the soil surface.
The plant seedlings 4 having the roots 2 can also be planted in a horizontal state by a simple operation of merely dropping the plant seedlings 4 on the soil surface.

In order to produce a plant seedling 4 having the roots 2 shown in FIGS. 4 (a) and 4 (b),
The plant seedlings 4 may be grown by a seedling raising tray having a pot having the same shape as the shape of the plant.

Next, application of the above-described planting technique to a planting apparatus described below will be described. FIG. 5 is a cross-sectional view illustrating an example of planting the above-described plant seedlings 4 with respect to the planting apparatus. In FIG. 5, A is a waterproof layer adhered to a concrete slab surface on the roof of a building, and a resin layer is formed on the upper surface of the waterproof layer A to prevent roots of plants from entering the waterproof layer A. A root guard B is installed. C is a drain plate made of resin or metal as water retention / drainage means, and a plurality of water retention portions C1 and drainage portions C2 are integrally formed over the entire surface. D is a guest soil layer on which various plants and the like are planted. A plurality of plant seedlings 4 are planted sideways on the top surface of the guest soil layer D, and a protective net N is placed on the plant seedlings 4. Is stretched.

A planting layer is formed by the soil layer D, the protection net N, and the plant seedlings 4 interposed therebetween and planted on the soil layer D. By the way, such planting devices are often installed on high places such as the rooftops and roofs of buildings, but in such high places constantly irregular winds are generated. The protection network N is provided. And as a material of the protection net N,
Hemp, coconut fiber and other natural fiber materials, viscose rayon, cotton, biodegradable plastics, etc. are used to obtain degradability and corrosiveness in a short period of time. May be used.

Further, the size of the mesh of the protection net N, the degree of steepness, etc. are set so that the plant can grow to a certain stage and the soil of the guest soil layer D can be prevented from being scattered. On the other hand, while protecting, the plant seedlings 4 scattered and placed on the guest soil layer D are secured on the guest soil layer D, and are taken into consideration so that the frame 3 can grow upward through the mesh of the protection net N as it grows. I have. Reference numeral 5 denotes a fixing means, which is formed continuously with the drain plate C, and the top of the fixing means 5 is fixedly joined to the protection net N with screws or the like.

The shape of the root portion 2 of the plant seedling 4 planted in the planting device is similar to that of the plant seedling 4 shown in FIG. It is formed in the shape of a cone such that the width in the vertical direction, which is the growth direction, is large, and the cross-sectional area in the horizontal direction decreases as it goes downward. The plant seedling 4 is placed on the top surface of the soil layer D such that the side surface of the root 2 is in contact with the surface of the soil layer D. This plant seedling 4 can also be firmly rooted in the soil layer D and grow like the plant seedling 4 shown in FIG.

By the way, as shown in FIG. 4, when the roof of a building is greened, it is required to shorten the construction period as compared with the case of greening a land such as a park or the periphery of the building. In other words, when greening the rooftop of a building, etc., the users of the building are directly damaged by noise and vibrations accompanying the construction, so that quick work is required in such places. However, in the planting structure of the plant seedling in the planting device according to the present invention, the construction period can be shortened.

That is, at the time of planting the plant seedlings 4, the plant seedlings 4 are sprayed on the surface of the guest soil layer D at appropriate intervals, so that the roots 2 whose upper part is heavier than the lower part and whose bottom is smaller are provided. The resulting plant seedling 4 does not stand upright on the surface of the soil layer D, but is planted with the side surface 2b of the root 2 in contact with the surface of the soil layer D and laid down. The planting work of the plant seedlings 4 can reduce the working time as compared with the conventional planting work of the plant seedlings. That is, a plurality of holes according to the number of seedlings are formed in the guest soil layer D,
The complicated work of planting seedlings in the holes can be omitted, and even when a plurality of plant seedlings 4 are planted, the work can be performed quickly.

In the planting apparatus according to the present invention, the plant seedlings are planted in a structure in which the plant seedlings 4 are planted sideways, so that the protection net N can be installed easily and quickly. That is, when a seedling is planted by forming a hole in the guest soil layer D as in the related art, if the protection net N is placed on the seedling as it is, the seedling will be damaged. A complicated operation of passing a protective net through each seedling was required. On the other hand, the planting structure in the planting apparatus according to the present invention is such that the plant seedlings 4 are planted sideways, so that even if the protection net N is installed from above the plant seedlings 4, the plant seedlings 4 Is not damaged, and the installation of the protection net N can be performed easily and quickly.
