[0001]
[Technical field to which the invention belongs]
The present invention relates to a seedling pot for growing a plant and performing forest greening on sandy land and dry land such as sand dunes and deserts, and a sandy land greening method using the seedling pot.
[0002]
[Prior art]
Conventionally, when plants are introduced into sandy lands such as sand dunes and deserts with poor water retention, and dry land, a thick layer of land is used or water supply means such as a sprinkler has been adopted. However, these methods require a large amount of money, and in the desert in the dry zone, there is a problem that salt water damage occurs due to remarkable evaporation of the water supplied, and eventually the barren land becomes more severe.
[0003]
[Problems to be solved by the invention]
Therefore, the present invention provides a soil base having a submerged water layer at the bottom of the sand under certain soil conditions and weather conditions, such as sand dunes, deserts, and dry land, which are difficult to be planted, and which is reliably affected by the seedlings. The main purpose of the present invention is to provide a seedling pot that is steadily biodegraded and does not remain in the environment.
[0004]
[Means for Solving the Problems]
In order to achieve the above object, the present invention takes the following technical means. That is, the seedling pot according to the present invention includes a cylindrical outer layer 1 having a predetermined height formed of biodegradable non-wood fibers, a cylindrical intermediate layer 2 having water retention and water absorption , fertilizer A seedling pot is constituted by the inner layer 3 made of soil mixed with the above, the intermediate layer 2 is formed as a unit divided into a plurality of stages inside the outer layer 1, and the seedling pot is fitted to each other, The structure can be jointed vertically. By forming the intermediate layer 2 as a unit structure, it becomes easy to form, and by increasing or decreasing the number of intermediate layers as necessary, the outer layer 1 corresponding to the overall length is formed to form a seedling pot of any length Can be obtained.
[0005]
It is preferable that the upper end portion of the intermediate layer 2 of the seedling pot protrudes slightly above the upper end of the outer layer 1 and the lower end of the intermediate layer 2 is slightly inserted from the lower end of the outer layer 1. Thereby, a plurality of seedling pots can be used jointly up and down.
[0006]
Further, the present invention connects a plurality of the above seedling pots to a length that reaches the soil base having the underground water at the bottom of the sandy land such as dry land, dunes, deserts, etc. The seedlings are planted in the inner layer 3 and settled, and water is poured into the seedlings at a predetermined interval until the root reaches the soil base and settles on the soil base. In addition, the seedling pots used are surely promoted with a small amount of water, and the used seedling pot provides a method for greening sandy soil that does not remain in the environment.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, details of the present invention will be described with reference to the accompanying drawings.
1 to 3 show a typical embodiment of a seedling pot according to the present invention, which is a cylindrical outer layer 1 made of a biodegradable material, and a cylinder having water retention and water absorption. The intermediate | middle layer 2 and the inner layer 3 which consist of soil which mixed the fertilizer are comprised.
[0008]
The cylindrical outer layer 1 is formed by press-molding non-wood fibers such as bamboo, straw and palm (leather leather), preferably 10% bamboo and 60% straw are dissolved in 30% palm after boiling. The paper is made by compression molding into a round cylinder under a pressure of 3 kg / cm ² or more and a temperature of 210 ° C. In this example, the outer diameter is 10 cm, the height is 100 cm, the thickness is 5 mm, and the outer surface is coated with a biodegradable resin seal or spray, and the complete biodegradation in sand is about the coating portion. Consideration is made so that the inner non-wood fiber portion is about 300 days later after 700 days.
[0009]
The intermediate layer 2 is formed by kneading shells such as oysters, shells of crustaceans such as crabs, and 30% cocoons into 70% palm and compressing them into a cylindrical shape. As a result, it is possible to obtain an intermediate layer that retains excellent water retention and water absorption while maintaining its form with an appropriate hardness, and also has a soil disease inhibitory power and fertilizer effect possessed by an organic shell. In the present embodiment, one unit has an outer diameter of 9 cm, an inner diameter of 5 cm, and a height of 10 cm, and 10 units are inserted into the outer layer 1. At this time, the uppermost unit protrudes slightly from the upper end of the outer layer 1, for example, 4 cm above, and the lowermost unit is set to enter about 4 cm from the outer layer 1. Thus, a plurality of seedling pots can be used by jointing up and down as shown in FIG.
[0010]
The inner layer 3 is configured by mixing 0.2% or more of fertilizers such as nitrogen, phosphoric acid, potash and the like in the soil, and is packed in a cavity in the cylindrical inner layer 2.
[0011]
The upper surface and the lower surface of the intermediate layer 2 are covered and protected by a thin disc-shaped upper lid 4 and lower lid 5 made of the same material as the outer layer 1. Both the lids 4 and 5 are provided with a large number of small holes, and are formed so as to be easily excised by providing a break line in advance in a portion corresponding to the internal cavity of the intermediate layer 2. The upper lid 4 may be opened in advance as shown in the drawings.
[0012]
As shown in FIG. 4, the above seedling pots are connected to a length that reaches the soil base B having the underground water at the bottom of the sandy land A such as dry land, dunes, and deserts. Or a seedling is planted in the inner layer 3. After the seedling has settled, about 1 liter of water is poured once every 30 days until the root reaches the soil base B as shown in FIG. At this time, since the intermediate layer 2 is excellent in water retention and water absorption, the seedling roots can be effectively moistened with a small amount of water for a long time. In addition, the inside of the seedling pot is not affected by the environment in the sand until the outer layer 1 is coated and sealed, and the outer layer itself is decomposed. It is possible to reach the soil base B having If the roots of the seedlings reach the soil base B, the roots are settled and then cultivated by themselves. In this breeding process, the organic shells of shellfish and crustaceans contained in the intermediate layer 2 exhibit soil disinfection effects to suppress soil diseases and contribute to the growth of seedlings as organic fertilizers. Moreover, the used seedling pot does not remain in the environment by being biodegraded steadily after the passage of time.
[0013]
Although typical embodiments of the present invention have been described above, the present invention is not necessarily limited to the above-described embodiments. For example, the height of the outer layer 1 and the number of units of the intermediate layer 2 accommodated in the outer layer 1 can be arbitrarily changed. Further, the upper lid 4 and the lower lid 5 that cover the upper and lower surfaces of the intermediate layer of the seedling pot can be omitted. In addition, in the present invention, it is needless to say that the present invention can be implemented with appropriate modifications within the range having the structural requirements and the effects.
[0014]
【The invention's effect】
Since the present invention is configured as described above, it is under soil conditions and weather conditions such as sand dunes, deserts, and dry land that are difficult to be greened, and the roots of the seedlings are reliably placed in the sand without being affected by them. It is possible to reach the soil base having the bottom underground water layer to promote the establishment of seedlings. In particular, in the present invention, since the seedling pot can be jointed up and down, the total length of the seedling pot can be freely controlled according to the formation of the sand, and the depth of the sand to the soil base of the underground water layer can be controlled. There is no limit . Together with the molding is facilitated by the or intermediate layer and the unit structure, seedling pots any length by molding an outer layer was increased or decreased as necessary to the overall length of the number of intermediate layers Can be obtained. Furthermore, the used seedling pot has various effects such that it steadily biodegrades after a predetermined date and time and does not remain in the environment.
