2. Description of the Related Art Demand for timber, which is indispensable to human life as a building material or a raw material for papermaking, has rapidly increased due to the development of social culture and technological innovation, which has led to large-scale deforestation. ing. For this reason, from the viewpoint of securing limited natural resources and environmental protection, planting forests on the site of felled trees occupies an important field as one of the key industries. Further, from the viewpoint of recent global environmental protection, various greening projects have been proposed to actively green the vast undeveloped area. By the way, in the conventional tree planting method, first, seeds are sown on a nursery, raised for a required period of time, and the grown saplings are dug up and transported to a planned tree planting site in the forest, and then manually digging the predetermined planting holes. And planting seedlings one by one. And in normal forests, the daily work load is 2
The standard is to plant about 2,000 seedlings, weighing about 20 kg. For this reason, planting work is extremely hard work and requires a lot of manpower, so under the current situation of chronic labor shortage in the agriculture and forestry industry, it is becoming extremely difficult to plant trees in the logging site, let alone in undeveloped areas where planting is not possible. The current situation is that it is almost impossible to plant trees and deserts.

[0003]

In view of the above situation, the present invention was devised by a completely new concept in order to eliminate the problems in the conventional tree planting method, and its purpose is to Also, even in the case of logging sites or vast undeveloped areas where it is impossible to settle, seedling pots carried by air vehicles can be simply dropped in the air, and it is easy to plant trees without the need for additional manpower. Trying to serve the pot.

[0004]

In order to solve the above-mentioned problems, the technical means adopted by the present invention is a conical cylinder or a polygonal conical cylinder in which liners are made of cardboard and arranged in parallel in the height direction of the outer wall. The seedling pot main body of No. 1 is formed so that it can be freely assembled and disassembled, and lathed paper is used as the material on the inner peripheral surface of the seedling pot main body.
It is common to add a water retaining body made of water-absorbent polymer and a fertilizer body made of organic fertilizer, enzymes, etc. to the honeycomb-shaped space formed by expanding the lath.
On the upper edge side of the outer peripheral surface of the seedling pot body, a predetermined interval
The punched groove in the shape of the feather body.
It is characterized in that the spiral blade body is automatically formed so as to protrude when the pot body is assembled .

[0005]

According to the present invention, therefore, the seedling pot body formed in the shape of a conical tube or a polygonal pyramid is made of cardboard as a material that can be assembled and disassembled, but the liner is arranged in the height direction of the outer wall. As they are arranged side by side, they exert strong strength in the vertical direction. Then, seedlings, cuttings, etc. are planted in a seedling pot to which a belt-shaped fertilizer body is attached, and then the seedling pot is transported to the desired planting location by a radio-controlled helicopter, etc. , and the seedling pot is dropped into the air as it is, so that the seedling pot has its outer periphery Due to the air resistance of the spiral blades projecting on the surface, the cone-shaped cusp is submerged in the soil while reliably turning and vertically descending. And the roots of the seedlings in the seedling pot are sucked inside the strip.
It absorbs water from the water holding body consisting of an aqueous polymer or the like, organic
Fertilizer is supplied from a fertilizer body made of fertilizer, enzymes, etc.
Moreover, since the seedling pot body has air permeability and heat and cold resistance, it smoothly extends along the inner surface of the seedling pot and sticks to the ground. In addition, the seedling pot itself, which is made of cardboard, decomposes over time and becomes organic fertilizer to promote the growth of seedlings. Therefore, it is possible to contribute to the greening of the vast undeveloped area, which was conventionally impossible to settle.
