HU195067B - Method and vessel and vessel set for raising ligneous plants particularly saplings - Google Patents

Abstract

The invention specifies a method, in particular for cultivating seedlings in pots provided with root-outlet openings, in which the pots are arranged in a vertical or approximately vertical position, while forming an air gap, corresponding to at least 5% of the pot length, from the soil or any other plane. For this purpose, the pots exhibit vertical ribs on the inner casing surface and a root-outlet opening in the region of the base.

Description

The present invention relates to a method for growing woody plants, in particular saplings.

The invention also relates to a vessel suitable for carrying out the process as well as to the construction of a series of vessels.

It is known that seedlings are used for growing and propagating woody plants, especially saplings, where the root system is protected by a ball. This results in a slower growth of the seedling root system into the soil. On the one hand, this can lead to a loss of growth and, ultimately, to the death of the seedling.

Another development is the paper cell solution, where the application can be applied in areas with high soil moisture. Another technical solution is to provide vessels with ribs on the inner peripheral surface and a root outlet opening at the bottom. This ensures the so-called air pruning or killing, which results in a significantly higher rate of emergence of the seedlings thus grown after planting. However, this solution has the disadvantage that individual pots or containers placed either close to the ground or in the ground do not always ensure the likelihood of killing by air since the space between the pots and the ground is not always provides a periodic cessation of growth. The arrangement of the propagation or breeding pots of this design in the sand further deteriorates the result.

Also known is the so-called foil hose design, which has the disadvantage of growing large amounts of seedlings. These are mainly the difficulty of moving and planting material and the long, many years of rearing. On smooth foliage, the root system of the seedling tends to grow round, with deleterious consequences in the years after planting. A similar root developmental disorder appears at the bottom of the pots if the root system cannot grow into the seedling soil. However, in the case of overgrowth, the adult root system must be cut off at the time of emergence, so that seedling growth will not be uniform after planting.

To avoid this, a solution has been found in which the root system of seedlings planted in a pot collides with the pot wall during growth and develops circumferentially along the wall. When the surrounding root strikes the ribs on the wall, it changes direction and develops further toward the bottom of the vessel.

The pots are positioned during the rearing season so that there is an air gap underneath them. As soon as one end of the seedlings developing in the pot reaches the bottom of the pot, it grows into this air gap and, in the absence of living conditions, is destroyed. As a result, a new root initiation 2 develops in the upper part of the root system. This process - the continuous aerial incision of the root system - continues throughout the growing cycle, resulting in the formation of a very rich multi-ended root system.

However, this design has the disadvantage that the root ball-protected part of the root system is slower to grow into the soil. On the one hand, this can lead to a loss of growth and, ultimately, to the death of the seedling.

It is an object of the present invention to provide a method and a series of pots, in particular for growing and propagating saplings, which do not have the disadvantages described above and which, by their application, can carry out the above process with great efficiency.

The present invention is based on the discovery that surprisingly efficient growth is achieved by placing pots prepared for propagation and having a rib and a root outlet in an upright or close position, leaving at least 5% of the airspace from the ground or other plane.

It is expedient to arrange a series of propagation pots, not only in length but also in width, in a plate-like manner.

Further, depending on the expected type of root system to be formed, said ribbed material is formed in a widening or narrowing form from the ground down. The latter realization is based on the fact that different root forms of different shapes are formed in different ways within a given container.

Thus, the present invention provides a method for growing woody plants, in particular saplings, in a container (s) having root outlets, the container being positioned in an upright or proximal position leaving at least 5% of the air gap from the ground or other plane.

The vessel suitable for carrying out the process is characterized in that the inner peripheral surface of the vessels has vertical ribs and a root outlet opening around the bottom.

Preferably, the ribs on the peripheral surface are structurally widening along the length of the vessel and tapering downward on the inner peripheral surface. When at least two of the vessels are fixed to one another in a common lower plane, they form a series of vessels according to the invention.

The propagation vessel preferably has a circular or rectangular opening at the bottom of the plastic container. The purpose of this opening (root opening) is twofold:

- removal of excess water

- Breathing.

-2195067

If the plastic containers are placed directly on the ground during cultivation, the developing roots penetrate into the soil at the root outlet and must be cut or trimmed when the seedling is removed. When placed on a solid medium (concrete, brick, eternite slab, etc.), the outgoing roots begin to develop in a horizontal direction and, when removed, these excess roots must be cut into juice. (Can not be planted, dehydrates during transport.) Damaged root is prone to infection and causes developmental shock.

The air is cut as follows: the containers are not on the ground, but on the underlay, so that the root outlet is in the air (min. 50 mm from the ground, but varies with container size). The developing root stepping out of the opening completes its growth as it is released into the air (unharmed) and thus causes the seed to develop a new root. This continuous air cutting ensures that the earth cone in the container is completely permeated by roots.

The size of the root outlet affects the growth time, as the roots may block the outlet, which is no longer allowed.

The new roots of the seedlings planted will develop primarily from the aerated roots at the outlet. For better root formation, multiple lateral root outlets should be provided at the lower conical end of the container to exclude root compaction. For these side exits, the traditional ribs need to be reshaped - from top to bottom, so that the roots can be redirected to the new aperture.

The technical solution according to the invention is described in detail in the accompanying drawings, where

Fig. 1 is a longitudinal sectional view of an embodiment of the container of the invention, a

Figure 2 is a plan view of the same vessel, a

3 and 4 are a longitudinal section and a top view of another embodiment.

The container of Fig. 1 is made of plastic, the wall 3 is slightly tapered downwards and then tapered in its lower one-sixth so that only the root outlet 2 remains. The vertical l / a ribs are formed on the wall 3. The first container of Figure 1 shows the tapering ribs 1.

The pot solves the object of the present invention as follows: The root of the seedlings propelled in the pot hits the pot wall during growth and develops in a circular fashion along the wall. When the surrounding root strikes the ribs on the wall, it changes direction and develops further toward the bottom of the vessel.

The pots are positioned during the rearing season so that there is an air gap underneath them. As soon as one end of the seedlings developing in the pot reaches the bottom of the pot, it grows into this air gap and, in the absence of living conditions, is destroyed. As a result, a new root initiation develops in the upper part of the root system. This process - the root system is continuous. aerial incision - continues throughout the growing cycle, resulting in the formation of a very rich, multi-ended root system. Such root system penetrates into the soil 1-2 weeks after planting and ensures continuous growth of the seedling.

Because the wall of the pot is tapered, the seedlings can be easily removed without damaging the roots.

It can be clearly seen from Figures 1 and 2 that these vessels can be fixed to each other. Optionally, the vessels are secured to one another by ribs 4 and 5 parallel to their longitudinal axis. As a result of reattachment, rows of multiple pots and blocks of multiple rows can be formed.

Figures 3 and 4 also show containers fixed to each other, arranged in series. In addition to the ribs 4, the containers are secured to one another by an upper cover plane 6. Of course, in this way blocks from such vessels can also be formed.

Both fastening methods are suitable for making large quantities of vessels using mass production technology.

Preferably, the containers are made of a stabilized plastic material which is resistant to various weather conditions or changes. Of course, it can be made of metal, wood or any other material from which the shape described can be formed with a properly smooth wall.

Otherwise, a cylindrical or column-shaped vessel is suitable for root cultivation. The tapered design makes it easier to highlight the seedling.
