Definitions

• the invention concerns a plant growing frame, in which a certain num ⁇ ber of mutually seperated small plants can be held tight, cultivated, and h ndled.
• Frames or lean-toes in which a certain number of small plants can be held tight, cultivated arid handled are known.
• every root system of the " plants are sideways surrounded with a wall, which hinders root graft.
• These walls constitute a container around the root system of every plant and these containers can be mutually joined together to a fra- me or be placed in a lean-to, so a suitable number og plants can be handled in one flow of work, either by hand or maschine.
• Each con ⁇ tainer can be filled with a suitable, comminuted growing medium, for instance, sphagnum, sand, granulated stonecrop or mixtures of these sorts.
• the container wall which surrounds each root system of the plants, has a forming effect on the roots of the plants because their growth are forced to follow the walls and maybe the bottom.
• This form ⁇ ing effect has an unwanted effect on the root system of the plants and is called root deformation.
• the root .deformations grow with in ⁇ creasing growing time in a container of a certain size. Root defor- mations are especially known in the production of container plants for use in foresty, these plants have bad wind firmness, hampered root growth or even bring root strangulation along.
• the plant growing frame is peculiar be ⁇ cause each growing medium of the plants is held tight in a way so they are mutually seperated by an air space.
• a decisive condition of the air-pruning effectively will hinder root graft from one growing medium block to another is that the air spa ⁇ ces are made in a way so the air can move freely under the bottom of the plant frame vertically up between the growing medium blocks on all sides and allow air to pass between the growing medium blocks.
• the comparative moisture " of the atmosphere between the growing medium blocks will be so high that root graft will take place between the growing medium blocks themselves. This will decisively reduce the vitality of the plants, when they are seperated and transplanted, because the plants by separation will loose a lot of their root system, exactly the part which is grown out into the surrounding growing medium blocks.
• the plant growing frames known from British patent specification no. 1.426.313 are identical with those plant growing frames known from American patent specification no. 3.938.281, which all are charac ⁇ terized by that in the bottom the plant growing frames absolutely stop the vertical air movement between the growing medium blocks, because these plant growing frames are closed in the bottom between the growing medium blocks.
• the systems have also been given up be- cause of the widespread root graft between the growing medium blocks.
• the plant growing frame known from Ame ⁇ rican patent specification no. 3.971.160 is different from this one because it does not use air-pruning at all.
• the transparent bag, which surrounds the plant growing frames will result in a high co - parative moisture of the atmosphere so air-pruning would not take place. That is why the plant growing frame, according to the patent specification is made with vertical walls in the bottom between the growing medium blocks, so these walls hinder root graft. This plant growing frame is also closed in the bottom between the growing me ⁇ dium blocks.
• the plant growing frame is decisively different, - aoc ⁇ ording to the patent specification from this plant growing frame, which according to the invention is made in a way so it with air-pruning alone, achieved with an absolutely free air movement between the growing medium blocks effectively hinders root graft between the growing medium blocks themselves.
• transplanted plant with all its root system quickly establish itself on the permanent habitat with a quite natural root form witout root deformations.
• a typical use of the plant growing frame according to the invention will be by production of trees for transplanting in woods.
• the plant growing frame will for a typical two-year nursery period hold tight the growing medium blocks so they in all stages from direct seeding, growing, sorting and clearing up for delivering in the woods, they are mutually seperated of the air space, which will secure the wan ⁇ ted air-pruning of the root systems.
• the plant growing frame out of consideration for ' an effective handling will in normally follow the plants out in the wood to the habitat, where the plant with the growing medium block will be emancipated from the plant growing fra- me and transplanted, and out of the growing medium blocks and out in to the earth.
• the plant growing frame of the mentioned kind is characterized by that the growing medium frames are held tight by certain organs in the plant growing frame, so the blocks sideways are mutually seperated of an air space, which run from under the bottom of the growing medium blocks and continue vertically up between the blocks on all sides and up above these.
• the ' air space must have a width that the comparative moisture of the atmosphere of the air space by the free air movement, under certain growing conditions can be held so low, that the air-pruning of the root systems is effec- 5 tive.
• the organs which secure the growing medium blocks only touch a small part of the sides of the growing medium blocks, bottom and surface, so their small extent not brings any root deformations along.
• the securing organs in the growing frames are able to secure the o growing medium block so securely that, irrespective of whatever in- flunces the growing frame in connection with common handling. Though it has to be possible with a steady pull with the hand to emancipate the growing medium blocks seperately in the connection with trans ⁇ plantation, sorting or transplanting.
• a particular easy plant growing frame to made is, according to the available invention, characterized by the organs which secure the growing medium blocks are made out of consecutive- ribs or bands
• fig. 1 shows the plant growing frame in perspective
• fig. 2 shows a vertical section along the line 11-11 in fig. 1
• fig. 3 shows the plant growing frame in perspective in another em- o bodiment.
• the available invention can be made in a lot of different embodiments of which the chosen possibilities as mentioned are shown on the draw ⁇ ing.
• the figures on the drawing are parts with the same function de ⁇ scribed with the same reference description, eventhough the embodi- 5 ments can be different.
• the invention concerns only these subjects which are described with numbers, while the subjects, which are scribed with letters are already known and only mentioned here to un ⁇ derstand the drawing better.
• the plant growing frame consists of a frame 1, ih' hich a network 2 is streched out.
• the network 2 On fig. 1 and fig. 2 the network 2 is made as double 5 ribs, whose vertical extent only is a fraction of frame 1.
• the ribs or the network 2 is held tight to the frame 1 on the level near the vertical centre of the frame.
• the ribs/network 2 on fig. 1 and fig.2 is devided so seen from above that some links are made, which in size and shape fit the form stable growing medium blocks A, lo which are chosen for the purpose, so the growing medium blocks A can be secured.
• the ribs/network 2 can be made with one or several knots 4 per link 3.
• the double ribs in the network serve the purpose, that between the suitable links for the growing medium blocks 4, there is links with another dimensi- 5 on which secure that there between the growing medium blocks is an air space 5 of such a size (width) that air-pruning of the root system C of the plants B will be effective.
• the plant growing frames on all three figures are just partly filled with growing medium blocks A, and a number of these o are filled with plants B and on fig. 2 shown with a root system C.
• FIG. 3 On fig. 3 another ambodiment is shown when the network 2 form the bottom in the frame 1.
• the net ⁇ work/bottom 2 is made with some vertically standing nails or sticks 6.
• the nails or sticks 6, of which there has to be at least one per 5 growing medium block can be made with a form or roughness, which makes the nail able to secure the growing medium blocks A effectively, after the blocks A have been placed over the nails 6.
• plant growing frame is shown with room for 48 growing medium blocks A and in fig. 3 for 4o blocks.
• the number of growing medium blocks are abitrarily chosen.
• the growing medium frames will be made to a certain culture with a number of growing medium blocks A, which one will find suitable for purposes of growing and handling.
• the plant growing frames can be made with certain organs, which must show itself suitable for hand ⁇ ling by hand or maschine, for instance, handles, holes, knots etc. in the plant growing frame.
• Such handling organs are not shown on the drawing because the embodiments can be several.
