Abstract

A cell block consisting of parallel rows of vessels for the cultivation of plants, wherein a non-decaying centre layer 6 is set in the vessel wall 5. On the sides of the vessel there is an outer layer 7 which decays during cultivation, while in the joints between the rows of vessels there is a non-decaying wing 8 to prevent rotation of the root system. <IMAGE>

Description

15 20 25 30 35 462 699 Nu har ett uppdragningscellblock uppfunnits, i vilket kärlväggen har ett icke förmultnande centerskikt på vars båda sidor finns ett under uppdragningen förmultnande ytskikt, var jämte i skiljeväggarnas skarv- ställen finns ett mot kärlet pekande, under uppdragningen icke för- multnande, vertikalt längsgående utsprång. 15 20 25 30 35 462 699 Now a drawing cell block has been invented, in which the vessel wall has a non-decaying center layer on both sides of which there is a decaying surface layer, where in addition to the splice points of the partitions there is a pointing towards the vessel, during drawing decaying, vertically longitudinal protrusions.

En gynnsam utföringsform av uppfinningen beskrivs närmare med hjälp av de vidliggande ritningarna.A favorable embodiment of the invention is described in more detail with the aid of the accompanying drawings.

Fig 1. visar en perspektivbild av hela cellblocket, och Fig. 2 visar skarvstället mellan två bredvid varandra liggande kärl uppifrån sett.Fig. 1 shows a perspective view of the entire cell block, and Fig. 2 shows the joint between two adjacent vessels seen from above.

Cellblocket 1 består av kärl 2 med sexkantform. Cellblocket 1 fram- ställs på ett i och för sig känt sätt genom att man limmar ihop lami- nerade ark av önskat slag på lämpliga ställen 3. Vid öppning skiljer sig arken från varandra i de olimmade partierna och bildar därmed cellblocket.Cell block 1 consists of vessel 2 with a hexagonal shape. The cell block 1 is produced in a manner known per se by gluing together laminated sheets of the desired type in suitable places 3. When opened, the sheets differ from each other in the non-glued parts and thus form the cell block.

Vid cellblockets 1 skarvställen 3 har anslutits in i kärlet utstående vingar 8.At the joint points 3 of the cell block 1, protruding wings 8 have been connected into the vessel.

Cellblookets 1 väggar 5 har gjorts av laminat med tre skikt. Som mel- lersta skikt 6 ligger i lamínatet ett icke förmultnande material, t ex lämplig plast såsom polyeten eller polypropen. På ömse sidor av cen- terskiktet 6 ligger ett tunt, under uppdragningens lopp förmultnande ytskikt 7, som bäst består av papper. Centerskiktets 6 tjocklek (yt- vikt) är 10 - 50 g/m2, lämpligast 20 - 30 g/m2, och ytskiktets 7 tjocklek (ytvikt) 15 - 70 g/m2, lämpligast 20 - 25 g/m2.The walls 5 of the cell block 1 have been made of laminate with three layers. As the middle layer 6, a non-decaying material is present in the laminate, for example suitable plastic such as polyethylene or polypropylene. On either side of the center layer 6 is a thin surface layer 7, which decays during the drawing process, which best consists of paper. The thickness of the center layer 6 (basis weight) is 10 - 50 g / m2, most preferably 20 - 30 g / m2, and the thickness of the surface layer 7 (basis weight) 15 - 70 g / m2, most preferably 20 - 25 g / m2.

I kärlväggarnas 5 skarvställe 3 ligger mellan kärlväggarna en med dem parallell vinge 8, som stäcker sig ur ett kärl 2 in i ett annat. Ving- en 8 har framställts av oförmultnande eller nästan oförmultnande mate- rial, såsom lämplig plast eller impregnerat papper. Vingen 8 bör ha lO 15 20 25 30 35 4-62 6969 tillräcklig styvhet så att den bibehåller sin form när kärlen 2 fylls med växtsubstrat.In the joint 3 of the vessel walls 5, between the vessel walls there is a wing 8 parallel to them, which extends from one vessel 2 into another. The wing 8 is made of non-rotten or almost non-rotten material, such as suitable plastic or impregnated paper. The wing 8 should have sufficient rigidity so that it retains its shape when the vessel 2 is filled with plant substrate.

Skarvstället 3 har bildats genom fastlimning med oförmultnande och i vatten olösligt lim av de vertikala fogarna 9 och 9' vid skarvställets mot kärlen liggande kanter. Limningen har utförts så att fogarna st- räcker sig från ett oenterskikt 6 till det andra, men på så sätt att limmet inte fastnar vid själva centerskiktet.The splice stand 3 has been formed by gluing with non-decaying and water-insoluble glue of the vertical joints 9 and 9 'at the edges of the splice stand against the vessels. The gluing has been carried out so that the joints extend from one lower layer 6 to the other, but in such a way that the glue does not stick to the center layer itself.

Ytskikten förmultnar under uppdragningen, varefter plantklumparna kan skiljas från varandra i och med att man avlägsnar de mellan plantorna kvarstående centerskikten 6 och vingarna 8.The surface layers rot during the application, after which the plant clumps can be separated from each other by removing the center layers 6 remaining between the plants and the wings 8.

Centerskiktet 6 samt limfogarna 9 och 9' förhindrar att rotsystemet växer ur en klump in i en annan under uppdragningen, och vingen 8 förhindrar att rotsystemet fortsätter rotera utmed kärlets 2 vägg.The center layer 6 and the glue joints 9 and 9 'prevent the root system from growing from one lump into another during the pull-up, and the wing 8 prevents the root system from continuing to rotate along the wall of the vessel 2.

Om så behövs, kan rotsystemets tillväxt regleras med hjälp av till- växtinhiberande ämnen i kärlväggarnas ytskikt 7 eller i deras skarv- ställen 3. I skarvställena 3 kan man i limfogarna 9 och 9' eller mel- lan dessa utan men också bruka riklig dosering.If necessary, the growth of the root system can be regulated by means of growth inhibiting substances in the surface layers 7 of the vessel walls or in their joint places 3. In the joint places 3 the adhesive joints 9 and 9 'or between them can be used without but also abundant dosing.

I utförandet enligt figurerna kan man limma släta parallella pappers- banor, och limmens utbredning medför på sin höjd en minimal dimen- sionsspridning i krukans storlek.In the embodiment according to the figures, smooth parallel paper webs can be glued, and the spread of the glue at most results in a minimal dimensional spread in the size of the pot.
