Description
466 494 z jord skall transporteras vidare och sättas om i annan jord. 466 494 z soil must be transported further and transferred to other soil.
Det har nu befunnits att dessa olägenheter kan undanröjas eller väsentligen nedbringas, om man som odlingsmedium i det första steget använder en relativt liten formstabil pluggliknan- de kropp av odlingsmedium och att man, sedan fröet bildat en växt eller sticklingen bringats att växa i önskad grad, an- bringar den formstabila pluggliknande kroppen av odlings- medium i en urtagning i en större formstabil kropp av odlings- medium för den fortsatta tillväxten, varvid odlingsmedierna består av ett aggregat av partiklar med hög densitet, som upp- visar mikroporer i stånd att upptaga vatten och mellan sig dessutom uppvisar luftgenomsläppande makroporer. Härvid är partiklarna företrädesvis erhållna genom hoppressning av hydro- fila organiska fibrer till den höga densiteten.It has now been found that these inconveniences can be eliminated or substantially reduced if a relatively small dimensionally stable plug-like body of culture medium is used as the culture medium in the first stage and that, after the seed has formed a plant or the cutting is made to grow to the desired degree, places the dimensionally stable plug-like body of culture medium in a recess in a larger dimensionally stable body of culture medium for continued growth, the culture media consisting of an aggregate of high density particles which exhibit micropores capable of absorbing water. and between them also exhibit air-permeable macropores. In this case, the particles are preferably obtained by compressing hydrophilic organic fibers to the high density.
Uppfinningen skall i det följande beskrivas närmare under hänvisning till bifogade ritning, där '" Fig. 1 visar en pluggliknande formkropp av ett odlings- medium för att bringa ett frö att gro, Fig. 2 en skiva av samma odlingsmedium som i fig. 1 med en urtagning för insättning av den i fig. 1 visade pluggen och Fig. 3 skivan i fig. 2 med insatt plugg enligt fig. 1.The invention will be described in more detail below with reference to the accompanying drawing, in which "Fig. 1 shows a plug-like shaped body of a culture medium for causing a seed to germinate, Fig. 2 a disc of the same culture medium as in Fig. 1 with a recess for inserting the plug shown in Fig. 1 and Fig. 3 the disc in Fig. 2 with inserted plug according to Fig. 1.
Under hänvisning till ritningen visas i fig. 1 en plugg- liknande formstabil kropp 1 av ett odlingsmedium bestående av ett aggregat av genom pressning av cellulosafibrer erhåll- -- na partiklar, varvid partiklarna uppvisar mikroporer i stånd att uppta vatten under inverkan av kapillärkrafter och makro- porer mellan partiklarna, som bildar en struktur av genom- gående och luftgenomsläppande kanaler. I den pluggliknande kroppen 1 införes till att börja med ett frö 2 av t.ex. en skogsplanta och det hela införes i ett växthus med kontrolle- rade temperatur- och luftfuktighetsbetingelser. Efter lämplig tillförsel av näring och vatten bringas fröet att gro. Even- tuella kroppar med frön, som icke gror, avlägsnas från växt- huset. Så snart man kan antaga att den vid groningen bildade växtens ytterligare tillväxt stabiliserats och växten blivit tillräckligt härdig för att tåla mindre kvalificerade beting- elser utomhus, insättes den pluggliknande kroppen 1 med planta i en i fig. 2 visad större odlingskropp 3, som har en för ända- 3 466 494 målet avpassad urtagning 4, så att den sammansatta kroppen får det i fig. 3 visade utseendet. Den senare kan sedan an- bringas i en säng och utrymmet omkring kroppens periferi fyllas upp med jord. Den sammansatta kroppen får sedan stanna i sängen tills plantan vuxit ut så långt att växten lämpar sig för plantering på sin slutliga plats. Företrädesvis anbringas emellertid den sammansatta kroppen på ett markunderlag med luftspalt mellan det senare och kroppens undersida. I detta fall kan den större odlingskroppen 3 vara omgiven av ett fukt icke genomsläppande hölje av termoplast eller annat lämpligt material. Genom att både den pluggliknande odlingskroppen 1 och den större odlingskroppen 3 är formstabila, underlättas i hög grad den mekaniska hanteringen av kropparna i samband med omskolningsoperationen.Referring to the drawing, Fig. 1 shows a plug-like dimensionally stable body 1 of a culture medium consisting of an aggregate of particles obtained by pressing cellulose fibers, the particles having micropores capable of absorbing water under the influence of capillary forces and macro - pores between the particles, which form a structure of continuous and air-permeable channels. In the plug-like body 1 is initially introduced with a seed 2 of e.g. a forest plant and the whole is introduced into a greenhouse with controlled temperature and humidity conditions. After a suitable supply of nutrients and water, the seed is brought to germinate. Any bodies with seeds that do not germinate are removed from the greenhouse. As soon as it can be assumed that the further growth of the plant formed at germination has stabilized and the plant has become sufficiently hardy to withstand less qualified outdoor conditions, the plug-like body 1 with plant is inserted into a larger culture body 3 shown in Fig. 2, which has a recess 4 adapted for the purpose, so that the composite body has the appearance shown in Fig. 3. The latter can then be placed in a bed and the space around the body's periphery filled up with soil. The composite body is then allowed to remain in the bed until the plant has grown so far that the plant is suitable for planting in its final place. Preferably, however, the composite body is applied to a ground substrate with an air gap between the latter and the underside of the body. In this case, the larger culture body 3 may be surrounded by a moisture-impermeable casing of thermoplastic or other suitable material. Because both the plug-like culture body 1 and the larger culture body 3 are dimensionally stable, the mechanical handling of the bodies in connection with the retraining operation is greatly facilitated.
Odlingsmediet i de formstabila kropparna 1 och 3 består av komprimerade aggregat av cellulosafibrer från barrträd.The culture medium in the dimensionally stable bodies 1 and 3 consists of compressed aggregates of cellulose fibers from conifers.
Härvid har dimensionerna på aggregatet avpassats så, att det av denna sammansatta odlingsmediet får en viss porositet med porer, vilkas medelporstorlek ligger mellan 30 och 300 p. Cellulosa- fibrerna har en sådan täthet, att medelporstorleken hos de inre porerna kommer att ligga vid ca 10-30 p. Genom kraftig hop- pressning och materialets egenskaper blir förmågan att upptaga vatten begränsad, så att odlingsmediet även vid kraftig vatt- ning behåller sin struktur samtidigt som tillräckligt med vat- ten kvarhålles i de mindre porerna utan att luftens tillträde till rötterna hindras i icke önskad grad. De större porerna har väsentligen icke kapillära dimensioner och bildar sålunda ett lämpligt dräneringssystem, som möjliggör god omsättning av vatten i det för rötternas utveckling använda substratet.In this case, the dimensions of the assembly have been adjusted so that the culture medium of this composite has a certain porosity with pores, the average pore size of which is between 30 and 300 .mu.m. -30 p. Due to strong compression and the properties of the material, the ability to absorb water is limited, so that the culture medium retains its structure even during heavy watering while retaining sufficient water in the smaller pores without hindering the access of air to the roots. to an undesirable degree. The larger pores have essentially non-capillary dimensions and thus form a suitable drainage system, which enables good circulation of water in the substrate used for the development of the roots.
Väsentligt för uppfinningen är kombinationen av långvarig vatten- upptagande förmåga genom den täta delens kapillära och kolloi- dala system med möjligheten att omsätta vatten, genom systemet med större porer, samtidigt som odlingskroppen är väsentligen formstabil.Essential to the invention is the combination of long-term water-absorbing ability through the dense capillary and colloidal systems of the dense part with the possibility of converting water, through the system with larger pores, while the culture body is substantially dimensionally stable.
