Description

DK 153196BDK 153196B

5 Denne opfindelse angår en fremgangsmåde til dyrkning af planter, især skowækster.This invention relates to a process for growing plants, especially forest crops.

1 forbindelse med dyrkning af planter, enten det drejer sig om udendørs planter i planteskoler eller om 10 planter i drivhuse, er det altid ønskeligt at få dannet et så rigt forgrenet rodsystem som muligt, det vil sige så mange aktive rodspidser som muligt. Dette er en betingelse for, at planterne hurtigt kan udvikle sig og komme i kraftig vækst efter udplantning på 15 det nye voksested.In connection with growing plants, whether they are outdoor plants in nurseries or about 10 plants in greenhouses, it is always desirable to have as richly branched root system as possible, ie as many active root tips as possible. This is a prerequisite for the plants to develop rapidly and grow vigorously after planting at the new growth site.

En fremgangsmåde til tilvejebringelse af et rigt forgrenet rodsystem består i beskæring af rødderne.One method of providing a richly branched root system is to prune the roots.

Herved sker der naturligvis umiddelbart en svækkelse 20 af planten, men på længere sigt opnås et mere veludviklet rodnet, og dermed en mere veludviklet plante.This naturally leads to a weakening of the plant immediately, but in the longer term a more well-developed root network is obtained, and thus a more well-developed plant.

Der sker nemlig det, at en rod, når den får sin spids skåret væk, meget hurtigt danner en mangfoldighed af nye rodspidser, som i langt højere grad er i stand 25 til at optage vand og næring, end det var tilfældet med den oprindelige rodspids. Men grundet forskellige praktiske problemer har rodbeskæring hidtil kun været anvendt i begrænset omfang, hovedsageligt til forsøg.Indeed, when a root is cut away, a root very quickly forms a diversity of new root tips, which are much more capable of absorbing water and nourishment than was the case with the original root tip. . However, due to various practical problems, root pruning has so far only been used to a limited extent, mainly for experiments.

30 Fra tysk patentskrift 545.641 kendes et redskab til rodbeskæring af små planter på voksestedet. Redskabet består af en på et skaft monteret glidesko, på hvilken der er anbragt et i dybden justerbart skæreorgan, der, når giideskoen bevæges hen over jordoverfladen,30 German Patent 545,641 discloses a tool for root pruning of small plants at the growing site. The implement consists of a sliding shoe mounted on a shaft, on which is arranged a depth-adjustable cutting member which, as the guide shoe moves over the ground surface,

DK 153196 BDK 153196 B

2 kan bringes til at overskære planterødder i en forud indstillet dybde. Det er formentligt ret vanskeligt at arbejde præcist med det nævnte redskab, og det kan ikke bruges til rodbeskæring af planter, der vokser i 5 kompakt anbragte plantebriketter eller lignende, formede legemer af dyrkningsmedium.2 can be cut to plant roots at a preset depth. It is probably quite difficult to work precisely with the said tool, and it cannot be used for root pruning of plants growing in 5 compact plant briquettes or similar shaped bodies of culture medium.

Det er nærværende opfindelses formål, at tilvejebringe en fremgangsmåde til dyrkning af planter, især 10 skovvækster, som resulterer i billige planter af fineste kvalitet med øget grokraft.It is an object of the present invention to provide a method for growing plants, especially 10 forest growths, which results in cheap, finest quality plants with increased growth power.

Ifølge opfindelsen er der tilvejebragt en fremgangsmåde til dyrkning af planter, især skovvækster, i et 15 egnet vækstmedium, f.eks. en planteskive eller en anden velegnet form, som anbringes på et underlag, f.eks. grus, under hele kulturen, og det karakteristiske ved denne fremgangsmåde er, at planternes rodsystem jævnligt beskæres ved overskæring af rødderne, 20 hovedsagelig i et plan mellem dyrkningsmediet og dyrkningsunderlaget.According to the invention there is provided a method for growing plants, especially forest growths, in a suitable growth medium, e.g. a plant disk or other suitable form which is applied to a substrate, e.g. gravel, throughout the culture, and the characteristic of this approach is that the root system of the plants is regularly pruned by cutting the roots, 20 mainly in a plane between the culture medium and the culture medium.

Opfindelsen forklares nærmere under henvisning til tegningen, hvor 25 fig. 1 er et tværsnit af et dyrkningsunderlag med en derpå anbragt plante, der illustrerer grundprincippet i forbindelse med dyrkningen ifølge opfindelsen, 30 fig. 2 ligner fig. 1, men illustrerer en plante i en anden dyrkningsenhed og viser således en fremgangsmåde, som er noget mere udviklet i forhold til den i fig. 1 viste,The invention is further explained with reference to the drawing, in which: FIG. 1 is a cross-sectional view of a cultivation substrate with a plant placed thereon illustrating the basic principle of cultivation according to the invention; FIG. 2 is similar to FIG. 1, but illustrates a plant in another cultivation unit and thus shows a method which is somewhat more developed than that of FIG. 1,

3 fig. 3 er et tværsnit af et drivhus, i hvilket ses det ifølge opfindelsen anvendte dyrk-5 ningsprincip, fig. 4 er en perspektivtegning af nogle dyrkningsbeholdere , 10 fig. 5 er et lodret tværsnit af en dyrkningsbe holder umiddelbart efter udsåningen, og fig. 6 er et lodret tværsnit af en dyrkningsbeholder umiddelbart efter kimplantens frem-15 komst.3 FIG. Fig. 3 is a cross-section of a greenhouse in which the cultivation principle used according to the invention is shown; 4 is a perspective view of some cultivation containers; FIG. 5 is a vertical cross-section of a culture vessel immediately after sowing; and FIG. 6 is a vertical cross-section of a culture vessel immediately after the appearance of the seedling.

Fig. 1 er et skematisk billede af et underlag 10 bestående af et luftigt materiale såsom grus, sand 20 eller lignende. Oven på underlaget 10 er der lagt et net 11, der kan være af plast, med passende maskestørrelse. I det viste eksempel består nettet 11 af net længderne 11Ά og 11B, som anbringes på en sådan måde, at de overlapper hinanden; hvis der er flere 25 netlængder eller stykker, må overlapningen finde sted i én og samme retning af årsager, som vil blive beskrevet detaljeret i det efterfølgende.FIG. 1 is a schematic view of a substrate 10 consisting of an airy material such as gravel, sand 20 or the like. On top of the substrate 10 is a mesh 11, which may be of plastic, of suitable mesh size. In the example shown, the mesh 11 consists of the mesh lengths 11Ά and 11B which are arranged in such a way that they overlap; if there are more than 25 mesh lengths or pieces, the overlap must take place in the same direction for reasons, which will be described in detail below.

I eksemplet i fig. 1 dyrkes planterne 12 anbragt på 30 nettene 11, og i fig. 1 påtænkes dyrkningen at finde sted i en såkaldt planteskive 13, det vil sige et formet legeme bestående af et egnet dyrkningsmiddel, beklædt med et fugttæt lag, helst fuldstændig vandtæt, som er åbent nedadtil. Planternes rødder vil \In the example of FIG. 1, the plants 12 are grown on the nets 11 and in FIG. 1, the cultivation is contemplated to take place in a so-called plant disc 13, that is, a shaped body consisting of a suitable culture medium, coated with a moisture-proof layer, preferably completely waterproof, which is open downwards. The roots of the plants will \

4 \ således på grund af geotropisme og passende vandbalance søge nedad og ud gennem det åbne hul og ned i underlaget 10. Nu foregår der så jævnligt ifølge opfindelsen en rodbeskæring gennem overskæring af rød-5 deme i planet mellem dyrkningsmediet og dyrkning sunderlaget.Thus, due to geotropism and appropriate water balance, search downwards and out through the open hole and down into the substrate 10. Now, according to the invention, a root pruning takes place by cutting the reddish in the plane between the culture medium and growing the substrate.

Overskæringen af rødderne kan f.eks. ske gennem en relativ bevægelse af nettet 11 og underlaget 10, det 10 vil sige i praksis ved at bevæge nettet 11 hen over underlaget 10.The cutting of the roots can e.g. is effected by a relative movement of the web 11 and the substrate 10, i.e. in practice by moving the web 11 over the substrate 10.

Overskæringen kan også ske ved at bevæge et egnet skæreorgan, som f.eks. en kniv, en tråd, eller lig-15 nende, vandret hen mellem nettet 11 og underlaget 10. I det viste eksempel tænker man sig en bevægelse af skæreredskabet 14 i pilens Ά retning, i hvilket tilfælde det er nødvendigt, at netlængderne overlapper i én og samme retning, som nævnt ovenfor.The cutting may also be done by moving a suitable cutting means, such as e.g. a knife, a wire, or the like, traveling between the net 11 and the base 10. In the example shown, a movement of the cutting tool 14 in the direction of the arrow tæn is envisaged, in which case it is necessary that the net lengths overlap in one and the same direction, as mentioned above.

Det bør fremhæves, at planternes rodspidser, foruden at de forgrener sig rigt nedad, forhindres i at udvikle sig langs siderne og i hjørnérné på det vandtætte yderlag, da fugtforholdene er mere gunstige 25 nedadtil mod underlaget end ud mod det vandtætte y- derlag.It should be emphasized that the root tips of the plants, in addition to branching richly downwards, are prevented from developing along the sides and in the corners of the waterproof outer layer, as the moisture conditions are more favorable downwards towards the substrate than outwards against the waterproof surface.

Eksemplet i fig. 2 ligner meget det, der illustreres i fig. 1, men adskiller sig derfra ved at dyrknings-30 midlet nu består af sammenhængende dyrkningsbeholde re 16 i pyramidefacon. Denne form for dyrkningsbeholder anbringes på to net 17 og 18 mellem hvilke skæreorganet 14 bevæges i pilens retning A for at foretage rodbeskæring ved overskæring i planet mel-The example of FIG. 2 is very similar to that illustrated in FIG. 1, but differs therefrom in that the culture medium now consists of continuous culture vessels 16 in pyramid shape. This type of culture vessel is placed on two nets 17 and 18 between which the cutting means 14 is moved in the direction of the arrow A to perform root pruning by cutting in the plane between

I dette eksempel vil det sandsynligvis også være muligt at foretage overskæring af rodspidserne ved en 5 relativ bevægelse af nettene 17 og 18 med passende mellemrum.In this example, it will probably also be possible to cut the root tips by a relative movement of the nets 17 and 18 at appropriate intervals.

I begge eksempler placeres der naturligvis et meget stort antal dyrkningsenheder side om side på nette-10 ne, måske adskillige tusinde.Of course, in both examples, a very large number of cultivation units are placed side by side on the nets, perhaps several thousand.

I eksemplet i fig. 3 er der i bunden af drivhuset 19 skabt et egnet dyrkningsunderlag 20 f.eks. indeholdende groft grus, hvorpå der er anbragt et plastnet 15 med passende maskestørrelse. Derpå er der på dette plastnet lagt netstykker 21, f.eks. på almindelig pallestørrelse, 80 x 120 cm. På hvert af disse netstykker er der anbragt en masse dyrkningsbeholdere i lighed med den, 16, der vises i fig. 2.In the example of FIG. 3, a suitable cultivation support 20 is created at the bottom of the greenhouse 19, e.g. containing coarse gravel on which is placed a plastic mesh 15 of suitable mesh size. Then, on this plastic mesh, grid pieces 21, e.g. on standard pallet size, 80 x 120 cm. A plurality of cultivation vessels similar to that of 16 shown in FIG. 2nd

Langs siderne i drivhuset er der monteret skinner 23 til en tværgående hængekran 24, som bærer et skematisk fremstillet skæreorgan 25 til rodbeskæring ved undersiden af netstykkerne 21 på en måde, der svarer 25 til den, der er beskrevet ovenfor med henvisning til fig. 2. Skæreorganet kan gå hele vejen tværs over drivhuset eller det kan være af en sådan længde, at det udfører rodbeskæring på én langsgående sektion ad gangen, som vist i fig. 3.‘ Den tværgående kran 24 30 kan være forsynet med dyser 26 til vand, gødning, bekæmpelsesmidler, såsom insektdræber, osv. Desuden kan kranen være forsynet med en løfteanordning 27, der kan klare udlægningen af netstykkerne, hvorpå dyrkningsbeholdere anbringes, samt løftning og fjer- \Along the sides of the greenhouse, rails 23 are mounted to a transverse suspension crane 24 which carries a schematically produced cutting means 25 for root pruning at the underside of the grid pieces 21 in a manner similar to that described above with reference to FIG. 2. The cutting means may extend all the way across the greenhouse or it may be of such length as to perform root pruning on one longitudinal section at a time, as shown in FIG. The transverse crane 24 30 may be provided with nozzles 26 for water, fertilizers, pesticides such as insecticides, etc. In addition, the crane may be provided with a lifting device 27 capable of supporting the laying of the net pieces on which cultivation containers are placed, as well as lifting and feather-

Fig. 4 illustrerer tre dyrkningsbeholdere, der hver 5 har et yderi ag 33 hvorunder der findes et egnet dyrkningsmedium (34, fig. 5), som f.eks. kan bestå af tørvemos, mineralholdig jord, mineraluld eller en passende blanding af disse. Dyrkningsmediet kan også indeholde gødning og bekæmpelsesmidler, såsom svarn-10 pedræbende midler, osv.FIG. 4 illustrates three culture vessels, each having an outer ag 33, under which a suitable culture medium (34, Figure 5), such as e.g. may consist of peat moss, mineral-containing soil, mineral wool or a suitable mixture thereof. The culture medium may also contain fertilizers and pesticides such as antifungal agents, etc.

Beholderne 33 kan bestå af en formpresset blanding af tørvemos og cellulose udformet som kvadratiske pyramidestubbe, men andre udformninger er imidlertid 15 også mulige. Det er dog mest hensigtsmæssigt, hvis beholderne er udformet på en sådan måde, at "bund" overfladen 35, fig. 5 er betydeligt større end "top" overfladen 36, fig. 4 og 5. Enhederne, anbragt side om side som vist i fig. 4, forsynes med et egnet o-20 verfladelag, som efter tørring eller hærdning, dan ner de omtalte beholdere. De enkelte dyrkningsenheder, der på stedet forsynes med overfladelaget, kan siden adskilles fra hinanden, inden der lægges frø eller sættes stiklinger i dem.Containers 33 may consist of a molded mixture of peat moss and cellulose formed as square pyramid stumps, but other configurations, however, are also possible. However, it is most convenient if the containers are designed in such a way that the "bottom" surface 35, FIG. 5 is considerably larger than the "top" surface 36; FIG. 4 and 5. The units, arranged side by side as shown in FIG. 4, is provided with a suitable surface layer which, after drying or curing, forms the said containers. The individual cultivation units, which are provided with the surface layer on site, can then be separated from each other before seeds or cuttings are placed in them.
