Abstract

The invention relates to a device for preventing insects and larvae, especially pine weevils, bark beetles and the like, from attacking pine and fir plants and the like, comprising a sheath which encloses the plant. The novelty of the invention is that the device, which consists of thin, relatively rigid film material, which is constituted such that its resistance is reduced after a predetermined time, comprises an essentially cylindrical jacket section 1, which is closed at the top, a number of narrow slits 5, which are arranged along the jacket section and which are delimited by inwardly crimped-over flanges 6, 7, a seat 3, 4, which is located at the bottom, for a seed or, respectively, plane carrier 11, which can be fitted in the cylindrical section, is expediently cup-shaped and is preferably made of natural materials, and flaps 10, which are arranged at the bottom, which project obliquely from the cylindrical section and which are intended to form supporting and retaining members which interact with the ground material and which stabilise the device. <IMAGE>

Ett utföringsexempel på anordningen enligt uppfinningen och ett parti av ett verktyg för densammas utplacering kommer i det följande att närmare beskrivas med hänvisning till den bifogade ritningen, pâ vilken fig 1 är en delvis genomskuren sidovy av anordningen i fråga, fig 2 är en delvis genomskuren ändvy av samma anordning och fig 3 är en genomskuren sidovy av nedre änden av anordningen jämte verktyget för densammas applicering, varvid verktyget visas i två lägen.An exemplary embodiment of the device according to the invention and a portion of a tool for its placement will be described in more detail below with reference to the accompanying drawing, in which Fig. 1 is a partially sectioned side view of the device in question, Fig. 2 is a partially sectioned end view. of the same device and Fig. 3 is a sectional side view of the lower end of the device together with the tool for its application, the tool being shown in two positions.

Anordningen enligt uppfinningen består av ett väsent- ligen cylindriskt mantelparti 1. Detta är vid sin övre ände tillslutet medelst ett fast lockparti 2. vid nedre änden är ett par inâtskjutande inpräglingar 3 resp 4 an- ordnade. _ I .The device according to the invention consists of a substantially cylindrical jacket portion 1. This is closed at its upper end by means of a fixed lid portion 2. at the lower end a pair of projecting imprints 3 and 4 are arranged. _ I.

Utefter mantelpartiet 1 sträcker sig ett antal lång- sträckta slitsar 5, som i sidled avgränsas av inåtkragade flänsar 6 resp 7. Flänsarna har inåt avtagande tjocklek och bildar en så smal spalt att larver och insekter ej kan intränga genom desamma.Extending along the jacket portion 1 are a number of elongate slits 5, which are laterally delimited by inwardly collared flanges 6 and 7, respectively. The flanges have a decreasing thickness inwards and form such a narrow gap that larvae and insects cannot penetrate through them.

Vid nedre änden är mantelpartiet någon utvidgat, så att ett anslag 9 bildas. Bortom detta âterfinnes ett stort antal flikar 10, som lämpligen bildats genom att en cylind- risk förlängning av mantelpartiet uppskurits.At the lower end, the jacket portion is slightly widened, so that a stop 9 is formed. Beyond this there are a large number of flaps 10, which are suitably formed by cutting a cylindrical extension of the jacket portion.

Mellan inpräglingarna 3 och 4 bildas ett säte för en frö- resp plantbärare 11, som underifrån förs på plats.Between the imprints 3 and 4, a seat is formed for a seed or plant carrier 11, which is moved into place from below.

Genom att ett par av flikarna 10 bockas inåt och sam- manfogas bildas ett extra stopporgan 12 för bäraren 11.By bending a pair of the flaps 10 inwards and joining them together, an additional stop means 12 is formed for the carrier 11.

Anordningen enligt uppfinningen är avsedd att användas såväl under förgronings- och plantuppdrivningsstadiet som under planruríngsstradiut.The device according to the invention is intended to be used both during the germination and plant propulsion stage as well as during the planarization stage.

Fröet eller en förgrodd plantn kan antingen vara pla- cerat i den lämpligen med torvmull eller liknande fyllda 10 15 20 25 30 35 8002191-8 3 bäraren 11 eller i efterhand placeras däri. Under förgro- ningsstadiet resp under plantans första utvecklingsstadium kan anordningen vara placerad med locket 2 nedåt på ett lämpligt underlag, varvid vattning och annan behandling underlättas.The seed or a pre-germinated plant may either be placed in the suitably filled peat soil or similar carrier 11 or subsequently placed therein. During the germination stage or during the first development stage of the plant, the device can be placed with the lid 2 down on a suitable surface, whereby watering and other treatment are facilitated.

Vid planteringen användes med fördel ett verktyg av det i fig 3 visade slaget.When planting, a tool of the type shown in Fig. 3 is advantageously used.

Verktyget, som kan ingå i ett handverktyg men även bilda del av en mekanisk planteringsapparat, innefattar en första hylsa 13, i vilken anordningen placeras med den nedre flikförsedda änden utåt. Den inre hylsan kommer där- vid att ingripa med anslaget 9, vilken gör att anordningen med kraft kan hållas 1 anliggning mot marken.The tool, which can be included in a hand tool but also form part of a mechanical planting apparatus, comprises a first sleeve 13, in which the device is placed with the lower flapped end outwards. The inner sleeve will then engage with the stop 9, which means that the device can be held in force against the ground.

Utanpå den första hylsan 13 är en förskjutbar hylsa 14 anordnad och denna som kan vara försedd med en sågartad avsmalnande kant 15 hålles i ett första skede, varunder hylsan pressas mot marken, i det uppdragna till vänster på figuren visade läget. Den yttre hylsan 14 pressas därefter, samtidigt som anordningen hålles fast med den inre hylsan 13 nedåt, varvid den kommer att ingripa med flikarna 10 och pressa ner dessa genom markens ytskikt.A displaceable sleeve 14 is arranged on the outside of the first sleeve 13 and this, which may be provided with a saw-like tapered edge 15, is held in a first stage, during which the sleeve is pressed against the ground, in the position shown on the left in the figure. The outer sleeve 14 is then pressed, while the device is held with the inner sleeve 13 downwards, whereby it will engage with the flaps 10 and press them down through the surface layer of the ground.

När verktyget lyftes kommer flikarna 10 att liksom hullingar ingripa med markmaterialet och därmed fixera anordningen.When the tool is lifted, the flaps 10 will, like barbs, engage with the ground material and thereby fix the device.

Materialet, som användes för anordningen är lämpligen av sådan beskaffenhet att det inom förutbestämbar tids- rymd, genom inverkan från det ultravioletta ljuset brytes ner, blir sprött och när plantan nått lockpartiet 2 lätt kan brytas sönder.The material used for the device is suitably of such a nature that within a predetermined period of time, by the action of the ultraviolet light, it breaks down, becomes brittle and when the plant has reached the lid portion 2 can be easily broken.

Den för plantor kritiska perioden är det eller de första åren. En planta, som nått sådan storlek att den spränger anordningen löper ringa risk att utsättas för skadliga insektsangrepp.The period critical for plants is the first year or years. A plant which has reached such a size that it bursts the device runs little risk of being exposed to harmful insect infestations.

Den i anordningen inneslutna plantan tillföres er- forderlig fuktighet dels genom markfukt, som suges upp av odlingsmassan och dels genom regnvatten, som samlas på mantelns utsida och genom kapillärverkan intränger genom slitsarna. l8ÛÜ2191-8 4 Uppfinningen får ej anses begränsad till det beskrivna och på ritningen visade, utan kan modifieras på ett flertal sätt inom ramen för efterföljande patentkrav.The plant enclosed in the device is supplied with the necessary moisture partly by soil moisture, which is absorbed by the cultivation mass and partly by rainwater, which collects on the outside of the mantle and penetrates through the slits through capillary action. The invention may not be considered limited to what is described and shown in the drawing, but may be modified in a number of ways within the scope of the appended claims.
