  • the resilient material is preferably soluble and sorbitol is indicated as suitable.
  • the seed capsule is preferably pressed with a higher pressure at the periphery.
  • a seed ampoule with one or more seeds embedded in peat or the like is described in SE-A-8 104 894-4. Further peat containing "fertilizer” etc. can be applied on any side of this seed capsule and at least this part is wrapped up in a piece of newspaper or a similar absorbent material.
  • Norwegian patent 148 977 teaches a seed carrier containing peat and fibrous material.
  • the fibrous material is preferably a cellulosic material or mineral fibers.
  • the peat and the fibrous material are prepared to a slurry, optionally together with the seeds, after which a sheet-like object is prepared, for example by usual papermaking technique.
  • the resulting "paper" with the seeds therein is the seed carrier.
  • Swedish patent 73 523 relates to a machine for preparation of briquettes containing seed.
  • the briquettes should be prepared from a suitable material and provided with holes into which earth, seed and finally earth again over the seed are introduced. The briquettes have apparently been pressed in usual manner at a low pressure.
  • the seed pellet consists of at least one seed in an organic substrate and, moreover, contains earth. Nutrients, organic fertilisers, fungicides, pesticides etc. can be present.
  • the organic substrate can consist of a plant material that is not lignified. Wetting agents may promote the wetting of the outer surface. One bitter principle is also included.
  • the pellet is also provided with a semi-permeable casing of a starch and/or latex. The pellets are prepared in that the material is mixed and thereafter pressed.
  • the moisture-retaining agent consists of 80-20% of peat and 20-80% of microcellulose and optionally a disintegrating agent up to an amount of 10% by volyme of the moisture retaining agent, the compound of moisture retaining agent and disintegrating agent being in the form of a tablet compressed under a pressure of at least 100 MPa and the possible protective layer around the seed capsule consisting of a water-soluble or water-swellable film.
  • the peat used has preferably been taken from a peat bog and pressed and/or dried in the usual way for use as additive to garden earth.

  • the microcrystalline cellulose is a partially depolymerized cellulose and has a levelled out degree of polymerization. As is apparent from its name it consists of microcrystals.
  • the microcrystalline cellulose used according to the invention has preferably been prepared by acid hydrolysis of cellulose (normally cellulose pulp that has been prepared from wood in usual manner). This acid-hydrolyzed cellulose with levelled out degree of polymerization is preferably ground and dried, for example by drying in bulk or by spray drying. A microcrystal of such a cellulose can for example have a size of 150 x 15 ⁇ 10 nm.
  • a suitable microcrystalline cellulose is that manufactured by FMC, USA, by the name of Avicell ® , for example Avicell ® PH.
  • the microcrystalline cellulose is preferably used in an amount of 30-70% by weight, preferably 40-60% by weight, for example 50% by weight, of the moisture retaining agent.

Abstract

Une capsule pour semences comprend un mélange qui est constitué par un agent de retention de l'humidité et par un agent de désintégration dans lequel sont incorporées une ou plusieurs semences. Le trou est bouché, c'est-à-dire que la capsule est par exemple recouverte au moins partiellement d'une couche protectrice. L'agent de retention de l'humidité comprend de 80 à 20 % de tourbe et de 20 à 80 % de microcellulose, et un agent de désintégration présent en une quantité allant jusqu'à 10 % en volume de l'agent de retention de l'humidité est de préférence mélangé à ce dernier. La couche protectrice éventuelle comprend une pellicule hydrosoluble ou hydrogonflable. On peut préparer cette capsule pour semences en mélangeant de la tourbe et de la cellulose microcristalline selon un rapport de quantité de 4/1 à 1/4, ainsi qu'éventuellement un agent de désintégration. Le mélange qui en résulte est ensuite comprimé sous la forme de tablettes, dans chacune desquelles est pratiqué au moins un trou, par exemple par poinçonnage ou par perçage, au moins une semence étant en outre introduite dans chaque trou et la tablette éventuellement recouverte d'une couche protectrice. Cette capsule pour semences est destinée à l'ensemencement, en particulier d'arbres tels que des conifères, la capsule pour semences étant placée sur la terre ou si possible à un niveau plus ou moins bas sous la terre.
