Abstract: 1. A material for use in preparing a seedbed with the purpose of growing crops, where the material comprises two layers (2;5) of material not being able to be grown through and which are arranged for laying down to a level below the surface level of the seed-bed as they are extending from said level below the surface level to over the surface level of the seedbed, characterized in that a strip (1) which at least in some areas is able to be grown through by plants is interconnected with said two layers of material at said level below the surface level. 2. A material according to claim 1, characterized in that the two layers (2;5) of material not being able to be grown through are arranged to lie joined to each other and to extend vertically with said strip between them at their lower rim sections. 3. A material according to claim 1, characterized in that the strip is arranged to form the bottom in a U-shaped furrow, where the two layers (2;5) of material not being able to be grown through are arranged to form the sides in the furrow. 4. A material according to claim 3, characterized in that before, during, or after the laying down, the strip (1) is arranged for receiving plant seeds or small plants evenly distributed along the strip and a growing medium (4) which is free from weed seeds for wholly or partly filling up the U-shaped furrow. 5. A material according to claim 1, characterized in that the two layers (2;5) of material not being able to be grown through are fastened to each their rim of the strip (1). 6. A material according to claim 1, characterized in that the two layers (5;6) of material not being able to be grown through comprises a sheet shaped material. 7. A material according to claim 3, characterized in that the sheet shaped material (5;6) is relatively stiff and extends upward from the surface level of the seedbed after the laying out. 8. A material according to claims 1-7, characterized in that at the laying out, the two layers (2;5) of material not being able to be grown through comprise liquid substances which harden after the laying out and form a layer of material not being able to be grown through. 9. A material according to claims 1-8, characterized in that the strip comprises one or more of the following substances: hygroscopic material, microorganisms or substances increasing germination, fertilizing agents, substances inhibiting pests. 10. A material according to claim 1-10, characterized in that the strip comprises water-soluble paper. 11. A material according to claims 2-9, characterized in that a glue layer between the two layers of material not being able to be grown through forms the strip. 12. A method for controlling weed germination in seedbeds, characterized in that a strip (1) being able to be grown through by plants is provided, that two layers (2;5;6) of material not being able to be grown through are provided, that said two layers are connected, that the combined material is arranged so that said strip is placed under the surface level of the seedbed as plant seeds or small plants are provided on said strip before, during, or after the laying down of the combined material, and that said two layers are arranged to extend from the strip and to over the surface level of the seedbed, where the area above the strip (1) and between the layers (2;5;6) of material not being able to be grown through is filled up with a growing medium (4) being free from weed seeds. 13. A method according to claim 12, characterized in that the two layers are arranged so that they extend toward both sides of the strip (1) and are covered by a layer of soil where seeds of cultivated plants or small plants are placed in the row at the strip (1). 14. A method according to claim 12 or 13, characterised in that the two layers (5;6) of material not being able to be grown through at the placing of the strip under the surface level of the seedbed will extend upward over the surface level of the seedbed for protecting the crop against weed inhibiting measures externally of the two layers (5;6) of material not being able to be grown through. 15. A method according to claim 12 or 13, characterised in that the two layers of material not being able to be grown through at the placing of the strip under the surface level of the seedbed will extend along the surface level (3) of the seedbed for preventing germination of weed close to the row of crops. 16. A method for controlling weed germination in seedbeds, characterised in that there is established an elongated slot in the seedbed, and that in the slot there is set down a material consisting of two layers of material not being able to being grown through and which layers are connected at their lower rim by a strip (1) being able to be grown through by plants, and which combined material have or are supplied with seed of cultivated plants in the so-formed U- or V-shape, and that the slot hereafter is pressed together about the seed from the outside. 17. A method according to claim 16, characterised in that the two layers of material not being able to be grown through extend over the surface level of the seedbed toward both sides of the closed slot. 18. A method according to claim 16 or 17, characterized in that there is established a covering with clear plastic of the area around and over the cultivated plants.
