Abstract
Abstract The present germination and seedling promoting unit includes an envelope containing a piece of preferably compressed moisture absorbing material such as peat for holding the seed or seeds. The bottom side of the envelope is provided with holes for absorbing ground moisture. The top surface of the envelope is provided with passage means for the growing seedling. Between the passage means and the seed or seeds there are provided mechanical protection means as well as evaporation protection means which are preferably formed as a web on a piece of tape, portions of which are taped to the peat to locate the protection means between the seed and the passage means.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
177 words
A germination and seedling promoting unit, especially for forest cultivation, comprising a moisture absorbing mass, one or more seeds in said mass adjacent to a first surface of the mass, an evaporation proof envelope substantially enclosing said mass, opening means in said envelope adjacent to a second surface of said mass for absorption of ground water by said mass through said opening means, seedling passage aperture means in said envelope adjacent to said first surface of the mass, evaporation protection means located between said seed or seeds and said seedling passage aperture means, and mechanical protection means for said seed or seeds located between said seedling passage aperture means and said seed or seeds, said mechanical protection means comprising a plurality of gradually decomposable wires and means for holding said gradually decomposable wires and the evaporation protection means in place against the moisture absorbing mass and over the seed or seeds, said means for holding including a layer of paper provided with holes for the seedlings, said paper layer overlapping the evaporation protection means and said mass.
Claim 2
Dependent Claim
177 words
A germination and seedling promoting unit, especially for forest cultivation, comprising a moisture absorbing mass, one or more seeds in said mass adjacent to a first surface of the mass, an evaporation proof envelope substantially enclosing said mass, opening means in said envelope adjacent to a second surface of said mass for absorption of ground water by said mass through said opening means, seedling passage aperture means in said envelope adjacent to said first surface of the mass, evaporation protection means located between said seed or seeds and said seedling passage aperture means, and mechanical protection means for said seed or seeds located between said seedling passage aperture means and said seed or seeds, said mechanical protection means comprising a plurality of gradually decomposable wires and means for holding said gradually decomposable wires and the evaporation protection means in place against the moisture absorbing mass and over the seed or seeds, said means for holding including a layer of paper provided with holes for the seedlings, said paper layer overlapping the evaporation protection means and said mass.
Claim 3
Dependent Claim
15 words
The unit according to claim 1, wherein said gradually decomposable wires are made of iron.
Claim 4
Dependent Claim
16 words
The unit according to claim 1, wherein said evaporation proof envelope is made of plastic material.
Claim 5
Dependent Claim
18 words
