Abstract
A germinator is formed by locating a plastic sheet cover around a textile material, preferably plant-"Fibertex".RTM., being in contact with a seed, a sprout or a cutting. As a consequence of its distinct capillary effect the textile material ensures the sufficient amount of moisture during the beginning germination of a seed, and after bedding out of the germinated plant the surrounding plastic sheet cover protects the root or the roots against drying up for the first few days after the bedding out.

Description
The present invention relates to a germinator and the use of textile material for the production of a germinator.
In the growing of plants on the basis of planting stock capable of germinating, preferably seeds, said planting stock being developed far from the place of growing of the plants, it has long been known to use the so-called seed tapes. These seed tapes are put into the soil, and by virtue of the mutual distance of the seeds in the soil they ensure that the plants come up at an appropriate mutual distance in such a manner that the plants do not influence each other with respect to absorbtion of water and nutrients. It is generally known that the beginning germination of the seeds is of decisive importance for a normal developing phase of the plants since unfavourable circumstances at the beginning germination have turned out to imply partly that many seeds do not germinate, and partly that the remaining germinating seeds result in plants not developing completely during otherwise good growing conditions, i.e. plants not yielding the crop usually achievable.
Thus it turned out that producers in countries like Saudi-Arabia and Kuwait only obtain a plant growth corresponding to the seeds being capable of germinating as far as 50% are concerned when putting down seed tape comprising seeds appearing to be capable of germinating as far as 95% are concerned at a preceding control.
The low germinating percentage appeared to derive directly from lacking moisture during the beginning germination of the seed, and the object of the invention is therefore to overcome this problem.
Accordingly the invention deals with a germinator which is characterized by a plastic sheet cover around a textile material, preferably plant-"Fibertex".RTM., being in contact with a seed, a sprout or a cutting.
As textile material any textile may be used which possesses the property that supply of water to one spot on the textile material ensures distribution of water in the remaining part of the material as a consequence of a distinct capillary effect through the material.
The so-called plant-"Fibertex".RTM. is an example of such a material.
An embodiment of the germinator according to the invention is characterized by the plastic sheet cover surrounding a strip-shaped textile material like a sleeve open at both ends and in the flattened state having dimensions corresponding to the extension of the textile material.
The textile material may comprise one or more layers and can thus comprise two coherent layers folded about the seed, the sprout or the cutting.
In the flattened state the germinator may have a width of from about 2 to about 5 cm and a length of from about 4 cm to several meters.
The germinator according to the invention may be produced in different ways, e.g. as a tape through welding or gluing of two plastic sheet layers located on top of each other in areas of a width of a few mm transversely to the tape length, a perforation or another weakening line being produced in connection with the glueing or the welding for the separation of the individual germinators at the tearing off from the tape. The strip-shaped textile material may be inserted in the channels formed between the two plastic sheet layers upon the welding or the glueing, and they may also be located correspondingly prior to the welding or the glueing.
The seeds may be introduced into the germinators simultaneously with the textile material, but a separate introduction is also possible. All the above steps in the process of producing a germinator according to the invention may be carried out industrially in fully automatic production plants.
The germination of the seeds inserted in the germinators and located a few mm from the upper end of said germinators, is preferably carried out by locating the germinators in a layer of sand in such a manner that they incline about 45.degree. relative to the vertical direction and with the upper end of the germinators almost flush with the surface of the layer of sand.
The raising may subsequently take place by means of drip-watering, a plastic sheet being located under the layer of sand so as to maintain the moistness. When the sand has reached an appropriate moistness at the lower end of the germinators, the textile material ensures as a consequence of its distinct capillary effect an appropriate and continuous moistness around the seeds and the roots gradually growing downwards through the germinators and finally reaching the layer of sand under the germinators.
The germinating plants are subsequently ready for bedding out on the places of the actual development and growth, and the germinators are now located vertically in the soil with their upper ends almost flush with the surface of the soil. The purpose of the plastic sheet cover is now to protect the root against drying up in the first few days after the bedding out, and according to the plant or kind of wood in question and to the nature of the soil the cover must be of such an appropriate length that the lower end is located so deeply in the soil that the projecting plant roots are in constant contact with moist soil. p In this manner the maximum number of seeds germinate, and by means of the germinator according to the invention it turned out to be possible to make almost 100% of the planted germinators grow into completely developed plants.
Furthermore, the germinator according to the invention turned out to permit attainment of particularly good crop results on the basis of a predetermined number of seeds capable of germinating, e.g. cucumber seeds and sugar beet seeds. Wood seeds of various kinds of wood also turned out to be suited for use in germinators according to the invention, including such kinds of wood seeds which upon an appropriate germination and succeeding development prior to the bedding out are bedded out on areas far from the germination place.
The textile material forming part of the germinator according to the invention acts so to speak as a root extender ensuring the necessary supply of moisture to the plant at its beginning developing steps, whereby dry periods otherwise could be destructive to the further development.
The invention furthermore relates to the use of textile material, preferably plant-"fibertex".RTM., as moistening contact material for or as cover around a seed, a sprout or a cutting, for the production of a germinator.
