SE454735B - Seed ampoule for tree cultivation - Google Patents

Abstract

The seed ampoule for tree cultivation comprises a pellet (1) of peat litter or similar in which the seed (2) is contained. The upper and lower ends (3,4) of the ampoule are of peat litter pulp with a mixture of nutritional material. At least the lower part (4) of the ampoule is contained in a casing (5) of newspaper or similar with high water absorption properties.

Description

454 735 The invention is described in more detail below in connection with an exemplary embodiment and the accompanying drawing, in which - Fig. 1 schematically shows a vertical and longitudinal section through an embodiment of a seed ampoule acc. the invention, Fig. 2 shows the ampoule according to Fig. 1 seen from above in Fig. 1. In Fig. 1, 1 denotes a so-called pellet with preferably substantially cylindrical shape, which pellet consists of compacted peat soil mass or the like with fertilizers involved. Said pellet 1 comprises at least one seed 2 of the desired type, such as a pine seed or spruce seed. Said pellet is arranged in one, upper end 3 of the ampoule.

The other, lower part Å of the ampoule consists essentially of peat soil mass or the like with admixture of fertilizers, where also the lower part 4 is preferably substantially cylindrical with substantially the same diameter as said pellet 1. At least the lower part Ä is surrounded at least longitudinally, vertically, by a cover 5 of newsprint or the like with high water absorption capacity.

Suitable dimensions of the ampoule 1, 2, h, 5 are a total length, height, of 40 - 60 cm and a diameter of 10 - 15 cm, where said pellet 1 constitutes 15 - 25% of the length, height of the ampoule.

Since the germination of the seeds is not 1002, it is preferable that said pellet 1 comprises two seeds, where these are arranged diametrically or correspondingly in relation to each other and some or a few centimeters inside the pellet wall 6 facing the casing 5, i.e. mantle surface 6, in order during the first years to reduce the mutual influence of the seeds and later the plants if both seeds germinate.

The function of the seed ampoule according to the invention should be apparent in part.

The ampoule 1,2, fi, 5 is thus lowered into a substantially vertical, for example drilled, hole in the ground 7, Fig. 1, with said pellet 1 upwards so that its upper surface 8 ends up approximately at ground level 9. Thereafter it is watered so that the pellet and peat soil becomes completely soaked. The seed / seeds 2 now germinate and can grow rapidly with the aid of the starting water in the peat soil, which is extremely moisture-retaining and non-draining, and the casing and the fertilizers involved, such as urea. The peat soil, which also preserves for a long time through precipitation-supplied water, constitutes a slightly forced channel for a frozen growing central root, through which channel the root can quickly reach down to naturally water-bearing soil. Due to the high water-absorbing capacity of the cover S, the packaging 5, its strength after watering, its strength after watering becomes sufficiently low for side roots to be able to easily penetrate the cover 5 of newsprint or the like.

In the event that both seeds would germinate, one of the growing plants should take over relatively soon. In this way, natural thinning takes place. When required, thinning can be done by cutting off the weaker plant.

By means of a seed ampoule acc. The invention for forest cultivation enables direct planting of seeds, whereby the stage of plant cultivation in greenhouses or the like, with this costs and disadvantages, is eliminated. In many cases, the need for pre-preparation, machining, of the soil around the planting site should also be eliminated.

For adjusting the length, height of the ampoule, to a given hole depth, such as when the hole p.g.a. rock or the like cannot be made as deep as the ampoule. is high, a part of the lower part of the ampoule can be easily cut off at its lower end.

Of course, more embodiments and minor changes are conceivable without departing from the spirit of the invention.

Thus, a perforated heel can be used. Furthermore, in some cases ampoule dimensions other than those specified above may be appropriate. In addition, in some cases a substantially conical ampoule shape may be suitable.

The invention is thus not to be considered limited to the above-mentioned embodiments but can be varied within the scope specified by the appended claims.
