Abstract

A plant shelter to be arranged in connection with a top of a plant (2), particularly a pine plant. The plant shelter has an open top and an open bottom and a shape like that of a downward tapering cone. The plant shelter is dimensioned such that its inner diameter enables the plant shelter (1) to retain its place owing to a needle pressure caused by needles (3) of the plant (2) onto the inner surface of the plant shelter (1).

Description

PLANT SHELTER
The invention relates to a plant shelter to be arranged in connection with a top of a plant, the plant shelter having an open top and an open bottom. Annually, deer cause considerable damage to plantations, particu- larly pine plantations. The animals particularly feed on top parts of the plants and may thus destroy an entire plantation. Shelters which project from the ground have been developed in order to prevent the damages. The shelters have to be even 2.5 m in height in order to prevent the large deer from being able to reach the plant tops. Being large, such plant shelters are difficult to install and use; they are expensive as well. Furthermore, the plant shelters cause the deer to move to another area when the sheltered plants do not provide the animals with food. It is then likely that plantations will be damaged in some other area while, on the other hand, the migrating deer disturb the ecological balance in the area. Furthermore, cylindrical plant shelters made e.g. of a meshy material are known which are to be wound around the plant tops. Such plant shelters are mainly designed to shelter plant tops of deciduous trees. Such plant shelters are difficult and expensive to use and they are also quite expensive to manufacture. An object of the present invention is to provide a simple and easy- to-use plant shelter to shelter plant tops.
The plant shelter of the invention is characterized in that the plant shelter is shaped like a downward tapering cone and in that the inner diameter of the plant shelter is dimensioned such that the plant shelter can be arranged to retain its place owing to a needle pressure caused by needles of a plant onto the inner surface of the plant shelter.
The idea underlying the invention is that the plant shelter is to be arranged in connection with a plant top and that it is shaped like a downward tapering cone. A further idea underlying the invention is that the inner diameter of the plant shelter is dimensioned such that the plant shelter retains its place owing to a needle pressure caused by the needles of a plant onto the inner surface of the plant shelter. The idea of a preferred embodiment is that the plant shelter comprises an opening for ventilation. The idea of a second preferred embodiment is that the plant shelter is made of a biodegradable mate- rial. An advantage of the invention is that the plant shelter shelters the tops from deer damage while the deer are allowed to feed on side branches, which means that the deer are provided with food without having to migrate, whereby the ecological balance in the area will not be disturbed. The plant shelter of the invention is simple, easy to manufacture and quite small. Since the plant shelter retains its place owing to the needle pressure, the plant shelter does not cause any pressure to the stem of the plant but an air gap is provided between the plant shelter and the stem, which prevents the plant from suffocating. While melting, snow in the form of water in the plant shelter is al- lowed to flow out from between the plant shelter and the stem, so the snow load collected by the plant shelter will not break the top of the plant. Furthermore, since the plant shelter is kept in place by the needle pressure, the plant shelter may be quite short, i.e. it does not have to be e.g. of the length of an annual shoot of the plant. The plant shelter of the invention is easy to install in its place and being shaped like a downward tapering cone, when arranged around the plant, it can be readily lifted onto a new annual shoot grown by the plant.
The invention will be described in closer detail in the accompanying drawing, which shows a schematic and cross-sectional side view of an in- stalled plant shelter of the invention.
The figure shows a plant shelter 1 provided with an open top and an open bottom and shaped like a downward tapering cone. The definition "shaped like a downward tapering cone" refers to the fact that the diameter of the plant shelter is smaller at its lower end than at its top end. Furthermore, the cross-section of the plant shelter 1 may also have a shape resembling that of a triangle or another polygon. The cross-section of the plant shelter 1 may also be circular.
The figure further shows a top part of a plant 2, the plant shelter 1 being arranged to shelter the top of the plant 2. The plant shelter 1 is dimen- sioned such that needles 3 press against the inner surface thereof, retaining the plant shelter 1 in its place. It is thus the needle pressure caused by the needles 3 against the inner surface of the plant shelter 1 that keeps the plant shelter 1 in place. The plant shelter 1 is particularly usable in connection with pine plants whose needles are quite long and strong. Since the plant shelter 1 is kept in place by the needle pressure, a gap can thus exist between the plant shelter 1 and the plant 2 to ensure suffi- cient ventilation. Furthermore, while melting, the snow accumulated inside the plant shelter 1 can easily flow out through the gap between the plant shelter 1 and the plant 2. The smallest diameter of the plant shelter 2 is preferably more than 3 cm, in which case the air passage between the plant shelter 1 and the plant 2 remains large enough. On the other hand, the smallest diameter of the plant shelter 2 is preferably less than 8 cm, in which case the needle pressure caused by the needles 3 keeps the plant shelter 1 in its place. Since the plant shelter 1 retains its place owing to the needle pressure, the plant shelter 1 does not have to be installed to be supported by side branches, which means that it can be even considerably shorter than an annual shoot 4. The height of a typical plant shelter of the invention is about 16 cm, the diameter of the lower part being about 6 cm and the diameter of the top part being about 9 cm.
The conical, downward tapering plant shelter 1 by no means prevents the plant 2 from growing. In the figure, broken lines illustrate a previously installed plant shelter, after the installation of which the plant 2 has grown upwards. Since the plant shelter 1 is shaped like a downward tapering cone, after the plant 2 has grown to some extent the plant shelter can easily and simply be lifted from the position indicated in a broken line into the position indicated in an unbroken line in the accompanying figure. The point of time when the plant shelter 1 is moved upwards is determined according to the point of time when deer typically dwell in the area of a sheltered plantation.
One or more openings 5 can be arranged in the plant shelter 1 to ensure ventilation. Preferably, the openings 5 are elongated. The plant shelter 1 is preferably made of a biodegradable material, such as a mixture of poly- propylene and pine oil. The plant shelter 1 can be arranged such that it decomposes e.g. within a few years. It is thus unnecessary to separately go and remove the plant shelter 1 from around the plants 2. The elongated opening 5 promotes the decomposing process of the plant shelter 1. In order to make sure that the plant shelter 1 will decompose, in addition to or in place of the opening 5, the plant shelter 1 can also be provided with reductions or perforations or other such impairments.
The description and the related figure are only intended to illustrate the idea of the invention. In its details, the invention may vary within the scope of the claims.
