Description

AGRICULTURAL AND/OR HORTICULTURAL GREENHOUSE FOR CROP PRODUCTION
The invention relates to an agricultural and/or horticultural greenhouse for crop production, in which elongated cultivating beds for the crop are arranged parallel to each other in the greenhouse. Such an agricultural and/or horticultural greenhouse is also referred to as a "Dutch- type" greenhouse in practice. The invention relates in particular - but not exclusively - to an agricultural and/or horticultural greenhouse of the "Venlo house" type, in which vegetables, fruit or flowers (in particular roses) are grown.
Such an agricultural and/or horticultural greenhouse is generally known, it is. usually built up. of columns, trusses connecting said columns, gutters supported by said columns and said trusses, as well as a sloping iroof extending between two gutters, which consists of a ridge section, glazing bars and panes. Said gutters and glazing bars form structural elements that must take up the weight of the roof as well as the loads caused by wind and snow. The known greenhouse is used in particular for growing vegetables, fruit or flowers and the like. Elongated cultivating beds are to that end arranged side by side in the greenhouse.
A general drawback of an agricultural and/or horticultural greenhouse of the type as referred to in the introduction is that the surface area of the greenhouse is not optimally utilised. The fact is that working corridors are present between the cultivating beds for carrying out all kinds of cultivating activities, such as pruning and harvesting. The object of the invention is to obviate the above drawback of the prior art and in particular to provide an agricultural and/or horticultural greenhouse in which the area of the greenhouse is utilised more effectively from a grower's perspective.
In order to accomplish that object, an agricultural and/or horticultural greenhouse of the kind referred to in the introduction is according to the invention characterized in that at least one cultivating bed is movably disposed in the greenhouse for the purpose of forming a working corridor therein. This makes it possible to place more cultivating beds in the greenhouse than usual and thus utilise a larger part of the area of the greenhouse for cultivating the crop. After all, the cultivating bed is moved so as to form a working corridor at that location, and moved .back again upon completion of the cultivating activities in question. Conseguently, the invention is in particular based on the idea of forming a working corridor by means of a movable cultivating bed only when this is actually necessary in connection with cultivating activities to be carried out.
In a preferred embodiment of an agricultural and/or horticultural greenhouse according to the invention, at least two groups of cultivating beds for the crop are arranged parallel to each other in the greenhouse, wherein a working corridor has been left clear between an outer cultivating bed of one group and an outer cultivating bed of the other group, and wherein at least one additional cultivating bed can be moved in vertical direction (downwards and upwards) between a first position, in which the additional cultivating bed is positioned above the working corridor, and a second position, in which the additional cultivating bed is positioned in the working corridor. A group comprises n cultivation beds, wherein n = 1,2,3... In practice the house comprises several^ stationary cultivating beds arranged in groups of two or more cultivating beds in the greenhouse, and working corridors are left clear between neighbouring groups of cultivating beds . The additional cultivating bed is positioned in the working * corridor during the growing process of the crop, whilst the additional cultivating bed is moved upwards when cultivating activities, such as pruning and harvesting, are to be carried out so as to form a working corridor for the grower, upon completion of the cultivating activities, the additional cultivating bed is lowered into the working corridor again.
In another preferred embodiment of an agricultural and/or horticultural greenhouse according to the invention, at least two cultivating beds for the crop are arranged parallel to each other in the greenhouse, wherein a working corridor has been left clear between an outer cultivating bed of one group and an outer cultivating bed of the other group, and wherein at least one additional cultivating bed can be moved in horizontal direction (sideways) in the working corridor between a first position, in which the additional bed faces towards the outer bed of one group, and a second position, in which the additional bed faces towards the outer bed of the other group. A group comprises n cultivation beds, wherein n = 1,2,3... Instead of moving the additional cultivating bed in vertical direction, as set forth above, a horizontal movement of the additional cultivating bed now takes place, viz. from, said first position to said second position, and vice versa. As is the case with a vertical movement, the additional cultivating bed only needs to be moved between groups of (often stationary) cultivation beds when this is necessary for forming a working corridor so as to enable the grower to carry out the required cultivating activities.
In another preferred embodiment of an agricultural and/or horticultural greenhouse according to the invention, the movable cultivating bed is suspended from the top of the greenhouse. In that case the greenhouse will in particular be a greenhouse whose structural framework is built up of rows of a vertical columns as well as horizontal trusses that interconnect the columns of one row, wherein the movable bed is suspended near a horizontal truss, for example from a girder that extends below the truss. Preferably, a pull/push device mounted on the horizontal truss is provided, which is capable of pulling/pushing the movable cultivating bed forward and backward in horizontal direction.
In another preferred embodiment of an agricultural and/or horticultural greenhouse according to the invention, the cultivating beds are in the form of substrate troughs. The substrate troughs are made of a metal and/or a plastic material and contain a substrate on which the crop in question is cultivated. To provide the crop with the necessary water - with the possible addition of nutrients - an irrigation system mounted above the substrate troughs is provided, in particular a drip system. In another preferred variant, an ebb-flood irrigation system is used.
The invention also relates to a movable cultivating bed obviously suitable for use in an agricultural and/or horticultural greenhouse according to the invention.
The invention will be explained in more detail with reference to figures illustrated in a drawing, in which Figure 1 is a schematic, perspective view of a part of an agricultural and/or horticultural greenhouse of the "Venlo house" type, in which the present invention can be implemented; and
- Figure 2 is a schematic cross-sectional view of the house of figure 1, which shows how the invention works.
A "Venlo house" 1 as shown in figure 1 comprises a supporting structure consisting of vertical columns 2 and horizontal trusses 3 that interconnect the columns 2. The rows of columns 2 connected by the trusses 3 may furthermore be interconnected by gutters 4. Each pair of gutters 4 lying side by side bounds a roof 5 of the "Venlo house" 1. Various driving devices may be mounted at the top of the "Venlo house" 1, such as a driving device 6 for opening and closing windows 7 mounted in the roofs 5. Furthermore, a driving device (not shown) may be provided for operating screens (not shown) mounted at the top of the "Venlo house" 1, which function to protect crops being cultivated in the "Venlo house" 1 against fierce sunlight and to limit loss of heat via the roofs 5 as much as possible.
Figure 2 schematically shows the "Venlo house" 1 of figure 1 in cross-sectional view. In the "Venlo house" 1, several groups 8 comprising stationary two substrate troughs 9 for cultivating rose bushes 10 thereon are disposed parallel to each other (seen in the longitudinal direction of the "Venlo house" 1) . Working corridors or paths 11 have been left clear between outer substrate troughs 9' of respective first groups 8 and outer substrate troughs 9 ' ' of respective second (adjacent) groups 8. According to a preferred variant of the invention, at least one additional substrate trough 13 is movably (in horizontal direction) disposed in each path 11. In other words, the movable substrate trough 13 can be moved% in horizontal direction {seen in the transverse direction of the "Venlo house" 1) between a first (left-hand) position, in which the additional substrate trough 13 faces towards the outer substrate trough 9' of the first group 8, and a second (right-hand) position, in which the additional substrate trough 13 faces towards the outer substrate trough 9'1 of the second ( adjacent ) group 8. In the first position of the substrate trough 13, cultivating activities can be carried out on the right-hand side, i.e. on the outer substrate trough 9 ' ' , whilst in the second position of the substrate trough 13 cultivating activities can be carried out on the left-hand side (i.e. on the outer substrate trough 91). The horizontal forward and backward movement of the substrate trough 13 is realised by. suspending the substrate trough 13 from a girder 14 that extends below a truss 3 and subsequently pulling/pushing the substrate trough 13 forward and backward by means of an electrically driven push/pull device 15. The push/pull device 15 moves along the aforesaid girder 14, therefore, and is mounted thereon.
It is noted that some activities, viz. the so-called disbudding and bending of the rose bushes 10, are carried out in two operations: in the case of a left-hand position of the additional substrate trough 13, work is carried out on the outer (right-hand) substrate trough 9f ' of the second group 8 in the first operation while work is carried out the other substrate trough of said group in the second operation. The same applies with regard to a right-hand position- of the additional substrate trough 13, mutatis mutandis. After the cultivating activities have been carried out, the additional substrate trough 13 is placed in a third (central) position or position of rest, viz. at least substantially in the centre of the path 11. When the rose bushes 10 grow further upwards, it may be desirable in connection with pruning activities to move the substrate trough 13 slightly upwards as well (for example by a distance of about 20 cm), viz. by' means of a union construction 16.
It is preferable to provide five groups 8, each consisting of two substrate troughs 9, for each girder width of about 4.5 m in the "Venlo house" 1, with a path 11 having a width of about 80 cm being present between respective groups. Such a path 11 is readily passable for a grower with a tube rail harvesting trolley (width about 35 cm) . Using the pull/push device 15, the substrate trough 13 can be moved about 34 cm to the left (corresponding to the aforesaid first . (left-hand) position of the substrate trough 13) as well as about 34 cm. to the right (corresponding to the aforesaid second (right- hand) position of the substrate trough 13) from the aforesaid third (central) position.
Using the invention, the path 11 is only clear for cultivating activities when this is necessary, for the rest the path 11 is utilised for cultivating the rose bushes 10. In this way a production increase of up to 50% is achieved in the "Venlo house" 1.
It is noted that the invention is not limited to the embodiment that is shown herein, but that it also extends to other preferred variants that fall within the scope- of the appended claims. Thus it will be apparent to those skilled in the art that the additional substrate trough 13 can also be moved in vertical direction instead of in horizontal direction.
