DE2013352A1 - Plant growth substrate plates - Google Patents

Abstract

Substrate plate system, in which plants are grown, has a foam cube with a cross slit, as in parent patent, which is nested in a larger cube when roots have grown through it, and so on successively. The cubes comprise base and side plates joined by water-holding gel adhesive, pref. based on acrolein polymers and alkali hydroxides to form a water conducting and damming film which interpenetrates the rooting medium.

System of substrate plates that intermeshes with the plants

The system of plant cultivation described below with a system adapted to the respective growth of the plants Enlargement of the substrate plate is a further development of the main patent file number P 19 ^ 7 18o "> "Pre-cut foam plant plate". According to the main patent, the cuttings or

Seeds inserted into cross slots, those in small ones Blocks of polyurethane foam are punched in, wherein a plurality of such plant blocks with the corners connected to form a plate, which a quick planting permitted. This plate is after the vortex divided into individual blocks by plucking them off and then piling them in garden soil. These planting plates are made according to de * Planting in plastic bowls standardized! ' Size or in place of corners laid and moistened with water.

This procedure is recognized to be of great help for commercial horticulture, since the planting in a finished substrate quickly and warping without damaging the roots can be done. However, it is felt to be disadvantageous that the warping should take place in garden soil, whose production and dressing is always too expensive.

It has now been suggested by a third party, the cuttings or to plant seeds in small lumps made of rigid foam and these cubes after rooting into a larger one Use the dice by taking the larger cube mech. presses in, i.e. destroys the cells of the rigid foam 'and

1098U / 0U0

insert the waiter's cube into the resulting recess. If the larger cube is also streaked, it is inserted into an even larger block of foam. This method has several disadvantages:

1. The use of rigid foam makes a compression of storage and shipping material impossible; a huge amount of space is required for storage and transportation.

2. When warping, the countersunk holes must be made in each block, which greatly improves the workflow adversely affected.

3 · It must be at. Each time warping the individual blocks in F must be taken by hand, which is very time-consuming.

k. The dewatering becomes progressively worse with the enlargement of the blocks, since the water collects at the bottom, while there is a lack of water inside the block.

These deficiencies should be remedied according to the following suggestions:

1. The starting material is a super soft foam of the lowest Volume weight used in plate form. It can be highly compressed for shipping and storage and gets its original volume back in the shortest possible time as soon as the compression pressure through the packaging sleeve will be annulled.

2. The larger blocks are finished with punched out to the Provide matching recesses for the corresponding smaller blocks. The smaller, rooted blocks are therefore warped quickly and with the greatest possible care of the suction roots in the larger block.

3 · A large number of the larger blocks sit on a standardized, pre-cut base plate, which reduces the workload to a minimum.

k · The dewatering is inevitably significantly impeded by adhesive barriers between the individual layers of the panels.

109841/0140

improves · Between the "rafters" the water becomes temporary dammed to form a "water bath", and can thus be better absorbed by the suction roots. This adhesive film is perforated in the middle 7.

5. An additional advantage of the stacked ones Foam layers offer itself in that the individual layers are provided with different, possibly increasing fertilizers during production can do whatever is important to ensure growth is.

6. It is not insignificant that the pre-punched block plates an always constant distance between the center points tiert, while the "hand impression" a very unequal one Image generated. '

The attached illustrations demonstrate the proposed System:

FIG. K shows a planting plate which consists of a plurality of "original cubes el" 1, ^e connected with their corners 4a, each of which has a pre-punched cross slot kb for receiving the cuttings or seeds. The entire planting plate has at least the inside dimension of the "Euro pallet" or a plurality of them. This allows the. Planting can be carried out quickly without any additional handles. The inechan. This has made sowing possible. The individual original cubes

are only removed from the planting plate after the roots have been rooted separated and placed in the planting plate

Hatched zones represent the adhesive areas 5b which are sprayed on with stencils or printed on with pressure rollers. They leave the center of the individual plates free in order to control the water flow towards the center.

This adhesive film consists essentially of a; with Saltpetre neutralized gel made from acrolein polymers, the Has a high water-binding property · In addition, fertilizers can be added to this gel. The frames 2 are placed on this base plate 5 without any gaps and are connected to the base plate by applying slight pressure, the recess 2b is left free for the jUr cube "1" sen

Fig. 6 shows the planting plate 6, which is exactly like the planting plate

5 consists of a base plate 6 - shown on the right - from a plurality of individual plates 3a connected at the corners 6a and the frame shown on the left. The frames 2 and, if necessary, the "original cube 1" are drawn with an f to show that the frames of all sizes are punched from a plate in one operation and in such a way that the corners 6a remain unpunched. After the frame 2 with the original cube 1 has been ejected, the connected plate with the frame 3 can be glued to the base plate 6, which is considerably more labor-saving than gluing the individual frames 2 according to FIG. 5. The gel adhesive layer is only on the edge the base plates 2a and 3a, while the middle 7 of. Adhesive remains free.

Only after rooting through the base plate 3a are the Separate planting plates according to FIG. 6 by plucking off the corners 6a.

The use of the "original cube" 1, which is used in the manufacture of the Accurate frame plate according to Fig. 6, takes place to follow up failures or in small businesses where the Use of. Planting plate according to Fig. 4 is not so urgent is. ''

From Fig. 3 it can be seen that 2 frames 3 are required for each plant cube. This is suggested for economic reasons, since the height of the frame corresponds to 2x the height of the cube according to FIG. Of course, technically you could Make frame 3 from 1 Sifck, but then would not have a twist for the punched out inner parts.

This nesting of one size of cube inside the other can (theoretically) be continued at will:.!, but in the Practice with 3 cube sizes.

Because the individual layers 2c and Jc are separated by a thin gel layer, more or less closed chambers are created in the multilayered cube, in which the irrigation water is dammed and the flow is at least delayed. This gives the plant time for its growth take in a sufficient amount of water and nutrient salts.

The soft foam can be very beneficial with powdered brown or Be interspersed with charcoal, which has a great effect on water retention and growth. ·

While the original dice 1 do not contain any nutrient salts, the Plates for frames and base plates already during production Enriched with optimal amounts of water-soluble nutrient salts be, with appropriate, the advancing needs of the plants in nutrients fct ^ e ^ & ireicherung from 'Stuf e' to Level can be increased.

The plastic substrates that have appeared on the market so far were naturally white or light-colored, which was perceived as annoying and hindering sales. The one with brown or charcoal foamed foam is earth-colored and so comes in color contrary to the wishes of the customers. . . ,, ...

If onion plants are to be grown, Ban can do without the original cube 1 and insert the planting onions directly into the recess 2b of the planting cube 2.

Since flexible foams of low rough weight can be largely compressed without destroying the original volume, can be a variety of planting plates or parts thereof and the "original cube plates" at a low shipping and shipping costs. Storage volumes are packaged for what a consumer big advantage is.
