FR2746579A1 - Mulching mat for trees, shrubs or plants - Google Patents

Abstract

The mat, designed to protect plants from evaporation and suppress weeds, has a central aperture (8) and a slit (7) from the aperture to one edge, lined with flexible vanes (6, 8). Preferably the mat is made from sandwich layers, of PVC film and bubble PVC, and can incorporate a biodegradable layer of a fertiliser. It can be made in a variety of shapes, such as rectangular, round or hexagonal, and it can be held down by weights. It can be used under fruit trees such as olives and plums to protect the fruit that drops during harvesting.

Description

STRAWING TYPE SLATS / SANDWICH
The present invention relates to protective films or plates of PVC type (or of any other composition according to the cultivation process and the aim to be obtained) for the so-called open-air cultivation of vegetables, seeds, flowers, fruits and correspond to traditional formats. of the current distribution, but while having the possibility of tailor-made for both the shapes and the dimensions, the colors.

The very principle of mulching soil with PVC films is not new in itself, in its current form .11 is mainly used by amateur gardeners, professionals, horticulturalists, market gardeners, to plant by perforating the said PVC sheet. Then then transplant the seedlings or cuttings, and thus protect them from weeds.

avoid evaporation of the water contained in the basement and keep products clean.

it is quite possible or even recommended to introduce straw or flax under the films which, being biodegradable, are very good natural fertilizers
The invention of the slat and / or sandwich type is characterized in that the standard or made-to-measure sheets are precut lengthwise on the one hand, and also precut but perpendicular to the central slot in floating slats on the other hand . A firm heel but cut to a defined length, allows the whole to be maintained during installation or removal.

The sandwich type also adds a glued or welded coating, formed of bubbles of different diameters. This set having undergone the same precuts as the basic PVC film.

The plate type made of compressed cardboard or thin peat sheets is biodegradable. It has a passage articulated by pre-cut, or with pre-cut strips and serves as protection and fertilizer for small shrubs, fixing by round twisted concrete.

It is worth considering the originality of the system which allows: 1 / the recovery of simple films or with bubbles after the maturity of the plantations 2 / the possibilities of additional uses compared to current systems.

 ex: we can thanks to the central slit and the perpendicular slats draw a furrow, and start an exploitation of the seed and not transplant seedlings. (saving time since only one operation, gaining yield since we no longer have to undergo an always delicate resumption of sowing.) 3 / use, even in the vineyards, or even more in the orchards around the trees thanks to the conical pre-cuts of the lamellae.

4 / increase by natural drilling the production without fertilizer, but thanks to the sandwich type which stores the heat of the day in its bubbles and returns it partly to the ground during the night.

5 / the water and the sun penetrate better at the base of the plants thanks to the spacing created by the natural lifting of the lamellae.

6 / we can also start the cultivation earlier in the predilection season of the different plantations thanks to the presence of bubbles protecting the seedlings, but also later in the season.

 7 / flowers, vegetables are no longer tightened by the collar, pushing without constraint.

8 / in the case of collection by gaulage such as olives, prunes, walnuts, mulching with large bubbles avoids the laying and use of nets. Annexed drawings illustrate the invention.

Figure 1 shows the film unrolled with the central slot (2) the perpendicular lamellae (3), the non-cut part (4).

Figure 2 shows the lamellae raised (5) by the natural growth of plants.

FIG. 3 represents the mulching for trees with straight strips (6), conical strips (8), central slot (7), the uncut fixed part (9).

Figure 4 shows the single sheet coated with its bubble film (10).

FIG. 5 represents the lifting of the slats under the push of the seedlings and the attraction of the sun.

FIG. 6 represents the round cardboard plate with its central hole (11), the partial precut serving as articulation (12), the total precut (13), the fixing by round tor-concrete (14).

FIG. 7 represents the hexagonal cardboard plate with its central hole (15), the partial precut serving as articulation (16), the total precut (- 17), the fixing by tor-concrete round (18).

For FIGS. 6 and 7, the embodiment can also be of the simple PVC type with floating lamellae or of the sandwih type.
Examples of uses: 1 / planting
Cover the surface prepared for planting with a single sheet or sandwich type. Fix the sheet, either with earth on the sides or by bent concrete round tor Trace the groove using a peg following the central slot. Sow the seeds, the strips moved by the pick will resume their place by themselves, trace their elasticity 2 / transplanting / cutting
Proceed in the same way but instead of drawing a furrow, form a conical hole (suitable for receiving the seed piece) with a dibber, also the displaced slats will resume their place according to themselves. Fixing by earth or by round bent tor-concrete.

3 / tree / collection
Return the PVC sheet through the central slot to the center of the cut, join the strips, fix to the ground.

11 shrub protection
After planting the shrubs lift the precut insert the plate to its center, fold the precut, fix by bent round-concrete, the plate to the ground.
