Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a method and device for protecting plants.

[Conventional technology]

Plants grown in the ground or in pots, especially in the early stages of growth,
Must be protected from weeds. Also, potted plants need to be protected throughout their entire lifespan.

It is known to cover the ground around young plants with sheet materials such as plastics to protect them from weed infestation. An example of this type of product is disclosed in U.S. Pat. No. 3,955,319.

Light-blocking and water-permeable fabrics have recently been developed that are suitable for use as sheaths to inhibit weed growth.

U.S. Patent No. 3,839,139 No. 4,047,32
No. 7 discloses an example of the sheet.

It is an object of the present invention to provide a method and apparatus for plant protection using currently available sheet materials of the type 1-.

Further objects and advantages of the invention will become apparent from the following description with reference to examples.

[Structure of the invention]

According to the invention, there is provided a method for protecting plants from the growth of weeds in conditions where the artificial soil and mixture thereof on which the plants are planted can breathe and/or absorb liquids. There is provided a method comprising placing a substantially light-impermeable and liquid-permeable shield on the soil/artificial soil and mixtures thereof at the base of the plant.

According to another feature of the invention, the soil in which the plants are planted;
A device for protecting plants from the growth of weeds in conditions where the artificial soil and its mixture can breathe and/or absorb liquid, comprising a seal 1 with an opening for the stem of the plant. , an apparatus is provided in which the shield is opaque to light but transparent to liquid.

According to another feature of the invention, the shield is provided with a slit outwardly from said opening to the edge.

According to another feature of the invention, the aperture is comprised of a plurality of radially extending slits.

According to another feature of the invention, the shield is substantially circular.

According to another feature of the invention, the shield is substantially square or rectangular.

According to another feature of the invention, the circular shield is provided with a circumferential flap, and the edges of the slits extending radially from the opening are shaped to overlap when the shield is used for protecting potted plants. The degree of overlap is determined by the dimensions of the pot, and the shape is such that the shield body and flap fit lightly over the topsoil of the pot and a portion of the sides of the pot.

〔Example〕

According to the invention there is obtained, as shown in the accompanying drawings, a device indicated by arrow 1 for enabling the ground on which plants are planted to breathe and/or absorb liquids and for protecting plants from the growth of weeds. .

The device includes a shield 2 having an aperture generally indicated by arrow 3, which is opaque to light and permeable to liquids.

U.S. Patent No. 3,839,139, No. 4,047°32
No. 7 discloses examples of suitable materials.

Each shield 2 is provided with a slit 4 extending outwardly from said opening 3 to the edge of the shield.

The hole 3 may be a single opening (not shown), but may alternatively consist of a plurality of outwardly extending slits 6.

In the illustrated embodiment, the shield is square or circular, but the outer circumferential shape of the shield may be any shape depending on the situation.

In FIG. 1 the shield is substantially square and in FIG. 2 the shield is substantially circular. In the embodiment shown in Figure 3, the shield is circular and is provided with a peripheral flap 7, which shape prevents the edges of the slits 4 in the shield from forming when the shield is used to protect potted plants. The extent of this overlap is determined by the dimensions of the pot, and its shape is such that the shield body and flap overlap the topsoil of the pot and part of the sides of the pot. It is designed to fit lightly on top. Overlapping edges are stapled or secured.

FIG. 5 of the accompanying drawings shows the use of a square device according to the invention on a ground 9 on which a large plant 11 is planted. This device can also be made circular as shown by the dashed line in the figure. The edges of the slits 4 in this example do not overlap.

In use, the device of the present invention is substantially impermeable to light, although liquids can pass through the shield and penetrate into the ground or artificial soil and mixtures thereof.

The preferred material for constructing the device of the present invention is spindle bonded polyester fabric (S B P F), although other materials may be used as long as they are transparent to liquids and opaque to light.

In the context of potted plants herein, pot shall include any ceramic, plastic or other pot or container bag currently commonly used to protect the plant in a pot bag (e.g. polyethylene). When using the shield, the flap 7 can be fixed to the bag. If the pot is made of a material such as plastic or ceramic, an adhesive may be applied to the underside of the flap 7 so that it can be bonded to the pot.

The edges of hole 3 can be grouped and tied or secured (not shown) around the plant stem.

Although the features of the present invention have been described above with reference only to embodiments, it is of course possible to make changes in design without departing from the scope of the claims.
