Description

[Detailed explanation of the invention] [Purpose of the invention] Industrial field of use...This invention is used to coat plants in the growing process from seeds and seedlings to keep them cool and This invention relates to improvements in plant growth sheets used for heat retention, weed control, and prevention of pests and diseases.

Conventional technology: Conventionally, for the purpose of protecting seeds and seedlings, covering plants in the growing process from seeds and seedlings to keep them cool, keep them warm, suppress weeds, prevent pests and diseases, and prevent transpiration. Straw was used, but it was easy to tie up and the work was complicated, so in recent years it has been called mulch film, which is a soft synthetic resin film with many round holes. The seedlings that had grown from the seedlings were covered with the film, or a plurality of films without round holes were used to form gaps. The above two methods achieve the objectives of keeping cool in the summer, keeping warm in the winter, suppressing weeds, and preventing pests, but on the other hand, they deteriorate and become brittle as time passes.
Not only could it not withstand long days, but it also had the disadvantage of poor ventilation, which caused plants to slough, and the disadvantage that fertilizer and water did not penetrate uniformly into the soil.

Recently, a screen-like sheet for growing plants has appeared, which is made by knitting flexible belt-like bodies made of soft synthetic resin such as polyethylene into a screen-like screen using braided cords. This blind-shaped plant growth sheet does not deteriorate or become brittle over time, and it also allows fertilizer and water to be evenly distributed and watered, retains coolness, retains heat, and suppresses weeds.
The purpose of preventing pest damage and transpiration is achieved, but
Incidentally, in the process of plant growth, the upward growth of the plants is inhibited by the covering sheet, resulting in a drawback that sufficient plant growth cannot be obtained.

Problems to be solved by the invention: The invention is unlikely to deteriorate or become brittle after use for a number of days, and is breathable, allowing fertilizer and water to be applied to the soil without causing stuffiness to the plants covered with the invention. can be uniformly sprayed and watered, and not only can it sufficiently achieve the purposes of cooling and heat preservation, weed suppression, pest and disease prevention, and transpiration prevention, but also can maintain sufficient plant growth without inhibiting the upward growth of plants. The object of the present invention is to obtain a sheet for growing plants that can achieve the above-mentioned purpose by being suitable for growing plants even in cold regions and tropical regions.

[Structure of the idea]

Means for solving the problem... In order to achieve the above-mentioned purpose, the present invention provides a sheet made of flexible and deterioration-resistant strips knitted in a blind shape with braided cords, in which two upper and lower strips are polymerized. One of the sheets is silver in color and the other is black, and the plant growth sheet has a narrow portion and a wide portion formed between the braided wires.

Next, an embodiment of the above configuration shown in the drawings will be described as follows.

As shown in FIGS. 1 and 2, a large number of belt-shaped bodies 11, 11,
11, 11', and 11' are formed by stacking two sheets one above the other. The upper band 11 is silver in color, and the lower band 11 is black.

The above-mentioned strips are arranged in parallel and are knitted together to form a plurality of rows of braided wires 12, 12, 12, . . . to form a sheet 20 knitted in a blind shape. At this time, in the present invention, the braided wires 12, 12 are not spaced at equal intervals, but a narrow portion 13 and a wide portion 14 are provided between the braided wires 12, 12. The braiding method using the braided cord is to form the braided wire 12 using a known method such as hand weaving, karami weaving, or lattice weaving.

The distance between the wide portion 14 and the next wide portion 14 is
Seed sowing lines are sown linearly in the field at regular intervals, and are formed at intervals 1 equal to the aforementioned regular intervals.

Function: The sheet 20 is placed over the seeds in the field so that the wide portion 14 of the plant growth sheet of the present invention constructed as described above is positioned above the seed sowing line in the field. As shown in Figure 3, during the growth of seeds and seedlings, temperature rises and falls are prevented,
It suppresses the emergence and growth of weeds, prevents damage caused by pests, and prevents evaporation of moisture in the soil. But sheet 2
0, and the seeds and
To hold seedlings without sagging and evenly infiltrate fertilizer and water into the soil. When the plant eventually grows and grows upwards, the wide portions 14 of the strips 11 and 11' are sewn together as shown in FIG. 3, allowing the plant to freely grow upwards through the gap. I can do it. In addition, in the present invention, two upper and lower strips 11 and 11' are used, one of which is silver colored and the other black, so when using the silver strip 11 on the top, the silver strip 11 is placed from above. The lower black strip 11' reflects solar heat, and the lower black strip 11' absorbs geothermal heat.If used upside down, the upper black strip 11' absorbs solar heat and retains heat, and the lower silver strip 11'
can reflect geothermal heat and prevent it from dissipating to the outside.

〔effect〕

The present invention has a structure in which narrow parts and wide parts are alternately formed between the braided wires in a sheet made by knitting flexible and deterioration-resistant strips into a blind shape using braided strings. Therefore, it is less likely to deteriorate or become brittle after being used for a number of days, and it is breathable. Fertilizer and water can be uniformly sprinkled and sprinkled without causing stuffiness on the plants covered with this invention, and it can also be kept cool, warm, etc. Not only can the objectives of suppressing weeds, pests and diseases, and preventing evaporation of water in the soil be fully achieved, but also it is sufficient to simply cover the field with the sheet 20, and no other effort is required. Furthermore,
Not only is it possible to obtain a plant growth sheet that allows sufficient plant growth without inhibiting the upward growth of plants, but also the sheet formed by knitting the band-like bodies in the form of a blind with braided strings according to the present invention. The above-mentioned belt-shaped body is composed of two upper and lower layers, one of which is silver colored and the other black, so it can be used upside down not only in temperate regions but also in cold regions and tropical regions. By doing so, the above effects can be achieved.
