The present invention relates to a thermal insulation film covering the surface of the seeded field after garlic or onion sowing, and in detail, the bottom film cut in the width direction covering the seeded tofu surface and the space forming film overlaid on the bottom film. The present invention relates to a thermal insulation film for garlic or onion sowing in a double layer which is thermally bonded in the longitudinal direction at the width edge portion of the film.

The purpose of covering the above-mentioned thermal insulation film or conventional single sheet agricultural thermal insulation film with a field sown with garlic or onion is sowing in late autumn so that it is harvested faster than in the spring sowing season. This is a way to get higher profits.

In this seeding method, when garlic or onions are sown in late autumn and covered with a thermal film on the soil surface sown, they are sprouted in early spring, so it is necessary to protect the crops from cold chills during the winter. It can be a food for the tide, thus preventing the damage of the tide and suppressing the growth of various weeds that germinate in the spring, and the fertilizer fertilized in the soil when sowing by the rain or snow in winter or early spring. It can be said to maintain the proper moisture by preventing the loss of the active ingredient and inhibiting the drying of the soil.

The single-sheet polystyrene film, which has been widely used for warming crops for conventional sowing, is sown with garlic or onion in the layered pits between the furrows and furrows of the field, and then covered with the single-layered film, and then the film width is edged. In winter, the shoots germinate by early spring, when the film is covered with soil in the furrows, and when the shoots grow about 2-3 cm, a hole is drilled at the position where the shoots emerge and the stem comes out of the hole. do.

In such a method, a hole of a certain size must be drilled out of a hole in the insulating film that comes in contact with the sprout tip of the sprouts of garlic or onion, and thus the labor cost is higher than the labor cost for sowing. If you don't make a hole at the right time after sprouting, the film sticks to the bottom, causing stems and stems to stick out. Also, it keeps warming with the insulation film during the winter so the germination time is faster than natural germination. When the film is perforated, stems and roots in contact with the atmosphere are subjected to cold damage. However, if the perforations are not performed at the appropriate time, there is a closed point in which the problems described above occur.

As another example of the conventional thermal insulation film, sowing garlic or onion, and then bending the bamboo or elastic plastic bar (flat or rod-shaped) cut into the arch formed between the furrow and the furrow of the field, the both ends of the edge of the toad It is a method of keeping warm by forming a shallow dome tunnel when the film is fixed at regular intervals, and the insulation film is put on it, and the edge of the film width is covered with soil in both furrows to fix the film. It may be advantageous in labor costs because it does not need to be drilled when sprouts appear on the shoots, but there is a high possibility of being damaged by strong winds in winter, especially when the snow is damaged at the support and the film contact part, and once any part is broken, the entire seeded furrow The loss of warmth is accompanied by the risk of cold.

In addition, the contents of the "heat insulation film for garlic or onion sowing" filed as a domestic patent application No. 10-2006-0011044 (application date: 2006.02.06), that is, the buried portion (1A) For forming the space having a hole 2B on both sides and a minute vent hole 2B is formed on the bottom film 1 having numerous holes 113 horizontally and vertically aligned with the seeded portion. The film 2 is heat-bonded at the heat-adhesive part 3, and the space-forming film 2 is adjacent to the inner side of the heat-adhesive part 3 on both sides, and a continuous cutout line 2C is formed in the film length direction and both sides are formed. It is an insulating film for garlic or onion sowing, which is superimposed on a space forming film having an extra width larger than the width of the bottom film 1 inward from the heat adhesive portion 3.

The film is a heat-insulating film that was filed before the patent application by the patent applicant, and used to test the seeding of garlic in the fall of last year, resulting in several defects. The film has excellent thermal insulation after sowing and excellent protection against cold damage after sprouting out of the hole of the bottom film.

First, it is difficult to match the location of the seeded garlic or onion seeds with the holes 113 formed in the bottom film 1 when installing the thermal insulation film, and when the shoots come out, they are not properly matched to the holes, which causes the bottom from the early spring soil. The ratio of shoots not coming out of the film is close to 10 to 20%, and there was a problem that the cut line 2C continuously formed in the longitudinal direction in the space forming film 2 during the winter was easily broken by the strong wind.

Not only can solve the problems caused by the conventional film for garlic or onion sowing, but also the seeds and bottom sown when sowing as a thermal film for garlic or onion sowing that supplements the drawbacks of the above-mentioned domestic patent application No. 10-2006-0011044 It allows the shoots to easily come out on the bottom film during seed germination without the demanding installation work to match the holes formed in the film, and can easily remove the film for forming the upper layer, and also keeps warm in winter and the temperature after sprouting It is an object of the present invention to provide an insulating film for garlic or onion sowing to prevent cold damage until this rise.

The present invention is a double layer consisting of a space-forming film overlaid in the width direction on the bottom film and a thin bottom film that directly touches the tokdo surface as a heat insulating film to cover and fix the seeded soil surface after planting garlic or onion. Specifically, the thermal insulation film will be described in a state in which the bottom film A having a predetermined width of the thermoplastic synthetic resin film and the space forming film B having a larger width than that in the side are matched with each other as shown in FIGS. 1 and 2. Adhesion line (C) is formed by adhering in the longitudinal direction at a distance from the sides, and each of the buried portion (D) is formed on the outside of both bonding lines (C) and the inner bottom film (A) of both bonding lines (C) There are a number of partial incision line (A1) having a certain width in the width direction at the same time the margin portion (A2) is formed on the bottom film (A) surface is attached to the bottom film fixing yarn (A3) of the length in the longitudinal direction And fold Ray film for forming a space between the inner side of (C) (B) may be referred to a number of vent holes (B1) is ttuleojin recess garlic or onion planting insulating film for which (B2) are formed.

Another example of the thermal insulation film according to the present invention is a thermal insulation film replaced with an agricultural light shielding film instead of the bottom film (A) of the thermal insulation film. Here, the agricultural shading film (membrane) is an agricultural shading film such as the bottom film shown in Figure 6 in the shape of the foot stitched together at a predetermined interval in the vertical direction with respect to the film band longitudinal direction in the state in which the narrow film band of the synthetic resin material connected. can do.

The composition of the thermal insulation film according to the present invention using the same is a bottom film (A ') formed by weaving by a plurality of lines of seam (A'12) by connecting a narrow film band (A'11) of the synthetic resin material as shown in FIG. ) And the space-forming film (B) having a width larger than that of the bottom film in the state in which the sides are matched in the longitudinal direction at a predetermined distance from both sides to form an adhesive line (C), A buried portion (D) is formed on the outside, and a bottom film fixing yarn (A'13) is attached to the bottom film (A) surface between the adhesive lines (C), and a vent hole in the space forming film (B). (B1) can be referred to as a thermal insulation film for garlic or onion sowing is formed with a space portion (B2) through which.

Here, the insulation film is produced so that the width between the adhesive line (C) is consistent with the width of the field tack, and the buckled portion (D) is embedded with soil on the slope of the pit and some furrows.

The width of the film between the cut line A1 formed on the bottom film A of the thermal insulation film and another cut line A1 should not exceed 2 cm or more, and the width of the margin A2 should not exceed 2 cm. When it exceeds, the seed germinates and the shoots come out of the bottom film, and the bottom film fixed yarn (A3) is suitable for nylon monofilament or twisted synthetic yarn, and the thickness ranges from 0.5 mm to 1 mm. Alternatively, if the space is adhered with a weak adhesive such as PVA, and the space portion B2 is formed in a rectangular shape from the space forming film B to the film between the two adhesive portions C, a height range of 10 cm to 15 cm is appropriate. The pores B1 are formed in the longitudinal direction within the range of 30 to 50 cm around 2 to 3 mm.

In addition, the width of the film band of the bottom film (A ') using the agricultural light shielding film is around 5mm, the width between the bar line is about 5cm and other components and specifications are the same as the former thermal insulation film.

The method applied to sowing or cultivation of the insulation film as described above is sowing the seeds of garlic or onion (101) on the toad in the field formed with toads and furrows, and then double the adhesive line (C) of the insulation film to the width of the toads After matching the both ends, the two buried parts (D) are in contact with the inclined slope surface, and then buried with soil, and then the film forming the space (B2) is driven to one side and folded, so that the folded portion 102 is in contact with the soil of one buried part. Then cover a little soil and the bottom film fixing yarn (A3) is fixed to the small pile 103 at both ends to be embedded in the soil to prevent the lifting of the bottom film, thereby ending the seeding work as shown in Figure (4) When the early spring shoots are removed, the soil covering the fold 102 is removed.

Once the shoots are pushed up to the incision line (A1) of the bottom film, the shoots push up the film to form the space portion at once, and the space is automatically formed as shown in FIG. 5, the shoots grow and the stems and leaves are formed. At this time, there is a difference depending on the temperature of the season, but when the bottom film fixing yarn (A'13) is pulled toward the adhesive part (C) between 20-30 days after the shoots are formed, the film forming the space part in the adhesive part (C) is cut. It is removed from the bottom film, leaving only the bottom film and the investment part on the floor. The film forming the space portion thus removed is rolled up and used again as a film for floor formation.

The garlic or onion insulation film made as above is double-layered, so it is excellent in heat retention, so that the winter sea of seeds does not occur during the winter, and the perforated line is formed at a narrow interval on the bottom film so that the shoots can be easily placed anywhere. As it can come out of the film, it is possible to reduce labor costs by not having to punch holes in the conventional single film thermal insulation film, and also like the dual film which is picked out during the germination even like the thermal film made of perforated bottom film. Otherwise, not only can it completely prevent the loss of seeds, but even if it meets a cold climate after germination, it can be kept warm for about 1 month by the space formed by the film, which can prevent cold damage. Garlic or onions that can yield and significantly increase yields early It can be referred to persuade insulating film.
