Abstract

To solve the problems in which: in a cultivation method using a winterizing tunnel, an edge of the tunnel covering material is rolled up for temperature adjustment in the tunnel, so that the covering material is kept down from the upper side to be fixed while tunnel pillars, rubber strings or the like weave zigzag on the covering material; therefore, the intervals between tunnel pillars should be kept narrow for installation so that a lot of tunnel pillars must be used and huge cost to purchase materials and a large amount of labor for installation and the like are required; and an agricultural covering material and a method thereof are required to provide capable of using with less labor of opening/closing and installation/removal.SOLUTION: A covering material 1 and an installation method are given having insertion parts 2, 3 in which an inserting object 4 and the like are inserted into an existing band body and fixed to pillars by use of bindings or the like at both ends to enable fixation of the whole covering material 1, easy opening/closing at the time of installation, control and the like.SELECTED DRAWING: Figure 8

Description

The present invention relates to a covering material such as a sheet and a net for covering cultivated land such as a field ridge.

As a construction method for fixing with a tunnel covering material, especially using a heat insulation (cold protection) sheet, conventionally, a zigzag covering is applied to the covering material covered with a string-like object such as rubber or rope on the pillar. It was fixed by stitching it on, or a tunnel support was used, and the covering was fixed by a support so that it was pinched from above the tunnel covered with the covering.

If the cultivation method using the heat insulation tunnel covering material is constantly closed, the temperature and the like in the tunnel rises excessively, which adversely affects the cultivated crops. Therefore, in order to prevent the temperature inside the tunnel from rising too much, the bottom of the tunnel must be turned up, ventilation must be performed, and the temperature and humidity must be adjusted. Therefore, like the insect-proof tunnel, it is not possible to dig the soil in the valley and fix the edge by embedding it in the soil, and to adjust the temperature and humidity, you can open and close it using a string-shaped object or a tunnel post to cover it. It is fixed.

When fixing with a string-shaped rubber belt, etc., you must hang the belt on the hooks on the valleys on both sides of the tunnel and press the covering material with the belt so as to sew in zigzag right and left on the tunnel-shaped covering material. Not only is it difficult to fix by yourself, but since the covering material is pressed down and fixed by the string-shaped belt, the tunnel shape cannot be maintained unless the tunnel pillar spacing is set narrow, and it is turned up. Since it becomes impossible to fix the covering material when it is used, it is necessary to install many tunnel posts at narrow intervals.

The hook for hanging the rubber belt etc. on the hook of the valley must be installed and fixed by hitting it on the ground, and it must be installed firmly so that it will not be pulled out by the hooked belt. In addition, since hooks such as pegs need to be installed on the left and right of the ridge between each of the tunnel stanchions, it requires about twice the number of tunnel stanchions and requires a lot of materials and labor. To do.

In the case of fixing with a tunnel support, the tunnel support is erected by straddling the ridges, covering it with a covering material, and then between the support pillar under the covering material and the support pillar, from above the covering material with another tunnel support pillar. Fix the covering material by pinching and pressing it. In this case, the required number (number) of tunnel pillars is almost twice as many as the pillars that support the covering material. Therefore, the initial purchase cost of the tunnel support is about twice as much as when fixing it with a belt.

When fixing the covering material by fixing it with a tunnel support or a string belt, etc., if the tunnel support is not installed at a narrow interval, the tunnel shape can not be maintained, temperature and humidity. Because of the adjustment, it becomes difficult to fix the covering material when opening and closing the sock, so it is necessary to install many tunnel posts at narrow intervals. Therefore, not only the required number of tunnel pillars and labor for installation are inevitably increased, but also a lot of labor and space are required for cleaning, transportation and storage after use.

Hands are put in the tunnel for work such as topdressing, thinning, weeding, etc. However, since there are tunnel struts etc. at a narrow interval, the tunnel struts etc. will be an obstacle and a wide range of work can not be done at once, so it is frequent Because it is necessary to put in and take out hands, not only is it painful both physically and mentally, but work efficiency is reduced.

When digging a valley and embedding and fixing the edge in the soil, it is possible to work alone, and the required number of tunnel pillars may be small, so the labor of installing the tunnel pillars is reduced, and the cost of purchasing pillars and using them It does not require much cleaning work and storage space afterwards, but it is fixed by digging around the ridge, covering it with a covering material, and pressing the edge with soil, so you can flip the edge to adjust the temperature and humidity. For example, since there is no fixed part, when the wind blows, the covering material is blown by the wind and cannot maintain its shape.

The present invention made in order to solve the above problems, except for the edge of the strip, is an agricultural coating material having an insertion portion provided in the strip, the strip-shaped coating material is preferably a sheet resin. Or, it may be a non-woven fabric or a woven fabric, or a covering material made of a net or the like, or a composite material thereof.

Since it is not necessary to fix the tunnel covering material such as a heat insulating sheet with a string-like object such as a rubber belt by pressing it from above the covering material like zigzag stitching, install a hook etc. to hook the string-like object. No need. Therefore, not only is the labor unnecessary, but the tunnel shape can be maintained even when the spacing between the tunnel columns is wide and the number is small.

Since it is not necessary to press the tunnel covering material such as a heat insulation sheet into the tunnel pillar and press it from above the covering material to fix it, the required number of tunnel pillars can be reduced even if the supporting tunnel pillars are installed at the same narrow intervals as before. It can be significantly reduced to about half.

Since the required materials and quantity of tunnel pillars are small, the labor required for installing them and the material purchase cost can be reduced. In addition, since the absolute number of tunnel columns used can be small, the labor and storage space for installation, transportation after use, cleaning after use, and the like can be reduced.

If the supporting pillars are installed at the same pitch as the conventional ones, the pillars used to fix the covering material and the string-like object do not exist, so the distance between the pillars is approximately doubled. For this reason, it is possible to perform a wide range of work at a time without being an obstacle to work such as adding fertilizer or thinning out by putting a hand in the tunnel.

Even if the skirt of the covering material is flipped up to adjust the temperature and humidity, the entire covering material is fixed by fixing the inserts (wires etc.) that have passed through the insertion part at the center side to the piles at both ends of the tunnel. Therefore, not only can ventilation be performed without breaking the tunnel shape, but the insertion part on the edge side can not only fix the foot, but it is not possible if it is fixed with a pillar or a string-like object. It was possible to open and close the existing work.

By fixing to the pile at both ends of the tunnel, the entire tunnel covering can be fixed, so the distance between the tunnel columns is wider than before and the tunnel shape can be maintained even when there are few tunnel pillars. Even if you put your hands into top fertilization, thinning, weeding, etc., since there are few tunnel posts, it will not be a hindrance, there will be no pain, and you can perform a wide range of work once without interruption.

In the installation of the covering material, if the insertion object (wire or the like) passed through the insertion portion is firmly fixed to the piles at both ends of the ridge with binding wires or binding bands, the entire covering material is fixed. Therefore, the conventional method requires heavy labor and a lot of materials, so that it can be used easily by many people who have refrained from using it or by many people.

If strong winds are expected and reinforcement fixing is required, you can easily perform reinforcement fixing by pressing the insert on the edge side to the ground with pegs, etc., so that it is exposed to cold air etc. In that case, the covering material may be unstable such as being blown off, but it can be used continuously without becoming unstable, and the crop can be covered without being defenseless and can be used stably. Can.

Since the entire tunnel covering material can be fixed with the piles at both ends of the tunnel, it is possible to fix and use each of the plural covering materials individually at once. Therefore, for example, in the case of crops cultivated from autumn to spring, insect control and cold protection are required, but these can be used alone or at the same time when necessary, and they will not be replaced and will be interrupted because of stacking. It becomes possible to cover without. In addition, it is possible to use a light-shielding or growing color sheet or the like on the insect-proof or cold-preventing covering material only when necessary.

Since the insertion part intersects with the support, the insert and the support passed through it can be easily bundled and fixed, so that the covering material can be fixed more firmly, but only the insertion part is cut. Since the coating is performed, the coating is not damaged and can be kept intact, and the function of the coating is not impaired.

Two insertion parts 2 and three insertion parts 3 are provided on the center side and the edge side along a strip-shaped shape (longitudinal direction) of a covering material such as a heat insulation sheet for tunnel cultivation or a net, as shown in FIGS. 1 and 2. I have it.

The strip-shaped (longitudinal direction) length of the covering material shown in FIG. 1 is 0.5 m or more and about 300 m, and the width is about 0.5 m to 6 m, but it is generally about 1.8 m. is there.

The insert (wire) 4 is passed through the insertion part 2 and the insertion part 3 shown in FIG. 2, the piles 8 are firmly driven into both ends of the ridge 9 shown in FIG. 5, and the insert (wire) 4 is pulled and fixed to it. The ends of the covering material 1 are bundled and fixed to the pile 8 with a binding band or a binding wire. As a result, it became possible to fix the entire tunnel of the covering material 1. At that time, as shown in FIGS. 4 and 5, airtightness is ensured by closely adhering to the soil of the ridges and valleys.

FIG. 4 is a front view (cross-sectional view) of the embodiment. The insert (wire) 4 shown in FIG. 4 may be a single wire or a multi-core wire, but preferably a hard messenger with a sheath (coating) (7 galvanized steel wires) and a thickness of 5.5 Sq. Although it is sufficient to use a wire of about 38Sq, 8Sq to 14Sq is more preferable, and since it is a wire that has tensile strength and appropriate elasticity, it is possible to obtain improved workability and airtightness/adhesiveness and restorability. Increased confidence in insect protection and cold protection.

In the usage example of FIG. 4, the insert (wire) 4 is used, but instead of this, a pipe or the like may be used instead.

The tunnel post 6 shown in FIG. 5 is made of bamboo or the like, or is commercially available, and the material thereof may be metal, wood, resin, or any other fibrous material and may be easily used. Further, the pillars are erected at intervals of about 0.5 to 2 meters so as to straddle the ridges, and the covering material 1 of the present invention is placed thereon so as to cover the tunnel pillars 6. This work is almost the same as the conventional product of the existing technology, but as shown in FIG. 6, conventionally, the covering material was fixed so as to be pressed by the tunnel support 7 from above the covering material 1. However, according to the present invention, as shown in FIG. 5, without using the fixing tunnel support 7 shown in FIG. 6, the insertion member 4 passed through the insertion portion 2 and the insertion portion 3 shown in FIG. Not only is it possible to maintain the airtightness and tunnel shape equal to or better than the fixing method using the conventional tunnel support 7 shown in, but in addition, the labor and time required to open and close the covering material are Compared with the method, it is not too many, and the covering material can be opened and closed easily in a very short time. Therefore, it is very effective not only at the time of harvesting but also when managing weeds, topdressing and thinning.

Conventionally, as shown in FIG. 6, the covering material 1 is fixed so as to be pressed by the tunnel support 7. Therefore, in order to work inside the tunnel, it is necessary to lift up the skirt of the covering material 1 and put a hand through the narrow gap between the tunnel support 6 and the tunnel support 7, which naturally limits the work range. Although these columns hinder the work, the present invention does not have the fixing tunnel column 7 shown in FIG. 6 as shown in FIG. Therefore, even if the pillars are installed at the same intervals as the tunnel pillars 6 shown in FIG. 6, the space between the pillars is doubled, and a wide range of work is possible, but as shown in FIG. The spacing can be made wider than that of the conventional pillar support 6 shown in FIG. 6, and the required number of tunnel support 6 can be reduced.

When the soil in the cultivated area has unevenness and is difficult to adhere to, or when the edge of the covering material 1 is lifted by the wind, a peg such as the peg 10 shown in FIG. The insert 4 is pressed and fixed. As a result, the covering material 1 is pressed and fixed by the fixing tunnel support 7 shown in FIG. 6, but since it is not provided, the capacity in the tunnel is not reduced as shown in FIG. In addition, since it becomes strong against wind and the covering material is not easily peeled off due to wind, it is possible to prevent crops from being exposed unprotected and protect crops from pests and cold. In addition, the covering material blown by the wind can be used to prevent damage to neighboring crops and other accidents caused by flying around.

FIG. 3 is a front view in which the insertion part 3 shown in FIG. 2 is removed and only the insertion part 2 is provided. As shown in FIG. 3, the insertion part 2 is provided, but one insertion part is provided on the center line. It is very good to increase the number of three, and the insertion part 2 on the center line may be left and the insertion part 2 may be removed to provide only one. Further, like the insertion portion 13 of FIG. 10, it may be provided between the insertion portion 2 and the insertion portion 3, and the insertion portion 13 may be provided with an appropriate position and quantity depending on the size of the covering material and the intended use. ..

FIG. 6 is a side view of a general use example of a covering material for cold weather until the present invention is made.
As shown in FIG. 6, although the tunnel struts 6 and the tunnel struts 7 are lined up at a narrow interval, they are necessary for maintaining the tunnel shape and fixing the covering material 1. Therefore, when performing work such as topdressing and thinning, it is necessary to insert a hand through the space between the columns, and work in a wide range becomes impossible.

As shown in FIG. 7, if a part of the insertion portion 2 is cut, it becomes possible to pass the tunnel support 6 between the insertion object 4 and the covering material 1. As a result, the tunnel support 6 and the covering material 1 are integrated by the insert 4, so that even if the tunnel covering of the long ridge is performed or the edges of the covering material are turned up and the work is performed, the tunnel The shape and the covering material 1 are more stable, the distance between the tunnel support columns 6 can be increased, and the required number of tunnel support columns 6 is reduced.

FIG. 8 is a front view of a use example in which a plurality of coating materials 1 are used at the same time, and each coating material 1 is as shown in FIGS. 1 and 2. However, it is not necessary for each coating material to have the same function, and it is possible to use coating materials having different functions, which is desirable, for example, by installing insect repellent nets and cold protection sheets in layers and cooling them. If there is any, a covering material such as a cold-proof sheet or a light-shielding or growing color sheet can be used.

The insertion part 11 and the insertion part 12 of FIG. 9 are not continuous like the insertion part 2 and the insertion part 3 of FIG. 1, but are functionally the same, and the insertion part 11 and the insertion part 12 of FIG. The insertion part has an intermittent structure. Therefore, the insert 4 passed through each insert may be the same as the insert 4 shown in FIG.

In many cases, the conventional dressing material was difficult to work by one person. Moreover, even if the wind blows even a little, the difficulty is further increased. Since it is used through objects, its elasticity and weight allow one person to cover.

In the covering material of FIG. 1, four insertion parts (insertion part 2 and insertion part 3) are provided, but the insertion part may be one, and the insertion part 2 and insertion part of FIG. 3, four or more like the insertion part 13 may be used.

In the covering material of FIG. 2, the insertion object (wire) 4 is passed through the insertion portion 2 and the insertion portion 3. However, the insertion object 4 may be directly attached to the insertion member 3 without using the insertion object. ..
