Description

Since the conventional covering material requires a portion to be buried in the soil for fixing, the entire width of the covering material cannot be effectively used on the ground .

If the coating material embedded amount of the soil is insufficient, turned up in the wind, that thing or that would damage seared neighboring crops with a coating material, and out on the road blown in the wind become a traffic hazard, also, if wrapped in wire, power failure it and Do Runado Ru cormorants caused the accident, has become their cause.

In addition, as fixed for the soil, by using the valley and of the adjacent ridge soil, in a case that is doing a multi-product species cultivation, and development disorders that can occur in that mix soil of poor crops of compatibility, There are not a few problems such as increasing the risk of failure such as continuous cropping failure caused by continuous cultivation of the same species.

When embedded in valley soil with adjacent ridges, the covering materials overlap, so the width of the ridges must be widened, such as widening the valley, and wasteful land that cannot be cultivated. There will be many intervals. As a result, the number of culling is restricted and restricted, and the amount of cultivation and the yield are reduced.

As a result, even a coating material of a smaller size than the conventional one can be securely fixed while securing the same volume, so that it can be used safely and safely, thus expanding the range of use. In addition, it is possible to reduce the cost of the covering material.

Wire 3 shown in FIG. 5, may be of single-wire or multi-conductor, preferably, the thickness in the sheath (coating) with a hard Messenger (galvanized steel wire seven twisted line) of about 5.5Sq~38Sq 8Sq ~ 14Sq is more preferable, because it is a wire with moderate elasticity , improving workability and improving airtightness, adhesion and restoration, increasing the reliability of tunnel protection against insects and cold. .

Claims (6)

A covering material that covers cultivated land for insect repellent and heat retention, and when used in a tunnel shape, a weight to prevent the covering material from being lifted by wind etc. on the edge to be grounded and / or Or to attach fixing materials and / or weights that can be installed so that they can be easily opened and closed with the fixing material attached to the edge of the covering, and fixed and held in the closed state. Agricultural covering material characterized by comprising at least one edge of the above means. 2. The covering material according to claim 1, wherein the means is a loop or a cylindrical insertion part. A coating material according to claim 1, fixing material Ru passed through the means of claim 2 and / or a combination of an insertion composed weigh. The inserted article has an appropriate weight for pressing the edge of the covering material, does not expand or contract, is elastic, has a resilience, and has an appropriate flexibility. The combination according to Item 3. The combination according to claim 3 or 4 , wherein the insert is a wire. The cultivated land is covered with a covering material having a strip, a loop provided at an edge of the strip, and an insert such as a wire passed through the loop, the loop is grounded, and the wire is inserted. A method of covering cultivated land for insect protection and heat retention , which is characterized by preventing the edges from being turned up by wind etc. by applying weight and / or tension of the object.
