Abstract

<P>PROBLEM TO BE SOLVED: To provide an insect-proof and cold-proof net convenient not only in agriculture as work, but also in amateur domestic agriculture by chemical-free cultivation. <P>SOLUTION: The agricultural insect-proof and cold-proof net utilizes an agricultural wind-proof net 5 longitudinally and latitudinally woven using monofilament to make a portal arch using artificial bamboo and a glass fiber rod, sticking up a plurality of the arches on a vegetable cultivation bed, hooking the meshes of the agricultural wind-proof net on both ends of a grass rod 3 projecting from the portal arch to form a net tunnel to have insect-proof function; and inserting a polyethylene film into the net tunnel to prevent cold damage when there is risk of frost/snow damage. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  TECHNICAL FIELD The present invention relates to an agricultural insect repellent and cold net for protecting crops from insects, frost, and snow, and more particularly to an agricultural insect repellent and cold net that can be used easily and inexpensively in a kitchen garden.

  Conventionally, agricultural insect repellent nets have been designed to prevent insect damage and not to prevent frost or snow damage.

  The agricultural insect repellent net is formed into a sheet by weaving transparent monofilaments as warps and wefts.

  When using, cover the plants you want to protect from insects. That is, as in the case of tunnel cultivation, a plurality of flexible support posts are arranged in an arch shape and covered with an insect repellent net for agriculture, and the insect repellent net is fixed to the support post using a wire or the like.

  However, since there is no structure for fixing the insect net on the support column, it is necessary to use a wire or a clamp as described above. For example, a hobby use such as a kitchen garden has time allowance. Although possible, it was unsuitable for farmers who lived in agriculture.

Also, special insect repellent nets with a mechanism to fix to the pillars must meet the needs of various customers in terms of their size, and a variety of standard products must be prepared, which is a heavy burden on the distribution process. Become.

  Accordingly, the present invention provides an agricultural insect repellent / cold net that can be used for frost and snow as well as an agricultural insect repellent net that can be conveniently used not only for farming as a farm but also for home garden agriculture.

  The means for that is not to prepare specially prepared nets, but to devise arches by diverting agricultural wind-proof nets that are generally marketed using monofilaments with 5 to 6 mm mesh, which are generally commercially available. I made it.

  Cut the windbreak net for agriculture along the cultivation floor, stand multiple gate-shaped arches on the cultivation floor, pierce both ends of the flexible horizontal bar protruding into the mesh of the windbreak net and integrate it in a tunnel shape Turned into.

  As shown in Fig. 1, the gate-shaped arch is assembled as a vertical column 2 using two artificial bamboos or natural bamboo, and the coupler 4 is inserted into both ends of the horizontal bar 3, and the ends of the horizontal bar are coupled to each other. More than a few centimeters, and a combination of the vertical axis of the coupler and the inner diameter of the pipe of the vertical column.

  Stand up several completed gate-shaped arches on the cultivation floor, and evenly cover them with a windbreak net that has been cut according to the length of the cultivation floor, and place one protrusion of the protruding horizontal bar on the mesh. Insert.

Next, stab the opposite protrusion that is not inserted into the mesh, but if the horizontal bar is slightly bent or if the mesh is pulled and replaced inside the 3-5 mesh, the mesh will be tightened and integrated with the wind Become.

The slack in the length direction of the cultivation floor is adjusted by changing the position where the vertical pillar stands.

  FIG. 2 is an enlarged view of the coupler 4, and there are two types, 41 and 42, as shown in the figure. 41 uses a commercially available split pin, and a sleeve is fitted so as to be inserted through a hole of a pipe of a vertical column.

  The inner diameter of the ring of the split pin is prepared so that it can be inserted in advance using a drill slightly larger than the outer diameter of a horizontal bar (for example, a glass fiber rod having a diameter of 4 mm).

  Reference numeral 42 denotes a case where the coupler is mass-produced, showing an example of a plastic molded product, 42a being a side view thereof, and 42b being a front view thereof.

FIG. 3 is a perspective view representing an image of an agrochemical-free vegetable cultivation floor in which the agricultural insect-proof and cold-proof net of the present invention is installed.

  General agricultural windbreak nets have good light transmission and protect the vegetable growing group from the wind. The structure is strong against wind and rain and does not block sunlight. It is possible to grasp the growth status of vegetables and to manage watering easily.

Since the agricultural insect repellent and cold protection net according to the present invention has a simple structure as described above, if only a vertical column and a horizontal rod made of glass fiber and a coupler are purchased, it can be easily applied to any size, Can be stretched for many years.

  When managing vegetables, remove only the net temporarily to complete the entire work, and perform small work by partially rolling up the bottom of the net.

The function as a cold protection net of the present invention protects vegetables from frost and snowfall by temporarily spreading and wearing a plurality of used polyethylene or vinyl sheets on the vegetables covered with the windproof net.

Pesticide-free vegetable cultivation requires labor and time to eliminate insects with chopsticks and tweezers or to eliminate insects with the help of EM bacteria, so it was necessary to increase the selling price, but this invention If it becomes popular, it will be possible to sell it at almost the same price as agrochemical-use vegetables, and its economic effect is immeasurable.

If cultivation of pesticide-free vegetables can be done easily, medical expenses for pests, animal genital dysfunction, malformation, etc., which are harmful to pesticides in animals including humans, will be reduced, and deaths from cancer will be drastically reduced and You will be able to live longer.

Part of the global pollution caused by the spraying of pesticides will be stopped.

  When a windbreak net with a width of 2m is used, it is best to use a 1m long horizontal bar. The gap between the portal arch and the arch is about 1 meter. The frame is enough.

  Windproof nets are commercially available and can be selected in widths of 1m, 2m, and 4m. Lengths can be selected in units of 20m and 100m, but they are also sold in meters.

  If you dispose of used windbreak nets carefully, it may become a causative substance of environmental hormones, so the warning will be highlighted in the instruction manual, and disposal should always be done in a local high-temperature melting furnace. It is necessary to choose a path that will be a source of thermal power generation or a heat source for the hot water pool.

  From the viewpoint of suppressing global warming, it is most ideal to dispose of naphtha and improve the recovery mechanism, but there is no choice but to wait for the further spread of the present invention.

The portal arch which is an important element of this invention is shown. An enlarged view of the coupler is shown. Perspective view of cultivation floor with insect repellent net, A vegetable grows on the cultivation floor and shows a white butterfly dancing outside the net.
