Description

Device and method of the inhibiting growth of weeds that mimics the competition structure of trees

The present invention relates to a weed growth suppression apparatus and method, and more particularly, to a weed growth suppression apparatus and method that mimics a tree competition structure.

Rice accounts for a large portion of Korea's food resources. Rice is a fruit harvested from rice, a crop grown in paddy fields, and it is important to increase its yield. However, the cultivation area of rice cannot increase infinitely. Therefore, in order to obtain the maximum harvest from the paddy field, it is necessary to solve the problem of weeds that impedes the growth of rice.

In the past, weeds grown in rice fields were inhibited by the use of biochemical removers.

Alternatively, weeds were injected into the rice paddies to prevent the weeds from getting enough light. Sun protection is a composition of water and an adjuvant that inhibits the transmission of light. However, the adjuvant naturally does not sink to the soil layer over time, and the composition is very short in preventing sunlight from penetrating. When it rains or receives new injections, the concentration of the composition becomes uneven, which greatly reduces its efficiency.

Drawing.

An apparatus and method for inhibiting weed growth mimicking a tree competition structure according to an embodiment of the present invention is to reduce damage of rice farming caused by weeds growing in paddy fields, and ecologically and naturally inhibits the growth of weeds. The present invention relates to a method for blocking the source of growth inhibition.

In the forests, trees have evolved to increase their height and expand the area covered by branches to monopolize resources such as solar and water resources. Umbrella-like trees essentially block the growth of competitors (competitors) that grow under them by monopolizing the sun's energy over that area. Newly sprouted trees beneath large trees are not grown well and are culled without sufficient sunlight.

The present embodiment is characterized by suppressing the growth by ecologically inhibiting weeds growing in the rice paddies by mimicking the competition structure between the trees.

Referring to FIG. 1, in the case of the rice paddy 1 in which seedlings are completed, the paddy water 5 is filled to grow rice. By dispersing a plurality of small floats 110 in the form of chips in the paddy field 5, daylight does not penetrate naturally into a space (a paddy field) except where rice is planted.

The weed growth suppression apparatus 100 mimicking the tree competition structure according to the present embodiment is a sunscreen float, and includes a plurality of chip floats 110.

The chip float 110 may have a thin chip shape having a predetermined thickness. The shape may be round or oval. It may be implemented in various materials such as paper, plastic, wood, and the like. For wood materials, wood types with less resin (oil) can be used.

In addition, the chip float 110 is to block the input of sunlight, it may be made opaque.

The chip float 110 may be introduced into the paddy and dispersed after the seeding is completed. Since it is possible to block even the space to be planted before seeding, it is necessary to fill the remaining space of the discussion while the seeding is secured.

In dispersing the chip suspended solids 110 into the paddy field, a drone may be used as an input device. A drone may be used to drop and disperse a predetermined quantity of chip floats 110 at key points of discussion. Alternatively, a specially developed robot may be used to spread an appropriate amount of chip floats 110 at key points of discussion.

Referring to FIG. 4, the main point of discussion may be the points P11 to P34 where the partition lines meet after dividing the rice field 1 into M and N equal parts in the horizontal and vertical directions, respectively (M. N is a natural number).

At this time, in the case of the points (P22, P23) surrounded by four other main points in all four of the main points, the quantity of the chip suspended solids 110 injected into a point surrounded by three main points ( In the case of P12, P13, P21, P24, P32, and P33, the quantity of the chip float 110 can be 4K / 3. In addition, in the case of the points (P11, P14, P31, P34) that meets the two main points in the periphery, the quantity of the chip float 110 may be 4K / 2. Although not shown in the drawing, in the case of a point where one main point meets around, the quantity of the chip float 110 may be 4K.

This is to allow even distribution of chips so that the quantity of chip floats 110 at any point in the paddy field 1 may be similar by setting the input quantity differently in consideration of the arrangement of the main points.

Referring to FIG. 2, the chip float 110 has a chip shape. In this case, it is necessary to induce attraction (pulling force) between the floats in order for the plurality of chip floats 110 introduced to the main points of the discussion to spread evenly in the paddy field 1.

In the present embodiment, the characteristics of hydrophilicity (property with water) and hydrophobicity (property with water) can be used together using the principle of nature. Salvinia, a natural plant, can be effectively suspended above water in a unique way that leaves both hydrophilicity and hydrophobicity on the leaves. Naturally mimicking the characteristics of the salvia may have the chip float 110 has the following functions.

The chip float 110 may be divided into an outer portion 114 and an inner portion 112 of the edge circumferential portion when viewed from above. The chip float 110 may be processed such that the outer portion 114 is hydrophilic and the inner portion 112 has hydrophobicity.

The hydrophobic processing can be processed in the form of covering the hydrophobic film. Or hydrophobic coating may be carried out.

Hydrophilic processing can be left as it is without any processing. This is because the outer portion 114 which is not hydrophobic processed may have relatively hydrophilicity compared to the inner portion 112 that is hydrophobic processed. For example, if the material is paper and / or wood, since the material itself has hydrophilicity, it will not be necessary to perform additional processing on the outer portion 114 where hydrophilicity is required.

The hydrophilic nature of the outer portion 114 causes the chip float 110 to wet its outer boundaries (when the material is paper or wood) or at least contain water droplets on the surface (if the material is plastic).

Due to the hydrophobic nature of the inner portion 112, the inside of the chip float 110 rejects the droplets and naturally pushes the droplets outward. Water droplets pushed from the inside stay at the relatively hydrophilic outer side 114 boundary. If the material is paper or wood, the water droplets make the outer portion 114 wet. When the material is plastic, the water droplets stay on the surface of the outer portion 114 to create a tensile force (pulling force) by the water.

In this state, in the case of contact with another neighboring chip float 110 (in this case, the two chip floats 110 are referred to as A chip and B chip), the boundary of the A chip (outer side) and the boundary of the B chip (outer side) are both It is wet with water (if the material is paper or wood) or has all water droplets (if the material is plastic) and has the property of attracting each other due to the tension of the water. That is, since the outer portion 114 of the chip float 110 is always kept wet, it is possible to spread evenly if a sufficient amount of the chip float 110 is supplied. Here, water providing the tensile force can be obtained from the paddy field 5.

As shown in FIG. 3, two neighboring chip floats 110a and 110b or 110b and 110c may overlap each other when each outer portion 114 is viewed from above due to the tensile force of the water. By repeating this overlapping pattern, the plurality of chip floats 110 can be evenly distributed on the field material 5.

Weed growth suppression device and method that mimics the competition structure of trees according to another embodiment of the present invention is also for reducing the damage of rice farming caused by weeds growing in paddy fields, ecologically and naturally inhibit the growth of weeds The present invention relates to a method for blocking the source of growth inhibition.

The weed growth suppression apparatus 200 mimicking the tree competition structure according to the present embodiment is a sunscreen float, and includes a plurality of sphere floats 210.

The sphere float 210 may have a sphere shape. It may be implemented in various materials such as paper, plastic, wood, and the like. For wood materials, wood types with less resin (oil) can be used.

In addition, the sphere float 210 is to block the input of sunlight, it can be made opaque.

The old float 210 may be injected into the paddy and dispersed after the seeding is completed. Since it is possible to block even the space to be planted before seeding, it is necessary to fill the rest of the discussion while the seeding is secured.

In the dispersion of the old float 210 into the paddy field, a drone may be used as a feeding device. A drone may be used to drop and disperse a predetermined quantity of sphere floats 210 at key points of discussion. Alternatively, a specially developed robot may be used to spread an appropriate amount of sphere floats 210 at key points of discussion (see FIG. 4).

In the case of the old float 210, it is necessary to induce attraction (pulling force) between the float in order to be evenly distributed in the paddy field.

Referring to FIG. 6, the spherical suspension 210a or 210b may be embodied in a hollow shape in order to maintain buoyancy. In this case, the sphere float 210a or 210b may include one or more outer layer portions 212a or 212b.

The sphere float 210 includes a first sphere float 210a having a magnetic force and a second sphere float 210b responding to the magnetic force. In the first sphere float 210a, the outer layer portion 212a may be formed of a magnet. In addition, the second sphere float 210b may have an outer layer 212b made of metal (eg, steel).

Since the magnet and the metal naturally try to adhere to each other, if a sufficient amount of the sphere float 210 is supplied, it can be spread evenly.

Some of the old suspensions (210a in FIG. 6) may have a nutrient 216 injected therein to protect young hair and promote growth. The nutrient-injected sphere suspension 210a has a discharge hole 214 penetrating through the outer layer portion 212a, so that the nutrient 216 therein can be discharged to the paddy water 5 through the discharge hole 214. Can be. The release of nutrients can promote the growth of young hair immediately after seeding.

In addition, since the nutrient is injected only to a part of the ball float 210, but not all, the weed growth inhibiting device 200, which is connected to each other by the magnetic force of the ball float 210 is sufficient to float on the paddy material 5 sufficiently. Can have buoyancy.
