Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a duck farm in which rice cultivation and duck breeding can be performed in parallel.

[0002]

2. Description of the Related Art In recent years, so-called duck farming has been practiced in which duck is bred in paddy fields where paddy rice is cultivated. In the duck farming method, the breeding duck eats grass and insects in the paddy field to control weeds and pests.Therefore, while controlling the use of chemicals such as herbicides and disinfectants, Increase can be achieved.

When the duck farming is carried out, the duck being bred escapes or dogs and weasels invade and attack the duck in a normal paddy field. Therefore, some protection measures should be provided around the paddy field. A duck farm has been formed by the establishment. Conventional protection measures include:
A method has been adopted in which net fences or electric wires are stretched along ridges surrounding rice fields.

FIG. 5 is a partial perspective view showing an example of a conventional duck farm. A plurality of electric wires 52 are horizontally stretched at regular intervals along a ridge 51 around a paddy field 50. I have. These electric wires 52 are connected to one output terminal 54 of a power supply device 53 operated by a commercial power supply, and the other output terminal 55 is connected to a ground wire 56 buried underground.

When a duck or a dog bred in the paddy field 50 touches the electric wire 52, the electric current flowing through the electric wire 52 causes a light electric shock. Will not enter the paddy field 50.

[0006]

In the case of the conventional duck farm shown in FIG. 5, the gap between the electric wires 52 stretched around the paddy field 50 or between the electric wire 52 and the ground is relatively large, and the inside and outside of the paddy field 50 are different. The duck may escape from the paddy field 50 through these gaps, or a dog or the like may enter the paddy field 50 through these gaps, and the protective function is insufficient.
The electric wire 52a located at the lowermost position is 10c from the ground.
Since the distance is only about m, there is a problem that a short-circuit occurs in contact with the ground or the water surface, or that the weeds extending from the ridges touch the electric wire 52a to lower the voltage.

In the case of a conventional duck farm, if a duck bred in the paddy field 50 touches the electric wire 52 and receives an electric shock,
Thereafter, the electric wire 52 is repelled.
The duck does not approach the area about 2 to 3 m away from, that is, the outer peripheral portion of the paddy field 50 at all. For this reason, weeds and the like prosper on the outer peripheral portion of the paddy field 50, and the control of pests and insects is incomplete, and the advantages of the duck farming method cannot be fully exhibited.

On the other hand, in the case of a duck farm using a net fence, when a weed on a row is cut using a brush cutter or the like, the cutter of the brush cutter touches the net fence and cuts the net fence. It may be involved, which is a hindrance to weeding work.

[0009] The problem to be solved by the present invention is that a duck farm that does not cause troubles such as invasion of a foreign enemy, escape of a duck, or electric shock, makes full use of the advantages of the duck farming method, and can increase the yield. Is to provide.

[0010]

A duck farm according to the present invention comprises a shielding plate erected substantially vertically on the ground, a horizontal plate disposed substantially horizontally on the shielding plate, and an upper part of the horizontal plate. A protection fence constituted by a plurality of electric wires stretched substantially horizontally at intervals is provided around the field.

[0011] With this configuration, the field is surrounded by the protective fence in which the shielding plate, the horizontal plate, and the plural wires are arranged upward from the ground. Invasion of foreign enemies such as dogs and weasels,
Troubles such as escape and electric shock of duck bred in the field do not occur. In addition, the duck does not repel the protective fence due to fear of electric shock, and eats grass and insects while moving around the field evenly, so that the advantages of the duck farming method are fully exhibited and the yield can be increased.

In addition, by forming a water channel between the outer periphery of the field and the protective fence, the water channel can be used as a movement route of a duck when growing rice in the field, and water management in the field can be performed. Can be used effectively.

[0013] Further, by providing a reservoir connected to a water channel in a part of the field, the reservoir can be used as an emergency evacuation site when a duck bred in the field is attacked by birds and beasts. Alternatively, fish can be raised in the reservoir.

Further, by forming at least a part of the wall surface of the reservoir with a stone wall, the gap between the stone walls can be used as a home for fish bred in the reservoir.
