BACKGROUND ART

At present, fish and shrimp farming or duck farming in paddy fields has become a major comprehensive utilization mode of paddy fields. Fish farming in a paddy field refers to simply digging a ditch or a pond in the paddy field and then putting fish fry in the ditch or pond for farming. In practice, the ditch or the pond is often part of the paddy field. Such a mode exhibits great difficulties in paddy field management and farming. Specifically, it would be hard to carry out mechanical rice harvesting; the use of pesticides will have negative effects on fish, and thus, the use of pesticides is always limited, resulting in decrease in rice output. During fish farming, it would be impossible to realize accurate feeding or know how farming goes. Usually, the rice and fish farming depend on the weather. During mixed fish and duck farming, the fish fry needs to be big enough so as not to be eaten by ducks, and the ducklings also need to be big to guarantee the survival rate.

The opening-closing unit 25 includes: slow-speed motor 17, relay switch 26, slow-speed gear 27, and positive and negative semi-circle gear 28.

The specific structure and functions of the fine management system for integrated farming of agriculture and fisheries of the invention are described below.

Design of paddy field 1: the paddy field 1 is 60 m long and 60 m wide with an area of 5.4 mu and mainly used for growing rice. The rice growing area is not less than 90% of the total area. The fish ditch 2 for farming fishes and the duck ridge 3 for farming ducks, which are perpendicular to each other, are dug in the middle of the paddy field 1. The cross-shaped pavilion 8 is located at the intersection of the fish ditch and the duck ridge. Rice is planted in other field parcels.

The fish ditch 2 is 1.2 m deep and 2 m wide. A ditch ridge 14 is formed at the junction of the fish ditch 2 and the paddy field 1. The ditch ridge is 0.1 m high and the field ridge 4 is 0.4 m high so that water can be stored in the paddy field 1 when the water level of the fish ditch 2 is reduced. When the paddy field 1 is full of water, the ditch ridge 14 can be flooded with water. The ditch ridge 14 has openings 15 at intervals of 5 m. When the water level of the paddy field 1 is lower than the ditch ridge 14, the openings can be opened to serve as fish passages. The fish ditch planting parcel 6 widened by 0.5 m is formed at the ditch ride 14 on one side of the cross-shaped pavilion 8, and climbing plants such as towel gourd and grape are grown in this parcel. Correspondingly, the fish ditch frame 11 is arranged over the fish ditch 2. Thus, in high temperature seasons, the effects of sun-shading and cooling for fishes can be achieved.

The duck ridge 3 is 2 m wide and 0.45 m high. The duck ridge 3 is surrounded with the surrounding net 10 which can be automatically or manually elevated and lowered down.

When the surrounding net is elevated, ducks can move freely within the whole area of the duck ridge 3, the paddy field 1 and the fish ditch 2. When the surrounding net is lowered down, ducks can be confined within the ridge. The duck roads 13 are formed on the left and right sides of the duck ridge 3 adjoining the cross-shaped pavilion 8, allowing ducks to go up and down in different directions and guiding the ducks to take a rest in the cross-shaped pavilion 8. The duck ridge planting parcel 5 widened by 0.5 m is formed at the duck ridge

3 on one side of the cross-shaped pavilion 8, and climbing plants such as towel gourd and grape are grown in this parcel.

Correspondingly, the duck ridge frame 9 is arranged over the duck ridge 3. Thus, in high temperature seasons, the effects of sun-shading and cooling for ducks can be achieved.

The cross-shaped pavilion 8 is covered with a roof and has four pavilion pillars. The floor of the cross-shaped pavilion is replaced by a fine-mesh net on which ducks can take a rest. Duck manure may drop down through the fine-mesh- net, with particles serving as fish baits and soluble substances as fertilizers entering the paddy field 1. A feeder, a water faucet and an automatic control device may be mounted on the cross-shaped pavilion 8.

On the one hand, the automatic control device functions in controlling opening and closing of the surrounding net 10 of the duck ridge 3. A triangular support 23 and an eccentric stone 24 are arranged at an outer end of the surrounding net 10. An inhaul cable 19 is provided on an upper edge of the surrounding net 10, and a support rod 21 for supporting a net piece is disposed at an inner end of the surrounding net. When closing, the triangular support 23 is capable of being pulled up by the inhaul cable 19 and rests against a stop pillar 22 so that the surrounding net 10 is pulled up; when opening, the eccentric stone 24 causes the triangular support 23 to fall down under the action of gravity so that the surrounding net 10 is lowered down; thus, the action of elevating and lowering down the surrounding net 10 is achieved. The opening-closing unit 25 is used to pull the inhaul cable 19 to control opening and closing of the surrounding net 10. On the other hand, a switch is additionally provided to control the feeder and ringing sound. The feeder has a time delay unit that delays the start of the ringing sound.

The mounting structure of the opening-closing unit 25: the opening-closing unit includes a slow-speed gear 27 connected to a slow-speed motor 17, a chain, a positive- negative semi-circle gear 28, a relay switch 26 and a control circuit as well as an inhaul cable wheel. The slow-speed gear 27 and the inhaul cable wheel are coaxial with the slow-speed motor 17. The slow-speed gear 27 drives the positive-negative semi-circle gear 28 by means of the chain. The relay switch 26 is connected in parallel to the motor. A contact is disposed on the positive-negative semi-circle gear 28; and an opening switch and a closing switch are disposed in circuits of opening and closing. The inhaul cable 19 is wound around the inhaul cable wheel. The inhaul cable 19 moves along with positive rotation and negative rotation of the motor, causing the surrounding net 10 to be opened and closed. Based on the stretching and retracting length of 2 m of the inhaul cable 19 when opening and closing, the diameters of the slow- speed gear 27, the inhaul cable wheel and the positive- negative semi-circle gear 28 are determined to be 0.05 m, 0.21 m and 0.3 m, respectively. After the inhaul cable wheel makes three revolutions, the surrounding net 10 is exactly pulled up or lowered down. When the slow-speed gear 27 makes three revolutions, the positive-negative semi-circle gear 28

Just makes 0.5 revolution. When the positive-negative semi- circle gear 28 makes 0.5 revolution positively or negatively, the surrounding net 10 is exactly pulled up or lowered down.

When opening, a knob is shifted from the 0 position to the open position so that the corresponding circuit is energized.

The relay switch 26 disengages, and the motor rotates positively, causing the eccentric stone 24 to descend, so that the surrounding net 10 is lowered down. In this case, the contact of the positive-negative semi-circle gear 28 exactly ejects the opening switch in the circuit so that the circuit is disconnected. The relay switch 26 is closed so that the surrounding net 10 keeps open. An indicator lamp is then turned off and the switch resets to the 0 position. When closing, the knob is shifted from the 0 position to the closed position so that the corresponding circuit is energized. The relay switch 26 disengages and the motor rotates negatively so that the eccentric stone 24 and the surrounding net 10 are completely pulled up. In this case, the contact of the positive-negative semi-circle gear 28 exactly ejects the closing switch in the circuit so that the circuit is disconnected. The relay switch 26 is closed so that the surrounding net 10 keeps closed. The indicator lamp is then turned off and the switch resets to the 0 position.

Example 1: rice is planted in the paddy field only once a year.

In spring, 120 grass carps (each weighing 250 gj, 120 bream fishes (each weighing 150 g) and 120 crucian carps (each weighing 100 g), 360 in total, are put into the fish ditch 2, averagely 3 for each square meter. 120 ducks are farmed, averagely 1 for each square meter. The fishes and the ducks are farmed in the fish ditch 2 and the surrounding net 10, respectively. The paddy field 1 is levelled at the end of April and filled with water to grow rice. When the rice turns green and there are weeds and small animals in the field, the openings 15 are opened to feed water until a water depth of 15 cm is achieved. Fish fingerling can go in and out of the paddy field 1 freely, and is fed once at dusk. Feeding domestication is carried out for one week: the power supply for feeding is switched on and the ringing sound is given off; and the double-opening feeder operates 3 minutes later to put feeds into the fish ditch 2 and within the surrounding net 10, respectively. The amounts of feeds for domestication are determined according to a conventional farming method.

After one week, the ducks and the fishes will gather under a feed table after hearing the ringing sound. The ducks and the fishes are fed once each day at dusk according to the conventional method. Since the fishes are too big to be swallowed by the ducks, the surrounding net 10 is opened every morning, allowing the ducks to move freely within the whole area. After feeding at dusk, the surrounding net 10 is closed, allowing the ducks to take a rest under the cross-shaped pavilion 8 or the frame. When the weather is hot in summer, the fishes and the ducks will gather under the frames at a lower temperature to take a rest around noon. During drying of the paddy field 1, application of fertilizers and spraying of pesticides, the openings 15 are opened to reduce the water level of the fish ditch 2 to be lower than the water level of the paddy field 1, and the ducks are farmed within the surrounding net 10. In autumn, 112 commercial ducks, 130 kg of grass carps, 80 kg of gurnards and 75 kg of crucian carps are harvested. The area of rice is reduced by about 7%, but the yield is increased by about 10%. The application of fertilizers is reduced by 60%, and no pesticide is used. The fishes and the ducks have no disease and grow healthily and strongly.

Example 2: wheat and rice are successively planted in the paddy field.

In spring, 120 grass carps (each weighing 250 9), 120 bream fishes (each weighing 150 g) and 120 crucian carps (each weighing 100 gq}), 360 in total, are put into the fish ditch 2, averagely 3 for each square meter. 120 ducks are farmed, averagely 1 for each square meter. The fishes and the ducks are farmed in the fish ditch 2 and the surrounding net 10, respectively. After the wheat is harvested in May, the paddy field 1 is levelled and filled with water to grow rice.

When the rice turns green and there are weeds and small animals in the field, the openings 15 are opened to feed water until a water depth of 15 cm is achieved. Fish fingerling can go in and out of the paddy field 1 freely, and is fed once at dusk. Feeding domestication is carried out for one week: the power supply for feeding is switched on and the ringing sound is given off; and the double-opening feeder operates 3 minutes later to put feeds into the fish ditch 2 and within the surrounding net 10, respectively. The amounts of feeds for domestication are determined according to a conventional farming method. After one week, the ducks and the fishes will gather under the feed table after hearing the ringing sound.

The ducks and the fishes are fed once each day at dusk according to the conventional method. Since the fishes are too big to be swallowed by the ducks, the surrounding net 10 is opened every morning, allowing the ducks to move freely within the whole area. After feeding at dusk, the surrounding net 10 is closed, allowing the ducks to take a rest under the cross-shaped pavilion 8 or the frame. When the weather is hot in summer, the fishes and the ducks will gather under the frames at a lower temperature to take a rest around noon.

During drying of the paddy field 1, application of fertilizers and spraying of pesticides, the openings 15 are opened to reduce the water level of the fish ditch 2 to be lower than the water level of the paddy field 1, and the ducks are farmed within the surrounding net 10. In autumn, 112 commercial ducks, 130 kg of grass carps, 80 kg of gurnards and 75 kg of crucian carps are harvested. The area of rice is reduced by about 7%, but the yield is increased by about 10%. The application of fertilizers is reduced by 60%, and no pesticide is used. The fishes and the ducks have no disease and grow healthily and strongly. The foregoing descriptions are merely illustrative, but not limiting of the invention. The scope defined by the invention is as set forth in claims, and modifications in any form can be made within the protection scope of the invention.
