Mixed planting and breeding field for rice and frog
Technical Field
The invention belongs to the field of agricultural product planting and cultivation, and particularly relates to a rice and frog mixed seed cultivation field.
Background
In the last century, frogs are very common amphibians in rice fields in rural areas of China, and mainly feed on insects and the like trapped in the rice fields. However, with the use of pesticides and the use of excessive catching and killing of frogs as table food, wild frogs become more and more rare, the ecological balance is seriously damaged, and serious pesticide pollution is also caused. Frogs have become a prohibited protective animal for killing in our country, among which frogs have been listed in the red catalogue of endangered species in the world alliance for natural protection (IUCN) 2004. With the improvement of the requirement of green safety of rice and the demand of food and medicine value of frogs, how to utilize rice fields to carry out ecological artificial breeding of frogs becomes an important research direction in recent years. The prior art CN103210811A discloses a mixed breeding and cultivating method of frogs and rice, which relates to the field construction including the field construction of a rice field and a frogs cultivation pool, the shed frame construction and the cofferdam arrangement, but the field is actually that rice is planted in the rice field and rana nigromaculata is cultivated in the frogs cultivation pool, and no really integrated mixed breeding is formed. By using the method, if the rana nigromaculata is bred in the rice field, the subsequent breeding management is very difficult.
Disclosure of Invention
The invention aims to provide a rice and frog mixed seed breeding field convenient for frog breeding management.
The purpose of the project is realized by the following technical scheme:
a mixed rice and frog planting and breeding field is characterized by comprising a planting and breeding area and a protective net rack arranged around the planting and breeding area, wherein the protective net rack comprises inverted-L-shaped protective columns; the planting and breeding area comprises a rice planting area, a ditch area arranged around the rice planting area and a land area arranged outside the ditch area; the ditch area comprises a ditch bottom, a first ditch wall arranged on one side of the rice planting area and a second ditch wall arranged on one side of the land area, the horizontal width of the maximum width position of the ditch area is not more than 100cm, the height of the rice planting area is 40-60cm higher than the ditch bottom, and the height of the land area is 20-40cm higher than the rice planting area; the straight line distance between any point A of the rice planting area and a point B closest to A in the land area on the same horizontal plane is not less than 70cm and not more than 600 cm.
The planting area is used for planting rice and breeding frogs, the protection rack will the planting area surrounds, prevents that the frogs from following the planting area escapes, the protection post is the type of falling L, has supported promptly the protection rack provides the support for building the sunshade again. The rice planting area is used for planting rice, the rice can shade the frog, the frog preys on insects in a rice field, excrement of the frog becomes a base fertilizer of the rice, and pesticide and chemical fertilizer are not needed in the whole rice planting process. The ditch area is used for draining, supplying and storing water in the rice field, and also provides one of activity places for the frogs (including tadpole periods). The land area is mainly used for feeding areas and land activities of frogs.
The ditch bottom is 40-60cm lower than the rice planting area, the ditch area can store deeper water, which provides a heat preservation place for the frog and also provides a water source guarantee for the frog in the period of water drainage and soil hardening of the rice planting area in the rice field.
Adult frogs do not like to move in water for a long time, and must have enough land space for frogs to move throughout the period of rice planting, the land area is the main land space for frogs to eat and move, and the height of the land area is set to be 20-40cm higher than the rice planting area by the inventor so as to ensure that the land area is not submerged in water during the whole planting process.
When frogs are caught on the market, they are mainly caught in the land and ditch areas. The inventors have found that when the linear distance between the points a and B on the same horizontal plane is too small, the number of frogs that are frightened to escape to the seed rice area during catching is large. In the mixed breeding process of the rice and the frogs, the staple food of the frogs is mainly manually fed in the land area, and when the linear distance between the point A and the point B on the same horizontal plane is too large, namely the position of the frogs in the rice area is too far away from the land area, the feeding training of the frogs is extremely not facilitated, so that the domestication degree of the frogs is low, and the individual growth difference between the frogs is large.
Preferably, the rice and frog mixed seed cultivation field is characterized in that trapezoidal islands are arranged in the seed rice area, the number of the trapezoidal islands is 1-4 per square meter, the vertical height of each trapezoidal island is 5-10cm, and the projection area of each trapezoidal island in the gravity G direction is 100-400 square centimeters.
During the growth of rice, the water depth required to be provided by the rice planting area can exceed 5cm in some periods, most of adult frogs can only float in water, and the frogs leave the rice planting area in a large amount due to the fact that the frogs do not like to float in the water for a long time. Therefore, the inventor sets the trapezoidal island, so that the frog selects a favorite land and water environment in the paddy planting area by using the trapezoidal island.
Preferably, the rice and frog mixed seed culture field is characterized in that the straight line distance between any point A of the seed rice area and a point B closest to the point A in the land area on the same horizontal plane is not less than 80cm and not more than 400 cm.
Preferably, the rice and frog mixed seed culture field is characterized in that an included angle alpha formed by the first trench wall and the gravity direction G towards the land area side is larger than 0 degree and not larger than 10 degrees.
When the water level is lowered below the rice planting area, the included angle alpha is convenient for the frog to move between the ditch area and the rice planting area; when catching the frog, the included angle alpha can prevent the frog catching net wall from bumping and falling off mud on the first ditch wall when rising from the water bottom to frighten the frog, and the included angle alpha and the height of the first ditch wall are arranged to make the frog difficult to rapidly escape to the rice planting area.
Preferably, the rice and frog mixed planting and raising field is characterized in that the included angle beta formed by the second groove wall and the gravity direction G towards the rice planting area side is not less than 30 degrees and not more than 59 degrees.
The included angle beta is set, so that the frog can move in the ditch area and the land area conveniently, and the tadpole can eat food conveniently in the tadpole period. The inventor also finds that the included angle beta is obviously larger than the included angle alpha, and after long-term cultivation and domestication, frogs can preferentially escape to the land area when only water exists in the ditch area and the ditch area is frightened.
Preferably, the mixed rice and frog planting farm is characterized in that the second trench wall and the surface of the land area are paved with a frog catching net, the frog catching net comprises a first net edge close to one side of the trench bottom and a second net edge close to one side of the protection net rack, and the first net edge is provided with a pendant for sinking the frog catching net.
The frog catching net is right the surface soil of second ditch wall has the effect of consolidating soil, is located protection rack one side the second net edge of frog catching net paste ground or paste the protection rack fixed can, be located one side at the bottom of the ditch the first net edge of frog catching net passes through the piece that weighs down sink in the ditch district, when the frog is caught to needs, rise first net edge can.
Preferably, the rice and frog mixed seed farm is characterized in that the protection column comprises a vertical rod standing in a foundation and a transverse rod transversely arranged at the upper end of the vertical rod; the height of the cross bar from the land area is 50-200cm, and a shed frame for climbing the vines is laid on the cross bar.
The protective columns play a supporting role, the vertical rods and the cross rods form an inverted L shape, and the vertical rods are driven into a foundation, so that the stability of the protective net rack and the stability of the cross rods are ensured; the cross bar ensures the stability of the shelving on the cross bar. The transverse rod and the shed frame provide climbing support for the vines, the vines such as grapes form a natural sunshade after climbing, the natural sunshade is ecological and attractive, and the natural sunshade formed by the vines has rich gaps, so that the natural sunshade has a better sunshade and ventilation effect, is not easy to turn over by strong wind, and is more beneficial to cultivation of frogs. The inventor finds that when the height of the cross rod from the land area is set to be 50-200cm, the sunshade formed by climbing of the lianas has better sunshade and ventilation effects, strong wind resistance and no limit on the activity space of the frogs, and particularly when the height of the cross rod from the land area is set to be 100-150cm, insects led by the lianas are easy to be caught by the frogs.
Preferably, the rice and frog mixed seed culture farm is characterized in that the cross bar comprises a tail end close to the seed culture area, the tail end is provided with a first outlet with a downward opening, and the projection of the first outlet in the gravity direction G is located at the bottom of the ditch.
The inventor finds that when the projection of the first outlet in the gravity direction G is positioned at the bottom of the ditch, on one hand, the sunshade effect is good, and on the other hand, the net-hauling and frog-catching of the frog-catching net is facilitated.
Preferably, the mixed rice and frog planting farm is characterized in that the vertical rod is provided with a second outlet with an outward opening, communicated empty channels are formed in the vertical rod and the cross rod along the rod, and the first outlet is communicated with the second outlet through the empty channels.
The empty passage, the first outlet and the second outlet are used for the shuttling of a rope, one end of the rope is connected with the first net edge, and the other end of the rope sequentially shuttles through the first outlet, the empty passage and the second outlet and then is fixed. When the frog needs to be caught, the rope at the second outlet end is slowly pulled, and the first net edge can be lifted along with the rope. Because the rope threads shuttle from the vertical rods and the cross rods, the interference of vine plants on the rope threads is effectively avoided, and the high efficiency of frog catching is ensured.
Preferably, the rice and frog mixed seed culture farm is characterized in that the protection columns are arranged at a density of 100-200cm in distance.
The density that sets up of protection post not only directly influences the safety and stability of protection rack, also directly influences the uniformity when first net reason rises (when rising, first net reason is the highest with the rope line junction, and the intermediate position department of two junctions is minimum, and the interval of two junctions is too big can lead to connecting the difference in height that is in intermediate position department too big), sets up that the density too big can lead to the cost to improve by a wide margin, sets up the density undersize and can lead to safety and stability not enough and rise uniformity when first net reason is not enough and then influences the frog catching effect.

Detailed Description
The foregoing aspects of the present invention are described in further detail below by way of examples, but it should not be construed that the scope of the above-described subject matter of the present invention is limited to the following examples, and that all the technologies implemented based on the above-described aspects of the present invention are within the scope of the present invention.
Detailed description of the preferred embodiment 1
As shown in fig. 1-3, the inventor has constructed a mixed rice and frog planting farm, which comprises a planting area 1 and a protective net rack 2 arranged around the planting area 1, wherein the protective net rack 2 comprises an inverted L-shaped protective column 21. The inventor utilizes planting and breeding district 1 is used for planting the rice and breeding the frog, utilizes protection rack 2 will planting and breeding 1 encirclement in district prevents that the frog from following planting 1 escape in district, protection post 21 is the type of falling L, has supported promptly protection rack 2 provides the support for building the sunshade again.
Planting and breeding district 1 includes kind rice district 11, locates ditch district 12 around kind rice district 11, locate the land district 13 in ditch district 12 outside. The rice planting area 11 is used for planting rice, the rice can be used for shading the frog, the frog preys on insects in a rice field, excrement of the frog becomes a base fertilizer of the rice, and pesticide and chemical fertilizer are not needed in the whole planting process of the rice. The gully 12 is used for drainage, water supply and water storage of the paddy field and also provides one of activity places for the frogs (including tadpole period). The land area 13 is mainly used for feeding areas and land activities of frogs.
The gutter area 12 includes a gutter bottom 121, a first gutter wall 122 provided on the side of the planting area 11, and a second gutter wall 123 provided on the side of the land area 13. In order to provide a heat preservation place and water source guarantee for the frogs and prevent the land areas 13 from being too close to the seed rice area 11 to influence the frog catching success rate, the inventor sets the horizontal width of the maximum width position of the ditch area 12 to be 80cm and sets the height of the seed rice area 11 to be 50cm higher than the ditch bottom 121. Since adult frogs do not like to move in water for a long time, there must be enough land space for frogs to move throughout the period of rice planting, and the land area 13 is the main place where frogs eat, the inventors set the height of the land area 13 to be 30cm higher than the seed rice area 11 to ensure that the land area 13 is not flooded throughout the planting process.
The inventor finds that the main food of the frogs is mainly the artificial feeding of the land area 13 in the mixed breeding process of the rice frogs, and the feeding and the training of the frogs are extremely not facilitated when the positions of the frogs in the rice planting area 11 are far away from the land area 13, so that the domestication degree of the frogs is low, and the individual growth difference among the frogs is large. Therefore, the width of the planting area is set to 400cm, and at the moment, the straight line distance of the frog on the same horizontal plane between any point A of the planting area 11 and the point B closest to A in the land area 13 is not more than 600cm, so that the feeding training of the frog is smoothly carried out.
During the growth of rice, the water depth required to be provided by the planting area 11 may exceed 5cm in some periods, and most of the adult frogs can only float in the water, but the frogs leave the planting area 11 in a large amount because the frogs do not like to float in the water for a long time. Therefore, the inventor sets the trapezoidal island 111 in the paddy field 11 in an amount of 1-4/square meter, so that the frog selects a favorite amphibious environment using the trapezoidal island 111 in the paddy field 11. According to the water supply and drainage conditions of the rice area 11 and the habit of frogs, the vertical height of the trapezoidal island 111 is set to be 5-10cm, and the projection area of the single trapezoidal island 11 in the gravity G direction is set to be 100-400 square centimeters.
When the water level drops below the planting rice area 11, the frog needs to reach the ditch area 12 to drink water, so the inventor sets the included angle alpha formed by the first ditch wall 122 and the gravity direction G towards one side of the land area 13 to be 8 degrees, and the included angle alpha is convenient for the frog to move between the ditch area 12 and the planting rice area 11. The angle α also prevents the web wall of the net 3 from hitting the mud on the first gutter wall 122 and catching the frog when the frog is caught, and the angle α and the height of the first gutter wall 122 are set so that the frog cannot escape to the paddy field 11 quickly.
Food of the frogs is mainly from artificial feeding, the frogs can conveniently move in the ditch region 12 and the land region 13, the frogs can conveniently eat during tadpoles, and an included angle beta formed by the second ditch wall 123 and the gravity direction G towards one side of the rice growing region 11 is set to be 40 degrees. Since the angle beta is significantly greater than the angle alpha, the inventors have found, after long-term domestication of the culture, that when only water is present in the raceway region 12 and there is a surprise in the raceway region 12, frogs will preferentially escape to the land region 13, which is very advantageous for their capture.
In order to facilitate frog-catching, the inventor lays a frog-catching net 3 on the surface of the second trench wall 123 and the land 13, the frog-catching net 3 comprises a first net edge 31 close to one side of the trench bottom 121 and a second net edge 32 close to one side of the protection net rack 2, and the inventor fixes the second net edge 32 to the protection net rack 2 in a sticking manner. In order to facilitate the sinking of the frog-catching net 3 and to provide tension to the second trench wall 123, the inventor provides a drop 33 at the first net rim 31, the tension is generated to make the frog-catching net 3 have a soil-fixing effect on the soil on the surface of the second trench wall 123, and when the inventor needs to catch a frog, the inventor raises the first net rim 31.
In order to play a role of the protection post 21 in frog cultivation more, the inventor carries out innovative design on the protection post 21, and the protection post 21 comprises a vertical rod 211 standing in the foundation and a transverse rod 212 transversely arranged at the upper end of the vertical rod 211. The protective column 21 has a supporting function, the vertical rod 211 and the cross rod 212 form an inverted L shape, wherein the vertical rod 211 is driven into a foundation, so that the stability of the protective net rack 2 and the cross rod 212 is ensured; the cross bar 212 ensures stability of the shelving 4 laid on the cross bar 212. The cross rod 212 and the shed frame 4 provide climbing support for vine plants, the natural sunshade is formed after the vine plants such as grapes are climbed, the ecological and attractive appearance is achieved, and the natural sunshade formed by the vine plants has rich gaps, so that the natural sunshade has a better sun-shading and ventilating effect, is not easily turned over by strong wind, and is more favorable for cultivation of frogs. The inventor finds that the height of the cross bar 212 from the land 13 directly affects the sunshade ventilation effect of the sunshade formed by climbing of the vines and the wind resistance of the sunshade, and the frog activity is limited and the growth of the frog is not facilitated when the height is too low. The inventor sets the height of the cross bar 212 to be 130cm from the land area 13 in consideration of the conditions of damp and hot weather, typhoon weather and the like in the local climate, so that the sunshade gives consideration to the functions of sunshade ventilation, wind resistance and the like, and insects led by the vine plants are easy to be caught by the frogs.
The cross bar 212 includes a tail end 2121 adjacent the seed rice area 11, and the inventor has provided a first downwardly opening outlet 2122 at the tail end 2121 in order to facilitate pulling of the frog-catching net 3 by means of the string. In order to improve the sunshade effect and the success rate of capturing frogs, the inventor reasonably sets the length of the cross bar 212 based on the position of the projection of the first outlet 2122 in the gravity direction G on the trench bottom 121.
The inventor finds that if the rope for pulling the frog catching net 3 passes through the shed frame 4, the rope is easily twisted due to the winding property of the growth of the vines, so that the net cannot be smoothly taken down or collected, and the frog is easy to escape due to large movement and static when the rope is threaded. Therefore, the inventor provides a second outlet 2111 which is open outwards on the vertical rod 211, the vertical rod 211 and the inner part of the cross rod 212 are provided with a hollow channel 213 which is communicated along the rod, and the first outlet 2122 and the second outlet 2111 are communicated through the hollow channel 213. One end of the rope is connected with the first net edge 31, and the other end of the rope successively passes through the first outlet 2122, the empty passage 213 and the second outlet 2111 and then is fixed. When the frog needs to be caught, the rope at the end of the second outlet 2111 is slowly pulled, and the first net edge 31 can be lifted along with the rope. Because the rope threads shuttle back and forth from the vertical rods 211 and the cross rods 212, the interference of vine plants on the rope threads is effectively avoided, and the high efficiency of frog catching is ensured.
The density of setting up of protection post 21 not only directly influences the safety and stability of protection rack 2, also directly influences the uniformity when first net edge 31 rises (when rising, first net edge 31 is the highest with the rope line junction, and the intermediate position department of two junctions is the lowest, and the interval of two junctions is too big can lead to connecting the difference in height that is in intermediate position department too big), and it can lead to the cost to improve by a wide margin to set up the density too big, and it can lead to the safety and stability not enough and rise to set up the density undersize the uniformity when first net edge 31 is not enough and then influences the frog catching effect. The inventors have set the protection posts 21 in a density of 100cm each, in combination with the local climate, in particular with typhoon weather.
Based on the habit of frogs, the inventor only needs to adjust the water level of the planting and breeding area 1 (for example, when the water depth of the planting and breeding area is adjusted to be about 5cm, frogs like moving in the planting and breeding area 11; when the water depth of the planting and breeding area 11 is adjusted to be more than 15cm, frogs gather to the land area 13 and the second ditch wall 123), place food, set the frog catching net 3 and the like by the scheme of the specific embodiment 1, so that the efficient breeding and management of frogs in the mixed planting and breeding process of the frogs can be realized.
