Description

Technical Field

[0001] The invention belongs to the technical field of planting and breeding, and in particular relates to a rice-loach co-cultivation planting and breeding device. Background Art

[0002] Rice and loach farming is a production method that organically combines aquaculture with planting. Through the principle of symbiosis between rice and loach, water and land resources are fully utilized to increase the yield of rice fields and fish. This technology is not only conducive to the green development of the environment, but also effectively promotes the economic growth of farmers. By using loaches on the surface of rice fields, loaches can be used to obtain loach products, eat pests and weeds in rice fields, excrete manure, and turn over the soil to promote fertilizer decomposition, creating good conditions for rice growth, which can generally increase rice production by about 10%.

[0003] The cultivation of loaches in rice fields began in the mid-1950s, mainly based on natural fishing, with artificial breeding in a secondary position. With the development of aquaculture, loach farming has gradually become a characteristic aquaculture, and farmers are encouraged to use rice fields and ponds to cultivate loaches to increase their income. With the continuous development of rice field fish farming technology, rice field loach farming has the characteristics of low investment and quick results. Generally, rice fields with good water retention and slow leakage are selected. The water depth of the rice fields is kept above 20 cm before transplanting rice seedlings. After 4 months of breeding, they can be caught and sold on the market. With the development of loach farming, some problems have also been exposed. Due to the dense seedlings, it provides an ideal place for wild animals to move, hide and forage. Birds, snakes and rats are all natural enemies of loaches. In addition, because the rice fields are shallow and the bottom is flat, the concealment is poor, and the silt is shallow after the fields are dried. Loaches cannot escape when they are suddenly attacked by enemies, resulting in a poor survival rate in the process of rice field loach farming, which needs further improvement. Summary of the invention

[0004] The invention provides a rice-loach co-cultivation breeding device, which can solve the drawbacks of low survival rate due to susceptibility to natural enemy attack in the current rice field loach breeding process. The invention achieves the purpose of breeding loaches with high survival rate while increasing rice yield.

[0023] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an embodiment of the present invention provides a rice-loach co-cultivation breeding device, including a plurality of planting blocks 3 arranged in an array, and each planting block 3 is fixed above the rice field bottom mud 6 by a fixing rod 7, and a loach nest 5 is formed between the planting block 3 and the rice field bottom mud 6. An organic pile 4 is arranged between two adjacent planting blocks 3, and the organic pile 4 has a conical structure. The fixing rod 7 is fixed in the fixing hole 8 of two adjacent planting blocks 3 in the rice field 1. The planting block 3 is preferably a rectangular structure with a width of 50 to 60 centimeters, an area of ​​0.5 to 3 square meters, and a distance between two adjacent planting blocks 3 of 1 to 2 meters.

[0025] The cultivation and breeding of rice and loach in this embodiment includes rice planting, making loach nests, setting up organic piles, stocking loach seedlings and harvesting rice and loach. After the rice field 1 is leveled, a ridge 2 is set around the rice field 1. A plurality of planting blocks 3 are arranged in an array in the ridge 2. The planting block 3 is a floating material for planting rice. The area of ​​the planting block is determined according to the stocking amount of loach. A planting block of 1 to 2 square meters is used for every 200 loaches. If it is too narrow, it is not conducive to hiding. If it is too wide, it is easy to lack oxygen in the middle. If the distance between each planting block is too large, it is not conducive to the emergency hiding size of loach. There is a planting nest 3-1 on the planting block 3 for planting rice plants. There are holes on the planting block 3 for connecting with the fixing rod 7 to ensure that the planting block 3 cannot be translated and can only move up and down with the rise and fall of the water surface. After the planting block 3 is set, rice seeds are scattered in the rice field 1, and more are appropriately scattered near the planting block 3 for transplanting to the planting block 3 later.

[0026] like Figure 5 and Figure 6 As shown, a seeder is provided on the planting block 6, and the seeder includes a hopper 9, a bracket 10, a base frame 11, a feeder 12, a DC air pump 13, an air pipe 14, a branch pipe 15 and a discharge pipe 16; the hopper 9 is used to hold rice seeds, and includes a straight bucket structure 9-1 at the upper part and a partial funnel structure 9-2 at the lower part, and a feeder 12 is provided at the outlet of the partial funnel structure 9-2. A bracket 10 is connected below the straight bucket structure 9-1, and the bracket 10 is connected to the base frame 11. A DC air pump 13 is provided inside the bracket 10, and the DC air pump 13 is connected to the air pipe 14. The feeder 12 is connected to the air pipe 14 through a branch pipe 15, and the end of the air pipe 14 is connected to the discharge pipe 16, and the end of the discharge pipe 16 is connected to the nozzle 17, and the nozzle 17 is used to throw rice seeds into the planting nest 3-1 of the planting block 3 and the rice field 1 near the planting block 3.

[0027] When part of the rice plant's roots are embedded in the paddy field mud 6, part of the roots surround the rice plant to form a root cluster between the planting block 3 and the paddy field mud 6, a loach nest 5 rich in dissolved oxygen suitable for loach to live and hide is formed between the root clusters under the planting board 3.

[0028] The discharge pipe 16 comprises a hard pipe 16-1, a soft pipe 16-2 and a diverging part 16-3, wherein the soft pipe 16-2 connects two spaced parts of the hard pipe 16-1, and the diverging part 16-3 is located at the end of the hard pipe 16-1, and the diverging part 16-3 is a fan-shaped structure with radial strips inside to promote uniform dispersion of rice. The direction of the soft pipe 16-2 is manually controlled during operation.

[0029] like Figure 7 and Figure 8As shown, the feeder 12 includes a strip 12-1, a wind plate 12-2, a shaft 12-3 and a shaft ring 12-4. The strip 12-1 is a long strip structure. The shaft 12-3 is fixed on the long side of the strip 12-1. Shaft rings 12-4 are provided at both ends of the shaft 12-3. The strip 12-1 can rotate around the shaft 12-3. When the strip 12-1 is opened, the rice seeds can fall. When it is not working, the strip 12-1 plays a sealing role to prevent the rice seeds from falling.

[0030] The wind plate 12-2 is fixed on the shaft 12-3, and the wind plate 12-2 is perpendicular to the plane where the strip plate 12-1 is located. A branch pipe opening 15-2 is connected to the center of the wind plate 12-1, and the branch pipe opening 15-2 is the end of the branch pipe 15. High-pressure gas flows out of the branch pipe 15 to blow the wind plate, and the wind plate 12-2 drives the shaft 12-3 to rotate, and then drives the strip plate 12-1 to open the slits, so that the rice seeds fall.

[0031] There is an impeller blade 15-3 at the branch pipe opening 15-2. The gas drives the impeller blade 15-3 to rotate. The rotating impeller blade 15-3 cuts the high-pressure gas, generating a pulse force on the wind plate 12-2, which is conducive to the rice seeds falling. The DC air pump 13 is used to provide air power, which blows the wind plate 12-2 to rotate through the branch pipe 15 to make the rice seeds fall. The falling rice seeds fall into the air pipe 14, and are blown into the discharge pipe 16 by the air pipe 14 to be evenly sprayed.

[0032] like Figure 7 As shown, a valve 15-1 is provided on the branch pipe 15, and the valve 15-1 is used to adjust its size until a suitable rice seed falling speed is obtained.

[0033] After planting in planting block 3, loach fry can be released, with a stocking capacity of about 20,000 loaches / mu (body length 5 cm). After 1 week, bean cake, earthworms, bean dregs, bran and other baits can be appropriately fed, and the completion shall be completed within 3 hours. If no bait is fed, the stocking capacity shall be controlled at about 8,000 to 10,000 loaches. The breeding cycle is about 3-4 months, and the capture is after the rice harvest. If the loach does not meet the market specifications when the rice is harvested, the water level is deepened to about 20 cm after the harvest to continue breeding. When catching loaches, drain the field water, and the loaches gather in the loach nests under the planting blocks. At this time, uncover the planting blocks and use a sea scoop to catch the loaches. Rice is harvested manually or mechanically. During mechanical harvesting, the harvester tracks should not run over the planting blocks. Therefore, when setting the planting blocks, they should be away from the ridges to facilitate the harvester to turn around. The row spacing of the planting blocks should also meet the operating conditions that the tracks on both sides of the harvester do not run over the planting blocks.

[0034] Example 1

[0035] There are 4 rice fields with an area of ​​2 mu / mouth, and the water source and transportation conditions are good, so loaches can be raised in the rice fields. Rice and loaches can be raised according to the technical scheme of the rice-loach co-cultivation breeding device of the present invention.

[0036] Rice planting: including planting blocks and seed throwing. After the rice field is leveled, planting blocks are set up. The planting blocks are floating materials for planting rice. The area of ​​the planting blocks is determined according to the stocking amount of loaches. A planting block of 1 square meter is equipped for every 200 loaches or so. The planting blocks are rectangular and about 50 centimeters wide. The distance between each planting block is set at 1.5 meters to ensure that the tracks of the harvester do not crush the planting blocks during harvesting. The planting blocks are kept more than 4 meters away from the ridge to ensure that the harvester does not crush the planting blocks when turning around. There are planting holes on the planting blocks for planting rice plants. There are holes on the planting blocks, which are fixed with fixed rods to ensure that the planting blocks cannot move horizontally and can only move up and down with the rise and fall of the water surface. After the planting blocks are set up, rice seeds are scattered in the rice field, and more are scattered near the planting blocks for transplanting to the planting blocks later. The rice seeds are scattered with a seeder,

[0037] Making loach nests: After the rice seeds are sprayed, when the seedlings grow to more than 15 cm, they are transplanted to the planting block 3, the water depth of the rice field 1 is kept at about 5 cm, and fertilizers that promote the root growth of the seedlings are applied. As the seedlings grow, the water level is gradually deepened to about 10 cm, part of the rice plant roots are rooted in the rice field, and part of the rice plant forms a root cluster between the planting block 3 and the rice field mud 6 around the rice plant, and a space rich in dissolved oxygen is formed between the root clusters under the planting board 3, which is suitable for loach to live and hide, i.e., the loach nest 5.

[0038] The organic pile 4 is set up as a small pile of organic matter evenly distributed in the rice field 1, with a diameter of about 25 cm and a height of about 10 cm. The organic pile 4 provides organic fertilizer for the rice 1 on the one hand, and directly and indirectly provides bait for the loach on the other hand. The setting time is when the seedlings are about 10 cm. The organic pile is piled with fermented chicken manure or fermented fertilizer of livestock and poultry. The organic pile promotes the reproduction and growth of aquatic animals and provides bait for the growth of loach. 300 kilograms of organic materials are piled for every 10,000 loach seedlings and no more than 600 kilograms per mu of rice field.

[0039] Stocking of loach fry and harvesting of rice loach: Loach fry can be stocked after planting in planting block 3, with a stocking capacity of 20,000 / mu (body length 5 cm). After 1 week, bean cake, earthworms, bean dregs, bran and other baits can be appropriately fed, and the process should be completed within 3 hours. The breeding cycle is about 3 months, and the capture is after the rice harvest. Loach cannot reach the market specifications when the rice is harvested. After the harvest, the water level is deepened to about 20 cm and the breeding is continued for 20 days. When catching loach, drain the field water, and the loach gathers in the loach nest under the planting block. At this time, uncover the planting block and use a scoop to catch the loach.

[0040] The survival rate of the four rice fields is over 95%, and the average yield of commercial loaches per mu is 385 jin (the average individual weight is over 10 grams). The rice yield has increased by 5% compared with the historical average during the same period. Taking loaches as an example, the commercial loach is 8 yuan per jin, and the output value of each mu of rice field has increased by more than 3,000 yuan, achieving significant ecological and economic benefits.

[0041] Example 2

[0042] There are 3 rice fields with an area of ​​4 mu / mouth, and the water source and transportation conditions are good, so loaches can be raised in the rice fields. Rice and loaches can be raised according to the technical scheme of the rice-loach co-cultivation breeding device of the present invention.

[0043] Rice planting: including planting blocks and seed throwing. After the rice field is leveled, planting blocks are set up. Planting blocks are floating materials for planting rice. The area of ​​the planting blocks is determined according to the stocking amount of loaches. A planting block of 1 square meter is equipped for every 200 loaches. The planting blocks are rectangular and about 60 cm wide. The distance between each planting block is set at 1.5 meters to ensure that the crawler of the harvester does not crush the planting blocks during harvesting. The planting blocks are kept more than 5 meters away from the ridge to ensure that the harvester does not crush the planting blocks when turning around. There are planting holes on the planting blocks for planting rice plants. There are holes on the planting blocks, which are fixed with fixed rods to ensure that the planting blocks cannot move horizontally and can only move up and down with the rise and fall of the water surface. After the planting blocks are set up, rice seeds are scattered in the rice field, and more are scattered near the planting blocks for transplanting to the planting blocks later. The rice seeds are scattered using a seeder.

[0044] Making loach nests: After the rice seeds are sprayed, transplant the seedlings to the planting blocks when they grow to 15 cm, keep the water depth of the rice field at about 5 cm, and apply fertilizers that promote the root growth of the seedlings. As the seedlings grow, gradually deepen the water level to about 10 cm. Part of the rice plant's roots are rooted in the rice field, and part of the roots form root clusters between the planting blocks and the bottom of the field around the rice plants. A space rich in dissolved oxygen is formed between the root clusters under the planting board, which is suitable for loach to live and hide, i.e. loach nest 5.

[0045] Organic pile setting: It is a small pile of organic matter evenly distributed in the rice field. The diameter of the small pile is about 25 cm and the height is about 10 cm. The organic pile provides organic fertilizer for rice on the one hand and directly and indirectly provides bait for loach on the other hand. It is set up when the seedlings are about 10 cm. The organic pile uses fermented livestock manure. The organic pile promotes the reproduction and growth of aquatic animals and provides bait for the growth of loach. About 300 kilograms are piled for every 10,000 loach seedlings.

[0046] Stocking of loach fry and harvesting of rice loach: Loach fry can be stocked after planting in planting block 3, with a stocking rate of 10,000 loach / mu (body length 4 cm), and a breeding cycle of 4 months, during which loach is not fed. Capture is after rice harvest, when loach reaches marketable specifications. After rice harvesting is completed, loach is harvested, and loach gathers in the loach nest under the planting block. At this time, the planting block is uncovered and loach is caught with a scoop.

[0047] The survival rate of the three rice fields is over 90%, and the average yield of commercial loaches per mu is 198 jin (the average individual weight is over 10 grams). The rice yield has increased by 5% compared with the historical average during the same period. Taking loaches as an example, the commercial loach is 8 yuan per jin, and the output value of each mu of rice field has increased by more than 1,580 yuan, achieving significant ecological and economic benefits.

[0048] In summary, although the present invention has been disclosed as above in terms of preferred embodiments, the above preferred embodiments are not intended to limit the present invention. A person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined in the claims.
