Description

Technical Field

[0001] The invention relates to the technical field of ecological breeding and cultivation, and in particular to a three-dimensional breeding and cultivation method of rice frogs and snails in a ditch type. Background Art

[0002] In the rice-frog symbiotic breeding model, in order to facilitate management and improve feed utilization, the community is often divided and managed. Each breeding community is equipped with a ring ditch, and a feeding area is set up outside the ring ditch. This model greatly compresses the rice planting area, making the ditch area account for a much higher proportion than the requirements of the Ministry of Agriculture and Rural Affairs' "Technical Specifications for Integrated Rice-Fish Breeding" (Part 1: General Principles). Secondly, the traditional rice-frog symbiotic breeding method lacks effective space utilization and food feeding mechanisms. The feed utilization rate is only about 30%, which can easily lead to a poor production environment, and there is a risk of excessive pesticide residues in frogs and agricultural non-point source pollution. The breeding efficiency and food utilization rate are not ideal.

[0003] Chinese patent CN 115735692 A discloses a rice-frog co-cultivation technology for improving quality and efficiency. The technology digs frog ditches and frog banks around the planting field to breed frogs, which greatly occupies the planting area of ​​crops. Moreover, the technology only uses pests to breed frogs, resulting in a lack of bait. Even if the frog ditches around the frogs are regularly fed, the utilization rate of the bait is still low. Therefore, this technology is actually difficult to achieve a win-win situation in planting and breeding. Summary of the invention

[0004] The purpose of the present invention is to provide a three-dimensional cultivation method of rice frog snails in a ditch type, so as to solve the problems of insufficient utilization of farmland resources and low utilization rate of food feeding in the prior art.

[0005] In order to solve the above technical problems, the present invention adopts the following technical scheme, a three-dimensional cultivation method of rice frogs and snails in trenches: a plurality of trenches are arranged at intervals in the farmland to divide the farmland into a plurality of crop areas, the total area of ​​all trenches accounts for no more than 10% of the total area of ​​the farmland, a plurality of feeding tables are arranged above each trench and food is regularly placed on the feeding tables, a protective net is laid around the farmland and frogs are placed in the farmland for breeding.

[0006] Preferably, multiple furrows are arranged in parallel and evenly in the farmland, so that the crop areas are distributed at even intervals, increasing the ventilation and light transmittance of the farmland, thereby reducing the incidence of animal and plant diseases and increasing the marginal effect of crops.

[0007] More preferably, the ditch and the crop area are both rectangular structures, the ditch has a width of 0.4 m and a depth of 0.4 m, and the crop area has a width of 4 m.

[0008] More preferably, the feeding table comprises an elastic net laid on the compartment ditch, and when the frog jumps onto the elastic net, the food can be bounced up by rebounding effect, so as to facilitate the frog to catch food.

[0009] More preferably, snails are also cultured in the ditch, and the mesh size of the elastic net allows fine particles in the food to fall into the ditch below so that the snails can eat it. The mesh size of the elastic net is 0.85 mm.

[0010] More preferably, the elastic net is surrounded by sealing edges that can be erected on the upper edge of the ditch, and the outer side of the sealing edge is provided with a slope surface that is convenient for the frog to climb up.

[0011] More preferably, a limiting rod is provided on the bottom surface of each corner of the edge of the elastic net, and a limiting hole for inserting the limiting rod downward is opened in the corresponding farmland, and a sealing structure is also provided between the limiting rod and the limiting hole. A plurality of floating blocks are provided on the bottom surface of the elastic net. When the water surface in the field is higher than the box surface, the elastic net can float on the water surface through the buoyancy of the floating blocks. At this time, part of the rod body of the limiting rod is still in the limiting hole to prevent the elastic net from drifting away from its original position.

[0012] More preferably, a light-controlled lighting lamp is installed on one side of the feeding table, and the lighting lamp is used to turn on when the light is dim to tame the feeding, and the limiting rod on the other side of the feeding table is filled with counterweight contents to balance the weight of the lighting lamp.

[0013] Compared with the prior art, the invention has the following innovative features and beneficial effects:

[0014] First, the furrow cultivation model is used to increase the marginal effect of rice. When the rice planting area is reduced (<10%), the rice yield does not decrease compared with conventional rice cultivation, and increases by 64.75% compared with rice frog cultivation. In addition, it increases the ventilation and light transmittance of farmland, enhances the photosynthetic efficiency of rice, and reduces the occurrence of diseases.

[0015] Second, establish a three-dimensional breeding structure of frogs and snails. Taking advantage of the complementary role of snails and frogs in ecological niches, snails feed on frog bait and feces, and do not need additional feeding. This has the advantages of enhancing the nutrient turnover rate in the field, strengthening the flow and expanding the reservoir; avoiding the accumulation of bait to deteriorate the production environment, reducing the occurrence of frog diseases, and increasing the frog survival rate by 26.33%; reducing the total nitrogen content of tailwater discharge by 67.55% and the total phosphorus content by 36.84%, and reducing the risk of agricultural non-point source pollution.

[0016] Third, optimize the structure of the frog feeding platform. Make full use of the ditch space and eliminate the farmland area occupied by the feeding platform in the traditional rice-frog model. The optimized feeding platform has advantages that traditional feeding platforms do not have, such as saving space, light source inducing feeding, light source attracting insects, and adapting to multiple production scenarios. The bait utilization rate is increased by 66.79%.

[0017] Fourth, it reduces production expenditure and improves production income. Compared with the conventional rice-frog symbiosis model, the method of the present invention can not only significantly increase the rice yield and frog yield, but also increase the snail yield, while reducing the costs of feed, labor, veterinary drugs, etc., and the benefits are outstanding.

[0024] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0025] It should be noted in advance that, in the present invention, unless otherwise clearly specified and limited, the terms such as "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances. In addition, in the present invention, unless otherwise clearly specified and limited, the first feature "on" or "under" the second feature may include the first and second features being in direct contact, and may also include the first and second features not being in direct contact but being in contact through another feature between them.

[0026] like Figure 1 to Figure 2 As shown, a three-dimensional cultivation method of rice frogs and snails in ditch type is provided: a plurality of ditches 1 are arranged at intervals in the farmland to divide the farmland into a plurality of crop areas 2, the total area of ​​all the ditches 1 accounts for no more than 10% of the total area of ​​the farmland, a plurality of feeding tables 3 are arranged above each ditch 1 and food is regularly placed on the feeding tables 3, a protective net is laid above and around the farmland and frogs are placed in the farmland for breeding.

[0027] Furthermore, multiple furrows 1 are arranged in parallel and evenly in the farmland, so that the crop areas 2 are distributed in a uniformly spaced manner, so as to increase the ventilation and light transmittance of the farmland, reduce the occurrence of diseases, and increase the marginal effect area of ​​rice, thereby making up for the rice production area occupied by the furrow area.

[0028] In this embodiment, the ditch 1 and the crop area 2 are both rectangular structures, and the width of the ditch 1 is 0.4m. Preferably, the width of the crop area is 4m, which is convenient for agricultural machinery operations, and the depth of the ditch is 0.4m, which can not only ensure the water area for frog activities, but also match the existing ditching machinery. The rectangular structure design of the ditch 1 and the crop area 2, as well as the reasonable ratio of the width of the ditch to the width of the crop area, make the farmland layout more standardized and easy to manage and maintain.

[0029] As for the specific structure of the feeding table 3, the feeding table 3 includes an elastic net laid on the side ditch 1. When the frog jumps on the elastic net, the food can be bounced up by the rebound effect, so as to facilitate the frog to catch food, thereby improving the feeding efficiency and breeding efficiency. In addition, an edge sealing structure is provided around the elastic net to maintain the stability of the feeding table 3, and at the same time, the bottom end of the edge sealing can have a certain thickness, so as to facilitate the elastic net to be erected on the side ditch 1. In addition, the outer side of the edge sealing is provided with a slope surface for frogs to climb up. Since the newly metamorphosed frogs cannot jump for the time being and can only crawl, the provision of a slope surface helps these frogs to easily climb onto the elastic net for catching food.

[0030] In order to further utilize breeding resources and space, snails are also cultured in the ditch 1. The mesh size of the elastic net (for example, it can be 0.85mm) allows fine particles in the food to fall into the ditch 1 below so that the snails can eat it, thereby effectively utilizing food residues, forming an ecological symbiotic system, and improving the material recycling rate.

[0031] Those skilled in the art should know that the water level in the farmland during the heading and filling periods will rise. In order to avoid the feeding platform 3 being flooded and unable to feed, Figure 3 As shown, the bottom surface of each corner of the edge of the elastic net is provided with a limit rod 4, and the farmland is provided with a limit hole for the limit rod 4 to be inserted downward. A sealing structure is also provided between the limit rod 4 and the limit hole. The bottom surface of the elastic net is provided with a plurality of floating blocks 5. When the water surface in the field is higher than the surface of the box, the elastic net can float on the water surface through the buoyancy of the floating blocks 5. At this time, part of the rod body of the limit rod 4 is still in the limit hole to prevent the elastic net from drifting away from the original position. In practical applications, the floating blocks 5 can be set on both side edges of the bottom surface of the elastic net to reduce their obstruction to the mesh.

[0032] In addition, a light-controlled illuminator 6 is installed on one side of the feeding platform, and the illuminator 6 is used to turn on when the light is dim to tame and feed the frogs. The limit rod 4 on the other side of the feeding platform is filled with a counterweight content to balance the weight of the illuminator 6. The phototaxis of frogs is utilized to attract them to the feeding platform, thereby cultivating the feeding habits of frogs, which can effectively improve the feeding efficiency at night or in an environment with insufficient light. Moreover, since insects have phototaxis, the feeding platform can be used as a natural foraging ground for frogs at night. In the present embodiment, the illuminator 6 adopts a solar energy-saving illuminator to achieve energy-saving effects.

[0033] The specific implementation process of the above-mentioned three-dimensional cultivation method of rice frog snails in the ditch type is as follows:

[0034] 1. Farmland Preparation

[0035] Ditch digging: Multiple trenches 1 are dug at equal intervals in the farmland. The trenches 1 are parallel and evenly distributed, and the farmland is divided into multiple rectangular crop areas 2. The width of the trench 1 is set to 0.4 meters, and the width of the crop area 2 is set to 4 meters to ensure the convenience of agricultural machinery operation. Ensure that the total area of ​​all trenches 1 does not exceed 10% of the total area of ​​the farmland.

[0036] Laying of protective nets: Lay protective nets above and around farmland to prevent frogs from escaping and natural enemies from invading.

[0037] 2. Feeding table construction

[0038] Feeding table structure: A feeding table 3 is built above each ditch 1, and the feeding table 3 includes an elastic net laid on the ditch 1. The mesh size of the elastic net is set to 0.85mm, allowing fine particles in the food to fall into the ditch 1 below for the snails to eat.

[0039] Limiting rod and floating block setting: A limiting rod 4 is set on the bottom surface of each corner of the elastic net edge, and a limiting hole for the limiting rod 4 to be inserted downward is opened in the farmland. A sealing structure is set between the limiting rod 4 and the limiting hole, and a plurality of floating blocks 5 are set on the bottom surface of the elastic net to adapt to the change of water surface height in the field.

[0040] 3. Breeding Implementation

[0041] Frog release: Select frog species suitable for breeding and release them into farmland for breeding.

[0042] Irrigation and drainage management: Regularly check the irrigation and drainage conditions of the farmland to ensure appropriate moisture conditions in the farmland.

[0043] Feeding plan: According to the growth habits of frogs, formulate a reasonable feeding plan to achieve "time, location, quality and quantity". Put 5% to 8% of the frog's weight of food on the feeding table 3, and use the rebound effect of the elastic net to help the frog catch food.

[0044] Snail farming: snails are farmed in the ditch 1 at the same time, and the food residues dropped into the ditch 1 are used as the food source for the snails.

[0045] 4. Ecological Symbiosis System

[0046] Material recycling: By raising snails and frogs together, an ecological symbiotic system is established. Snails feed on frog bait and feces, so no additional feeding is needed, which enhances the nutrient turnover rate in the field.

[0047] Environmental optimization: reduce the accumulation of bait that deteriorates the production environment, reduce the occurrence of frog diseases, and improve the survival rate of frogs.

[0048] V. Costs and Benefits

[0049] Cost control: Reduce the cost of feed, labor, veterinary drugs, etc. by optimizing the feeding table structure and improving bait utilization.

[0050] Improved benefits: Greatly increased rice and frog yields, increased snail yields, and achieved outstanding benefits.

[0051] 6. Additional Facilities

[0052] Lighting installation: A light-controlled lighting lamp 6 is installed on one side of the feeding table, which is used to turn on when the light is dim to tame and feed the frogs, and utilize the phototaxis of frogs to attract them to the feeding table, thereby improving feeding efficiency.

[0053] Counterweight balance: The limiting rod 4 on the other side of the feeding table is filled with counterweight contents to balance the weight of the lighting lamp 6.

[0054] In order to reflect the effects of the cultivation and breeding method of the present invention, conventional rice planting and traditional rice frog cultivation and breeding modes were used as comparative examples to compare the output with the production mode provided in the above embodiment. The results are shown in Table 1 below.
