Description

Technical Field

[0001] The invention relates to the technical field of rice planting, in particular to a method for planting organic rice. Background Art

[0002] Organic rice is a general term for grains such as japonica and glutinous rice of the herbaceous rice genus Oryza. Rice generally refers to the general term for crops that need to be planted in paddy fields, while rice in the herbal book refers specifically to glutinous rice. The word "rice" is transformed from the word "scoop", and the original meaning of "scoop" is exactly a person pounding rice on a stone mortar. Rice is an annual plant of the Poaceae family, a monocotyledon, and likes warmth and humidity. It is about 1 to 1.8 meters tall when mature, with slender leaves, about 50 to 100 centimeters long and 2 to 2.5 centimeters wide. The flowers of rice are very small. When blooming, the main flower branches will be arched, and small flowers will bloom 30 to 50 centimeters below the branches. Most of them are self-pollinated and produce seeds, called rice ears, which are generally 5 to 12 mm long and 2 to 3 mm thick.

[0003] Rice-duck farming is an ecological agricultural model that combines rice and ducks to form an interdependent growth model. In this model, ducks move around in rice fields and eat weeds and pests in the rice fields through their omnivorous nature. At the same time, their activities can stimulate the growth of rice, play the role of tillage and muddy water, promote soil permeability and nutrient circulation, and duck manure becomes a natural fertilizer for rice growth, which not only improves rice yield and quality, but also reduces the use of chemical fertilizers and pesticides, and realizes green and sustainable agricultural production. However, in the process of rice-duck farming, duck manure cannot meet the needs of rice, and the mobility of ducks will carry pests, causing the spread of rice diseases and pests. Therefore, as to whether rice-duck farming can achieve a good ecological agricultural model, the planting method of organic rice and the field management of ducks are key technologies, and this application is proposed for this purpose. Summary of the invention

[0004] The object of the present invention is to provide an organic rice planting method to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions: An organic rice planting method includes the construction of rice fields and duck houses, the selection of rice, and the selection and domestication of duck breeds, including the following steps: S1: Construction of rice fields. A protective net is set up outside the rice fields to prevent ducks from escaping. Inlet and main channels are dug outside the rice fields for water inlet and outlet. A hot spring pool is set up between the rice fields and the duck house. S2: Domestication of ducklings. Before feeding, the ducklings are tapped on the iron basin or other methods to attract their attention, and then they are fed and domesticated. When they hear the sound of tapping the iron basin or other methods after being put in, they can move to the duck house to gather, which is convenient for the later management of the duck group, including weeding and domestication of ducklings in rice fields; S3: Construction of the duck house. The outer perimeter of the duck house is equipped with a fence to prevent the ducks from escaping. The fence extends to the protective net and is connected to the protective net. The ducks can enter the rice field from the duck house without escaping. There is a gate on the fence for the breeder to enter and clean the duck house. S4: Field management. Seven to ten days after rice is planted, the domesticated ducklings are placed in the rice fields all day long. Organic fertilizers are applied according to the nutrient requirements of rice and the amount of duck excretion, including base fertilizer, tillering fertilizer, ear fertilizer and grain fertilizer stages. Ducks are stopped from entering the rice fields before the ears emerge from the tunnels. During this period, the weight of the ducks generally does not exceed 7kg.

[0006] As a further solution of the present invention: the protective net of each rice field is independent, and the rice fields are managed in a modular manner through the protective net, so that the ducks work in the rice fields in a cyclical manner, and the length of the operation cycle of each rice field is adjusted according to the conditions of the grass plants in the rice fields.

[0007] As a further solution of the present invention: a drainage channel is also provided on one side of the large channel, the large channel is connected to the water inlet channel through a cement pipe, and a sluice is provided. The drainage channel is provided on one side of the rice field, and a gate for controlling the discharge of water from the rice field is provided on the ridge between the drainage channel and the rice field.

[0008] As a further solution of the present invention: disinfectant is injected into the hot spring pool, the depth of the hot spring pool is between 30-40 cm, the depth of the disinfectant is between 15-25 cm, slopes are set on both sides of the hot spring pool, the slope is 3-6%, and waterproof coating and waterproof cloth are laid on the bottom of the hot spring pool.

[0009] As a further solution of the present invention: the disinfectant is lime water, and the concentration of the lime water disinfection is 10%-15%.

[0010] As a further solution of the present invention: the water level of the disinfectant rises with the height of the duck, and the water level change is observed daily. The water level height generally does not exceed the height of the duck, so as to avoid the duck from drowning and replenish and replace the disinfectant in time.

[0011] As a further solution of the present invention: a high ridge is provided between the rice field and the hot spring pool. The height of the high ridge is higher than the height of the rice and the width is greater than ten meters. This allows the movement of agricultural machinery while the ducks come out of the disinfectant and walk on the high ridge. This provides the ducks with enough time to air dry and shake off the residual disinfectant on their feathers, thus avoiding bringing a large amount of disinfectant into the rice field.

[0012] As a further solution of the present invention: a protective net is set up on the high ridge to guide the ducks to the designated rice fields for operation.

[0013] As a further solution of the present invention: a manure discharge net is laid at the bottom of the duck house, a manure collection channel is dug at the bottom of the manure discharge net, one end of the manure collection channel is connected to a water source, and the other end is connected to a large channel, and sluices are provided at both ends of the manure collection channel.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. This organic rice planting method improves the domestication degree of ducklings through the domestication model of ducklings, making it easier to call ducks in the field. It also provides convenience for modular rice fields and ducks to work periodically in the rice fields, thereby optimizing the field management of rice-duck farming.

[0015] 2. In this organic rice planting method, the protective net separates the rice fields to form multiple modules. When entering the next rice field for operation, the protective net is adjusted to surround the rice field where the operation has been completed, and the protective net of the next rice field is opened for manual guidance.

[0016] 3. This organic rice cultivation method reduces the transmission of pests and diseases and improves the health of ducks by setting up hot springs and laying protective nets around rice fields.

[0017] 4. This organic rice planting method can more accurately control the amount of fertilizer and topdressing according to the changes in the amount of feces of ducks at different ages and the needs of different fertilization cycles of rice, avoid over-fertilization and insufficient fertilization, and better realize rice-duck farming.

[0020] See also Figure 1 In an embodiment of the present invention, an organic rice planting method includes the construction of a rice field 1 and a duck house 5, the selection of rice, and the selection and domestication of duck species, including the following steps; S1: Construction of rice field 1. A protective net 8 is set up around the field of rice field 1 to prevent ducks from escaping. An inlet channel 2 and a large channel 9 for water inlet and outlet are dug outside the rice field 1. A hot spring pool 4 is set between the rice field 1 and the duck house 5. Disinfectant is injected into the hot spring pool 4. The depth of the hot spring pool 4 is between 30-40 cm, and the depth of the disinfectant is between 15-25 cm. Slopes are set on both sides of the hot spring pool 4 with a slope of 3-6%. Waterproof coating and waterproof cloth are laid on the bottom of the hot spring pool 4. Inlet and outlet pipes are set on both sides of the hot spring pool 4 for replenishing, circulating and replacing the disinfectant. Normally, the disinfectant in the hot spring pool 4 is flowing and circulating to reduce the precipitation of the disinfectant. 4 is equipped with a disinfectant mixing device, which is mainly composed of a stirring kettle and a circulating pump. The disinfectant is mixed in the stirring kettle and then pumped into the hot spring pool 4 through the circulating pump. The pipeline is controlled by a valve, and the disinfectant in the hot spring pool 4 is circulated by the circulating pump. After the ducks enter, the water level will rise. The height difference between the hot spring pool 4 and the disinfectant can not only prevent the disinfectant from overflowing the hot spring pool 4, but also enable the disinfectant brought out by the ducks when they go ashore to flow back into the hot spring pool 4 to reduce loss. The slope of 3-6% is convenient for the ducks to climb ashore. The waterproof coating and the waterproof cloth form a waterproof layer to prevent the disinfectant from seeping into the ground. The waterproof coating and the waterproof cloth are arranged in the waterproof layer of the fish pond.

[0021] The disinfectant is lime water, and the concentration of lime water disinfection is 10%-15%. As a disinfectant, the concentration of lime water is crucial to the disinfection effect. According to relevant data, 10% lime water is widely used for disinfection purposes. This concentration can effectively kill bacteria, including common reproductive bacteria and some specific pathogens. The main function of lime water is to kill bacteria, rather than directly kill pests or eggs carried by duck feathers. Therefore, it is more regarded as an auxiliary means, used in combination with other insecticides or methods to achieve better prevention and control effects, and does not act directly on crops.

[0022] The water level of the disinfectant rises with the height of the duck. Observe the water level changes every day. The water level generally does not exceed the height of the duck to prevent the duck from drowning. Replenish and replace the disinfectant in time. The disinfectant can not only prevent pests or insect eggs carried by the duck, but also provide protection for the health of the duck and kill bacteria. The water level change of the disinfectant is proportional to the height of the duck.

[0023] A high ridge 3 is also set between the rice field 1 and the hot spring pool 4. The height of the high ridge 3 is higher than the height of the rice and the width is more than ten meters. It can meet the movement of agricultural machinery. At the same time, the ducks come out of the disinfectant and walk on the high ridge 3. They have enough time to air dry and shake off the residual disinfectant on their feathers to avoid bringing a large amount of disinfectant into the rice field 1. Adding lime to the rice field, whether it is to adjust the soil acidity, improve the soil structure or deal with heavy metal pollution in the soil, involves the intervention of chemical substances, which is contrary to the principles of organic farming. Therefore, when the lime passes through the high ridge 3, it either detaches from the feathers or is air-dried to minimize the lime water entering the rice field 1. After passing the high ridge 3, the lime water carried by the ducks is very small and can be ignored.

[0024] A protective net 8 is set up on the high ridge 3 to guide the ducks to the designated rice field 1 for operation; S2: domestication of ducklings. Before feeding, the ducklings are attracted by knocking on the iron basin or other methods, and then fed and domesticated. When the ducklings hear the sound of knocking on the iron basin or other methods after being put in, they can move to the duck house 5 to gather, which is convenient for the later management of the duck group, including weeding and domestication of the ducklings in the rice field 1. During the duckling hatching and rearing stage, the ducklings are domesticated by knocking on the iron basin or other methods to achieve conditioned reflex. After being domesticated for 1-2 months, they are guided to the field for weeding and domestication; S3: Construction of duck house 5. The outer periphery of duck house 5 is provided with guardrail 6 to prevent ducks from escaping. Guardrail 6 extends to and is connected to guardrail 8. Ducks can enter rice field 1 from duck house 5 without escaping. Guardrail 6 is provided with gate for breeders to enter and clean duck house 5. Guardrail 8 of each rice field 1 is independent. Rice field 1 is managed in modular mode through guardrail 8, so that ducks can work in rice field 1 according to cycle. The length of operation cycle of each rice field 1 is adjusted according to the grass plant conditions in rice field 1. Ducks Every day, when the sound of knocking on the iron basin or other methods is made, the ducks will pass through the hot spring 4 for sterilization. When entering the next rice field 1 for weeding, it can avoid bringing pests and diseases in the previous rice field 1 into the next rice field 1. The rice field 1 is managed modularly to reduce the transmission path of pests and diseases. The height of the protective net 8 is 0.6 meters to 1 meter. One module is enclosed for every 1-2 mu. The protective net is made of plastic woven net with mesh sizes of 14 mesh, 16 mesh, 18 mesh, 20 mesh, and 32 mesh to prevent the spread of rice leafhoppers according to needs; S4: Field management: Seven to ten days after rice planting, the domesticated ducklings are placed in the rice field all day long1. Organic fertilizers are applied reasonably according to the nutrient requirements of rice and the amount of duck excretion, including base fertilizer, tillering fertilizer, ear fertilizer and grain fertilizer stages. The ducks are stopped from entering the rice field before the ears emerge from the tunnel1. During this period, the weight of the ducks generally does not exceed 7kg; From this, we can know the amount of ducks' excrement in each cycle, and selectively release an appropriate number of ducks, generally 20 ducks per mu, and apply appropriate topdressing according to the amount of excrement. Types of organic fertilizers: organic fertilizers are combined with compound fertilizers, including mature fermented biogas slurry, composted livestock manure or commercial organic fertilizers with organic matter ≥30 and total nutrients ≥4. Organic fertilizers include fresh green manure, stable manure, dry straw, etc. Dosage: According to the guidance plans of different regions, the amount of organic fertilizers varies. Generally speaking, 60-100 kg of commercial organic fertilizers are applied per mu, or about 250 kg of grass per mu is appropriate. All organic fertilizers and phosphate fertilizers in the base fertilizer are applied, and topdressing is applied in time according to the growth of crops; ‌Application period and method‌: ‌Base fertilizer‌: All organic fertilizers and phosphate fertilizers are applied as base fertilizers and applied to the soil before plowing or transplanting.

[0025] Top dressing: Top dressing should be applied in two times. The first time should be applied about 7 days after transplanting, and the second time should be applied about 15 days after transplanting. Top dressing should be mainly nitrogen fertilizer with an appropriate amount of potassium fertilizer.

[0026] ‌Ear fertilizer‌: During the panicle differentiation period, about 25 days after transplanting early rice and 50 days after transplanting late rice, if the leaves turn yellow, apply an appropriate amount of ear fertilizer.

[0027] Foliar spraying: Spray potassium dihydrogen phosphate or rice foliar fertilizer during the booting stage and maturity stage to improve the stress resistance of rice and promote grain filling and development.

[0028] In summary, the fertilization parameters of organic fertilizers for organic rice involve many aspects such as fertilizer type, dosage, application period and method. They need to be flexibly adjusted according to specific soil conditions, climatic conditions and crop growth conditions, and the amount of duck excrement should be taken into account to avoid over-fertilization and under-fertilization.

[0029] In a preferred embodiment, a drainage channel 10 is also provided on one side of the main channel 9. The main channel 9 is connected to the water inlet channel 2 through a cement pipe 11, and a sluice is provided. The drainage channel 10 is provided on one side of the rice field 1, and a gate 12 for controlling the discharge of water from the rice field 1 is provided on the ridge between the drainage channel 10 and the rice field 1. The water in the main channel 9 enters the water inlet channel 2 through the cement pipe 11, enters the rice field 1 through the water inlet channel 2, and is discharged from the gate 12 into the drainage channel 10 for one cycle.

[0030] In a preferred embodiment, a manure discharge net is laid at the bottom of the duck house 5, and a manure collection channel 7 is dug at the bottom of the manure discharge net. One end of the manure collection channel 7 is connected to a water source, and the other end is connected to a large channel 9. Both ends of the manure collection channel 7 are provided with sluice gates. The feces discharged by the ducks when they roost in the duck house 5 are accumulated in the manure collection channel 7 through the manure discharge net. During the rice field fertilization cycle, the feces in the manure collection channel 7 are flushed away through the water source, merged into the large channel 9, and distributed to the rice field 1 as organic fertilizer.

[0031] It should be noted that the above embodiments all belong to the same inventive concept, and the description of each embodiment has its own focus. For matters that are not described in detail in some embodiments, reference may be made to the description in other embodiments.

[0032] The above-mentioned embodiments only express the implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
