Description

Technical Field

[0001] The present invention relates to the field of land irrigation technology, and in particular to a method, device and preparation for improving the water conservation capacity of farmland. Background Art

[0002] The core content of green agricultural development is the green planting and breeding cycle. We should promote the green planting and breeding cycle and comprehensively implement the comprehensive resource utilization of agricultural waste, especially the harmless treatment and resource utilization of livestock and poultry manure, so as to give full play to its role in improving the water conservation function of farmland.

[0003] In farmland irrigation, the utilization of manure is usually done by manual watering and fertilization, or irrigation with transportation equipment, which is very laborious and increases the workload of the staff. At the same time, the use of water conservation agents is also usually done by manual sowing and then watering, which has low construction efficiency and high labor intensity. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to address the above-mentioned technical deficiencies and provide a method, device and preparation for improving the water conservation capacity of farmland, which can meet the irrigation needs of manure, water and water-soluble fertilizers, thereby eliminating the need for excessive manual participation, reducing labor intensity, and effectively improving the overall construction efficiency. At the same time, in conjunction with water conservation preparations, the water storage and moisture retention capacity of the land can be further improved.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is as follows:

[0006] A storage area, wherein a conveying pipeline is provided on the storage area, and a crushing piece is connected to the middle of the conveying pipeline;

[0007] A main pipeline, which is arranged horizontally below the ground surface and communicates with the upper part of the crushing element through a pipeline. A plurality of longitudinally arranged branch pipelines are provided at equal intervals along the length of the main pipeline, and each branch pipeline is provided with a water outlet valve;

[0008] A groove perpendicular to the branch pipeline is opened on the ground surface along the side area of ​​the branch pipeline for storing the water conservation agent.

[0009] Preferably, the crushing element includes a cylinder and a rotating shaft; a water outlet and a water inlet are respectively provided above and below the cylinder; both ends of the rotating shaft are rotatably connected to the cylinder and are respectively provided with two groups of rotating blades, and the two groups of rotating blades are staggered.

[0010] Preferably, a plurality of longitudinal knives are provided at the tail end along the rotation direction of the rotating blade.

[0011] Preferably, a fixing ring is provided on the cylinder at the horizontal position of the rotating blade, and a plurality of vertical plates are provided along the circumferential direction of the fixing ring.

[0012] Preferably, a triangular protrusion is provided on the side surface of the vertical plate.

[0013] Preferably, an axial flow fan blade is provided at the bottom end of the rotating shaft, and a retaining ring is provided at the water outlet of the cylinder.

[0014] Preferably, a guide plate is provided on the cylinder above the water inlet.

[0015] Preferably, the water outlet valve is rotatably connected to the branch pipe.

[0016] A water conservation preparation for a supplementary irrigation device for improving the water conservation capacity of farmland comprises the following steps:

[0017] S1. The preparation is prepared by weight, namely, 20-30 parts of crop straw, 30-40 parts of edible fungus husks, 5-15 parts of charcoal powder, 1-2 parts of enzyme bacteria, 1-2 parts of urea, 1-2 parts of diammonium phosphate, 1-3 parts of calcium magnesium phosphate fertilizer, 0.3-1 parts of zinc sulfate, 0.1-0.3 parts of borax, and 4.7-40.6 parts of coal gangue;

[0018] S2, crushing crop straw, edible fungus chaff and coal gangue respectively, and mixing them with carbon powder;

[0019] S3, dissolving urea, diammonium phosphate, calcium magnesium phosphate, zinc sulfate, and borax in 20 parts of water, and adding the above mixture;

[0020] S4. Dissolve the enzyme bacteria in another 20 parts of water, and evenly add the solution to the mixture prepared in the above step. After mixing, naturally compost and ferment. The fermentation temperature is controlled at 40-60°C. Fermentation is terminated after 5-8 days to form grayish white to grayish black flocs.

[0021] S5. After granulation by the granulator, the granules are dried to form a water conservation preparation, which is then added to the conveying pipeline or placed in a trench;

[0022] Preferably, the number of portions configured in step one is 20 parts of crop straw, 30 parts of edible fungus chaff, 7 parts of charcoal powder, 1.5 parts of enzyme bacteria, 1 part of urea, 2 parts of diammonium phosphate, 3 parts of calcium magnesium phosphate fertilizer, 0.3 part of zinc sulfate, 0.2 part of borax, and 35 parts of coal gangue powder.

[0023] Compared with the prior art, the present invention has the following advantages:

[0024] 1. The manure generated during the breeding process is stored in the storage area. When needed, it is extracted by the internal pump and sequentially passes through the main pipe, branch pipe and outlet valve to meet the irrigation needs of the farmland. No manual operation is required, which reduces labor intensity and improves construction efficiency.

[0025] 2. In order to avoid the presence of large objects in the manure and sewage, which may cause blockage in the pipeline, the crushing parts are used to mix and crush the manure, effectively ensuring the normal transportation of the entire pipeline and reducing the need for subsequent maintenance work;

[0026] 3. By opening grooves on the ground, it is convenient to irrigate crops. By opening grooves on the ground, it is convenient to irrigate crops, avoid manure and water conservation agents directly acting on the crops themselves, causing "burn" injuries, and at the same time increase the contact area with the ground and improve the penetration efficiency;

[0027] 4. Most of the formulation components are industrial waste or agricultural and forestry residues, which are in large stock, cheap and have low production costs, creating favorable conditions for large-scale application;

[0028] 5. After trenching, water conservation agents are irrigated through irrigation devices to improve work efficiency, significantly improve the physical and chemical properties of farmland soil, reduce soil bulk density, increase soil effective pore content, loosen the soil, increase the activity of beneficial soil microorganisms, and promote the formation of a healthy soil food chain;

[0029] 6. After fertilization, the preparation can effectively expand the soil's water storage capacity, significantly enhance the soil reservoir's ability to regulate natural precipitation, improve the utilization rate and efficiency of natural precipitation for crops, and prevent surface waterlogging and waterlogging in farmland. It can be widely used in the modern agricultural production process in the Northeast region, which is mainly characterized by black soil, chernozem, meadow soil, white pulp soil, dark brown soil, and brown soil;

[0030] 7. The design of the trench has changed from the traditional vertical top-down soil improvement to lateral horizontal two-way soil improvement, which shortens the behavior path, expands the contact area, speeds up the improvement speed, and promotes the increase of soil biological activity.

[0038] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present invention.

[0039] Example 1

[0040] Combine Figure 1-6 As shown, a supplementary irrigation device for improving the water conservation capacity of farmland includes: a storage area 1, a delivery pipeline 101 is provided on the storage area 1, and a crushing element 2 is connected to the middle of the delivery pipeline 101; a main pipeline 3, which is arranged horizontally below the ground surface and connected to the top of the crushing element 2 through a pipeline. A plurality of longitudinally arranged branch pipelines 301 are provided at equal intervals along the length of the main pipeline 3, and each branch pipeline 301 is provided with a water outlet valve 302; grooves 303 are provided on the ground surface along the side areas of the branch pipelines 301 and are perpendicular to the branch pipelines 301 for storing a water conservation agent. By adding the water conservation agent, the water storage and moisture conservation capacity of the land is effectively improved during irrigation.

[0041] Manure from storage area 1 enters the crushing element through the conveying pipe 101, is crushed by the crushing element, and is discharged through the outlet valve 302. This effectively avoids clogging of the branch pipe 301 during irrigation and fertilization. The grooves 303 opened on the ground avoid direct contact with crops, thereby improving infiltration efficiency.

[0042] Water-soluble fertilizers and water conservation agents can be added through the delivery pipeline 101 and irrigation can be completed by water flow, eliminating the need for manual labor, effectively improving work efficiency and reducing labor intensity; a rubber hose is connected to the water outlet valve 302 for easy irrigation;

[0043] Among them, in actual use, the use of manure varies in different growth periods of crops. During the transportation of manure, clean water can be added to the transportation pipeline 101 for dilution, thereby reducing the overall content and facilitating the absorption of crops. At the same time, the overall design can also be used for separate watering and irrigation. Specifically, control valves are installed at the outlet of the storage area 1 and on the transportation pipeline 101 for control.

[0044] Combine Figure 3 and Figure 4 As shown, the crushing member 2 includes a cylinder 201 and a rotating shaft 202; a water outlet 203 and a water inlet 204 are respectively provided at the top and bottom of the cylinder 201; both ends of the rotating shaft 202 are rotatably connected to the cylinder 201 and are respectively provided with two sets of rotating blades 4, and the two sets of rotating blades 4 are staggered; the rotating shaft 202 drives the rotating blades 4 to complete the crushing of feces and sewage, and at the same time, the water outlet 203 is at the top and the water inlet 204 is at the bottom. The liquid flows from the bottom to the top, which facilitates the crushing of the rotating blades 4. The staggered arrangement of the two sets of rotating blades 4 effectively ensures that the feces and sewage are fully crushed;

[0045] In a preferred embodiment, a plurality of longitudinal blades 401 are provided at the tail end along the rotation direction of the rotating blade 4 to increase the contact area with the feces and improve the crushing efficiency;

[0046] In a preferred embodiment, a fixing ring 402 is provided on the cylinder 201 at the horizontal position of the rotating blade 4, and a plurality of vertical plates 403 are provided along the circumference of the fixing ring 402. During the movement of the rotating blade 4, part of the water flow is pushed toward the inner wall of the cylinder 201 to diffuse and rotate, thereby causing the feces to contact and collide with the vertical plates 403, assisting in crushing;

[0047] In a preferred embodiment, a triangular protrusion 404 is provided on the side of the vertical plate 403. When objects in the feces come into contact with the protrusion 404, the triangular structure improves the crushing effect.

[0048] The preferred embodiment, combined with Figure 3 As shown, an axial flow fan blade 205 is provided at the bottom of the rotating shaft 202, and a retaining ring 206 is provided at the water outlet 203 of the cylinder 201. The axial flow fan blade 205 can increase the kinetic energy of the upward movement of the water flow, which is convenient for the rotating blade 4 to crush. The design of the retaining ring 206 effectively prevents the backflow collision after the water flow contacts the top of the cylinder 201, thereby facilitating the smooth flow of water.

[0049] In a preferred embodiment, a guide plate 207 is provided on the cylinder 201 above the water inlet 204 to guide the water and keep the water flowing vertically upward.

[0050] Combine Figure 5As shown, the outlet valve 302 and the branch pipe 301 are rotatably connected. A plurality of connecting rings are evenly spaced at the end of the branch pipe 301 and the outlet valve 302, and are rotatably connected together. A rubber pad is also placed in the connecting ring to effectively avoid water leakage. At the same time, a sealing gasket in contact with the connecting ring is also provided at the bottom to further improve the sealing effect and realize the rotation function of the outlet valve 302. By rotating the outlet valve 302, irrigation of each groove is facilitated.

[0107] Example 11

[0108] The formulation ratio is: 20 parts of crop straw, 30 parts of edible fungus waste, 7 parts of activated carbon, 1.5 parts of enzyme bacteria, 1 part of urea, 2 parts of diammonium phosphate, 3 parts of calcium magnesium phosphate fertilizer, 0.3 parts of zinc sulfate, 0.2 parts of borax, and 35 parts of coal gangue;

[0109] Example 12

[0110] The formulation ratio is: 25 parts of crop straw, 35 parts of edible fungus waste, 12 parts of activated carbon, 1.5 parts of enzyme bacteria, 1 part of urea, 2 parts of diammonium phosphate, 3 parts of calcium magnesium phosphate fertilizer, 0.3 parts of zinc sulfate, 0.2 parts of borax, and 20 parts of coal gangue;

[0111] Example 13

[0112] The formulation ratio is: 30 parts of crop straw, 40 parts of edible fungus waste, 15 parts of activated carbon, 1.5 parts of enzyme bacteria, 1 part of urea, 1 part of diammonium phosphate, 1 part of calcium magnesium phosphate fertilizer, 0.8 parts of zinc sulfate, 0.2 parts of borax, and 9.5 parts of coal gangue;

[0113] Common pig manure and chicken manure were selected as comparative examples 1 and 2, respectively, and commercially available fertilizer (general-purpose) was selected as comparative example 3.

[0114] The experimental land was dry and hard. After water was sprinkled, it accumulated or flowed on the land area and could not be absorbed. The composition was 10.7g / kg organic matter, 0.3g / kg total nitrogen, 0.75g / kg total phosphorus, 13.8g / kg total potassium, 4.6% porosity, and 2.13g / cm3 bulk density. 3 ;

[0115] From the perspective of cycle analysis, the present technical solution is to add the formulation by digging trenches, and the ingredients can be absorbed by the plant roots within 7-11 days, and the land improvement is completed in 5-7 weeks, while the comparative example 1 is absorbed by the plants in 15-30 days and the land is improved in 11-12 weeks, but the effect is not good, and the comparative example 2 is similar to the comparative example 1, and the comparative example 3 is absorbed by the plant roots in 12-20 days and improves the land in about 10 weeks, which also has a poor effect. In addition, the comparative examples 1 and 2 need to be used in combination with other fertilizer components, which is prone to imbalance of components.

[0116] At the same time, for the grooves 303, the experiment was carried out on the land under the same conditions as in Example 1. Compared with the traditional rotary tillage, the speed of returning the soil to the field by opening the grooves 303 was increased by 20-30%.

[0117] By comparison, we can see (see Appendix Figure 6 ), the formulation scheme of the present invention can effectively improve the water storage and moisture retention capacity and nutrient content of the land, and at the same time accelerate the time of soil improvement. The enzyme bacteria itself has the function of loosening the soil, and the edible fungus waste, coal gangue and activated carbon powder also have the function of loosening the soil, and are rich in organic matter, nitrogen, phosphorus, potassium and various trace elements. Therefore, they can also be used as culture medium base materials for enzyme bacteria, which can make the enzyme bacteria multiply and increase the enzyme bacteria per unit area of ​​farmland exponentially, thereby accelerating the loosening speed, expanding the loosening range and enhancing the loosening effect; at the same time After the edible fungus waste is fermented and decomposed by enzyme bacteria, organic matter that is easily absorbed by crops is produced. The organic matter also has the function of loosening the soil. The loosening range is 30-50 cm, the soil bulk density is reduced by 8.5%-11.5% compared with the control, the field water holding capacity is increased by 10-12% compared with the control, and the effective storage capacity of the 1-100cm soil reservoir is increased by 100-120mm compared with the control, thereby achieving the purpose of improving the utilization rate of farmland precipitation resources, and part of the components in the ingredients come from the recycling and reuse of waste, with low cost.

[0118] Example 14 (Specific Application Case)

[0119] (1) Regional layout

[0120] Taking 100 hectares (1000m x 1000m) of land as an example, 10 hectares (200m x 500m) of one corner are planned as a breeding area to raise 10,000 dairy cows; the remaining 90 hectares are planned as a planting area to grow soybeans.

[0121] (2) Strip trenching and straw backfilling in the planting area

[0122] The soybean planting time is around May 1st, and the strip trenching time is in early June. The crop height is about 30 cm, and the trenching and ridge-making will not cause crop landfill; the trench 303 is 3 meters apart, 50 cm deep, and 8 cm wide, with a total trench length of 300,000 meters; the straw backfilled in the trench is chopped straw with a length of about 5 cm, and the backfill amount per extended meter is 5 jin.

[0123] (3) Manure treatment and liquid fertilizer collection in breeding areas

[0124] At the edge of the breeding area, close to the planting area, an underground sewage collection tank (length, width and depth of 20 meters, 15 meters and 4 meters), three underground anaerobic biogas fermentation tanks (length, width and depth of 20 meters, 5 meters and 4 meters), and an underground fertilizer and water storage tank (length, width and depth of 20 meters, 15 meters and 4 meters) are built to form storage area 1, which is used for collecting manure, anaerobic fermentation and storing fertilizer and water.

[0125] (4) Fertilizer and water distribution and furrow irrigation

[0126] An underground pipe network is constructed between the breeding area and the planting area, as well as within the planting area. It consists of a main pipe 3 with a diameter of 160 mm and a branch pipe 301 with a diameter of 110 mm. In the breeding area, a pressure pump is used to inject fertilizer water from the storage area 1 into the inlet of the underground pressurized pipe. The upper pressure limit of the underground pressurized pipe is set at 3 atmospheres (30 meters of water head), and the pressure return difference is 1 atmosphere. That is, when the pressure in the underground pressurized pipe exceeds 3 atmospheres, the pressure pump immediately stops working. When it drops to 2 atmospheres, it starts again and circulates in sequence. In the planting area, the outlet valve 302 connected to the branch pipe 301 is opened, and a hose is connected to irrigate the groove 303. The amount of fertilizer water irrigation per extended meter is 50 liters, and the irrigation cycle is 7 days.

[0127] Example 15

[0128] Combined with the device to optimize the fertilization of water conservation preparations;

[0129] The water conservation agent is pre-arranged in the groove 303, or directly stored in the storage area 1. When in use, the storage area 1 is pressurized by the water pump and the liquid is transferred to the main line 3 and the branch line 301 through the delivery pipeline. The liquid is then sprayed out by the water outlet valve 302 to meet the irrigation needs. Among them, by adding the water conservation agent to the storage area 1, irrigation and fertilization are facilitated and the operation efficiency is improved.
