Description

Technical Field

[0001] The invention belongs to the technical field of agricultural fertilization and infiltration irrigation, and specifically relates to a fertilizer belt capable of accurately fertilizing and an infiltration irrigation system used in conjunction with the fertilizer belt. Background Art

[0002] Traditional fertilization methods can be roughly divided into two types. One is the application of solid fertilizers, which can be applied by spreading on the ground, sowing in holes, or shallowly burying. There is also a method of pre-burying base fertilizers before planting crops. The other is the application of liquid fertilizers, which is generally applied by mixing with irrigation water. The above two types of fertilizers are applied by dissolving the fertilizers in irrigation water for absorption and utilization by the roots of crops. The existing irrigation methods are matched with the existing fertilizers, that is, whether it is flooding, sprinkler irrigation or drip irrigation, the irrigation water infiltration area matches the preset fertilizer area, so that the preset fertilizer can be fully dissolved and utilized.

[0003] However, in some areas with extreme water shortage, the above irrigation method cannot meet the requirements of the ecological environment for water-saving irrigation, and a more water-saving infiltration irrigation method is needed for crop irrigation. The reason why infiltration irrigation is more water-saving is that its water infiltration head is buried near the roots of crops underground, and its water output is quantitatively infiltrated according to the growth needs of crops. Since the amount of infiltrated water is limited, the soil that can be infiltrated is also extremely limited. Therefore, if the infiltration irrigation system is still fertilized according to the traditional fertilization method, most of the fertilizer cannot be absorbed and utilized by crops because it cannot be moistened and dissolved by water. In this way, in the extremely water-saving infiltration irrigation system, the traditional fertilization method will not only cause ineffective application and waste of fertilizers, but also affect the growth of crops due to insufficient absorption of fertilizer nutrients.

[0004] Therefore, how to provide a product and method that can achieve precise fertilization under an infiltration irrigation system is an urgent problem that technicians in this field need to solve. Summary of the invention

[0005] In view of this, the present invention provides a fertilizer belt capable of precise fertilization and an infiltration irrigation system used in conjunction with the fertilizer belt, which can effectively fertilize under extremely water-saving conditions, saving fertilizer while satisfying the nutrients required for crop growth.

[0006] In order to achieve the above object, the present invention adopts the following technical solution: a fertilizer belt capable of precise fertilization, used in conjunction with an irrigation head, comprising:

[0007] The object carrier is a belt body with a cavity formed of a degradable material or a material with good water permeability;

[0008] The solid filler is granular and filled in the internal cavity of the storage carrier. The solid filler is soluble. The storage carrier and the solid filler cooperate to form a flexible material belt.

[0009] The technical effect of the present invention is that the storage carrier can pre-accommodate solid fillers. In specific implementation, the solid fillers are fertilizer particles, the storage carrier is a paper belt body or a water-permeable organic polymer material belt body, and the fertilizer belt composed of the storage carrier and the solid filler has a certain flexibility. When used in conjunction with an infiltration irrigation head, there is no need to worry about the problem of fertilizer particles falling off. The fertilizer belt is bundled with the water outlet membrane wire of the infiltration irrigation head for use. The water outlet position of the infiltration irrigation head corresponds to the fertilizer belt. Where the infiltration irrigation head outlets water, the fertilizer belt is moisturized and dissolved by the outlet water, and then absorbed and utilized by the roots of plants, which can better position fertilization. The fertilizer is effectively moisturized when the infiltration irrigation head outlets water, so that the fertilizer nutrients are effectively applied, and the crop roots effectively absorb the fertilizer nutrients, avoiding fertilizer waste caused by ineffective fertilizer application, and can also accurately apply fertilizer near the crop roots to ensure crop growth.

[0010] Preferably, the object carrier is a degradable paper tape or an organic polymer material tape with good water permeability.

[0011] The resulting technical effect is: the paper belt has good water permeability, can effectively infiltrate fertilizer, and does not affect the growth of crop roots in the later stage. The water-permeable organic polymer material belt actually has a number of tiny water-permeable holes, thus achieving a water-permeable effect.

[0012] Preferably, the solid filler is slow-release compound fertilizer granules or biological organic fertilizer granules.

[0013] The resulting technical effect is: slow-release compound fertilizer dissolves slowly, can exist for a long time, and provide fertilizer for a long time, completing fertilizer supply within the plant's growth cycle; biological organic fertilizer can provide the nutrients needed for plant growth, and the fertilizer source is wide.

[0014] The present invention also discloses an infiltration irrigation system, which uses the above-mentioned fertilizer belt and includes: a water supply pipeline, an infiltration irrigation head and a flexible material belt. The infiltration irrigation head has multiple groups and is arranged at intervals on the water supply pipeline. Each of the infiltration irrigation heads is radially provided with multiple membrane threads. The outer side of the membrane threads is connected to a flexible material belt. The membrane threads correspond to the flexible material belt one by one and form a fertilizer bundle. The flexible material belt is filled with hydrolyzable nutrient fertilizer. The fertilizer bundle is pre-wound around the root system of seedling crops.

[0015] The technical effect of the present invention is that the membrane wire and the material belt constitute a fertilizer bundle, and the fertilizer bundle can be pre-wound on the root system of the seedling crops. Compared with the traditional form of bonding fertilizer particles to the outside of the membrane wire, the fertilizer is not easy to fall off when the membrane wire is wrapped, thereby avoiding the loss of fertilizer due to ineffective application. Since the membrane wire and the fertilizer belt are arranged side by side, the present invention relies on the water seepage of the membrane wire to moisten the soil, and at the same time, the fertilizer in the fertilizer belt is infiltrated, thereby dissolving the fertilizer components for absorption by the crop roots, thereby realizing accurate and effective fertilizer application.

[0016] Preferably, the infiltration head includes a membrane thread seat and a pipe interface, the membrane thread seat is fixedly connected to the branch pipe outlet of the water supply pipeline, the membrane thread seat is a tubular structure, one end of a plurality of membrane threads are bundled and fixed inside the membrane thread seat, and the end of the membrane thread is connected to the pipeline, the other end of the membrane thread is sealed, and sealant is filled between the inner side of the membrane thread seat and the membrane thread bundle.

[0017] The resulting technical effect is that the membrane thread seat head needs to establish a passage relationship between the pipeline and the membrane thread while fixing the membrane thread, so as to achieve smooth water flow into the membrane thread and seep out.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] See the attached Figures 1 to 4 According to an embodiment of the present invention, a fertilizer belt capable of precise fertilization is used in conjunction with an irrigation head, and includes:

[0025] The object carrier 1 is a belt body formed of a degradable material and having a cavity, and is specifically a long thin belt when in use; it can also be a long thin belt made of a material with good water permeability;

[0026] The solid filler 2 is granular and filled in the internal cavity of the storage carrier 1 . The solid filler 2 is soluble. The storage carrier 1 and the solid filler 2 cooperate to form a flexible material belt 3 .

[0027] In the specific implementation, the object carrier 1 is a degradable paper strip. The solid filler 2 is a slow-release compound fertilizer granule or a biological organic fertilizer granule. It should be noted that the outer diameter of the formed flexible material strip is within the range of 5 mm to 20 mm.

[0028] Slow-release compound fertilizer granules or biological organic fertilizer granules slowly release the effective nutrients for crops over time through the chemical compounding or physical action of nutrients. Compound fertilizers include a variety of nutrients needed by crops (nitrogen fertilizer, phosphorus fertilizer, potassium fertilizer, biological fertilizer, etc.), with a wide variety of nutrients, high content, few by-products, low cost, good physical and chemical properties, and closely combined with scientific fertilization, which is conducive to transforming agricultural scientific and technological achievements into productivity and promoting the efficient development of agriculture, forestry and animal husbandry.

[0029] The present invention also discloses an infiltration irrigation system, which uses the above-mentioned fertilizer belt, and includes: a water supply pipeline 6, an infiltration irrigation head 7 and a flexible material belt 3. The infiltration irrigation head 7 has multiple groups and is arranged at intervals on the water supply pipeline 6. Each infiltration irrigation head 7 is radially provided with multiple membrane threads 71. The number of membrane threads is determined according to actual needs. The outer side of the membrane thread 71 is connected to the flexible material belt 3 in parallel. It should be noted that when it is used, the flexible material belt can be connected to the membrane thread in a spiral winding manner, and can also be bonded with a soluble adhesive, which can be reasonably selected according to actual conditions.

[0030] The membrane filaments 71 correspond to the flexible material strips 3 one by one and form a fertilizer bundle 5. The flexible material strips 3 are filled with hydrolyzable nutrient fertilizers. The fertilizer bundle 5 is pre-wound around the root system of the seedling crops.

[0031] Compared with the fertilization method of bonding fertilizer particles to the outer wall of the membrane wire, the present invention does not need to consider the loss caused by fertilizer falling off when burying the membrane wire. The infiltration water on the membrane wire can infiltrate the soil at the roots of the crops while also infiltrating the fertilizer in the fertilizer belt, thereby dissolving the fertilizer components for the crops to absorb. The part where the fertilizer belt of the present invention is wrapped coincides with the partial area where the membrane wire of the infiltration head outlets water, so that accurate water and fertilizer release can be achieved, and there is no waste of invalid fertilizer in the waterless soil area.

[0032] Specifically, the infiltration head 7 includes a membrane thread seat 72 and a pipe interface 73. The membrane thread seat 72 is fixedly connected to the branch pipe outlet of the water supply pipeline 6. The membrane thread seat 72 is a tubular structure. One end of a plurality of membrane threads is bundled and fixed inside the membrane thread seat 72, and the end of the membrane thread is connected to the pipeline. The other end of the membrane thread 71 is sealed to reduce water loss. It only relies on the micron-level pore characteristics of the membrane thread itself to infiltrate, and can also effectively prevent muddy water from flowing back and clogging the seepage holes. The inner side of the membrane thread seat 72 and the space between the membrane thread bundle are filled with sealant to ensure effective sealing of other parts except the membrane thread passage.

[0033] This product can apply fertilizers accurately and effectively, ensuring that fertilizer nutrients are fully absorbed by crops while saving water through infiltration irrigation. It only requires the fertilizer bundle to be pre-wound around the roots of seedling crops (such as seedlings), solving the problem of accurate fertilization in arid and water-scarce areas and achieving effective fertilizer application.

[0034] As for the device and the method of use disclosed in the embodiment, since they correspond to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the description of the method part.

[0035] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
