[0047] The embodiments of the present disclosure will be described in detail below with reference to the drawings.

[0048] The embodiments of the present disclosure will be described in detail below with reference to the drawings.

[0049] It is to be understood that the embodiments described herein are for illustrative purposes and that various modifications or changes in light thereof will be suggested to persons skilled in the art and are to be included within the spirit and purview of this disclosure and scope of the appended claims. It is also to be understood that any one or more of the teachings, genes, compositions, example, embodiments, examples, or examples described herein can be implemented in various forms of hardware, software, firmware, or a combination of these. In the

[0050] It is also to be understood that the drawings are in schematic form and that the various components shown in the drawings are not necessarily drawn to scale and that the actual implementation of the various components can vary in size, shape and dimensions from that shown in the drawings. It is also to be understood that the layout of the various components can be more complex than that shown in the drawings.

[0051] In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular architectures, interfaces, techniques, etc. in order to provide a thorough understanding of the examples. However, it will be apparent to those skilled in the art that the described aspects can be practiced in other

[0052] In one embodiment of the present disclosure, a biomass solid well chamber well cavity 1 is provided, as shown in the drawings, comprising: Figure 1

[0053] The well cavity 1 is in multiple groups and is arranged under the ground surface of the plant roots;

[0054] The drip irrigation well body 2 is buried in the well cavity 1 and is a solid porous structure composed of biomass particles;

[0055] The drip irrigation pipe 3 is laid under the ground surface, and each water outlet is connected to one drip irrigation well body 2;

[0056] Wherein: each of the biomass particles is connected based on ganoderma lucidum mycelium.

[0057] In this embodiment, the drip irrigation well is arranged on the cultivated land or forest land, and the density and distribution mode of the drip irrigation well are adaptively configured according to the planting density and the arrangement mode of the crops. The well cavity 1 is directly excavated, and the shape is determined according to the shape of the drip irrigation well body 2. Different from the existing drip irrigation technology, a plurality of well cavities 1 are directly excavated around the cultivated objects in this embodiment, and the drip irrigation well body 2 with a solid porous structure is filled in the well cavities 1

[0058] ​The drip irrigation well body 2 of the embodiment is different from the traditional drip irrigation well body 2 and drip irrigation port, adopts a solid porous structure, and has extremely high water absorption and air permeability. Since the well cavity 1 is buried underground, compared with the existing drip irrigation technology, the well cavity 1 of the embodiment is more water-saving and has stronger fertilizer and moisture retention.

[0059] The preparation raw material of the drip irrigation well body 2 of the embodiment is biomass chip particles, which can be obtained after agricultural and forestry waste is fermented by ganoderma lucidum. After fermentation, the particles are directly bonded based on the mycelium produced by ganoderma lucidum. After dehydration of the mycelium of ganoderma lucidum, the cell structure shrinks, the volume significantly decreases, the texture becomes brittle, and it is easy to break into powder or granular form, thereby increasing the porosity of the drip irrigation well body 2. At the same time, when the mycelium of ganoderma lucidum extends in the plant chips, it will secrete extracellular polysaccharides (such as β-glucan) and sticky proteins, which will wrap the biomass particles, forming a dense three-dimensional network structure, resulting in the adhesion of the whole drip irrigation well body 2 into blocks.

[0060] In the embodiment, agricultural and forestry waste is used as raw material, which is crushed and filled into a mold under pressure. After pressure, ganoderma lucidum is directly added to the mold. After fermentation, pores are generated in the biomass particle material. In the embodiment, the width of the visible pores of the drip irrigation well body 2 after fermentation is controlled based on the fermentation temperature, humidity and time, and is 0.1-1mm.

[0061] In the embodiment, in order to facilitate burial, the drip irrigation well body 2 is in a cylindrical structure, and the well cavity 1 is arranged in a shape following the drip irrigation well body 2. The diameter of the drip irrigation well body 2 is 15-25cm, and the length is 70-90cm. The drip irrigation well body 2 of this size has high adhesion strength, is easy to be wrapped by plant roots, and has higher moisture and fertilizer retention efficiency.

[0062] The embodiment effectively utilizes agricultural and forestry waste, reduces pollution of waste to the environment, realizes recycling of resources, and meets the concept of sustainable development. The drip irrigation well is made of all biomass materials and can be naturally degraded, which will not pollute the soil environment and is conducive to protecting the soil ecology.

[0063] The structure design of the drip irrigation well body 2 of the embodiment has good water absorption and porosity, can store a large amount of water and slowly release it, improves the utilization rate of water resources, and reduces the irrigation frequency. The water and fertilizer retention performance is good, which can reduce the loss of fertilizer, improve the utilization rate of fertilizer, and reduce the cost of fertilization. The characteristic of inducing root growth is helpful for the growth of crop roots into the drip irrigation well, and enhances the absorption and utilization of water and nutrients by crops.

[0064] In some embodiments, in order to realize automatic control, the drip irrigation well further comprises a humidity sensor 5 and a controller 4.

[0065] The humidity sensor 5 is arranged at the root of the plant; the control system is electrically connected with the humidity sensor 5, and the water pump 7 is electrically connected with the control end. The humidity sensor 5 of the embodiment collects the soil humidity at the root of the crop in the farmland or woodland, and preferably uses the existing resistance or conductance sensor; the data of the humidity sensor 5 is transmitted to the controller 4, the controller 4 is provided with a fixed threshold value or multiple ladder threshold values, and the pump water is controlled based on the ladder threshold value to change the flow in real time, or the water pump 7 is turned on when the soil humidity is lower than the fixed threshold value, and the water pump 7 is not operated at other times; and the drip irrigation of the crop area is automatically realized. The humidity sensor 5 of the embodiment is in multiple groups and is uniformly distributed on the crop planting ground.

[0066] In one embodiment, in order to realize automatic control based on a simple structure, the controller 4 comprises:

[0067] A single-chip microcomputer, of which the data input end is electrically connected with the humidity sensor 5;

[0068] A relay, of which the control end is electrically connected with the control end of the single-chip microcomputer.

[0069] The single-chip microcomputer of the embodiment is a simple electronic logic operating device, receives the amplified electrical signals of multiple humidity sensors 5, compares the average humidity with the set threshold value after mean value operation, generates a control signal when the average humidity is less than the threshold value, the control signal is used as the opening and closing control signal of the relay, and the opening and closing of the high-voltage end of the relay controls the power on-off of the water pump 7. The power end of the water pump 7 is connected with the execution end of the relay in the embodiment, and the pumping outlet is connected with the drip irrigation pipeline 3.

[0070] In some embodiments, the drip irrigation well further comprises a flow sensor 6 to realize precise control, and the flow sensor 6 is installed on the drip irrigation pipeline 3. The flow sensor 6 is used to monitor the flow of the drip irrigation well, so as to ensure the stability and uniformity of the drip irrigation.

[0071] In some embodiments, in order to take into account the economy and reduce the amount of incineration, the particulate matter comprises broken: pear pruning branches, apple pruning branches, cotton stalks, pepper stalks, corn stalks and / or wheat stalks. The particulate matter of the embodiment has large amount, is easy to obtain and has low cost, and the use of these particulate matters as raw materials can assist in the treatment of agricultural and forestry waste on a large scale.

[0074] S102: Place the drip irrigation well body 2 in the well cavity 1, and connect the drip irrigation well body 2 with the drip irrigation pipeline 3.

[0075] Taking fruit trees as an example, in this embodiment, holes (well cavities 1) with a diameter of 20 cm and a length of 80 cm are drilled on both sides of the fruit trees according to the growth conditions and water requirements of the fruit trees, and the number of holes can be 2, 4 or 6. The prepared drip irrigation well body 2 is installed into the drilled hole to ensure that the drip irrigation well body 2 is in close contact with the soil. The well cavity 1 is connected with the drip irrigation pipeline 3 system, and after the water source is connected, drip irrigation of the fruit trees can be realized. During the drip irrigation process, water and nutrients are slowly released into the surrounding soil through the porous structure of the well cavity 1 and are absorbed by the root system of the fruit trees. The system can be reinstalled according to the actual needs of the orchard every year to improve the soil organic matter of the orchard.

When the granular material is extruded, the granular material is poured from one end opening of the cylindrical mold, and the granular material in the mold is extruded based on a set pressure based on a stamping device (the specific type is not limited here, which has an extrusion head and sufficient pressure). The mold can also be provided with an extrusion zone and a forming zone with a certain length.
