Description

Technical Field

[0001] The invention relates to a landscape plant cultivation facility, and more particularly to a cultivation device for breeding and cultivating landscape plants using a silt matrix. Background Art

[0002] Silt is a fine-grained material formed by weathering products being transported to a still water environment by water, wind or glaciers. It is characterized by fine particles, strong water retention, high organic matter content, but poor air permeability. The formation process covers multiple stages such as erosion, transportation, deposition and compaction, and is jointly influenced by geology, climate and human activities.

[0003] However, the dredging of our country's densely networked waterways such as canals, rivers, lakes, etc. will produce a large amount of silt, and with the planning and upgrading of Shanghai's rivers, more river silt will be produced. How to effectively and recycle river silt according to local conditions is of great significance to avoid secondary pollution, recycle resources, and build a conservation-oriented society. Both at home and abroad, people are actively studying effective comprehensive utilization methods and technologies of silt. For the landscape plant industry, as people's living standards improve, people are paying more and more attention to their home environment. Bonsai art originated in China and has a long history and fine traditions. Its unique beauty is like a silent poem and a three-dimensional painting. It can not only decorate homes and environments, but also cultivate people's sentiments, please the body and mind, and give people a relaxed and happy feeling. Therefore, the market demand for landscape plants is growing, In the prior art, the water content of silt is relatively high. Due to soil erosion, the soil particles in the silt are smaller. The smaller particles will lead to smaller gaps, which will have a greater adhesion to water molecules, resulting in a lower oxygen content in the soil, which is not conducive to the development of vegetation roots. Therefore, developing a cultivation device with a simple structure that is suitable for using silt as a matrix to propagate and cultivate landscape plants is an effective way to solve this problem. Summary of the invention

[0004] One object of the present invention is to provide a cultivation device with a simple structure suitable for breeding and cultivating landscape plants using silt as a substrate.

[0005] According to one aspect of the present invention, there is provided a cultivation device for breeding and cultivating landscape plants using a silt matrix, wherein the cultivation device for breeding and cultivating landscape plants using a silt matrix comprises: an open treatment box, a dehydration and crushing assembly arranged in the treatment box, the dehydration and crushing assembly being used to treat the silt to a silt moisture content of ≤60%; The ratio control component includes two sets of electronic feeders, which store dewatered sludge and improver respectively, and the feed volume ratio is controlled at 1:7; The cultivation device comprises: a seedling box and a filter screen, wherein the filter screen is composed of a mesh with an aperture of 0.0015-0.003 mm, and a water-absorbing material that can be inserted into the filter screen is arranged in the seedling box; Optionally, a positioning column is arranged between the filter net and the seedling box, one end of the positioning column is in contact with the filter net, the positioning column is at least used to limit the relative position of the filter net to not change, and a reinforcement block is arranged between adjacent positioning columns, the reinforcement block is connected to adjacent positioning columns, and the reinforcement block is at least used to limit the positioning column to remain stable.

[0006] Optionally, a side of the reinforcement block close to the filter screen abuts against the filter screen, and the reinforcement block is a rectangular structure, and a narrow side of the reinforcement block abuts against the filter screen.

[0007] Optionally, a water storage tank is provided on one side of the reinforcing block abutting against the filter screen, and a water absorption hole is provided through the middle of the reinforcing block, and the water absorption hole is communicated with the water storage tank.

[0008] Optionally, water absorbing material is placed in the water absorbing hole.

[0009] Optionally, the filter mesh size of the filter is 0.002 mm.

[0010] Optionally, the sludge conditioner comprises, by volume percentage: 35-45% river sand, 25-35% coconut bran, 15-20% tree branch particles, 8-12% volcanic rock filter material, and 1-3% traditional Chinese medicine residues, wherein the tree branch particles are crushed particles of at least one of camphor, eucalyptus, and melaleuca, with a particle size of 2-5 mm.

[0011] In the present invention, the components of the sludge modifier are river sand, coconut husk, branch particles, and volcanic rock filter material, respectively. The branch particles are selected from finished products that have been prepared in daily work: the branch particles can be purchased, or the discarded branches collected during the daily urban greening management and maintenance process are crushed into particles by a crusher and then dried. Generally, the discarded branches collected during the daily urban greening management and maintenance process include aromatic tree species, and the aromatic tree species can be specifically selected from one or more of camphor trees, eucalyptus, melaleuca and burmanni. The branch particles can increase the porosity of the sludge, adjust its looseness, and provide nutrients at the same time. In addition, the branch particles can realize waste utilization, which is beneficial to saving resources and protecting the environment.

[0012] Coconut bran is a fiber powder of coconut shell, which is a byproduct or waste after coconut processing. Coconut bran has good water retention, which can reduce the loss of water and nutrients in the silt planting soil, thus facilitating the plant roots to absorb nutrients and water well during the growth process, which is beneficial to the growth of plants. In addition, the combination of coconut bran and branch particles can make the silt planting soil have good air permeability, prevent the planting soil from becoming pulpy, and prevent the plant roots from being corroded by the planting soil, which is beneficial to the growth of plants.

[0013] Aerobic microorganisms in the sludge can attach to the volcanic rock filter material, increasing the activity and number of aerobic microorganisms, thereby reducing the activity, number and reproduction rate of anaerobic microorganisms, thereby effectively reducing the odor produced during the metabolism of anaerobic microorganisms and reducing the odor of sludge planting soil. In addition, the combination of branch particles, coconut bran and volcanic rock filter material can improve the porosity of sludge, making the sludge planting soil looser, thereby promoting plant growth; it can reduce the total amount of organic pollutants in sludge and reduce the total number of bacteria in sludge. The higher the volume ratio of sludge particles to sludge conditioner, the more suitable it is for planting plants.

[0014] One technical effect of the present invention is that 1. Different from the existing sludge culture medium, the average particle size of the soil in the sludge is changed, so that large and small particles can be evenly distributed in the sludge culture medium, the adhesion of sludge particles to water molecules is improved, and the air concentration in the sludge culture medium is increased; 2. Because the water molecules in the sludge culture medium have strong adhesion, the water in the sludge culture medium is adsorbed in time through the water filter component to prevent the sludge culture medium and water molecules from forming a closed channel, preventing air from entering and causing the plant roots to rot.

[0026] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0027] Example The present invention provides a cultivation device for breeding and cultivating landscape plants using silt substrate, such as Figure 1-3 As shown, The invention comprises a treatment device 1, which comprises a treatment box 11. The upper surface of the treatment box 11 is open. An inclined introduction channel 12 is arranged on one side of the treatment box 11. The lower end of the introduction channel 12 is fixedly connected to the treatment box 11, and the higher end of the introduction channel 12 tends to be away from the treatment box 11. A dehydration and crushing assembly 13 is arranged in the treatment box 11. The dehydration and crushing assembly 13 can process sludge. A feeding port 14 is opened on one side of the treatment box 11. A baffle 15 is arranged for the feeding port 14. The baffle 15 is used to close the feeding port 14. One end of the baffle 15 is rotatably connected to the treatment box 11. An agitator 2 is arranged on one side of the treatment box 11.

[0028] When in use, the silt under the river and lake can be transferred to the shore by dredging equipment, and then soil testing can be carried out. The silt targeted by the present invention is naturally generated silt without major pollution, NY / T 1121.2-2006 Soil Testing Part 2: Determination of Soil pH; NY / T 1121.6-2006 Soil Testing Part 6: Determination of Soil Organic Matter; NY / T 53-1987 Soil Total Nitrogen Determination Method (Semi-micro Kelvin Method); NY / T 88-1988 Soil Total Phosphorus Determination Method; NY / T 890-2004 Determination of Available Zinc, Manganese, Iron and Copper Content in Soil - Diethylenetriaminepentaacetic Acid (DTPA) Extraction Method; GB / T17141-1997 Soil Quality Determination of Lead and Cadmium by Graphite Furnace Atomic Absorption Spectrophotometry; GB / T 14643.2-1993 Determination of soil flora in industrial circulating cooling water by plate counting method, ensure that there is no heavy metal pollution in the sludge, and then use the inlet channel 12 to introduce the sludge into the treatment box 11, and treat the sludge through the dehydration and crushing component 13 in the treatment box 11, and the dehydrated sludge obtained has a moisture content of less than or equal to 60% of dry sludge.

[0029] like Figure 1-3 As shown, a ratio control component 21 is arranged above the agitator 2, and the ratio control component 21 includes a locking frame 22. The locking frame 22 is vertically arranged, and two electronic feeders 23 are fixedly connected to the locking frame 22. Dehydrated and crushed sludge is stored in any one of the electronic feeders 23, and sludge improver is stored in the other feeder. The components of the sludge improver include river sand, coconut bran, branch particles, and volcanic rock filter material. The ratio of river sand: coconut bran: branch particles: volcanic rock filter material: traditional Chinese medicine residue is 2:3:1.8; the ratio of dehydrated and crushed sludge to sludge improver is 1:7; the dehydrated and crushed sludge and sludge improver are proportionally fed through the electronic feeder 23.

[0030] When in use, the components of the sludge conditioner are river sand, coconut bran, branch particles, and volcanic rock filter materials. The branch particles are selected from the finished products that have been prepared in daily work: the branch particles can be purchased, or the discarded branches collected in the daily urban greening management process can be crushed into particles with a crusher and then dried. Generally, the discarded branches collected in the daily urban greening management process include aromatic tree species, and the aromatic tree species can be specifically selected from one or more of camphor trees, eucalyptus, melaleuca and burmanni. The branch particles can increase the porosity of the silt, adjust its looseness, and provide nutrients. In addition, the branch particles can realize waste utilization, which is beneficial to saving resources and protecting the environment.

[0031] Coconut bran is a fiber powder of coconut shell, which is a byproduct or waste after coconut processing. Coconut bran has good water retention, which can reduce the loss of water and nutrients in the silt planting soil, thus facilitating the plant roots to absorb nutrients and water well during the growth process, which is beneficial to the growth of plants. In addition, the combination of coconut bran and branch particles can make the silt planting soil have good air permeability, prevent the planting soil from becoming pulpy, and prevent the plant roots from being corroded by the planting soil, which is beneficial to the growth of plants.

[0032] Aerobic microorganisms in the sludge can attach to the volcanic rock filter material, increasing the activity and number of aerobic microorganisms, thereby reducing the activity, number and reproduction rate of anaerobic microorganisms, thereby effectively reducing the odor produced during the metabolism of anaerobic microorganisms and reducing the odor of sludge planting soil. In addition, the combination of branch particles, coconut bran and volcanic rock filter material can improve the porosity of sludge, make the sludge planting soil looser, and thus promote plant growth; it can reduce the total amount of organic pollutants in sludge and reduce the total number of bacteria in sludge. The higher the volume ratio of silt particles to silt conditioner, the more suitable it is for planting plants. However, the higher the volume ratio of silt particles to silt conditioner, the lower the utilization rate of silt. If the utilization rate of silt is too low, the recycling of silt cannot be achieved. Therefore, in actual projects, based on considerations of silt utilization and economic benefits, the volume ratio of silt particles to silt conditioner is generally controlled within 1: (3.5-4). Within this ratio range, silt planting soil can be used to plant landscape plants and the utilization rate of silt is high. At this time, while using as much silt as possible, the normal growth of landscape plants can be guaranteed, which is economical and affordable.

[0033] The cultivation device 3 includes a base frame 31, a pedestal 32 and a seedling box 33. The base frame 31 is arranged on both sides of the left and right sides of the pedestal 32. The seedling box 33 is clamped on the pedestal 32. The seedling box 33 is used to cultivate landscape seedlings. The lower surface of the seedling box 33 is provided with an array of drainage holes (not marked), and the axis of the drainage holes is perpendicular to the lower surface of the seedling box 33.

[0034] like Figure 1-3As shown, a filter 34 is provided in the seedling box 33, and the size of the filter of the filter 34 ranges from 0.0015mm to 0.003mm, and is preferably 0.002mm in the present invention. A positioning column 35 is arranged in an array between the filter 34 and the seedling box 33, one end of the positioning column 35 is fixedly connected to the filter 34, and the end of the positioning column 35 away from the filter 34 is fixedly connected to the seedling box 33, and a reinforcing block 36 is provided between adjacent positioning columns 35, and the reinforcing block 36 is connected to adjacent positioning columns 35. The side of the reinforcing block 36 close to the filter 34 abuts against the filter 34, and the reinforcing block 36 is a rectangular structure, and the narrow side of the reinforcing block 36 abuts against the filter 34. A water storage tank 37 is provided on the side where the reinforcing block 36 abuts against the filter 34, and a water absorption hole 38 is opened in the middle of the narrow side of the reinforcing block 36, and the water absorption hole 38 is connected to the water storage tank 37, and a water absorption material 39 is placed in the water absorption hole 38.

[0035] As a preferred embodiment, the filter screen 34 can be arranged on the lower surface of the seedling box 33. Due to the effect of gravity, the water moves downward and flows out through the filter screen 34, thereby leaving relatively dry sludge. The filter screen 34 can be 5, which are respectively arranged on the front, back, left, right and lower surfaces of the seedling box 33 to increase the contact area between the filter screen 34 and the sludge, thereby accelerating the separation process of water and sludge. As a preferred embodiment, the water-absorbing material 39 in the water-absorbing hole 38 can be set at the upper end corresponding to the filter hole of the filter net 34 and penetrate into the sludge. Through the high water absorption of the water-absorbing material 39 and because it is placed vertically, the lower end of the water-absorbing material 39 condenses water droplets for drainage. The insertion length is adjusted according to the absorption of the water content of the sludge to achieve the control of the water content of the sludge.

[0036] When in use, since the particle diameter of the silt is between 0.002 mm (clay) and 0.063 mm (sand), it belongs to silt-grade particles with a fine texture, so the filter screen should be smaller than this size to prevent the loss of silt in the silt and achieve the water seepage effect at the same time. Since the size of the filter screen 34 is too small, it is easy to deform, and the weight of the silt is heavy because the water fills the gaps, the overall weight is heavy. Therefore, a reinforcing block 36 is added between the positioning columns 35 to increase the bearing capacity of the filter screen 34, and the narrow side of the reinforcing block 36 is abutted against the filter screen 34, reducing the number of filter screens 34 blocked by the reinforcing block 36; while increasing the support of the filter screen 34, the water filtration of the filter screen 34 is guaranteed; through the water storage tank 37 and the water absorption hole 38 set in the reinforcing block 36, the water passing through the filter hole of the filter screen 34 in the reinforcing block 36 can enter the water storage tank 37, and the water in the silt is drawn out through the water absorption material in the water absorption hole 38, and discharged through the drainage hole on the seedling box 33.

[0037] The main effects achieved by the present invention are: 1. Efficient treatment and utilization of sludge: The dehydration and crushing assembly 13 in the processing device 1 can effectively process the sludge, reduce its water content, and make it more suitable as a substrate for plant cultivation.

[0038] The introduction of sludge conditioner, by precisely controlling the volume ratio of dehydrated and crushed sludge to sludge conditioner, not only improves the utilization rate of sludge, but also improves the physical and chemical properties of sludge, such as air permeability, water retention and porosity, making it more suitable for plant growth.

[0039] 2. Optimize plant growth environment: The ingredients in the sludge conditioner (river sand, coconut bran, tree branch particles, volcanic rock filter material, etc.) work together to adjust the pH value, organic matter content, nutrient supply, etc. of the sludge, providing a suitable growth environment for plants.

[0040] The addition of coconut bran and branch particles enhances the air permeability and water retention of the silt, prevents the planting soil from becoming slurry, and protects the plant roots from corrosion.

[0041] Volcanic rock filter media helps to increase the activity and quantity of aerobic microorganisms, reduce the odor produced by anaerobic microorganisms, and improve the microecological environment of sludge planting soil.

[0042] 4. Promote healthy growth of plants: The provision of the filter 34 accelerates the separation process of water and sludge, helps to maintain a suitable humidity of the sludge, and prevents excessive water from causing root rot of plants.

[0043] The use of the water-absorbing material 39 in the water-absorbing hole 38 realizes the precise control of the water content of the sludge, further satisfying the water demand of the plant growth.

[0044] 5. Environmental protection and sustainable development: The device makes full use of sludge as a waste resource and converts it into a valuable plant cultivation matrix through scientific processing, thus realizing the recycling of resources.

[0045] The introduction of tree branch particles and other ingredients in the sludge conditioner not only improves the properties of the sludge, but also realizes the effective utilization of urban greening waste, which helps promote the green and sustainable development of the city.
