[0002] At present, the roofs of public buildings or areas with poor soil that need to be planted with lawns are usually covered with artificial turf or re-greening. However, laying artificial turf is costly and ineffective, and it cannot achieve true greening. If the plants are replanted, on the one hand, it takes a certain amount of time for the plants to grow, which is time-consuming and not timely. On the other hand, because the soil is directly exposed to the sun and rain, the soil's ability to absorb and lock water is usually poor, and the water holding capacity is low. When in use, it requires long-term and uninterrupted artificial water replenishment, which greatly limits its promotion and application.

[0053] In the following, the artificial solid soil, artificial grassland, preparation method and application of the present invention will be described in detail with reference to the accompanying drawings and exemplary embodiments.

[0054] Exemplary Embodiment 1

[0055] This exemplary embodiment provides a method for preparing an artificial grassland.

[0056] The method may include the following steps:

[0057] S1. Mix minerals, organic matter, microbial flora and water evenly to obtain a mixture;

[0058] S2. Process the mixture into a formed body to obtain a green body;

[0059] S3. Sow seeds on the green body, cure it, and maintain moisture. After the plants grow, an artificial grassland is obtained.

[0060] In this embodiment, the moisture maintenance may include watering regularly or irregularly.

[0061] In this embodiment, at least one surface of the processed green body has a number of non-penetrating holes, such as the upward-facing surface. The seeds can be sown all or partially in the holes.

[0062] In this embodiment, there are no holes on the surface of the processed green body, and seeds of plants are sown on the upward-facing surface of the green body.

[0063] In this embodiment, the step of mixing the mineral raw materials, organic matter, microbial flora and water evenly may include: evenly mixing X parts by mass of minerals, Y parts by mass of organic matter and Z parts by mass of microbial flora, and then adding 2X - 4X parts by mass of water and mixing evenly again.

[0064] Wherein, calculated according to X + Y + Z = 100 parts by mass, X = 30 - 50 parts, such as 31, 32, 35, 40, 45, 48, 49 parts, etc., Z is less than 1 part, such as 0.8, 0.5, 0.3, 0.2 parts, etc., and the balance is organic matter.

[0065] If the dosage of minerals is less than 30 parts, the strength of the produced product is insufficient and the forming effect is poor. For example Figure 3A and Figure 3BAs shown, the product is fragile; if it is higher than 50 parts, it will lead to a relatively reduced amount of organic matter used, and the resulting product cannot provide sufficient nutrients for plants. Compared with minerals and organic matter, the amount of added bacteria is less. On the one hand, it is due to economic reasons (that is, if too much bacteria is added, the cost is high), and on the other hand, after adding a small amount of bacteria, the bacteria can reproduce themselves.

[0066] In this embodiment, the steps of the shaping process may include: filling the mixture into a mold and extruding it to obtain a formed blank.

[0067] In this embodiment, the mineral will solidify when it encounters water, and the blank can be solidified, that is, the blank is placed in a cool place to dry or placed outdoors for natural solidification. Of course, the solidification can also be accelerated by heating. The solidification method of the present invention is not limited to this, and other solidification methods can also be used.

[0068] In this embodiment, the organic matter can be obtained by the synergistic fermentation and decomposition of kitchen waste, agricultural and forestry waste, and facultative anaerobic bacteria. The organic matter has high energy, diversity, and long-term effects, which requires that the source of the organic matter is a mixed base composed of plant-based and animal-based. Household kitchen waste and agricultural and forestry waste are natural choices.

[0069] Among them, the kitchen waste includes food-grade raw materials collected and alcoholized at home, that is, the organic matter comes from the food left over from our families; using kitchen waste as raw materials can not only solve the problem of difficult disposal of kitchen waste, reduce the amount of organic matter entering landfills, reduce the generation of odors and landfill leachate, but also utilize the organic components in kitchen waste and save costs.

[0070] The agricultural and forestry waste may include one or more of dead branches, straws, leaves, barks, sawdust, and animal feces. Agricultural and forestry wastes such as straws, dead branches, leaves, and barks have a low energy density and are extremely prone to decay after being affected by moisture. The difficulty of large-scale collection, transportation, and storage is very high. The present invention uses agricultural and forestry waste as raw materials to effectively solve the problem of its difficult treatment. Further, the agricultural and forestry biomass may include straws, branches and leaves, etc. The particle size of the agricultural and forestry organic matter is within 3 cm, and the water content is 25-35%, for example, the water content can be 30%.

[0071] As an option of the present invention, the agricultural and forestry biomass and the slurry-like organic matter containing facultative anaerobic fermentation bacteria can be laid in the fermentation tank in sequence; the facultative anaerobic fermentation bacteria are used for fermentation treatment to obtain organic matter. Among them, the temperature in the fermentation tank is controlled at 30-60 °C, such as 31 °C, 35 °C, 40 °C, 50 °C, 55 °C, 59 °C.

[0072] As another option of the present invention, holes or trenches can be dug in the land, and then the agroforestry biomass and the paste-like organic matter containing facultative anaerobic fermentation flora are filled in the holes or trenches, and then covered with soil, and the organic matter is obtained after fermentation.

[0073] Optionally, the mass ratio of the facultative anaerobic fermentation flora to the paste-like organic matter can be: 0.05-0.2%:1, such as 0.001:1, 0.0015:1.

[0074] Optionally, the mass ratio of the paste-like organic matter to the agroforestry biomass can be 1:3-1:5, such as 1:4.

[0075] Optionally, the paste-like organic matter includes the organic matter obtained by pulverizing and pulping kitchen waste; the size of the solid particles in the paste-like organic matter is not more than 3 cm, such as 0.3 cm, 1 cm, 1.5 cm, 2 cm, 2.5 cm, 2.9 cm, etc.

[0076] Optionally, in the paste-like organic matter:

[0077] The mass fraction of the organic matter is 15-25% (wet basis), such as 16%, 18%, 19.1%, 22%, 24.5%, etc.

[0078] The mass fraction of the total nutrients (N+P2O5+K2O) is 1-2% (wet basis), such as 1.1%, 1.4%, 1.6%, 1.9%, etc. The mass fraction of the total nitrogen (N) is 0.4-0.8% (wet basis), such as 0.5%, 0.6%, 0.7%, etc. The mass fraction of the organic phosphorus (P2O5) is 0.3-0.7% (wet basis), such as 0.4%, 0.5%, 0.6%, etc. The mass fraction of the potassium oxide (K2O) is 0.1-0.5% (wet basis), such as 0.2%, 0.3%, 0.4%, etc.

[0079] The pH is 5-6.5, such as 5.1, 5.5, 5.9, 6.4, etc.

[0080] The content of sodium (Na) is ≤0.2% (wet basis), such as 0.11%, 0.15%, 0.17%, 0.19%, etc.

[0081] The mass fraction of the biogenic fulvic acid is 0.8-1.2% (wet basis), such as 0.81%, 0.9%, 0.95%, 1.1%, etc.

[0082] The mass fraction of the total carbon is 6-10% (wet basis), such as 6.5%, 7%, 8%, 9.5%, etc.

[0083] In this embodiment, the mineral raw material may only include cement, and the proportion of cement in various raw materials such as mineral raw materials, organic matter, and bacteria is 30-50 wt%.

[0084] Alternatively, in addition to cement, the mineral raw material may further include inorganic compounds such as phosphorus (phosphorus pentoxide), potassium (potassium oxide), magnesium oxide, calcium oxide, aluminum oxide, silicon dioxide, and iron oxide.

[0085] Cement contains various nutrient elements required for plant growth. Cement is an inorganic glue with a solidifying property, which can bind various raw materials of artificial solid soil together in an organic and disordered manner after production and shaping. If the amount of cement is too large, it is close to or becomes an ore (for example, if the amount directly reaches 100%, it is an ore), and the nutrients required for plant growth such as organic matter, nitrogen, phosphorus, and potassium are almost zero, which is not conducive to plant growth. If the amount is too small, the mixtures of minerals, organic matter, etc. cannot be bound together in an organic and disordered manner, and the nutrient components such as minerals and organic matter are more likely to be lost with runoff when it rains or is watered.

[0086] In this embodiment, the mineral raw material may include inorganic compounds such as phosphorus (phosphorus pentoxide), potassium (potassium oxide), magnesium oxide, calcium oxide, aluminum oxide, silicon dioxide, and iron oxide.

[0087] In this embodiment, the addition amount of minerals should ensure that in the product: magnesium element ≤ 2%, sulfur element ≤ 1%, calcium element ≤ 45%, silicon element ≤ 8%, iron element ≤ 0.3%, aluminum element ≤ 1.2%, and "%" represents mass percentage. The control of the above mineral elements magnesium, silicon, and calcium elements is also very important for the shaping of the product. If it is not within the specified range, the product will be in a loose state or a fragile state and cannot be stably shaped.

[0088] In this embodiment, the addition amount of organic matter should ensure that in the product: organic matter ≥ 10%, total nutrients (N + P2O5 + K2O) ≥ 2%, sodium ion ≤ 0.2%, and pH value is 6-8.5.

[0089] In this embodiment, the bacteria group may include yeast, bacillus, acetic acid bacteria, mold, pancreatic enzyme, EM beneficial active bacteria, etc. It should be noted that the bacteria group of the present invention can be added according to actual needs. For example, for products used in alpine regions, cold-resistant yeast, etc. can be added.

[0090] The addition amount of the bacteria group should ensure that the number of bacteria group in the product (cfu) ≥ 200 million / kg.

[0091] In this embodiment, the dimensions of the green body or the cured green body may include: length 200 - 500 mm, width 100 - 500 mm, and thickness 40 - 100 mm. For example: 250 mm × 250 mm × 60 mm, 250 mm × 240 mm × 80 mm, 480 mm × 480 mm × 90 mm, 250 mm × 125 mm × 50 mm, 240 mm × 115 mm × 50 mm, 240 mm × 120 mm × 60 mm, etc. Controlling the dimensions within the above range is beneficial for the stability of the structure, high consistency in quality, high efficiency in production and manufacturing, convenience in transportation and paving, and convenience in subsequent maintenance.

[0092] In this embodiment, the density of the artificial solid soil is 0.29 g - 0.32 g / cm 3 , for example, 0.30, 0.31 g / cm 3 .

[0093] In this embodiment, the maximum water absorption of the artificial solid soil can be 1 - 1.2 times its own mass, for example, 1.05, 1.1, 1.15 times, etc.

[0094] Exemplary Embodiment 2

[0095] This exemplary embodiment provides a method for preparing an artificial grassland.

[0096] The difference between the method in this exemplary embodiment and that in Exemplary Embodiment 1 is that the seeds are mixed before processing and forming, and there is no need to sow seeds on the green body; other steps can be the same as those in Exemplary Embodiment 1. For example, the minerals, organic matter, flora, and water can be the same as those in Exemplary Embodiment 1, and the methods of forming, curing, and moisturizing and maintaining can all be the same as those in Exemplary Embodiment 1.

[0097] Specifically, the method may include the following steps:

[0098] Mix the minerals, organic matter, flora, and water evenly to obtain a first mixture;

[0099] Mix the first mixture with the seeds to be planted to obtain a second mixture;

[0100] Perform forming processing on the second mixture to obtain a green body;

[0101] Cure, moisturize and maintain, and an artificial grassland is obtained after the plants grow out.

[0102] In this embodiment, at least one side of the processed body may have a plurality of non-through holes, or the surface of the processed body may have no holes. Further, the upper surface of the processed body may have a plurality of non-through holes. By providing non-through holes, the present invention can increase the surface area and lock water more effectively when watering or raining, which can help the seeds grow out of the body and continue to grow.

[0143] One of the innovations of the present invention lies in that the formation process of natural soil is the aggregate particles formed by the interaction of organic matter, minerals, biological flora and water. The present invention simulates the formation process of natural soil, and artificially arranges and combines minerals, organic matter, flora and water (or cement, other minerals, organic matter, flora and water) to calculate the form and content of artificial solid soil, solving some disadvantages of natural soil in some special application scenarios, such as poor water retention, poor fertilizer retention and fast loss on the greening of building roofs. It realizes the qualitative, quantitative and shaped provision of different artificial black soils according to different scenarios, provides a growth base for lean greening, and has functions such as preventing surface runoff, water absorption, water retention and fertilizer retention.

[0144] The second innovation lies in simplifying the traditional turf greening process into a workshop standardized production process. In the traditional greening process, artificial soil preparation, seeding, management, turf taking, and then loading and transporting to the construction site are required for turf production; the construction site to be greened needs to lay a soil base layer; finally, the turf is laid; and maintenance is carried out. However, the artificial grassland of the present invention is a workshop standardized production process. In the factory, minerals, organic matter, flora and water are mixed and grass seeds are added. After forming, it is maintained in the workshop. When the grass germinates and grows into a block of turf, the artificial solid soil and the grass grow and merge into one, which is the artificial grassland; the artificial grassland is transported to the construction site to be greened and directly paved, and watered regularly. There is no need to lay soil on the surface greening of buildings, and there will be no runoff causing soil loss.

[0145] Although the present invention has been described above in conjunction with exemplary embodiments and the accompanying drawings, those of ordinary skill in the art should clearly understand that various modifications can be made to the above embodiments without departing from the spirit and scope of the claims.
