A large number of unrestrained mining has seriously damaged the surface plants, making the ecosystem more fragile, reducing the function of water conservation, salinization of large areas of fertile land, and serious damage to land resources. Nowadays, is there any soilless lawn on the market? Textile fabrics are not perishable, and the field of use is single. Plastic containers are labor-intensive and time-consuming, and the cost is high. Many shortcomings are extremely inconsistent with the low-carbon life of modern people. In the country's construction of modern garden cities, the process of industrialized soilless cultivation of agriculture and forestry Among them, the reuse of organic solid waste and agricultural and forestry waste can alleviate the output of waste and the excessive exploitation of original resources; overcome the current situation of insufficient water and nutrients in greening and planting substrates, improve the benefits of agricultural and forestry planting, fix carbon dioxide, and alleviate The urban heat island effect increases biodiversity, saves precious fresh water resources, and finds all feasible, economical and reasonable resource recycling methods for urban solid organic waste and agricultural and forestry waste
[0005] Although municipal solid waste is a raw material for plant cultivation substrates with a wide range of sources, since many substrates contain human and animal feces during municipal solid waste disposal, harmful waste gas and waste water will be produced during the production of vegetation blocks. Vegetation cover blocks (lawn) will have odor, which will affect its market acceptance. There are no reports of making vegetation cover blocks, and the traditional treatment is just to be buried in the soil and decompose naturally
Extremely low recycling rate

Embodiment 1
[0035] Example 1 Preparation of environment-friendly lightweight plant quilt of the present invention
[0036] Step (1) Classify and prepare the following types of raw materials:
[0037] Polymer absorbent material: high temperature sterilized recycled diapers, sanitary napkins, absorbent paper, etc., the sterilization temperature is not higher than 90 degrees Celsius.
[0038] Decomposable wastes of plant agriculture and forestry: crop straws, litter of forest trees, fruit shells, bark, edible mushroom residues, medicine residues from traditional Chinese medicine factories and / or residues from fermentation industry, after high temperature sterilization and drying, most of them are crushed Fragments of 3-20mm are ready for use, and a small part is crushed into fines of 0.5-1mm for later use.
[0039] Dry cow and sheep dung: After high temperature sterilization and drying, it is crushed into 3-20mm fragments.
[0067] The comparison results show as Table 1: The vegetation quilt saves 67% of the water during the nursery period, shortens the nursery cycle by 30%, and can be out of the nursery within 45 days. The green period of Beijing soil lawn is 280 days, while the soilless vegetation quilt is 320 days; and the weight of the soil turf is 11.6 times that of the soil-free vegetation quilt. The soil turf needs to be sprayed every 6 days in the high temperature period, while the vegetation quilt only needs to be sprayed once every 10 days, which has obvious water saving effects , The green landscape effect is outstanding. Lightweight vegetation quilts can rot and return to the soil in a few years, improving the soil's fertility, while traditional non-woven lawns are difficult to remove...

Abstract
The invention relates to an environment-friendly lightweight vegetation block, belonging to environment-friendliness and resource recycling. The vegetation block is made by adding mesh-shaped organic plants, waste slurry of a paper-making factory and a growth retardant PP333 to agricultural wastes, urban organic solid garbage and Chinese medicine slag, coal ash and furfural mushroom residues of a factory and water retaining materials recovered from the garbage; and the vegetation block is mainly used for container factory lightweight seedling culture of a forestry flower industry, desertification governance, sand vegetation recovery, landslide vegetation recovery, urban roof greening, cell high-salt field greening and planting of a football field and a golf course. According to the invention, not only raw material resources is protected, the function of ecosystem balance is increased, and the efficiency of plantation is improved, but also an effective resource recycling path for urban household garbage, agriculture and forestry wastes and factory organic garbage is found out so that renewable resources are subjected to highly economic optimization combination and are more utilized effectively and reasonably.
Description
Technical field [0001] The invention relates to the field of environmental protection and resource reuse, in particular to an environmentally friendly lightweight plant quilt for nursery and forest container seedlings. Background technique [0002] my country is a big arid country. Due to historical reasons, a large population and high resource-dependent economic growth, China has become the world's second largest emitter. Excessive exploitation and emissions have increased the ecological load and gradually reduced arable land. Among them, water resources are increasingly scarce. Greening irrigation water is gradually restricted, and the continuous accumulation of urban domestic waste has become a hot spot of people's attention. In particular, the remaining crop straws in rural areas, except for a few straws that are returned to the field, are mostly burned and discarded, which greatly wastes resources and pollutes the environment. While the output of garbage is increasing rapidly...
