Problems solved by technology

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] Embodiment 1 The preparation of the environmental protection light weight vegetation quilt block of the present invention

[0036] Step (1) classify and prepare the following types of raw materials:

[0037] Polymer water-absorbing materials: Recycled diapers, sanitary napkins, absorbent paper, etc. that have been sterilized by high temperature, and the sterilization temperature is not higher than 90 degrees Celsius.

[0038]Plant-based agricultural and forestry decomposable waste: crop straw, forest litter, fruit shell, bark, edible mushroom residue, traditional Chinese medicine factory residue and / or fermentation industry residue, 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 fine powder of 0.5-1mm for use.

[0039] Dried cattle and sheep manure: sterilized and dried at high temperature, crushed into 3-20mm pieces.

[0040] Waste plastics: waste plastic bags, plastic ...

Embodiment 2

[0063] Embodiment 2 Vegetative cover block of the present invention and the comparison of soil lawn

[0064] Materials: Grass species: bluegrass and tall fescue mixed at 50%:50%.

[0065] Table 1

[0066]

[0067] The results of the comparison are shown in Table 1: Vegetative cover blocks save 67% of water in the seedling period of the lawn, shorten the seedling cycle by 30%, and can emerge from the nursery in 45 days. 320 days; and the weight of the lawn with soil is 11.6 times that of the vegetation without soil. The lawn with soil needs to be sprayed with water once every 6 days in the high temperature period, while the vegetation with vegetation only needs to be sprayed with water once every 10 days. The water saving effect is obvious , The effect of green landscape is outstanding. The lightweight vegetation cover blocks can rot and return to the soil after a few years, improving the fertility of the land, while traditional non-woven lawns are difficult to remove. In...

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 environment-friendly lightweight vegetation quilt block for raising seedlings in agricultural and forestry containers. Background technique [0002] my country is a large arid country. Due to historical reasons, a large population and high resource-dependent economic growth, China has become the second largest emitter in the world. Over-exploitation and discharge have increased the ecological load and gradually reduced arable land. Water resources are increasingly scarce, and urban The water for green irrigation is gradually restricted, and the continuous accumulation of urban domestic waste has become a hot spot that people pay attention to. Especially in rural areas, except for a few straws returned to the field for feeding, most of the remaining straws are incinerated and discarded, which greatly wastes resources and pollutes the environment. While ...
