Problems solved by technology

[0003] At the same time, in the ecological restoration of exposed slopes, a large amount of peat soil, wood fiber and other materials will be used to provide organic matter in the foreign soil, and the peat soil with the largest amount needs to be purchased from the Northeast. Exhausted, the price also skyrocketed, more serious is that the resource will destroy the local ecological environment

Embodiment 1

[0025] The sludge plant growth substrate of the present invention includes main materials and auxiliary materials. The main materials include straw fibers and decomposed sludge compost. The decomposed sludge compost refers to the decomposed sludge obtained after sewage treatment in sewage treatment plants, wherein rich Containing a large amount of organic matter, nitrogen, and phosphorus, it can greatly increase the nutrient content of the substrate, and at the same time, the heavy metals, parasites, and germs contained therein should meet the restriction standards for garden application substrates; the straw fiber can be wheat, rice, corn, oil The remaining parts of crops (peanuts, sunflowers), cotton, sugar cane and other crops after harvesting are obtained by crushing and processing, which can increase the content of organic matter, and at the same time improve the interweaving and interconnection of each component, thereby improving the erosion resistance of the slope; The ...

Embodiment 2

[0032] The difference between this embodiment and the above-mentioned embodiment is that the air pressure or hydraulic spraying machine is used to transport the passenger soil, which specifically includes the following steps:

[0033] A. Mix the main material of the sludge plant growth substrate with the garden soil at a ratio of 1:1 to 3, and add the auxiliary materials of the sludge plant growth substrate while stirring. The ratio is the same as in Example 1 until the mixed Each component is stirred evenly to prevent the local content of a single component from being too high;

[0034] B. Use air pressure or hydraulic spraying machine to transport the mixed components to the slope to form guest soil layer;

[0035] C. After the guest soil layer is formed, plant seeds are added to each component, and the pneumatic or hydraulic sprayer is still used to sow the seeds to repair the slope.

Embodiment 3

[0037] The difference between this embodiment and the above-mentioned embodiment is that its application site is a low and gentle slope that requires greening, and it specifically includes the following steps:

[0038] A. Use a three-dimensional net to protect the slope on the low and gentle slope to strengthen the overall structure of the slope and prevent the loss of soil and nutrients;

[0039] B. Stir the sludge plant growth substrate and garden soil at a ratio of 1:1 to 3 evenly to prevent the local content of a single component from being too high to form a mixed guest soil;

[0040] C, the mixed guest soil that is stirred evenly is directly covered on the described three-dimensional net to form a guest soil layer;

[0041] D. Sow seeds, cover with non-woven fabric, pour water to form a stable guest soil layer, and complete slope repair.

Abstract

The invention relates to a sludge plant growth substrate and a side slope sludge soil replacement greening method. The sludge plant growth substrate comprises main materials and auxiliary materials, the main materials comprise straw fiber and mature sludge compositing, the auxiliary materials comprise one or a mixture of a chemical fiber, a water-retaining agent, an adhesive, bacterial manure, a soil conditioner, a microelement fertilizer or a disinfect insecticide; the part by weight ratio of the straw fiber to the mature sludge compositing to the auxiliary materials is (7-17):(80-90):(2-5). According to the sludge plant growth substrate and the side slope sludge soil replacement greening method provided by the invention, the turfy soil is replaced by qualified sludge compositing for the field of ecological restoration, the problems that the soil replacement is easy to lose and the organic matter is insufficient in the side slope repairing are solved; furthermore, the loss of the nutrient in the substrate is avoided, the effects of avoiding weakness and turning waste into wealth are achieved, and the potential risk is eliminated.

Description

technical field [0001] The invention relates to a side slope greening technology, in particular to a sludge plant growth substrate plant growth method and a side slope sludge guest soil greening method. Background technique [0002] Sludge treatment and disposal is the most important link in sewage treatment plants. It is the goal pursued by sewage treatment plants to reduce the amount of sludge, make it harmless, and even turn it into a resource. At present, the commonly used sludge disposal methods include: landfill, incineration, agriculture and landscaping. Landfilling will not only occupy a large amount of arable land, but also emit foul odor after accumulation and fermentation due to the large amount of organic matter and heavy metals contained in the sludge, which will generate flammable gases and even leak harmful substances, resulting in secondary pollution and potential safety hazards. Incineration is an effective measure for the complete harmlessness and reducti...
