Problems solved by technology

The silt used in the above-mentioned patent contains a large number of bacteria, and the original silt is mostly acidic, and it is easy to cause secondary pollution when neutralized with general chemicals. At the same time, the original silt is viscous and lacks gaps, so it is not suitable for direct use for composting fermentation. The above-mentioned patent is in When composting, additional cold water needs to be added to control the water content, and there is no detailed description of the area required for composting

Embodiment 1

[0024] Embodiment one: the method for making family potted plant nutrient soil, its operating steps are:

[0025] 1) Put the silt with a water content of 80% under the greenhouse and spread it flat. The thickness of the silt is 50 cm. If the thickness is too thick, it will not be easy to compost and ferment. The surface of the above mixture is naturally dried for a week after drainage ditch is opened; polyacrylamide is used to quickly dehydrate the sludge to reduce the water content of the sludge.

[0026] 2) Sprinkle crushed clam shells and slag on the above sludge, the diameter of clam shells and slag is 8mm, and the volume ratio of sludge, clam shells, and slag is 1:0.15:0.3, and then carry out the first stirring, Aeration; using clam shells, slag and other organic and inorganic waste media to change the physical properties of the silt, changing the physical properties of the soil aggregate structure of the original silt from extremely sticky to relatively loose.

Embodiment 2

[0033] Embodiment two: make the method for household potted plant nutrient soil, its operating steps are:

[0034] 1) Put the silt with a water content of 70% under the greenhouse and spread it flat. The thickness of the silt is 40 cm. If the thickness is too thick, it will not be easy to compost and ferment. The surface of the above mixture is naturally dried for a week after drainage ditch is opened; polyacrylamide is used to quickly dehydrate the sludge to reduce the water content of the sludge.

[0035] 2) Sprinkle crushed clam shells, slag on the above sludge, the diameter of clam shells and slag is 6mm, and the volume ratio of sludge, clam shells, and slag is 1:0.1:0.3, and then carry out the first stirring, Aeration; using clam shells, slag and other organic and inorganic waste media to change the physical properties of the silt, changing the physical properties of the soil aggregate structure of the original silt from extremely sticky to relatively loose.

Embodiment 3

[0042] Embodiment three: the method for making family potted plant nutrient soil, its operating steps are:

[0043] 1) Put the silt with a water content of 60% under the greenhouse and spread it flat. The thickness of the silt is 30 cm. If the thickness is too thick, it will not be easy to compost and ferment. Then sprinkle 1.5 kg of polyacrylamide on every 100 kg of silt. The surface of the above mixture is drained and dried naturally for a week; the sludge is dehydrated quickly by using polyacrylamide to reduce the water content of the sludge.

[0044] 2) Sprinkle crushed clam shells, slag on the above sludge, the diameter of clam shells and slag is 6mm, and the volume ratio of sludge, clam shells, and slag is 1:0.1:0.3, and then carry out the first stirring, Aeration; using clam shells, slag and other organic and inorganic waste media to change the physical properties of the silt, changing the physical properties of the soil aggregate structure of the original silt from ext...

Abstract

The invention relates to a method for preparing plant nutrient soil, in particular to a method for preparing plant nutrient soil through utilizing city watercourse sludge. The method includes the following operating steps: crushed clamshells and slag as well as quick lime are sequentially spread on dehydrated sludge to form a mixture; decayed matters generated by fermenting and decaying mixed drug residues and fungus buds are spread on the mixture; the composition is composted and keeps warm, and the composting time varies along with different temperature; after a covering matter is removed, and the composting operation is continuously performed until the temperature inside the compost is the same as the atmospheric temperature, so that the plant nutrient soil is obtained. The method for preparing plant nutrient soil, superior to the traditional method for preparing plant nutrient soil, reuses watercourse sludge, waste drug residues and fungus buds, requires no large-area site during the composting process, shortens the compost forming time and is high in compost forming efficiency as three-time full stirring, aeration and composting operation are performed, besides, no secondary chemical pollution is caused due to zero addition of chemical agents.

Description

technical field [0001] The invention relates to a method for making nutrient soil for household potted plants, in particular to a method for making nutrient soil for household potted plants by using urban river silt. Background technique [0002] Urban river silt is rich in organic matter and nutrients needed for plant growth, but also contains harmful substances such as pathogenic bacteria and heavy metals. If the sludge can be converted into nutrient soil after harmless treatment and resource utilization in a short period of time, it can not only solve the problem that the greening cultivation substrate relies heavily on peat resources, but also save natural resources, prevent secondary pollution of the environment, and realize The virtuous circle of ecological economy is of great significance. [0003] The patent No. is 200910154961.7, and the Chinese patent titled "A Production Method for a Special Cultivation Substrate for Garden Plants" discloses a production method f...
