Description
Technical field
The present invention relates to a kind of method preparing soil conditioner using dealing with earthworm municipal sludge, belong to soil conditioner
Technical field.
Background technology
Municipal sludge refers to produced aqueous solid precipitate in city domestic sewage, During Industrial Wastewater Treatment Process
Matter, has the characteristics that moisture content is high, volatile material and ash are more, some municipal sludges also contain a large amount of pathogenic microorganisms with
The heavy metal of the pathogen such as parasitic ovum and some difficult degradations and toxic organic compound.Urban fallen leaves are primarily referred to as doing city
Produced fallen leaves when the vegetation of landscape is withered.In the Nature, Decomposition of leaf litter is the important of terrestrial ecosystems Nutrient Cycling
Link, discharges the nutrient needed for plant, shadow by decomposition
Ring soil organic matter to be formed and nutrient content.At present, the treatment approach of China's municipal sludge and the litter is mainly using defending
Raw landfill and anhydration and incineration, do not only take up a large amount of land resources, also can cause atmospheric pollution.
Lumbricuss, as one of maximum common monoid of soil animal, are the important substance decomposers of ecosystem, its function
To give full play to be the eucyclic strong guarantee of ecosystem material, there is the function of promoting Organic substance decomposition and inversion.Lumbricuss
The product urinary catheter of similar renal tubules organizes with similar hepatocellular body and its function of detoxification makes it have in environmental pollution improvement extensively
General purposes.Experiment shows, Lumbricuss can eat substantial amounts of organic substance during its metabolism, and it is mixed with soil
Close, decomposition and inversion is carried out by the biological chemistry action in the mechanical friction effect and intestinal of ballast.Dealing with earthworm can be in low one-tenth
Realize house refuse under this and the high efficiente callback of industrial waste utilizes.
Vegetable traditional cultivation with open ground soil cultivate based on, with scientific and technological progress gradually development and application facility soilless culture skill
Art, such as water planting, mist training, substrate training etc..Soil cultivation shortcoming be easy to occur continuous cropping obstacle disease, other soilless cultures due to
Operating technology is complicated, and host material preparation technique is difficult to grasp, high expensive, and the host material of application is difficult to meet produce need again
Will, thus constraining the development of industrialized agriculture.Facilities horticulture quickly grows in China, and facility planted area increases year by year, its life
Product tends to large-scale development.However, due to producing the restriction of cultivation condition and ordering about of economic interests, planting vegetable kind in facility
Class is single, continuous cropping phenomenon generally existing, and the generation of continuous cropping obstacle seriously constrains the sustainable use of soil in protected field.
Content of the invention
The technical problem to be solved: the generation for continuous cropping obstacle seriously constrains the sustainable of soil in protected field
Using problem, the invention provides a kind of method preparing soil conditioner using dealing with earthworm municipal sludge, the present invention with
Urban fallen leaves and municipal sludge are raw material, and fermentation reactor system is obtained fallen leaves sludge fermentation substrate, and cultivates Lumbricuss with it, collects Lumbricuss
Excrement and Lumbricuss soil, through air-drying, are pulverized, are mixed homogeneously with calcium superphosphate after sieving, prepared soil conditioner, then with corn straw,
Wood flour, Testa oryzae, cyanophyceae, glucose is raw material, and fermentation is obtained nutrient matrix, nutrient matrix and soil conditioner are mixed in proportion
Prepared soil conditioner.The raw material of the present invention is gathered materials on the spot, low cost, is stock using wormcast, straw etc., close to sky
So soil, buffer capacity is strong, there is not the contradiction between moisture, nutrient and oxygen, repeats and recycles, non-environmental-pollution
Residual, and provide desired nutritional composition can to the vegetable of different cultivars, the life of pathogen can be limited by the characteristic of wormcast again
Long, so that plant soil-borne diseases is inhibited.
For solving above-mentioned technical problem, the technical solution used in the present invention is:
(1) 3 ~ 5kg Urban fallen leaves, natural air drying are weighed, weighing the fallen leaves after 350 ~ 400g air-dries with 3.0 ~ 3.2kg moisture content is
The mud mixing that 80 ~ 85% municipal sewage plant's pressure filter are press-filtered out, in the environment for 0.5 ~ 1.2mg/l for the dissolved oxygen, controls
Temperature is 20 ~ 25 DEG C, keeps humidity to be 70 ~ 72%, fermentation reactor system 35 ~ 40 days, sludge fermentation of must falling leaves substrate；
(2) weigh 1 ~ 2kg above-mentioned fallen leaves sludge fermentation substrate to put in box for breeding, add 32 ~ 64g Lumbricuss, box for breeding is placed in
Cultivate and control cultivation the temperature inside the box to be 12 ~ 15 DEG C at lucifuge, after 1 ~ 2 day, spray a deionized water control chamber endogenous dampness
Spend for 75 ~ 80%, and collect wormcast, after culture 60 ~ 80 days, take out Lumbricuss, obtain Lumbricuss soil and wormcast；
(3) respectively by above-mentioned Lumbricuss soil, after wormcast natural air drying, add in pulverizer and pulverize, cross 100 mesh sieves, weigh 200 ~
250g sieve after Lumbricuss soil powder, 100 ~ 150g sieve after wormcast add batch mixer in, with 100 ~ 200r/min stirring
Mixing 3 ~ 5min, adds 3 ~ 5g calcium superphosphate, continues stirring 1 ~ 3min, obtains soil conditioner, standby；
(4) weigh 2 ~ 3kg corn straw, add in pulverizer after natural air drying and pulverize, cross 60 mesh sieves, weigh 600 ~ 700g and sieve
Maize straw powder afterwards, 50 ~ 150g wood flour, 70 ~ 100g Testa oryzae, 30 ~ 50g cyanophyceae, add 30 ~ 50ml mass after mix homogeneously
Fraction is 20% glucose solution, and at 35 ~ 40 DEG C, fermentation reactor system 20 ~ 25 days, obtain nutrient matrix；
(5) above-mentioned nutrient matrix is added in pulverizer and pulverize, cross 80 mesh sieves, the nutrient matrix powder after sieving and step
(3) soil conditioner prepared, 3:1 mix homogeneously in mass ratio, obtain soil conditioner.
The application process of the present invention is: in mass ratio for 2 ~ 4:1, by the soil conditioner of continuous cropping soil and present invention preparation
Mixing, mixed soil is used as vegetable growing, and vegetable growth is good, output increased 20 ~ 30%, and quality improves 10 ~ 15%, soil
In earth, pathogen reduces 40 ~ 50%.
The method have the benefit that:
(1) present invention preparation soil conditioner raw material gather materials on the spot, low cost, using wormcast, straw etc. be stock,
Close to natural soil, buffer capacity is strong, there is not the contradiction between moisture, nutrient and oxygen, repeats and recycles, acyclic
Border pollution residual；
(2) soil conditioner of present invention preparation provides desired nutritional composition can to the vegetable of different cultivars, again can be by Lumbricuss
The characteristic of excrement limits the growth of pathogen, so that plant soil-borne diseases is inhibited.
