[0053] 1. The main raw materials of organic solid waste:

[0054] Dewatered sludge 75kg (dry weight basis).

[0055] 2. Preparation of biotransformation derivatives:

[0056] Use one of wheat straw, rice straw, corn straw, wood chips, beet stalks or their mixture with a diameter of 1cm after crushing to take 15kg (dry weight basis) and one or two mixtures of dewatered sludge and kitchen waste, take 85kg (dry weight), control the water content to 50%-65%, carry out the product of aerobic high-temperature biotransformation for 20-30 days, then carry out particle size sorting, and get the components whose particle size is less than 0.5cm to be biotransformed into Derivatives.

[0057] 3. Preparation of fermented biomass multifunctional soil conditioner

[0058] Take 75kg (dry weight) of dewatered sludge and 25kg (dry weight) of biotransformation derivatives and mix them to achieve the nutrient source required for the optimal growth and metabolism of aerobic microorganisms. The ...

Embodiment 2

[0061] 1. The main raw materials of organic solid waste:

[0062] Kitchen waste 75kg (dry weight basis).

[0063] 2. Preparation of biotransformation derivatives:

[0064] The preparation steps of the biotransformation derivatives in Example 1 are the same.

[0065] 3. Preparation of fermented biomass multifunctional soil conditioner

[0066] Use 75kg (dry weight) of raw material kitchen waste and 25kg (dry weight) of biotransformation derivatives to achieve the nutrient source required to regulate the optimal growth and metabolism of aerobic microorganisms, and place them in a 30-35°C incubator to domesticate the derivatives The beneficial microorganisms and their native microorganisms co-exist and carry out aerobic biotransformation for 15-17 days, turn over once every three days to make the small molecular substances directional humify, stack retting for 3-5 days, and the matured products are dried by natural wind Or dry at 25-45°C in a blast drying oven, and then pulver...

Abstract

The invention provides a fermented biomass multifunctional soil conditioner, and a preparation method and application thereof. The soil conditioner comprises the following main components in terms ofdry weight: 320-700 g / kg of organic matters, 7-25 g / kg of total nitrogen, 150-350 g / kg of humus, 3-15 g / kg of available phosphorus and 3*10<4> to 6.7*10<7> CFU / g of beneficial bacteria. The preparation method comprises the following steps: adding a biotransformation derivative into organic solid waste, and performing aerobic high-temperature biotransformation, stack retting, drying and crushing byusing a physicochemical-biological enhanced rapid aerobic biological fermentation method, thereby obtaining the fermented biomass multifunctional soil conditioner. The soil conditioner can be appliedto improvement and remediation of barren, degraded and salinized soil and soil with continuous cropping obstacles, and has the effects of obviously improving the physical and chemical properties of the soil, enhancing the soil permeability and improving a soil structure; the soil conditioner neutralizes the acidity and alkalinity of the soil, improves the microflora structure of the soil, and hasremarkable effects on crop growth and development and other aspects; and the fermented biomass multifunctional soil conditioner has the advantages of waste resource utilization, remarkable ecologicalbenefits and economic benefits and the like.

Description

technical field [0001] The invention belongs to the technical field of soil improvement and restoration, and relates to a fermented biomass multifunctional soil improver and a preparation method thereof, as well as the application of the improver in improving barren, polluted and degraded soil, and a soil improvement method. Background technique [0002] As a medium for plant growth, soil is inseparable from plant growth. Soil fertility is the core of soil, and soil quality determines the growth of plants. Due to the strong impact of human activities, the physical and chemical properties of soil have changed, such as high pH value, low organic matter content, lack of available nutrients, soil compaction, continuous cropping obstacles, etc. Among them, soil pollution and the degradation of its physical properties are the most common and seriously affect the normal growth of plants. Improving the physical structure and fertility of the soil can not only enhance the soil struc...
