Embodiment 1

[0043] Preparation of organic garden mulch:

[0044] a. Pretreatment: crush landscaping waste and soybean straw to a particle size of 3-6cm, and crush penicillin mycelium, edible fungus waste, and furfural slag to a particle size of ≤2cm;

[0045] b. Primary fermentation: Mix 25kg of crushed landscaping waste and 15kg of soybean straw, add 2.34kg of penicillin mycelium, 8.5kg of water, and 5g of BM fermentation decomposer and mix evenly. At this time, the carbon-nitrogen ratio is 30 and the water content 60%, carry out forced ventilation static aerobic composting in a closed composting reactor, the initial ventilation rate is 0.30L / (min·kg), no turning operation is carried out during the composting process, fermentation is 7 days, and a fermentation product is obtained;

[0046] The experiment measured that the primary fermentation product had a pH value of 7.96, a water content of 36%, a carbon content of 51.98%, a nitrogen content of 2.83%, and a carbon-nitrogen ratio of 18....

Embodiment 2

[0051] Preparation of organic garden mulch:

[0052] a. Pretreatment: crush landscaping waste and corn stalks to a particle size of 3-6cm, and crush penicillin mycelium, edible fungus waste, and furfural slag to a particle size of ≤2cm;

[0053] b. Primary fermentation: Mix 24kg of landscaping waste and 12kg of corn stalks, add 2.7kg of penicillin mycelium; add 7.3kg of water, then add 5g of BM fermentation decomposer, mix well, and at this time the carbon-nitrogen ratio is 25, water content The yield is 55%, the forced ventilation static aerobic composting is carried out in the airtight composting reactor, the initial ventilation rate is 0.30L / (min·kg), the composting process does not carry out the turning operation, ferment for 5 days, and obtain the primary fermentation product;

[0054] The experiment measured that the primary fermentation product had a pH value of 7.88, a water content of 34%, a carbon content of 53.02%, a nitrogen content of 2.75%, and a carbon-nitrogen ...

Embodiment 3

[0059] Cover the soil with different mulches:

[0060] The organic covering is covered separately: the organic covering prepared by the method of Example 1 is spread on the bare ground of the scattered rose bushes, and the thickness of the laying is 50mm;

[0061] Straw mulching: The straw harvested in the current year is processed into a length of 50-150mm and spread on the bare ground of the scattered rose bushes, with a thickness of 50mm;

[0062] Gravel covering: Spread gravel with a specification of 20-30mm on the bare ground of scattered Chinese rose bushes, with a thickness of 50mm;

[0063] Ceramsite covering: spread the ceramsite with a particle size of 5-20mm and a water absorption of 5% on the bare ground of the scattered rose bushes, with a thickness of 50mm;

[0064] Covering in layers: the organic covering prepared by the method of Example 1 is tiled on the bare ground of the scattered rose bushes, and the thickness of the tiles is 30mm, and then the inorganic c...

Abstract

The invention provides a method for improving soil by using an organic garden mulch. The method comprises the following steps that 1, composting and decomposing treatment is conducted on garden greening waste, straw, wasted mycelia, edible mushroom waste and furfural residues, and the organic garden mulch is obtained after dyeing processing; 2, the organic garden mulch covers the leveled soil surface. By adopting the method, the phenomenon that the area of exposed ground of an urban garden is excessive can be improved, raising dust, dust particle adsorption and air pollution are reduced, water and soil loss and soil hardening of the exposed ground are avoided, a processing technology is simple in condition, the operating requirements are low, the appearance requirements can be met, and the acid-base property and the organic matter, nitrogen, phosphorus and potassium content of soil and a soil structure can be also improved.

Description

technical field [0001] The invention belongs to the technical field of soil improvement, and in particular relates to a method for improving soil by utilizing garden organic coverings. Background technique [0002] With the development of the country and the improvement of the level of urbanization, there are higher requirements for the living environment. However, urban gardens need to irrigate garden trees and large areas of lawns. Especially in northern cities, the city is short of water and is also attacked by sandstorms, which can easily make it difficult for surface plants to survive. When it rises, the sky will be full of yellow sand. Therefore, "water-saving gardens" are imperative. [0003] Soil is the foundation of plant growth, but urban garden soil has a tight surface, poor permeability, and low nutrient content, which seriously hinders the survival and growth of urban green plants. Zheng Yu et al. (2011) showed that the main reasons for urban landscaping soil...
