Embodiment Construction

[0012] The preparation method of this biomass sandy soil improver, its technical process is:

[0013] (1) Required materials:

[0014] Main material: Wood waste, such as sawdust, wood shavings, dead branches and residues from wood processing plants, etc., if dead branches, etc. can be crushed into wood chips with a particle size of less than 5mm to shorten the decomposition cycle.

[0015] Accessory materials: horse, donkey, mule dung, can be properly crushed (not into a lump).

[0016] Decomposing bacteria: isolate and extract decomposing bacteria white rot fungi, sulfonic acid bacteria, and pathogenic bacteria with strong enzyme activity from fallen (rot) wood in nature.

[0017] (2) Decomposing bacteria culture method:

[0018] ① Mother liquor formula (per 1000ml solution) required chemical reagents: use glucose 20g, peptone 5g, magnesium sulfate (MgSO 4 ·7H 2 O) 1.5g, potassium dihydrogen phosphate (KH 2 PO 4 ) 1.5g, manganese sulfate (MnSO 4 )50mg, zinc sulfate (Zn...

Abstract

The invention discloses a preparation method of a biomass sandy soil improving agent, which comprises the steps of: wetting sawdust, adding horse dung, uniformly mixing into a raw material, carrying out expanding propagation on a decomposer to be cultured into a mixed bacteria solution, diluting and spraying the raw material in for mixing; spraying a urea solution to the raw material, and uniformly mixing; introducing earthworms, degrading a coarse material again through swallowing, digesting and excreting of the earthworms, and spraying a horse dung layer above; after the earthworms enter the horse dung layer, stripping the horse dung layer containing the earthworms, and remaining the material, namely the biomass sandy soil improving agent. The preparation method is simple and easy to operate and low in production cost; and the prepared soil improving agent is capable of improving the content of the nutrition content and water retaining capacity of sandy lean soil to ensure that the sandy spoil is effectively improved, and has a remarkable effect.

Description

technical field [0001] The invention relates to a preparation method of a soil conditioner, in particular to a preparation method of a biomass sandy soil conditioner. Background technique [0002] Due to its poor nutrient, poor water holding capacity, and low productivity, sandy soil greatly restricts the productivity level of planting and the ability of vegetation recovery in sandy soil areas. Using woody waste (wood chips, etc.) as raw materials, it simulates the decomposition process of organic matter in nature, and completes the decomposition and humification process of biomass materials through the decomposition and transformation of microorganisms and earthworms within a period of time, making it similar to the "humus" in nature It is a kind of substance, which can improve its nutrient and moisture retention capacity after being mixed with aeolian sandy soil, and enhance the productivity of sandy soil. The purpose of improving the soil. Contents of the invention ...
