Problems solved by technology

[0004] The invention provides a method for preparing organic cultivation soil by utilizing agricultural organic waste, which solves the problem that aerobic composting in the prior art needs a suitable initial fermentation temperature, but it is limited in winter in the cold northern regions, and anaerobic composting due to its composting Long cycles and relatively low composting phase rates make it a limiting problem

Embodiment 1

[0035] A method of utilizing agricultural organic waste to prepare organic cultivation soil, comprising the following steps:

[0036] Step 1, pretreatment of raw materials

[0037] Step 1.1, mash the river sand, humus soil and garden soil respectively, mix them evenly according to the mass ratio of 1:1:2, and pass through a sieve with a mesh diameter of 2mm to obtain the mixed soil;

[0038] Step 1.2, crushing the agricultural organic waste into slag with a particle size of 0.8 mm, adding water therein, stirring evenly, and making the moisture content reach 55%, and obtaining the pretreated slag;

[0039] Step 1.3, drying the remaining sludge of the domestic sewage treatment plant to a water content of 55% to obtain pretreated sludge;

[0040] Step 2, the first mixed fermentation: add the pretreated slag, the pretreated sludge, urea, and aerobic microbial starter into the cellar at a mass ratio of 1500:200:10:1, and mix them evenly Ferment at room temperature, detect the tem...

Embodiment 2

[0052] A method of utilizing agricultural organic waste to prepare organic cultivation soil, comprising the following steps:

[0053] Step 1, pretreatment of raw materials

[0054] Step 1.1, mash the river sand, humus soil and garden soil respectively, mix them evenly according to the mass ratio of 1:1:2, and pass through a sieve with a mesh diameter of 2mm to obtain the mixed soil;

[0055] Step 1.2, crushing the agricultural organic waste into slag with a particle size of 0.5 mm, adding water therein, stirring evenly, and making the water content reach 60%, and obtaining the pretreated slag;

[0056] Step 1.3, drying the remaining sludge of the domestic sewage treatment plant to a moisture content of 60% to obtain pretreated sludge;

[0057] Step 2, the first mixed fermentation: add the pretreated slag, the pretreated sludge, urea, and aerobic microbial starter into the cellar at a mass ratio of 1000:300:20:1, and mix them evenly Ferment at room temperature. During the fer...

Abstract

The invention discloses a method for preparing organic cultivation soil by using agricultural organic wastes. The method comprises the following steps: pretreatment of raw materials, primary mixed fermentation, secondary mixed fermentation, aging and preparation of the organic cultivation soil. According to the method, by the use of the primary mixed fermentation and the secondary mixed fermentation, protein, saccharides, cellulose, hemicellulose, lignin and the like in the agricultural organic wastes are completely degraded into organic soil which can be absorbed by plants, and then sand, humus, garden soil and inorganic fertilizer are added into the organic soil, so that the prepared organic cultivation soil is high in void ratio, high in permeability, rich in nutrition and favorable for plant growth.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a method for preparing organic cultivation soil from agricultural organic waste. Background technique [0002] A large amount of agricultural organic wastes are produced every year in our country, such as straw, weeds, fallen leaves, fruit shells, etc. How to make rational use of these wastes is a very difficult task in the recycling and harmless treatment. Due to the lack of simple and effective utilization methods for agricultural organic waste, farmers often use the method of direct burning in the field to deal with agricultural organic waste in order to save labor and save time. Many toxic gases and a large amount of smog produced will also have a huge negative impact on people's normal production activities. Therefore, exploring the high-efficiency utilization technology of agricultural organic waste resources will have a significant impact on impr...
