Embodiment 1

[0026] This embodiment provides a resource utilization method of livestock and poultry manure and straw, including the following steps:

[0027] (1) Obtaining hydrolyzate of livestock and poultry manure

[0028] The livestock and poultry manure is irradiated with microwaves to obtain a hydrolyzate of the livestock and poultry manure containing polypeptides and polysaccharides, wherein the microwave frequency is 500 MHz, the hydrolysis time is 120 minutes, and the hydrolysis temperature is 130° C.

[0029] (2) Obtaining straw acid hydrolysis products

[0030] The straw was crushed to 0.1mm, put into the acid solution, and treated with microwave irradiation at the same time, and finally the solid was collected after solid-liquid separation, and dried at 100°C for 1 hour to obtain the straw acid hydrolysis product. Among them, the acid solution is one or more mixtures of acetic acid, lactic acid, citric acid, oxalic acid, hydrochloric acid and sulfuric acid with a volume concent...

Embodiment 2

[0046] The present embodiment provides a kind of preparation method of crop cold protection agent, comprises the following steps:

[0047] (1) Obtaining hydrolyzate of livestock and poultry manure

[0048] The livestock and poultry manure is irradiated with microwaves to obtain the hydrolyzate of the livestock and poultry manure containing polypeptides and polysaccharides, wherein the microwave frequency is 5000 MHz, the hydrolysis time is 15 minutes, and the hydrolysis temperature is 50°C.

[0049] (2) Obtaining straw acid hydrolysis products

[0050] The straw was crushed to 0.5 cm, put into the acid solution, and treated with microwave irradiation at the same time, and finally the solid was collected after solid-liquid separation, and dried at 50°C for 10 hours to obtain the straw acid hydrolysis product. Among them, the acid solution is one or more mixtures of acetic acid, lactic acid, citric acid, oxalic acid, hydrochloric acid, sulfuric acid with a volume concentration ...

Embodiment 3

[0064] The present embodiment provides a kind of preparation method of crop cold protection agent, comprises the following steps:

[0065] (1) Obtaining hydrolyzate of livestock and poultry manure

[0066] The livestock and poultry manure is irradiated with microwaves to obtain a hydrolyzate of the livestock and poultry manure containing polypeptides and polysaccharides, wherein the microwave frequency is 2000 MHz, the hydrolysis time is 80 minutes, and the hydrolysis temperature is 80°C.

[0067] (2) Obtaining straw acid hydrolysis products

[0068] The straw was crushed to 0.1 cm, put into the acid solution, and treated with microwave irradiation at the same time, and finally the solid was collected after solid-liquid separation, and dried at 100°C for 1 hour to obtain the straw acid hydrolysis product. Wherein, the acid solution is one or more mixtures of acetic acid, lactic acid, citric acid, oxalic acid, hydrochloric acid and sulfuric acid with a volume concentration of ...

Abstract

The invention relates to a recycling method of livestock and poultry manure and straws, and a product, and belongs to the technical field of waste recycling and plant protection. A crop cold-resistantprotective agent is prepared on the basis of simultaneously realizing safe harmless treatment and recycling of wastes by taking the waste livestock and poultry manure and straws as raw materials andutilizing a technology of combining microwave acidolysis and microwave hydrolysis, and the preparation cost is low. The livestock and poultry manure and straw raw materials are decomposed into polysaccharides, polypeptides and micromolecular amino acids through microwave hydrolysis and acidolysis, nutrient input is provided for crops, and cold resistance protection is achieved. The microwave hydrolysis and acidolysis can also fully kill pathogenic bacteria and worm eggs and degrade antibiotics. In addition, the straws subjected to microwave acidolysis can adsorb and fix heavy metals in the livestock and poultry manure, so that the prepared crop cold-resistant protective agent is greener and more environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of waste resource utilization and plant protection, and in particular relates to a resource utilization method and product of livestock manure and straw. Background technique [0002] Livestock and poultry manure refers to a type of rural solid waste produced in the livestock and poultry breeding industry, including pig manure, cow manure, sheep manure, chicken manure, duck manure, etc. Animal excrement is rich in organic matter and nutrients such as nitrogen, phosphorus, and potassium, and can also supply calcium, magnesium, sulfur, and other minerals and trace elements required by crops to meet the needs of various nutrients during the growth of crops. It has been regarded as an important source of soil fertilizer by people. Due to the high content of antibiotics, heavy metals, germs, and insect eggs in livestock and poultry manure, some people currently use the fermentation liquid of livestock and poultr...
