Problems solved by technology

[0004] At present, when worm composting is used to treat livestock and poultry manure waste, they are either fully exposed to the air for a period of time to volatilize harmful gases such as hydrogen sulfide and ammonia, or pre-composted for several weeks to reduce the content of toxic and harmful substances. Live-dried livestock and poultry manure is air-dried, fermented and decomposed alone or mixed with other raw materials, and then composted for earthworm breeding. The pre-treatment of air-dried livestock and poultry manure occupies a large amount of land area, which is greatly affected by climate conditions and takes time and labor. Pre-decomposition treatment requires the introduction of other raw materials, which increases transportation costs, and composting fermentation requires raw material ratios, process management, and composting, which requires a certain amount of equipment and labor, which increases the tediousness and input costs of vermiculture. At the same time, the vermicompost produced, The nutrient content of vermicompost is low due to the absorption of nutrients by the feeding feces of earthworms. Most of the vermicompost cannot meet the nutrient requirements of the national standard organic fertilizer. , at about 50%, it needs to be air-dried to meet the water content standard of organic fertilizer, and a large number of beneficial microorganisms contained in it will die and cannot meet the standard of bio-organic fertilizer

Embodiment 1

[0039] A method of utilizing earthworms to process cow dung to produce bio-organic fertilizers, comprising the steps of:

[0040] The raw materials used in this method are as follows, parts by weight, and the following components are based on dry weight:

[0041] 80 parts of vermicompost, 10 parts of reed residue, 5 parts of biomass charcoal, 1 part of potassium fulvic acid, 1 part of amino acid, 1 part of medium and trace elements, 2 parts of microbial agent;

[0042] The amino acids described are animal source amino acids purchased from commercial sources. The amino acid is made from leftovers from various marine fish processing plants and cooking pulp water. It is processed by microbial fermentation, acid-base hydrolysis, and spray drying. It has moisture absorption and fermentation aroma. It contains 18 kinds of free amino acids, all amino acids The total amount is more than or equal to 70%, and it is easily soluble in water. The amino acids involved in the present invent...

Embodiment 2

[0070] A method of utilizing earthworms to process pig manure to produce bio-organic fertilizer, comprising the steps of:

[0071] The raw materials used in this method are as follows, parts by weight:

[0072] 75.5 parts of vermicompost, 15 parts of reed residue, 5 parts of biomass charcoal, 1 part of potassium fulvic acid, 1 part of amino acid, 0.5 parts of medium and trace elements, 2 parts of microbial agent;

[0073] The microbial agent is mixed with Bacillus subtilis, Bacillus licheniformis, Bacillus lateralis, and Bacillus colioids according to the number ratio of 2:1:1:1; the effective bacterial content of the microbial agent is ≥ 200 million / g;

[0074] The medium and trace elements are magnesium sulfate, zinc sulfate, borax, ferric sulfate, and ammonium molybdate mixed according to the mass ratio of 4:2:1:0.5:0.5;

[0075] In the process of preparing vermicompost, the components and proportions involved are as follows:

[0076] The weight ratio of earthworm speci...

Embodiment 3

[0082] The bio-organic fertilizer produced in embodiment 1 is used as the application effect of rice seedling raising matrix raw material:

[0083] (1) Experimental design

[0084] The test was carried out in April 2018 in a small shed at the Mapoling Experimental Site of the Institute of Agricultural Environment and Ecology, Hunan Academy of Agricultural Sciences. The bio-organic fertilizer produced by vermicompost is used as the raw material of rice seedling raising matrix, and three treatments are set up:

[0085] Control one (CK1): the seedling raising substrate sold in the market;

[0086]Contrast 2 (CK2): 30% of vermicompost, 35% of reed foam, 20% of peat, 10% of vermiculite, 5% of organic fertilizer (mass ratio) intermixed seedling-raising substrate;

[0087] Treatment one (T1): a seedling-raising substrate in which 30% of bio-organic fertilizer, 35% of reed foam, 20% of peat, 10% of vermiculite and 5% of organic fertilizer (mass ratio) of the present invention are mu...

Abstract

The invention belongs to the field of plant nutrition and fertilizer, and discloses a method for producing biological organic fertilizer by using earthworms to treat livestock manure waste. The main raw material used in the method is pretreated livestock manure, and the livestock manure waste is used as bio-organic fertilizer of earthworms and manure, which realizes resource utilization of the waste and develops the recycling agriculture and the recycling economy. A rice seedling breeding matrix prepared by using the bio-organic fertilizer of the invention can improve the quality of seedlings,prevent the occurrence of rice blight, is more suitable for rice transplanting, and promotes the growth of the seedlings in the field. The use of the bio-organic fertilizer of the invention in tea leaves improves the fertility of the soil and promotes the growth and development of a tea tree. The density of tea buds per area is 1.29 times higher than that of chemical fertilizer treatment, and theyield per area is increased by 56.25 percent; and the content of polyphenols and amino acids is high, the phenol to ammonia ratio is low, and the tenderness is good.

Description

technical field [0001] The invention belongs to the field of plant nutrition and fertilizers, and in particular relates to a method for producing bio-organic fertilizers by using earthworms to process livestock and poultry manure waste. Background technique [0002] With the rapid development of intensification, scale, and factoryization of the livestock and poultry breeding industry, the production of manure from the livestock and poultry breeding industry has also increased sharply, with an annual increase rate of more than 10%. In 2016, my country produced 3.8 billion tons of livestock and poultry manure. At present, it has become the main source of agricultural organic solid waste in my country. Because large-scale livestock and poultry manure is too concentrated and has a water content greater than 80%, and is affected by transportation, labor costs, and inability to digest on-site, it is piled up or discarded without treatment. The pollutants in these excrements (such ...
