Embodiment 1

[0023] (1) First mix 6-10 parts of vermicompost (water content is 37.84%) with 0-4 parts of fly maggot droppings (water content is 37.84%), then add 50 parts of deep well water, distilled water can also be used if possible; Stir at 1000 rm / min for 20 min at room temperature. After the mixture is precipitated, the supernatant is filtered through a 100-mesh filter.

[0024] (2) Clean the sediment according to the steps described in (1) again with the remaining deep well water, combine the filtrates and filter.

[0025] (3) Add 2 parts of urea, 3 parts of monoammonium phosphate, and 3 parts of potassium sulfate successively, and stir at 1000 rm / min for 10 min at room temperature to obtain a liquid fertilizer, and mix the liquid fertilizer with Lactobacillus acidophilus (bacteria number: IFFI06005) according to the mass ratio China Bacteria Preservation Committee) expansion culture solution was added at 9:1 to obtain a khaki organic liquid biological fertilizer.

[0026] (4) Chec...

Embodiment 2

[0028] Mix 0.8Kg of vermicompost (water content is 37.84%) and fly maggot droppings (water content is 37.84%) 0.2Kg, then add 5Kg of deep well water, stir at room temperature 1000rm / min for 20min, after the mixture is precipitated, the supernatant is 100 mesh Strainer filter. The remaining 5Kg of deep well water was used to clean the sediment according to the previous steps, and the filtrates were combined. Add 0.2Kg of urea, 0.3Kg of monoammonium phosphate, and 0.3Kg of potassium sulfate in sequence, stir at room temperature for 10 minutes at 1000 rm / min to obtain a liquid fertilizer, and expand the culture solution of Lactobacillus acidophilus (strain number: IFFI 06005, China Culture Collection Committee) 0.11Kg is added to obtain the organic liquid biological fertilizer of khaki; the pH value of the liquid fertilizer is checked with a pH precision test strip, and the sampling is carried out with a biological microscope to check the number of effective viable bacteria. The...

Embodiment 3

[0030] Mix 0.9Kg of vermicompost (water content is 37.84%) and fly maggot droppings (water content is 37.84%) 0.1Kg, then add 5Kg of deep well water, stir at room temperature 1000rm / min for 20min, after the mixture is precipitated, the supernatant is 100 mesh Strainer filter. The remaining 5Kg of deep well water was used to clean the sediment according to the previous steps, and the filtrates were combined. Add 0.2Kg of urea, 0.3Kg of monoammonium phosphate, and 0.3Kg of potassium sulfate in sequence, stir at room temperature for 10 minutes at 1000 rm / min to obtain a liquid fertilizer, and expand the culture solution of Lactobacillus acidophilus (strain number: IFFI 06005, China Culture Collection Committee) 0.11Kg is added to obtain the organic liquid biological fertilizer of khaki; the pH value of the liquid fertilizer is checked with a pH precision test strip, and the sampling is carried out with a biological microscope to check the number of effective viable bacteria.

Abstract

The invention relates to an organic liquid fertilizer prepared with residue produced in the breeding of maggots and earthworms, in particular to an organic liquid bio-fertilizer and a preparation method thereof. The fertilizer comprises the following materials in part by weight: 6 to 10 parts of earthworm feces, 0 to 4 parts of maggot feces, 1 to 3 parts of urea, 2 to 4 parts of monoammonium phosphate, 2 to 4 parts of lemery salt and 85 to 95 parts of water. The preparation method includes the following steps that: (1) 6 to 10 parts of earthworm feces (37.84 percent of water content) and 0 to4 parts of maggot feces (37.84 percent of water content) are first mixed, 50 parts of phreatic water is then added, stirring is carried out under the room temperature at 1000rm / min for 20min, and after the mixture is precipitated, supernate is filtered; (2) the precipitate is rewashed by the rest parts of phreatic water according to step 1, and filtrates are merged; (3) 2 parts of urea, 3 parts of monoammonium phosphate and 3 parts of lemery salt are sequentially added, and are stirred under the room temperature at 1000rm / min for 10min, and the liquid fertilizer and lactobacillus acidophilus amplifying culture solution are added according to the weight ratio of 9:1, so that the organic liquid fertilizer is obtained.

Description

technical field [0001] The invention belongs to the technical field of bio-organic fertilizer and its preparation process, in particular relates to the preparation of an organic liquid fertilizer by utilizing residues after breeding of fly maggots and earthworms, and at the same time includes a preparation method of the organic liquid bio-fertilizer. Background technique [0002] Organic fertilizer is an organic fertilizer that is processed from organic solid waste after microbial fermentation, deodorization and complete decomposition. At present, organic solids mainly include organic waste, straw, livestock and poultry manure, cake, agricultural by-products, solid waste from food processing, and insect manure. Organic liquid bio-fertilizer is the liquid part obtained through certain technological means after the fermentation of organic solids. [0003] The general situation of the research on making organic fertilizers by using fly maggot manure and vermicompost is as foll...
