Embodiment 1

[0045] Present embodiment adopts following method to carry out composting:

[0046] (1) Put the kohlrabi with a moisture content of 80% into a wet crusher, and pass through a 20-mesh filter screen after being broken into a slurry;

[0047] (2) Then mix the pulped kosher, chicken manure with a moisture content of 20% and wood chips with a moisture content of 10% in a mass ratio of 3:2:1 to form a mixed raw material with a moisture content of 65%. The carbon-to-nitrogen ratio is 20:1, stir evenly;

[0048] (3) Turn the mixed raw materials into a sealed heat preservation device, carry out aerobic fermentation at 50°C, aerate once every 2 days, and form compost semi-finished products after 6 days;

[0049] (4) Transfer the semi-finished compost to the compost room, pile it into a conical shape and maintain proper ventilation, carry out secondary fermentation, turn the compost every 3 days, and form the finished compost after 20 days.

Embodiment 2

[0051] Present embodiment adopts following method to carry out composting:

[0052] (1) Throwing P. spicaculata with a water content of 99% into a wet crusher, crushing it into a slurry and passing through a 100-mesh filter screen;

[0053] (2) Then, mix the pulpy P. spicaculata, chicken manure with a moisture content of 40% and wood chips with a moisture content of 20%, and the mass ratio is 8:7:5 to form a mixed raw material. The moisture content of the mixed raw material is 70%, and the carbon The nitrogen ratio is 40:1, stir evenly;

[0054] (3) Turn the mixed raw materials into a sealed heat preservation device, carry out aerobic fermentation at 80°C, aerate once every 3 days, and form compost semi-finished products after 5 days;

[0055] (4) Transfer the semi-finished compost to the compost room, pile it into a conical shape and maintain proper ventilation, carry out secondary fermentation, turn the compost every 7 days, and form the finished compost after 30 days.

Embodiment 3

[0057] Present embodiment adopts following method to carry out composting:

[0058] (1) Throwing 90% of water content into the wet-type crusher, breaking into a slurry and passing through a 60-mesh filter screen;

[0059] (2) Then mix the pulpy Smilax, chicken manure with a moisture content of 30% and wood chips with a moisture content of 15%, and the mass ratio is 5:5:3 to form a mixed raw material. The moisture content of the mixed raw material is 67%, and the carbon-nitrogen ratio 30:1, stir evenly;

[0060] (3) Turn the mixed raw materials into a sealed heat preservation device, carry out aerobic fermentation at 65°C, aerate once every 3 days, and form compost semi-finished products after 7 days;

[0061] (4) Transfer the semi-finished compost to the compost room, pile it into a conical shape and maintain proper ventilation, carry out secondary fermentation, turn the compost every 5 days, and form the finished compost after 25 days.

Abstract

The invention relates to a composting method for a submerged plant. The method comprises following steps: (1), a pulpy submerged plant, chicken manure and sawdust are mixed, and a mixed raw material is formed and uniformly stirred; (2) the mixed raw material is subjected to aerobic fermentation, and a semi-finished compost product is formed; (3), the semi-finished compost product is subjected to secondary fermentation, and a finished compost product is formed, wherein the mass ratio of the pulpy submerged plant to the chicken manure to the sawdust is (3-8):(2-7):(1-5). According to the method, the submerged plant is used for aerobic composting for the first time, and waste utilization of submerged plant residues is realized; the finished compost product has excellent quality, and organic matters, the total nutrient content and the like all meet the national standard; the production method is simple and environment-friendly, and the composting efficiency is high.

Description

technical field [0001] The invention relates to the technical field of composting treatment, in particular to a method for composting submerged plants. Background technique [0002] Composting refers to the process of promoting the conversion of biodegradable organic matter into stable humus by relying on microorganisms such as bacteria in nature under artificial control. Since ancient times, my country has a history of using plant residues and animal manure for retting and composting. At present, the composting technology is relatively mature. [0003] Aquatic plants have the function of purifying water quality. Since the 1960s, scholars at home and abroad have used plants for sewage treatment research. Among aquatic plants, since the whole plant of submerged plants is underwater, the adsorption capacity is large, and the treatment effect is the best. Therefore, in recent years, submerged plants have been widely planted and used for water purification, resulting in a larg...
