Problems solved by technology

[0004] Technical problem to be solved by the present invention: Aiming at the problems that the existing rice fertilizers are easy to harden the soil, destroy the soil structure, reduce the soil fertility, and the fertilizer absorption rate is low and the fertilizer efficiency is poor, a method for preparing rice with kitchen waste and fungus chaff is provided. In the method of fertilizer, the present invention obtains biochar by pyrolyzing chicken manure, and biochar is rich in micropores, which can provide habitats for soil microorganisms, protect them from predation, and provide nutrients required for microbial growth. Charcoal can not only supplement the organic matter content of the soil, but also effectively preserve water and nutrients, absorb heavy metals and toxic organic matter in the soil, improve soil fertility, and improve soil structure. Bacteria chaff, leftovers and biogas liquid are rich in protein , fat, nitrogen extracts and minerals can kill the germs and insect eggs in the common compost, and the composted material is rich in nutrients and absorbs quickly when it acts on rice, which can meet the needs of rice growth. Contains a variety of beneficial bacteria, which is conducive to the decomposition of organic matter in the soil and the absorption of crops

example 1

[0017] Take fresh chicken manure, manually clean out the stones and chicken feathers, weigh 1kg of chicken manure after removal of impurities and add it to the container, then add 10g of quicklime, stir and mix for 3min, place in an oven, and dry at 70°C until The moisture content of chicken manure is 8%. The pretreated chicken manure mixture is obtained and transferred to a muffle furnace. Under the protection of nitrogen, it is pyrolyzed at 300°C for 3h, and the heating rate is controlled at 20°C / min. After the product is cooled to room temperature with the furnace, take it out and place it in a ball mill for ball milling for 40 minutes, and pass through an 80-mesh sieve to collect the sieved material, namely biochar, for later use; weigh 1kg of corn stalks, 500g of cow dung and 2kg of fungus chaff Grinding in a pulverizer for 10 minutes, collecting the crushed matter, recycling 3kg of kitchen leftovers, and filtering, collecting the filter residue, adding the filter residue ...

example 2

[0020] Take fresh chicken manure, manually remove the stones and chicken feathers, weigh 2kg of chicken manure after removal of impurities and add it to the container, then add 20g of quicklime, stir and mix for 5min, place in an oven, and dry at 80°C until The moisture content of chicken manure is 10%. The pretreated chicken manure mixture is obtained and transferred to a muffle furnace. It is pyrolyzed at 400°C for 5h under the protection of nitrogen, and the heating rate is controlled at 30°C / min. After the product is cooled to room temperature with the furnace, take it out and place it in a ball mill for ball milling for 50 minutes, and pass through a 100-mesh sieve to collect the sieved material, that is, biochar, for later use; weigh 3kg of corn stalks, 600g of cow dung and 4kg of fungus chaff to add Grind in a pulverizer for 20 minutes, collect the crushed matter, recycle 4 kg of kitchen leftovers, and filter, collect the filter residue, add the filter residue and the cr...

[0023]Take fresh chicken manure, manually remove the stones and chicken feathers, weigh 1.5kg of chicken manure after removal of impurities and add it to the container, then add 15g of quicklime, stir and mix for 4min, then place in an oven and dry at 75°C When the moisture content of chicken manure is 9%, the pretreated chicken manure mixture is obtained, and transferred to a muffle furnace, and pyrolyzed at 350°C for 4 hours under the protection of nitrogen, and the heating rate is controlled at 25°C / min. After the decomposed product was cooled to room temperature with the furnace, it was taken out and placed in a ball mill for ball milling for 45 minutes, and passed through a 90-mesh sieve to collect the sieved material, i.e. biochar, for later use; weigh 2kg of corn stalks, 550g of cow dung and 3kg of fungus chaff Put it into a pulverizer and grind for 15 minutes, collect the crushed material, recover 3.5kg of kitchen leftovers, and filter, collect the filter residue, add t...

Abstract

The invention relates to a method for preparing rice fertilizer from kitchen waste and mushroom bran and belongs to the technical field of fertilizer manufacturing. Chicken manure is subjected to pyrolysis to obtain charcoal, the charcoal has rich micro-pores, and can provide a habitat for soil microorganisms, protect the soil microorganisms against predation and provide nutrient substances needed for growth of the microorganisms, the charcoal can replenish the content of organic substances of soil and can also effectively preserve water and nutrients, adsorb heavy metals and toxic organic substances in the soil, improve soil fertility and improve the soil structure, the mushroom bran, leftovers and marsh gas liquid contain rich protein, fat, nitrogen extract and mineral substances, during joint compost maturity, bacteria and eggs inside can be killed, and the composted materials are rich in nutrition, and can be absorbed rapidly when acting on rice and meet the requirements for growth of the rice, and contain multiple beneficial bacteria so that decomposition of organic substances in the soil and absorption of the crops can be promoted.

Description

technical field [0001] The invention relates to a method for preparing rice fertilizer by using kitchen garbage and fungus chaff, and belongs to the technical field of fertilizer production. Background technique [0002] The rice fertilizer is carefully prepared according to the soil and fertility conditions of each province, the characteristics of rice's fertilizer demand and absorption, and the application of international advanced balanced fertilization technology, comprehensive activation of nutrition technology, and the combination of the national soil fertility status and rice's demand for nutrients. Formulated to truly achieve "what is lacking, what is supplemented", with the most reasonable formula, to obtain the greatest benefit, to obtain the greatest benefit with the most reasonable formula. Through the use of special fertilizer for rice, my country's rice industry has more advantages, and it can participate in international competition with excellent quality and ...
