Embodiment 1

[0029] Pig manure and chicken manure should be piled up separately, covered tightly to prevent rain, and edible fungus residues should be dried and pulverized. Take 600 kg of pig manure (moisture content 40%), 500 kg of chicken manure (moisture content 40%), 100 kg of edible fungus waste, 20 kg of superphosphate, 50 kg of fly ash, and 100 grams of "Renyuan" RW enzyme agent , after fully mixing, adjust the moisture content to 60-70% (no water can be squeezed by hand), pile the material in the fermentation tank to a height of 0.6-1.2 meters, turn the pile and increase aerobic fermentation when the temperature rises to 45°C, and the temperature rises to Turn the compost once a day at 60-70°C and control the temperature <70°C to continue fermentation for 5-7 days. The fermented material is dark brown and has no odor.

Embodiment 2

[0031] Take 400 kg of pig manure (moisture content 40%), 600 kg of chicken manure (moisture content 40%), 170 kg of edible fungus waste, 30 kg of superphosphate, 50 kg of fly ash, and 100 grams of "Renyuan" RW enzyme agent , after fully mixing, adjust the moisture content to 60-70% (no water can be squeezed by hand), pile the material in the fermentation tank to a height of 0.6-1.2 meters, turn the pile and increase aerobic fermentation when the temperature rises to 45°C, and the temperature rises to At 60-70°C, turn the compost once a day and control the temperature <70°C to continue fermentation for 5 days. The fermented material is dark brown and has no odor.

Abstract

The invention relates to an organic fertilizer and a preparation method thereof. The organic fertilizer is prepared by the following steps: with the livestock excrement added with ground edible fungi waste, calcium superphosphate, fly ash and fermentation bacterial agent as raw material, performing first fermentation, oxygenation fermentation and further fermentation, wherein the fermented material is black brown without stink; and drying the fermented material, granulating, filtering, checking and packaging. In the invention, the pig manure and fowl manure have relatively great diffidence in the content of multiple nutritional ingredients such as organic matters, nitrogen, phosphorus and potassium; and according to the needs for nutrient of different crops, the edible fungi waste is added and mixed according to different proportions. By adding the calcium superphosphate, the increase of compost temperature is promoted, the content of water-soluble NH(4, +)-N of compost is increased, the release of NH3 is effectively reduced, and the phosphorus content of organic fertilizer is increased. By adding the fly ash, the total nitrogen content is increased. The organic fertilizer provided by the invention has the advantages of convenient bacteria source, simple fermentation process, little generation of foul gas, thorough decomposition, complete composition, low cost and high performance.

Description

technical field [0001] The invention relates to a fertilizer, in particular to an organic fertilizer and a preparation method thereof. Background technique [0002] With the continuous deepening of economic reform in our country, the promotion of chemical fertilizers has played a key role in increasing agricultural production and income. The microbial flora has been greatly damaged, seriously affecting the quality of agricultural products. With the continuous improvement of people's living standards and the basic settlement of the problem of food and clothing, high-yield and high-quality agricultural products and hygienic and healthy food have become urgent needs in the current society and agricultural production. The demand for organic fertilizers in modern green and pollution-free agricultural production is increasing rapidly. [0003] At present, my country's organic fertilizer products can be roughly divided into three categories: 1. Organic-inorganic compound fertiliz...
