Embodiment 1

[0034] The present embodiment provides a kind of processing method of biological organic fertilizer, comprises carrying out successively:

[0035] Mixing: mixing the raw materials to obtain a mixture, the mixture includes 10% to 20% of decomposed compost, 3-5% of additives and the rest of straw and animal manure, and the additives include 100 parts by weight of fermented strains , 1-3 parts by weight of ferrous sulfate, 10-20 parts by weight of Bacillus subtilis and 2-6 parts by weight of humic acid; One or more; the carbon-nitrogen ratio in the mixture is 25-40:1, the water content is 50%-60%, and the pH is 7-9;

[0036] Fermentation: Keep the oxygen concentration at 18-20%, the initial temperature is 18-25°C, after 1-2 days, the temperature gradually rises to 50-65°C, and keep it for 5-7 days to complete the fermentation

[0037] Crushing and screening: the particle size of the screened material is ≤1cm

[0038] Drying: drying at a temperature of 40-50°C to obtain bio-orga...

Abstract

The invention discloses a processing method of a bio-organic fertilizer. The method comprises the sequentially performed steps of mixing, fermentation, crushing, screening and drying. The mixing stepis performed before the fermentation; the raw materials are mixed to obtain mixed materials; the mixed materials comprise 10 to 20 percent of compost manure, 3 to 5 percent of additives and the balance of stalks and animal waste; the additives comprise 100 weight parts of fermentation strains, 1 to 3 weight parts of ferrous sulfate and 2 to 6 weight parts of humic acid. The organic fertilizer product meets the standard NY525-2012. The main index requirements are shown as follows: the organic matter content (metered by dry bases) is higher than or equal to 60 percent; the total nutrient (N+P2O5+K2O) content (metered by dry bases) is higher than or equal to 8 percent; the moisture (free water) content is lower than or equal to 30 percent; the PH is 5.5 to 8.0. The heavy metal content, the ascaris egg death rate and the colon bacillus value index in the organic fertilizer conform to the requirement of GB-8172.

Description

technical field [0001] The invention relates to the field of biological fertilizer processing, in particular to biological organic fertilizer and a processing method thereof. Background technique [0002] Fertilizer is the "grain" of crops. Only when fertilizers are applied in a balanced manner and soil nutrition is balanced, can crops grow vigorously. The soil needs to breathe like humans. The organic matter is the lungs of the soil. With sufficient oxygen, it is loose and breathable, and the root system is well developed, so the crops are naturally strong. [0003] Livestock and poultry manure is a good organic fertilizer. After harmless treatment, it is a high-quality organic fertilizer required by the soil. At present, the taste and quality of food are declining, and the long-term unbalanced fertilization has caused a serious shortage of organic matter in the soil, and the problems of soil acidification and compaction are prominent. However, the organic matter in the so...
