Characteristics of chicken manure organic fertilizer:
1、 Because of its short digestive tract, chicken manure contains a large amount of organic matter. Chicken manure is used as organic fertilizer, which has good fertilizer utilization rate and high nutritional value.
2、 In the process of chicken manure fermentation, adding straw and other carbon substances not only improves the permeability of organic fertilizer, but also increases the content of C, which is of great help to crop production and carbon cycle.
3、 Chicken manure organic fertilizer has risen rapidly to reach the nutritional level of organic fertilizer without adding foreign fungicides and nutrients.
Technological characteristics of chicken manure organic fertilizer production line:
(1) The process of small chicken manure organic fertilizer equipment consists of raw material pretreatment system, fermentation system and fertilizer processing system, which can be flexibly combined according to the treatment capacity:
(2) The fermentation system adopts forced ventilation dynamic fermentation to ensure the adaptive supply of oxygen during the fermentation process, maintain the high activity and efficiency of microorganisms, and the product quality is stable. The general period is 15 days, and the aging period is 20 days. Compared with the traditional composting period of 60 days, the efficiency is obvious;
(3) The products of the small-scale chicken manure organic fertilizer production line project are highly harmless, with a removal rate of more than 99%, and completely decomposed. At the same time, the characteristics of raw materials are brought into play, and special products and market-specific fertilizers are developed according to the characteristics of local regions. The small-scale chicken manure organic fertilizer equipment meets the needs of marketization. The chicken manure organic fertilizer production line can be processed into refined fertilizer, improve output and increase efficiency, and promote pollution-free production. If chicken manure can be processed into organic fertilizer, it can not only effectively use chicken manure resources, but also not worry about sales.
Fermented chicken manure can be used directly as fertilizer or as raw material to produce compound organic fertilizer, which can thoroughly solve the environmental pollution problem caused by livestock manure and carcasses, and ensure the large-scale, green and sustainable development of the aquaculture industry.
