The biofertilizer projects of livestock manure are mainly chicken manure, and its application technology is divided into two categories: one is to dry fresh chicken manure by drying and airing, which is a pure pursuit of the management of products with transport value, which violates the traditional technology of "stacking" of livestock manure since ancient times, and produces "dead fertilizer" without fermentation and decay heat. At present, it is widely used in a considerable range Use. The second is to use microbial fermentation technology to make feces mature and make an ecological organic fertilizer.
The process of microbial fermentation is to create a good condition for normal reproduction of microorganisms, promote microbial metabolism, accelerate the decomposition of organic materials in chicken manure, and fundamentally change the nature of chicken manure. It not only avoids the loss of nutrients, but also improves the quality of fertilizer.
Process flow of biofertilizer project
The technological process of biofertilizer can be divided into two technical routes: one is powdered bio organic fertilizer, the other is granular bio organic fertilizer
Technical route I:
Fresh chicken manure + straw powder (or other organic matter) + strain + regulator - Mobile windrow turner
- stacking fermentation - crushing - screening - drying - testing - packaging - sales
Technical route II:
Fresh chicken manure + straw powder (or other organic matter) + strain + regulator - Mobile windrow turner - crushing - screening - fertilizer matching - granulation (rotary drum granulator
) -air drying - testing - packaging - sales
The implementation advantages of biological fertilizer project are as follows:
(1) low investment, low cost and market competitiveness.
The process requires production in the workshop shed, and operation in the open air in dry area or season. Production is not limited by seasons. High degree of automation, low investment and low cost. The investment in basic equipment is about 30000 yuan. If the pelletizing equipment is to be increased by another 30000 yuan (small-scale) to 100000 yuan (large-scale). Four or five people can form a production capacity of more than 30 tons a day. The production cost of 30 tons is more than 150 yuan, and the power consumption per ton (excluding pelletizing) is less than 1 degree. The sale price of fertilizer has posed a challenge to drying and drying chicken manure.
(2) the bio organic fertilizer produced by this process has good quality and high efficiency. In particular, it improves the availability of nutrients. The problems of slow fertilizer effect, low utilization rate and low economic benefit in the same year were solved.
(3) effectively improve the fertility of cultivated land and the environment for soil supply. The extracellular polysaccharide overflowed by the living bacteria in the bio organic fertilizer is the binder of soil aggregate structure, which can loosen the soil, strengthen the soil aggregate structure, improve the ability of water and fertilizer conservation, and increase the soil organic matter.
