Method for organic fertilizer equipment to produce organic fertilizer by using stevia residue

2021/03/29
At present, stevioside production enterprises generally produce biogas by anaerobic fermentation together with industrial wastewater, and the biogas sludge produced is rarely used as fertilizer, and some even landfill it. The cost of waste leaf residue treatment is high, which causes great cost to the production enterprises, and the recycling rate of waste is very low, which can not fundamentally solve the problem of environmental protection. Fertilizer production line suppliers provide you with a cost-effective way to deal with waste.

Organic fertilizer production equipment uses stevia residue to produce organic fertilizer. Refined organic fertilizer contains a certain amount of organic matter in an all-round way. It has the effects of improving soil, balancing nutrition, promoting growth, resisting diseases and insect pests and increasing yield, and can improve the quality of crops. The use and promotion of organic fertilizers also meet the requirements of using fertilizers for green foods and pollution-free foods.

The moisture content of Stevia rebaudiana is high, and straw can be added to adjust the moisture content in the production process. Straw burning in place will cause serious air pollution, but also a huge waste of biomass resources. Adding straw into composted organic fertilizer after crushing by pulverizer can effectively regulate the moisture in compost, and increase the organic matter and mineral nutrients in compost, which can obtain better composting effect.

The specific operation is to use crushing equipment to cut crop stalks to an appropriate length, and then mix them with stevia leaf residue compost. The pile temperature can reach a certain temperature during the retting process, and it lasts for a long time, which can effectively kill the pests and eggs on the sugarcane leaves and prevent the pests from spreading to the crops during application.

It can also add the puffed chicken manure dried after high temperature disinfection to increase the content of organic matter in the substrate, increase the content of slow acting nitrogen in the substrate after fermentation, reduce the amount of available nitrogen in the cultivation process, reduce the content of NO3 - in crops, and make up for the shortcomings of high content of heavy metals in chicken manure fertilizer. The composting pattern is similar to that of natural composting.

The composted material can be processed by drum granulator.
