Biological organic fertilizer using orange peel residue as main raw material and preparation method thereof

Abstract

The invention discloses a biological organic fertilizer using orange peel residue as a main raw material and a preparation method thereof. The biological organic fertilizer comprises the following raw materials in percentage by weight: 65 to 75 percent of orange peel residue, 5 to 8 percent of rice husk, 4 to 5 percent of wood dust, 0 to 5 percent of stevia rebaudiana filter residue, 10 to 20 percent of animal manure, and 1 to 2 percent of micro fertilizer and biological strains. The biological organic fertilizer is prepared by the steps of orange peel residue pretreatment, proportioning, primary degradation, compost ageing treatment, adding of biological functional bacteria at the rear end and the like. Various indexes of the biological organic fertilizer prepared by the method are totally superior to the biological organic fertilizer standards issued by the state; after the biological organic fertilizer is applied to the soil, the water, fertilizer, gas and heat conditions of the soil can be effectively improved, so that the soil becomes loose and fertile and is favorable for cultivation and growth and development of crop roots, the yield is increased, and the product quality is improved; the biological organic fertilizer is particularly suitable to be used as a special biological organic fertilizer for navel orange; and the industrial waste residue of orange juice is changed into valuable, the environment is protected, the comprehensive benefit is improved, and the invention has good economic benefit and ecological benefit.

Description

technical field [0001] The invention belongs to the field of bio-organic fertilizer production, in particular to a bio-organic fertilizer with citrus peel residue as the main raw material and a preparation method thereof. technical background [0002] In recent years, with the rapid development of my country's citrus industry, the orange juice processing industry has also risen rapidly in various places. The problem of waste disposal in the orange juice industry has become increasingly prominent. The traditional way of dumping and landfilling not only pollutes the environment, seriously threatens public safety, but also wastes resources. How to rationally utilize a large amount of waste residue is a key problem that the orange juice industry must face. The waste residue can only be fed to ruminants in a small amount in a fresh state as feed directly, and too much can easily lead to acidosis. The use of fermentation and drying technology to produce feed has good environmenta...

Problems solved by technology

The use of fermentation and drying technology to produce feed has good environmental protection effects, but it is technically feasible and economically unfeasible. Data show that drying 1 ton of waste residue requires 1 ton of coal, plus electricity, labor, and enterprise equipment depreciation. The cost remains high. Promotion is slow

There are also reports of using waste residues to prepare organic compound fertilizers, but they can only be added in a small proportion, generally no more than 40%, because waste residues usually have high water content (≥78%) and high crude fiber content (≥12.7%, based on dry basis weight ), low pH value (about 4.0), poor air permeability and other characteristics, these are the key factors hindering the preparation of organic fertilizer

The optimum humidity for bacteria fermenting organic fertilizer is 50-60%. Excessive water content will directly affect the fermentation speed and degree of maturity; the suitable pH value for bacteria is 6-8.5, and the acidic environment will directly hinder the growth of bacteria. species reproduction or even inactivation; organic fertilizer fermentation strains are mostly aerobic, and materials with poor air permeability will make it difficult to quickly and efficiently ferment
