Fragrant long-acting organic fertilizer based on sludge and lemon pomace

Abstract

The invention discloses fragrant long-acting organic fertilizer based on sludge and lemon pomace. The organic fertilizer comprises the following components in parts by weight: 100 to 150 parts of sludge, 50 to 100 parts of lemon pomace, 10 to 15 parts of oil cake residue, 5 to 10 parts of agricultural nitric acid rare earth, 20 to 30 parts of waste oil, 5 to 10 parts of milk, 5 to 10 parts of vinasse and 0.5 to 1 part of a microbial agent; the total concentration of the finished living bacterial of the microbial agent is 1.5*10<13> cfu / ml; the lanthanum content of the agricultural nitric acidrare earth is 35 mg / kg and the cerium content of the agricultural nitric acid rare earth is 50 mg / kg; the pH of the sludge is 8 to 9; and the water content of a mixture of the sludge of the lemon pomace is 30 to 40 percent. The fertility of the soil is improved by combining the sludge and rich nitrogen phosphorus potassium elements in the lemon pomace; furthermore, the stench of the sludge is overcome and the ascaris eggs are killed to 100 percent; and the validity period is increased to 36 months.

Description

technical field [0001] The invention relates to the field of odorless organic fertilizers, in particular to an aromatic long-acting organic fertilizer based on sludge and lemon pomace. Background technique [0002] Organic fertilizer is a carbon-containing material processed from biomass, animal and plant waste, and plant residues; it is rich in various nutrients, provides a comprehensive nutrient supply for crop growth, and can promote the reproduction of microorganisms and improve soil It is a long-term and environmentally friendly fertilizer with excellent physical and chemical properties. [0003] Municipal sludge is the residue after urban sewage treatment. A medium-sized city can discharge 100,000 tons of sludge every year. Therefore, how to use new development concepts to make green and effective use of municipal sludge is a hot topic of discussion. First of all, sludge is rich in nutrients and can improve the soil. Therefore, if the sludge can be effectively used in...

AI Technical Summary

Problems solved by technology

First of all, sludge is rich in nutrients and can improve the soil. Therefore, if the sludge can be effectively used in organic fertilizers, it will not only play a role in environmental protection, but also bring better economic benefits. , save the input of chemical components, but there are technical problems that must be solved when adding sludge as raw material to organic fertilizer. Sludge is generally in the form of colloid, has a foul smell, and also contains harmful bacteria such as pathogenic bacteria and parasite eggs, which are not conducive to ecology. How to ensure the utilization of sludge and kill the harmful substances in it is what we have to solve

[0004] Fruit is also a product that is consumed in large quantities in people's lives at present. The problem of the disposal of a large amount of residual pomace is becoming increasingly prominent, and the appearance of pomace is generally characterized by concentration and easy corruption. Dumping to landfill not only pollutes the environment but also wastes land and endangers public safety
