Method for preparing biological fertilizer and the biological fertilizer by the method

Abstract

The invention discloses a method for preparing a fertilizer by utilizing plant waste slag and the biological fertilizer prepared by the method, wherein the biological fertilizer is prepared by uniformly mixing the plant waste slag, organic wastes, salts, carbamide, thermophilic aerobic biological bacteria, adding the mixture into a fermentation tank for dehydrating and crushing after thermophilicfermentation. Compared with prior art, the method using thermophilic aerobic bacteria as production strains, overcomes long deodorization process in current traditional biofertilizer production and control difficulty in technique, and has the advantages of simple industrial process, short preparation time and low cost. The method is especially suitable for recycling the waste slag in Chinese medicine production, decreases pollution on environment, and achieves the purpose for turning rubbish into treasure. The prepared fertilizer is quick release and slow release, contains more than 60% of organic matters, and riches in nitrogen, phosphorus, potassium, crude protein, pure protein, amino acid, kinds of vitamins and trace elements.

Description

technical field [0001] The invention relates to a method for preparing organic fertilizer by using plant waste residue and the bio-organic fertilizer produced by the method, in particular to a method for using microorganisms to ferment plant waste residue to make organic fertilizer and the bio-organic fertilizer produced by the method. Fat. Background technique [0002] In recent years, people's awareness of environmental protection has increased, and they have begun to seriously consider reducing the amount of chemical fertilizers, developing organic agriculture, and establishing a green food safety engineering system. The application of organic fertilizers is a traditional experience in China's agricultural production. Until the 1950s and 1960s, most of my country's fertilizer resources still relied on organic fertilizers. After the 1960s, especially after the implementation of the contract responsibility system in rural areas, the amount of chemical fertilizers increased...

Problems solved by technology

The organic fertilizer formed by natural fermentation is basically through anaerobic fermentation, and the fertilizer smell is relatively strong, so it cannot be commercialized

Commercial fertilizers refer to fertilizers made by artificial fermentation using plant straw, livestock and poultry manure, and various organic materials. The current production process requires deodorization treatment. The main method is to add target microorganisms to the raw materials and use microorganisms to decompose Organic matter, changing macromolecular substances into small molecules, and then achieving the purpose of deodorization, decomposing, dehydration, and drying. Because the deodorization process is very long and the process is not easy to control, the application of biological fertilizers is affected.

[0004] At the same time, with the vigorous development of the pharmaceutical industry, especially traditional Chinese medicine, especially in the extraction and production of Chinese medicinal plants, a large amount of waste residue will inevitably be produced. If it is freely released in the environment, it will inevitably cause serious pollution to the environment. The waste residue produced after the extraction of licorice is one of them. If it is not treated, it will not only cause waste of resources but also cause environmental pollution. It is imperative to properly deal with it

[0005] However, the effective treatment of it has not been reported yet. The main research is the use of licorice residue to ferment and prepare edible fungi such as oyster mushrooms. However, it is quite difficult to reuse the waste residue produced thereafter. Preparation of coatings for pills, but small amounts are still difficult to solve the underlying problem
