Organic microorganism-containing ecological fertilizer and production method thereof

Abstract

The invention discloses an organic microorganism-containing ecological fertilizer and a production method thereof. The ecological fertilizer consists of a three-layer structure, an inner layer is made of compound fertilizer granules, an urease inhibitor and nitrification inhibitor coating is used as a middle layer, an outer layer is made of an organic microorganism coating agent prepared by using an active bacteria packing method; and the production method comprises the steps of mixing and granulating, inhibitor coating, and organic microorganism coating. The production method disclosed by the invention is simple, and a prepared ecological fertilizer is complete in nutrients, ensures a high survival rate due to mixed bacterial manures, ensures long survival time of effective living bacteria, has sufficient inorganic nutrients, is convenient to apply, can avoid topdressing, and promotes the development of non-toxic and harmless fertilizers; and the ecological fertilizer has an obvious antagonism effect on continuous cropping pathogenic fungi, therefore, the proliferation of bacteria is effectively promoted, the micro-ecological environment of soil is significantly improved, and after the crops are harvested, the soil is fertile so that next-stubble crops can grow very well.

Description

technical field [0001] The invention belongs to the technical field of organic microbial compound fertilizer production, and in particular relates to an ecological fertilizer containing organic microorganisms and a production method thereof. Background technique [0002] The carbon-to-nitrogen ratio of fertile soil should be 25:1, but according to surveys, the current soil carbon-to-nitrogen ratio is 8-10:1, and there are about 111 million microbial strains in 1g of soil, of which beneficial strains only account for 2-5%, the harmful bacteria are more than 3 times higher than the beneficial bacteria, and 80-90% of the harmful bacteria only consume nutrients and do not work. There are few original beneficial bacteria in the soil, which decompose organic matter, synthesize humic acid, and transform insoluble minerals in the soil. Material nutrients and nitrogen fixation are weak. Among the fertilizers currently on the market, organic fertilizers, biological fertilizers, and ...

Problems solved by technology

In this process, the fertilizer particles used in the inner layer are organic fertilizers or chemical fertilizers. When organic particles are used in the inner layer, the organic matter can be used as a carrier for microorganisms, but it does not provide a large number of elements such as nitrogen, phosphorus, and potassium required by plants. When the inner layer uses chemical Fertilizer, refined dry powder spores have no vegetative growth carrier, and are directly coated on the surface of the fertilizer, which is easily killed by the acidity and alkalinity of the fertilizer itself, causing the biological bacteria coated on the surface of the granular fertilizer to have no nutrient carrier, and are extremely strong in acidity and alkalinity. It is difficult to survive on the surface of fertilizer granules. In addition, the biological bacteria are purified and made into a powder with a bacterial count of 18 to 20 billion per gram, which is not easy to achieve in actual production.
