Problems solved by technology

More than half of the photosynthetic products of crops exist in straw, which is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, etc., and is a multi-purpose renewable biological resource. Straw is also a roughage. The use of buckwheat stalks is still relatively small, resulting in a lot of buckwheat stalks piled up in the farmland, and no one buys them. Therefore, it is of great practical significance to develop wet waste and buckwheat stalk resource utilization technologies

Abstract

The invention relates to the technical field of agricultural fertilizers, and concretely relates to a preparation method of an environmentally-friendly bioorganic fertilizer, and the bioorganic fertilizer prepared therethrough. The preparation method of the environmentally-friendly bioorganic fertilizer comprises the following steps: pretreatment, mixed fermentation and production of the bioorganic fertilizer, wherein the pretreatment comprises: chopping and grinding of transported buckwheat straws, overturning drying, sterilizing and disinfecting, and cutting and crushing of transported wet garbage. A mode of primary fermentation, secondary fermentation and third beneficial microorganism addition is used to obtain the bioorganic fertilizer which is high in activity, long in storage time and rich in selenium element, so the problems of wet garbage and treatment are solved, a new treatment mode is provided for the recycled buckwheat straws, the production cost of the bioorganic fertilizer is reduced, and good social benefits and economic benefits are achieved; and the prepared product has the advantages of low cost and high fertility, can meet the requirements of agricultural plantation, and is worthy of wide promotion.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a method for preparing an environment-friendly bio-organic fertilizer and the prepared bio-organic fertilizer. Background technique [0002] There are a large number of growth-promoting bacteria in the rhizosphere of plants, such as phosphate-dissolving bacteria, nitrogen-fixing bacteria, plant hormone-secreting bacteria, and pathogenic antagonists. Green agriculture advocates the production of safe and pollution-free green food. In the process of producing green food, it is required not to use chemical fertilizers or chemical pesticides as little as possible. Although many bio-organic fertilizers in the prior art have been applied to agricultural production practices, most bio-organic fertilizers are far less effective than chemical fertilizers due to unreasonable strain composition or improper preparation operations. Therefore, the market acceptance very low....
