Abstract

The invention relates to the technical field of organic fertilizer preparation, and discloses a preparation method and device for preparing a bio-organic fertilizer from crop straws, and the preparation method comprises the following steps: drying the crop straws, and crushing; then feeding the straw powder into disinfection equipment for sterilization treatment, and sequentially cooling, draining, drying and crushing after the sterilization treatment is finished, so as to obtain straw powder; vinasse and mineral powder are utilized to prepare a premix; adding the straw powder, the wet chicken manure, the premix, the ardealite and the biological strain into the mixer, and fully mixing to prepare a granulated fertilizer; adding into a coating machine, spraying the coating liquid under the rotation of the coating machine, continuously rotating after spraying, and drying. The preparation device comprises a first granulation structure, a first conduction mixing structure, a stable connecting plate, a second conduction mixing structure and a second granulation structure, the preparation method disclosed by the invention is simple, low in cost and free of environmental pollution, particularly has the effects of restoring, retaining water and the like on soil in which chemical fertilizers are used for a long time, and improves the economic value of crops.

Description

technical field [0001] The invention relates to the technical field of organic fertilizer preparation, in particular to a preparation method and device for preparing biological organic fertilizer by using crop straws. Background technique [0002] Straw is a general term for the stem and leaf parts of mature crops. Usually refers to the remainder of wheat, rice, corn, potatoes, rape, cotton, sugar cane and other crops after the seeds are harvested. More than half of the products of crop photosynthesis exist in straw, which is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, etc. It is a multi-purpose renewable biological resource. It is characterized by high crude fiber content and lignin. Although lignocellulose cannot be utilized by pigs and chickens, it can be absorbed and utilized by livestock such as ruminants, cattle and sheep. [0003] According to Chinese Patent No. CN201911393904.4, the present invention discloses a method for remov...
