Detailed Description
The technical solutions of the embodiments of the present application will be clearly and completely described below in conjunction with the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Embodiment one:
the embodiment of the application provides a preparation method of an organic fertilizer with multiple nutritional ingredients, which comprises the following preparation steps:
s1: raw material selection and matching
Recycling livestock and poultry manure to an poultry farm at regular time, carrying out centralized collection treatment, then removing crop straws, plant leaves and plant stalks from a planting field, crushing the collected crop straws, plant leaves and plant stalks by crushing equipment, and then carrying out centralized collection treatment to obtain a crop raw material mixture;

s3: mixing ingredients
Adding trace mineral elements such as nitrogen, phosphorus and potassium into the crushed raw material prepared in the step S2 in proportion, stirring and mixing the crushed raw material until the crushed raw material is uniform, adding the treated sludge fertilizer and cake fertilizer into the crushed raw material, and stirring and mixing the crushed raw material again until the crushed raw material is uniform to obtain an organic fertilizer raw material;
s4: granulating raw materials
Conveying the organic fertilizer raw material obtained in the step S3 into a disc granulator for granulation, drying and shaping the organic fertilizer particles by a dryer, and conveying the dried and shaped organic fertilizer particles into cooling equipment for cooling to obtain organic fertilizer particles with various nutritional components;
s5: screening package
And (3) sieving the organic fertilizer particles prepared in the step (S4) through a vibration sieving device, and packaging after the organic fertilizer particles meeting the requirements enter a coating machine to wrap and coat.
In the step S1, when the collected crop straws, plant leaves and plant stems are crushed, crushing equipment is one of a crusher or a hay cutter, and crushing grain grades are sieved by a sieve of 80-100 meshes.
Crop straw, stalk and leaf are one of important fertilizer varieties, and the crop straw, stalk and leaf contain N, P, K, ca, s and other essential nutrient elements.
In the step S2, when the livestock manure and crop raw material mixture is mixed and sent into a fermentation area for fermentation treatment, the fermentation area is in a sealed state, the fermentation treatment time is 5-7 days, and the fermentation temperature is 20-37 ℃.
And (3) directly feeding the recovered livestock and poultry manure into a fermentation area, and stacking through primary fermentation and secondary aging. Firstly, the odor of the livestock and poultry manure is eliminated. When in primary fermentation, the plant stalks such as straw, plant spitting sheets, weed powder and the like should be added in proportion, and fermentation strains should be added at the same time, so that coarse fibers in the plant stalks are decomposed, and the particle size requirement after crushing is in accordance with the particle size requirement of granulation production.
