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;
s2: fermentation treatment
Mixing the livestock manure collected in the step S1 with the crushed crop raw material mixture, then sending the mixture into a fermentation area for fermentation treatment, aging and stacking the mixture again after the fermentation treatment is finished, and crushing the mixture after the aging and stacking treatment to obtain crushed raw materials;
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.
And S2, aging the livestock and poultry manure and crop raw material mixture after fermentation treatment for 15-23 days, and crushing the mixture after aging stacking treatment by a crusher, wherein the crushed particle size is 120-140 meshes.
Wherein, reasonable collocation of the fineness of the raw materials is important for the production process flow of the organic fertilizer. The higher the fineness of the raw material, the better the viscosity, and the higher the surface finish of the granulated particles. However, in the production process, the problems of overlarge particles, irregular particles and the like caused by the fact that the viscosity is too good are easily caused by the use of the super-proportion high-fineness material.
In the S3 step, the trace mineral elements of nitrogen, phosphorus and potassium are respectively pure nitrogen, phosphorus pentoxide and potassium chloride, and the use ratio of the crushed raw materials to the trace mineral elements of nitrogen, phosphorus and potassium is 45:1:1:3.

In the step S4, the time for the organic fertilizer particles to enter a dryer for drying and shaping is 10-12min, the drying temperature is 70-85 ℃, the organic fertilizer particle cooling and shaping equipment is a circulating air cooler, and the cooling and shaping time is 8-12min.
And S5, crushing the unqualified organic fertilizer particles by a crusher, returning to the disc granulation again for re-granulation, and drying, shaping and cooling the granulated organic fertilizer particles and screening.
After a series of preparation processing steps, the particle size of the organic fertilizer particles is 3-4 mm, the water content of the organic fertilizer particles is less than or equal to 5%, the organic matters are less than or equal to 45%, the total nutrient is more than or equal to 5%, and meanwhile, the quality standard of the organic fertilizer is implemented by referring to national implementation standard NY 525-2021.
Embodiment two:
the embodiment of the application provides analysis and comparison of the using effect of the organic fertilizer prepared by the first processing and the normal chemical fertilizer.
Two planting lands with the same size and the same fertility, water content and positive degree are selected, and are named planting land A and planting land B respectively, the planting crop is corn, the planting land A uses the organic fertilizer prepared in the embodiment, the planting land B uses the Dabei agricultural compound fertilizer, and the using amount of the Dabei agricultural compound fertilizer in the planting process is consistent, so that the planting land is comparable.
The growth heights at 60 days, 90 days and 120 days of fertilized growth in the planting land a and the planting land B were collected, and the hardening condition of the soil thereof was checked after three years and five years of repeated planting of the planting land a and the planting land B.
The collection of growth height data is a height average of 5 corn plants randomly selected within the planting field.
The specific test information data are shown in table 1:
TABLE 1
As can be seen from the test data information in Table 1, when the test site A of the organic fertilizer prepared by the preparation method of the application is compared with the test site B of the chemical compound fertilizer, under the condition of the same planting condition, the corn plants grown in the test site A are 10-30cn higher than the corn plants grown in the test site B in height comparison of crops in 60 days, 90 days and 120 days, and the soil of the test site A is not hardened when the corn plants are repeatedly planted for three years and five years, and on the contrary, the soil of the test site B gradually becomes hardened after three years, so that the organic fertilizer prepared by the preparation method of the application has obvious advantages compared with the common chemical compound fertilizer, and can be popularized and used.
