Embodiment 1

[0037] A kind of preparation method of liquid organic fertilizer in the present embodiment specifically comprises the following steps:

[0038] S1. Prepare ventilating particles and ventilating rods: the ventilating particles are basically as figure 1 As shown, a number of through holes a2 are opened on the hollow shell 1, and the shell 1 adopts a density less than 1g / cm 3 Made of plastic, such as a density of 0.89-0.93g / cm 3 low density polyethylene material. The outer surface of the housing 1 is covered with a cellulose film 3 covering all the through holes a2. In this embodiment, the cellulose film 3 can be a pineapple leaf cellulose film 3 .

[0039] Breathable pole 4 is basically as figure 2 As shown, the inside of the air-permeable rod 4 is axially provided with an air chamber 5, the top of the air chamber 5 is open, and the side wall of the air-permeable rod 4 is provided with some air holes 6, and the air hole 6 communicates with the air chamber 5 and the outside ...

Embodiment 2

[0051] The preparation method of a kind of liquid organic fertilizer in the present embodiment is compared with the preparation method of a kind of liquid organic fertilizer in embodiment one, the difference is: as Figure 5 and Figure 6 As shown, in step S1, the casing 1 is a cylindrical structure with both ends sealed, and the interior of the casing 1 is provided with an inner cylinder 19, which divides the interior of the casing 1 into two chambers 110, and the inner cylinder 19 A number of through holes b20 are opened on the side wall of the inner tube 19, and a cellulose film 3 is fixedly connected to the outer side wall of the inner tube 19, and the cellulose film 3 covers all the through holes b20 on the inner tube 19. In this embodiment, both the housing 1 and the inner cylinder 19 adopt a material with a density less than 1 g / cm 3 Made of plastic, such as a density of 0.89-0.93g / cm 3 low density polyethylene material.

[0052] In this embodiment, the inner cylinde...

Abstract

The invention relates to the technical field of liquid organic fertilizers, and particularly discloses a preparation method of a liquid organic fertilizer. The method comprises the following steps: 1)preparing ventilating particles: forming a plurality of through holes a in a hollow shell, and coating the outer surface of the shell with a cellulose membrane; 2) uniformly mixing the materials: mixing the plurality of ventilating particles with vegetable oil cake residues and a fermentation microbial inoculum to form a mixed material, wherein the fermentation microbial inoculum comprises Bacillus subtilis and Bacillus licheniformis; 3) fermenting materials: putting the obtained mixture into a fermentation tank, and fermenting the mixture; and 4) carrying out solid-liquid separation, and adding a preservative to obtain the liquid organic fertilizer. The ventilating particles are mixed in the vegetable oil cake residues, and air in the ventilating particles penetrates through the cellulose membrane and enters the vegetable oil cake residues in the fermentation process to provide oxygen for the fermentation microbial inoculum, so that the fermentation effect is improved, and the quality of the liquid organic fertilizer is improved. The shell in the method can be repeatedly used, so the method has the advantages of low cost and good effect.

Description

technical field [0001] The invention relates to the technical field of liquid organic fertilizer, and specifically discloses a preparation method of liquid organic fertilizer. Background technique [0002] Liquid organic fertilizer refers to liquefied organic fertilizer, and its nutrients come from animals, plants or natural minerals. Vegetable oil cake residue is a high-quality fertilizer raw material, rich in nitrogen, phosphorus, potassium and medium and trace elements, and is rich in resources, sustainable, and lower in raw material costs. However, when vegetable oil cakes are used as raw materials for production, since the vegetable oil cakes have undergone a pressing process, and the vegetable oil cakes have the characteristics of being fine and sticky, the air permeability of the vegetable oil cakes is insufficient, and the fermentation bacteria are aerobic. Fermentation is the main method, therefore, the fermentation effect of the vegetable oil cake residue will be ...
