Embodiment 1

[0045] Embodiment 1 The microbial compound fertilizer manufacturing device of the present invention

[0046] The device applied to the manufacture of microbial compound fertilizer consists of a compound granulation device and a pulping inoculation device (such as figure 1 Shown), the two are connected by a conveyor belt.

[0047] The pulping raw materials are weighed by the meter 1 and stirred evenly in the mixer 2, and the ingredients are sent to the pulping tank 4 of the pulping inoculation device with the bucket elevator 3 .

[0048]The slurry inoculation device is composed of a slurry tank 4, a slurry storage tank 5, a spray pump 6, a cylinder mixer 7, a low-temperature drying device 8 and a cooling system 9, and the slurry is discharged through the discharge valve at the bottom of the slurry tank 4. To the slurry storage tank 5, the bottom of the slurry storage tank 5 is connected to the spray pump 6, the nozzle of the spray pump 6 is in the upper part of the cylinder mi...

Embodiment 2

[0052] Embodiment 2 produces microbial compound fertilizer according to the method of the present invention

[0053] Bacillus licheniformis, Bacillus lateralosporus, Bacillus pumilus, Bacillus megaterium, and silicate bacteria were respectively cultured into spore powder, and the spore powder was mixed according to the proportion to obtain a compound bacterial agent. Add water to the pulping tank at a ratio of 1:5:100, so that the water content of the material mixture is 25-30%. Steam is introduced into the jacket of the outer wall of the pulping tank for heating, and the temperature in the pulping tank is controlled at 35-30%. At 40°C, stir the material with a stirrer to make a slurry; open the discharge valve at the bottom of the slurry tank, and put the prepared slurry into the slurry storage tank through the filter screen, and steam is also introduced into the jacket of the outer wall of the slurry storage tank for heating. Temperature, the temperature in the slurry storag...

Abstract

The invention provides a method for manufacturing microbial compound fertilizers, which comprises the steps of 1) cultivating the original strain to obtain compound microbial inoculum and mixing the compound microbial inoculum, a nutrient component and a strain carrier uniformly in proportion to prepare slurry, 2) mixing the rest raw materials in proportion, granulating, drying, cooling and then grading to obtain a compound granulated fertilizer, and 3) sprinkling the slurry into the compound granulated fertilizer for inoculation, drying at a low temperature, cooling, measuring and packaging to obtain the microbial compound fertilizer. The invention further provides a device for implementing the manufacturing method of the microbial compound fertilizer, which is composed of a compound granulation device and a slurrying inoculation device that are connected with each other by a conveyer belt. The manufacturing method and the device have the advantages that the microbial compound fertilizer produced by the method is high in content of total effective viable bacteria, high in strain activity, long in fertilizer efficiency period and good in economic benefit, has a function of a slow-release fertilizer, and can improve the soil and environment.

Description

technical field [0001] The invention relates to the preparation of microbial fertilizers, in particular to a method and device for producing microbial compound fertilizers. Background technique [0002] In recent years, due to the unreasonable application of chemical fertilizers and pesticides, a large amount of non-renewable resources have been consumed, and the soil structure has been destroyed, the environment has been polluted, the quality of agricultural products has been reduced, and human health and survival have been affected. [0003] As another important fertilizer source for agricultural production besides chemical fertilizers and organic fertilizers, microbial fertilizers have the following advantages: 1) It can provide crop nutrition, convert inorganic elements into organic compounds that are beneficial to plant growth, and increase nitrogen in the air or soil. 2) Reduce nitrogen deoxidation and oxidation process, reduce nitrate content, thereby improving crop q...
