Problems solved by technology

However, due to the slow start of the ectopic fermentation process in my country, although it has been promoted by the Ministry of Agriculture, there are few specific studies on the ectopic fermentation process in organic fertilizers. Therefore, the research on ectopic fermentation processes in organic fertilizers is It has far-reaching significance for improving the fertilizer efficiency of organic fertilizers

Embodiment 1

[0022] In the present embodiment, a ectopic fermentation process of organic fertilizer, the method includes manure treatment, ectopic fermentation and subsequent treatment, the specific steps are as follows:

[0023] 1) Feces treatment: Add the collected feces, mainly pig manure, into a high-speed mixer, adjust the speed to 1000r / min, first carry out high-speed stirring for 12 minutes, measure the water content, and add urine to adjust the water content to 65 %, then add organic bentonite with a particle size of 100 mesh at one time, the addition amount is 2% of the feces and urine, stir at a high speed for 5 minutes at the same speed, stop stirring for 35 minutes; observe the state of the feces after the rest, and add the second time The particle size is 100 mesh organic bentonite, and the addition amount is 1% of feces and urine. After 4 minutes of high-speed stirring at the same speed, the measured and adjusted pH is between 7.5-8. This pH is conducive to the activity of sub...

Embodiment 2

[0027] This embodiment is the same as Example 1, except that the coconut shell particle size is 1 cm and the thickness is 40 cm in the present embodiment, the sepiolite powder particle size is 50 mesh, and the thickness is 20 cm, and the straw powder particle size is 100 mesh, and the thickness is 45 cm. The thickness of the rod slag is 20cm, the particle size of the zeolite powder is 100 mesh, the thickness is 15cm, and the amount of bacteria added is 800g / m 3 , the central temperature of the fermentation bed is 65°C, the oxygen content is 10%, and the humidity is 60%.

Embodiment 3

[0029] The present embodiment is the same as Example 1, except that the coconut shell particle size is 0.5 cm and the thickness is 50 cm in the present embodiment, the sepiolite powder particle size is 100 orders, and the thickness is 30 cm, and the straw powder particle size is 150 orders, and the thickness is 55 cm. The thickness of the fungus stick slag is 30cm, the particle size of the zeolite powder is 150 mesh, the thickness is 10cm, and the amount of bacteria added is 950g / m 3 , the central temperature of the fermentation bed is 65°C, the oxygen content is 10%, and the humidity is 60%.

Abstract

The invention discloses an ectopic fermentation process of an organic fertilizer and belongs to the field of organic fertilizer processing. The process comprises steps of dung disposal, ectopic fermentation and later treatment. According to the ectopic fermentation process, dung is pretreated by using methods of multiple times of stirring and organic bentonite addition, faeces and urea can be uniformly mixed through multiple times of stirring, the homogeneity and the viscosity of the dung can be improved by the bentonite on one hand, on the other hand, adverse odor of the dung can be removed under the adsorption action of the bentonite, pre-fermentation is firstly implemented by using a method that different padding materials are combined with fermentation in ectopic fermentation, a fermentation bed is activated, later fermentation can be facilitated, and meanwhile 'dead bed' can be prevented; different padding materials are beneficial to maintenance of oxygen contents in later fermentation processes on one hand, on the other hand, the ratio of C / N in the padding materials can be well maintained, fermentation can be well implemented with the combination of the different padding materials and fermentation, and the fermentation efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of organic fertilizer processing, and in particular relates to an ectopic fermentation process of organic fertilizer. Background technique [0002] The method of ectopic fermentation bed for manure treatment was introduced from Japan. The ectopic fermentation bed breeding technology has the characteristics of low pollution and environmental protection, and has become one of the models recommended by the Ministry of Agriculture. The ectopic fermentation bed is established to meet the needs of traditional pig manure treatment, and the ectopic fermentation bed is relative to the in situ fermentation bed. In the aspect of processing pig manure and urine to ferment and prepare organic fertilizer, the principle of ectopic fermentation bed is similar to that of in situ fermentation bed and composting, except that the ectopic fermentation bed is not used as a pig house to raise pigs, but as a solid fermentation tank...
