Problems solved by technology

[0002] my country is a large agricultural country. The survey results show that the theoretical resources of straw in my country are 840 million tons per year, and about 700 million tons of straw can be collected. The main varieties of straw are rice, wheat, corn, etc. In recent years, the comprehensive utilization rate of straw has been improved. It can only reach about 70%, and the straw is simply processed into feed, biogas, solidified or dry distillation. The utilization rate of the straw is low, and only about 80% of the nutrients in the straw can be used, and the traditional straw dry distillation The various components must be separated before they can be used in agriculture. The process is complicated and the cost is high. Therefore, a straw treatment method with high utilization rate is needed.

Embodiment 1

[0016] A preparation method of straw fertilizer, comprising the following steps:

[0017] (1) Collection and crushing: the straw is concentrated and crushed, with a length of 2~3cm, placed in the fermentation tank, and the straw is crushed;

[0018] (2) Straw fermentation: After expanding the culture of EM bacteria, the number of viable bacteria is 10 8 ~10 9 CFU / ml, add the culture medium to the fermentation tank, the addition amount is twice the weight of the crushed straw, mix well, and ferment at a constant temperature of 26°C for 8 days, decompose the macromolecular nutrients in the straw, degrade phenolic substances, and reduce wood tar content, promote the release of nutrients in the soaking solution, and the conditions are mild, save energy, filter, and obtain fermentation broth and fermented straw;

[0019] (3) Straw dry distillation: dry the fermented straw to a moisture content of 6-8%, crush it to 3-5mm, put it into a pyrolysis device, heat it to 300°C, and heat ...

Embodiment 2

[0024] A preparation method of straw fertilizer, comprising the following steps:

[0025] (1) Collection and crushing: the straw is concentrated and crushed, with a length of 2~3cm, placed in the fermentation tank, and the straw is crushed;

[0026] (2) Straw fermentation: After expanding the culture of EM bacteria, the number of viable bacteria is 10 8 ~10 9 CFU / ml, add the culture medium into the fermentation tank, the addition amount is twice the weight of the crushed straw, mix well, and ferment at a constant temperature of 27°C for 9 days to decompose the macromolecular nutrients in the straw, degrade phenolic substances, and reduce wood tar content, promote the release of nutrients in the soaking solution, and the conditions are mild, save energy, filter, and obtain fermentation broth and fermented straw;

[0027] (3) Straw dry distillation: dry the fermented straw to a moisture content of 6-8%, crush it to 3-5mm, put it into a pyrolysis device, heat it to 310°C, and h...

Embodiment 3

[0032] A preparation method of straw fertilizer, comprising the following steps:

[0033] (1) Collection and crushing: the straw is concentrated and crushed, with a length of 2~3cm, placed in the fermentation tank, and the straw is crushed;

[0034] (2) Straw fermentation: After expanding the culture of EM bacteria, the number of viable bacteria is 10 8 ~10 9 CFU / ml, add the culture medium to the fermentation tank, the amount added is 3 times the weight of the crushed straw, mix well, and ferment at a constant temperature of 28°C for 10 days, decompose the macromolecular nutrients in the straw, degrade phenolic substances, and reduce wood tar content, promote the release of nutrients in the soaking solution, and the conditions are mild, save energy, filter, and obtain fermentation broth and fermented straw;

[0035] (3) Straw dry distillation: dry the fermented straw to a water content of 6-8%, crush it to 3-5mm, put it into a pyrolysis device, heat it to 320°C, and heat up ...

Abstract

The invention mainly relates to the technical field of agricultural product and by product processing, and discloses a preparation method of a straw fertilizer. The method comprises the following steps: collecting and pulverizing straw; fermenting the straw; carrying out dry distillation on the straw and preparing the fertilizer. The method is simple, and fermentation treatment and dry distillation treatment are combined, and nutrient components in the straw are fully utilized, so that the utilization rate is up to 94.2 percent; wastes are turned into treasures, so that economic incoming of farmers is increased; after the straw is pulverized, EM bacteria culture liquid is added, after long-term fermentation, macro-molecular nutrient components in the straw are decomposed, phenolic compounds are degraded, the content of wood tar is reduced, and the release of the nutrient components into soaking liquid is promoted; moreover, a condition is mild, and energy conservation is achieved.
