Embodiment

[0009] Embodiments: 1. Grinding: adjust the carbon-to-nitrogen ratio to about 20 after the straw is crushed.

[0010] 2. Noodle pile fermentation: adjust the moisture content of the fermented product to 60% with auxiliary materials, sprinkle the strains evenly on the surface of the fermented product, and use the ground walking type overturning machine to stir evenly; pile the fermented product into a width of 1.5-2M, 0.8-1M high, in the shape of piles with unlimited length; the temperature rises to about 60°C, turn the pile once every 6-7 days, and ferment for 12-15 days. Fermentation effect: The fermented material is loose and odorless, which is conducive to the later deep processing.

[0011] 3. Sieving: After 12-15 days of fermentation, the water content is between 30% and 40%. Sieve the fermented product, which can reduce the crushing amount of the material.

[0012] 4. Crushing: Crushing the sieved materials.

[0013] 5. Premixing: add trace elements (zinc, boron, manga...

Abstract

The invention relates to the field of bioorganic fertilizers, and specifically relates to a method of preparing bioorganic fertilizer from crop straws. In the provided method, the raw materials are stacked on ground in long strips to be subjected to fermentation. The method comprises the following steps: adjusting the water content of raw materials to 60% by using auxiliary materials, evenly spraying bacterium strains on the surface of raw materials, evenly stirring by a ground-walking turnover machine, stacking the raw materials into strips with a width of 1.5-2 meters, a height of 0.8 to 1 meter, and a random length, turning over the strips for every 6-7 days after the temperature reaches 60 DEG C or so, then screening the fermentation products; grinding the screened fermentation products; extruding, and then granulating the grinded materials by an extruding and granulating machine so as to obtain the organic fertilizer granules. In the provided technical scheme, the production of bioorganic fertilizer matrix is accomplished by a high efficient biological conversion technology; the straws can be completely decomposed within 7-10 days by adding bacterium strains into organic materials, and the method has the characteristics of short composting period, little loss of fertilizer efficiency, high humic acid content in compost, efficient removal of odor, efficient elimination of pathogenic bacteria in organic materials, and complete innocent treatment.

Description

technical field [0001] The invention relates to the field of bio-organic fertilizers, and relates to a method for preparing bio-organic fertilizers from crop stalks. Background technique [0002] Fertilizer is an important material basis for agricultural development. In my country, the promotion of chemical fertilizers has played a key role in increasing agricultural production and income. However, due to the long-term, excessive, and single application of chemical fertilizers, the lack of organic fertilizers, the imbalance of various nutrient ratios, and the low utilization rate of chemical fertilizers have caused farmland ecological problems. The environment and soil microbiota have been damaged to varying degrees. This method of increasing production at the cost of increasing input and excessive consumption of soil has made it difficult to maintain ecological balance and has begun to bring risks of reduced production. It has also affected the quality of agricultural produc...
