preparation example Construction

[0040] Preparation examples of raw materials and / or intermediates Straw: The straw in this application can be corn straw, soybean straw, wheat straw, etc. This example specifically takes the wheat straw sold by Jiaxing Animal Husbandry Family Farm in Suiping County as an example for illustration.

[0041] Okara: The okara in this application is a by-product in the process of producing soybean milk or tofu. In this embodiment, the feed-grade okara sold by Jinan Xuzhou Chemical Technology Co., Ltd. is used as an example for illustration.

[0042] Rainwater: This application specifically takes the rainwater in Shanghai and Shandong in March as examples for illustration.

[0043] Preparation of fermentation broth:

[0044] Source: Bacillus subtilis was purchased from the freeze-dried powder of Bacillus subtilis from Shandong Yihao Biotechnology Co., Ltd., and the live bacteria content was ≥20 billion cfu / g; Phanerochaete chrysosporium freeze-dried powder, resource number BNCC190652...

Embodiment 1

[0052] A kind of composting method of agricultural solid waste, see figure 1 , including the following steps:

[0053] ①. Site construction:

[0054] Choose a place with sufficient light and good ventilation to build a fermentation site 2, combined with figure 2 , this embodiment establishes the XYZ coordinate axis, the positive direction of the X axis refers to the south, the reverse direction of the X axis refers to the north, the positive direction of the Y axis refers to the east, the reverse direction of the Y axis refers to the west, and the positive direction of the Z axis Refers to the top, and the reverse of the Z axis refers to the bottom;

[0055] The topography of the fermentation site 2 is higher than that of the surrounding flat land 1, and the ground of the fermentation site 2 has an inclination of 4-7° relative to the horizontal plane (plane parallel to the XY plane); in this embodiment, the inclination of 5° is specifically Example, and the west-facing sid...

Embodiment 2

[0064] Examples 2-3 On the basis of the method in Example 1, the mass ratio of straw scraps to bean dregs in the base material premixing step was adjusted. Wherein, the mass ratio of straw scraps to bean dregs in Example 2 is 7:1; the mass ratio of straw scraps to bean dregs in Example 3 is 8:1.

Abstract

The invention relates to the technical field of agricultural solid waste recycling, in particular to an agricultural solid waste composting method, a fertilizer product and application of the fertilizer product. The composting method comprises the steps of site construction, straw smashing, base material premixing, watering and wetting, strain inoculation and pile construction and fermentation, composting can be completed in a short time to obtain a corresponding fertilizer product, and the composting product can effectively improve the soil aggregate structure and increase the soil fertility and has high application value.

Description

technical field [0001] This application relates to the technical field of agricultural solid waste recycling, more specifically, it relates to a composting method for agricultural solid waste, fertilizer products and applications thereof. Background technique [0002] my country is a large agricultural country, which produces a large amount of agricultural solid wastes such as corn stalks, soybean stalks, and bean dregs every year, with an unutilized rate of 30%. Currently, the treatment of agricultural solid waste is generally incinerated in the fields, which in turn causes air pollution. [0003] For this reason, people use the method of composting and fermenting organic fertilizers by adding human and livestock manure and agricultural solid waste. First, the agricultural solids are crushed, piled up with water, and allowed to ferment naturally for about 20 days. Stuffy fermentation. When the temperature of the compost no longer rises, and gradually drops to normal tempe...
