Problems solved by technology

For a long time, the local people have used composting to ferment manure. Due to the low temperature, the composting temperature cannot reach the conditions to kill insect eggs, germs and weed seeds in the manure. The organic fertilizer produced will seriously pollute the soil after being applied to the soil. Spread weeds, pests and diseases, and affect the growth of crops

Embodiment 1

[0029] Example 1 The method for preparing biological carbonaceous organic matrix in high altitude area comprises the following steps:

[0030] ⑴Respectively remove impurities such as stones, rubble, metal, debris and soil clods mixed in cattle and sheep manure, make the dust content ≤ 4%, then crush them, pass through a 100 mesh sieve, and obtain cow dung particles with a water content ≤ 50% respectively and sheep dung pellets.

[0031] (2) Rapeseed is refined by conventional methods to obtain a cake-like material, which is steamed and crushed to 100 meshes to obtain oil cake powder.

[0032] (3) Crushing the fresh high-quality wheat straw of that year into a length of less than 0.5 cm to obtain wheat straw powder.

[0033] (4) Wheat straw powder pre-fermentation: Add 0.05% urea and 0.01% edible sugar to the wheat straw powder, mix well, and decompose at a temperature of 20°C for 35 days to obtain fermented wheat straw powder.

Abstract

The invention relates to a method for preparing a biological carbon organic matrix in high-altitude regions, which comprises the following steps: (1) removing impurities in cattle and sheep manure, pulverizing, and screening to respectively obtain cattle manure particles and sheep manure particles with the water content of at most 50%; (2) refining oil from rapeseeds by a conventional process to obtain a cake material, steaming the cake material, and pulverizing to obtain oilcake meal; (3) pulverizing current-year fresh high-quality wheat straws to obtain wheat straw powder; (4) prefermenting the wheat straw powder: adding urea and edible sugar into the wheat straw powder, uniformly mixing, and rotting to obtain the fermented wheat straw powder; (5) preparing a mixed fermentation microbial inoculum; (6) proportioning fermenting materials; (7) feeding into the tank, and fermenting to obtain a biological carbon organic matrix; and (8) pulverizing the biological carbon organic matrix, screening, naturally drying in air, assaying by a conventional process, and bagging the qualified product by a conventional process. The method can achieve the goal of quick biological high-efficiency fermentation.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for preparing biological carbonaceous organic substrates in high-altitude areas. Background technique [0002] In the high-altitude areas of Gansu Province, cattle and sheep manure resources are abundant. For a long time, the local people have used composting to ferment manure. Due to the low temperature, the composting temperature cannot reach the conditions to kill insect eggs, germs and weed seeds in the manure. The organic fertilizer produced will seriously pollute the soil after being applied to the soil. Spread weeds, pests and diseases, and affect the growth of crops. For this reason, how to make better use of cattle and sheep manure resources to produce high-quality organic fertilizers is particularly important. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for preparing biological ...
