Embodiment 1

[0028] (1) Sub-high temperature anaerobic carbonization of biomass;

[0029] Take corn cobs, for example. The corn cob particles are sent into the movable combined high-efficiency biomass carbonization device (another invention of our company), and the carbonization is carried out under anaerobic conditions (carbonization time is 8H). When the temperature is heated above 150°C, the complex structure of the particles begins to decompose; when the temperature is greater than 260°C, the decomposition intensifies, and wood vinegar, wood tar and gas are generated; when the temperature reaches 450°C, it starts to be anaerobic and atomized, and black carbon particles. At the same time, use the gas condensation and purification system connected to the exhaust port on the carbonization device to recover the liquefied wood vinegar liquid tar mixture, and wait for natural cooling before use.

[0030] (2) Earthworms process livestock and poultry manure to obtain vermicompost;

Abstract

The invention discloses a biomass charcoal-based seedling growing matrix and a preparation method thereof. The biomass charcoal-based seedling growing matrix comprises, by volume, 35-45% of biomass charcoal, 25-35% of earthworm manure, 5-10% of pyroligneous liquor, 10-20% of perlite and 5-10% of vermiculite. Agricultural wastes such as cob, rice husk, peanut hull, straw and a domestic fungus matrix as main raw materials are subjected to high temperature anoxic carbonization to form the biomass charcoal. The biomass charcoal replaces base raw material turf commonly used in seedling growth so that a seedling growth cost is greatly reduced, over-exploitation of non-renewable resource turf is reduced, and ecological continuous development is kept. The agricultural wastes are reasonably utilized so that burning-caused environmental pollution is avoided and resource recycle is realized.

Description

[0001] technical field [0002] The invention belongs to the technical field of recycling of agricultural waste resources, and in particular relates to a seedling raising substrate using biomass charcoal as a raw material and a preparation method thereof. Background technique [0003] Seedling raising is an important technical link in vegetable production. The quality of seedlings directly affects the growth, yield and quality of vegetables. With the standardization, scale and specialization of vegetable production in my country, vegetable seedling cultivation has gradually changed from the traditional exclusive single-family soil seedling cultivation to industrial soilless seedling cultivation, thereby greatly improving the efficiency of seedling cultivation. At present, the substrate of soilless seedlings is usually composed of peat, vermiculite, perlite and the like. Peat is rich in organic matter (humus) and minerals. It is an ideal composite substrate material and is w...
