Embodiment Construction

[0027]Naturally air-dry corn stalks and crush them to 5-10mm to obtain air-dried straws; naturally air-dry fresh cow dung and crush them to 5-10mm to obtain air-dried cow dung. Mix feces and ball mill for 10-20 minutes at a stirring speed of 400-500r / min to obtain the mixture. Put the mixture in a tube furnace and raise the temperature to 200-300°C at a heating rate of 5-10°C / min for 20 minutes. ~30min, then raise the temperature to 700~800℃ at a heating rate of 10~15℃ / min for 60~70min, and cool with the furnace temperature to obtain the green body, crush the green body, and grind it through a 200~230 mesh sieve, that is To obtain the base material, soak the base material in hydrochloric acid with a mass fraction of 5% for 30-50 minutes according to the mass ratio of 1:10, filter the filter residue, wash the filter residue with deionized water until it is neutral, and place the filter residue at a temperature of 60-80°C Dry in an oven to constant weight and cool to room temper...

Abstract

The invention relates to a preparation method of a high-efficiency environment-friendly seedling culture substrate, and belongs to the technical field of seedling culture materials. According to the method, straws and fresh cow dung are used as raw materials, and a low-temperature pyrolysis bio-carbon preparation technology is adopted to prepare the bio-carbon, so that the bio-carbon has an obvious carbon fixing effect and a promoting effect on soil fertilizer efficiency; the prepared bio-carbon has a rough surface, presents an uneven and honeycomb structure, has a developed hole structure with different hole diameters on the surface, and a part of carbon atoms form a stable lamellar graphite structure, so that the properties of the bio-carbon in application are kept relatively stable; thebio-carbon prepared by mixing the straws and the cow dung can prevent the pollution to the environment, has a good adsorption effect, and has the effect of water storage and fertilizer on the soil; according to the preparation method of the high-efficiency environment-friendly seedling culture substrate, penicillium and prepared bio-carbon are combined, high-efficiency and environment-friendly seedling culture substrate is prepared to promote the function of rhizosphere colonization and post-emergence growth promoting function of functional strains; the substrate has the advantages of high efficiency, broad spectrum, long-term, safety, no pollution and no residue.

Description

technical field [0001] The invention relates to a preparation method of a high-efficiency and environment-friendly seedling-raising substrate, and belongs to the technical field of seedling-raising materials. Background technique [0002] The earliest rudiments of factory production of plants appeared in protected gardening in Northern Europe. The industrial seedling cultivation of vegetables was gradually differentiated during the development of plant factory production, and has now formed an independent industry. In order to realize domestic modern agriculture in line with the world, industrialized seedling cultivation and industrialized production are inevitable trends. Among them, the most critical thing in industrial seedling cultivation is the selection of seedling substrate. [0003] Traditional seedling substrates mostly use peat as the main raw material, which accounts for 50-60% of the total substrate, and even needs to be as high as 70-80% to meet the needs of pl...
