Problems solved by technology

[0003] At present, biomass resources are used as soilless cultivation substrates. Most of them are made from agricultural waste such as crop orange stalks, cow dung, mushroom residues, and wood chips, which are fermented at high temperature, decomposed, and harmless. Poor, needs to be resolved urgently

Embodiment 1

[0016] A method for preparing a soilless culture substrate with good fertilizer-retaining effect, comprising the following steps: mixing 50kg of straw powder, 60kg of silkworm excrement, 40kg of sesame meal, and 5kg of microbial content into 1-3×10 6 Each / g of EM bacterial agent was mixed evenly, sealed and fermented for 7 days, and then added 25kg of fermented tea seed meal, 20kg of citric acid residue, 16kg of plant ash, 12kg of peanut shell powder, 18kg of fly ash, 10kg of coal gangue, 20kg of weathered coal, and 8kg of borax Mix evenly, then add 16kg of collagen and mix evenly to obtain a soilless culture substrate with good fertilizer retention effect.

Embodiment 2

[0018] A method for preparing a soilless culture substrate with good fertilizer-retaining effect, comprising the following steps: mixing 70kg of straw powder, 50kg of silkworm excrement, 60kg of sesame meal, and 3kg of microbial content to 1-3×10 6 Each / g of EM bacterial agent is mixed evenly, sealed and fermented for 10 days, then add 15kg of fermented tea seed meal, 30kg of citric acid residue, 8kg of plant ash, 20kg of peanut shell powder, 10kg of fly ash, 20kg of coal gangue, 12kg of weathered coal, and 12kg of borax Mix evenly, then add 10kg of collagen and mix evenly to obtain a soilless culture substrate with good fertilizer retention effect.

Embodiment 3

[0020] A method for preparing a soilless culture substrate with good fertilizer-retaining effect, comprising the following steps: mixing 55kg of straw powder, 58kg of silkworm excrement, 45kg of sesame meal, and 4.5kg of microbial content to 1.5-2.5×10 6 Each / g of EM bacterial agent is mixed evenly, sealed and fermented for 8 days, then add 22kg of fermented tea seed meal, 22kg of citric acid residue, 14kg of plant ash, 14kg of peanut shell powder, 16kg of fly ash, 12kg of coal gangue, 18kg of weathered coal, and 9kg of borax Mix evenly, then add 14kg of collagen and mix evenly to obtain a soilless culture substrate with good fertilizer retention effect.

Abstract

The invention discloses a preparation method of a soilless culture substrate with a great fertilizer maintenance effect. The method includes the following steps of evenly blending straw powder, silkworm excrement, sesame seed meal and EM microbial inoculums, sealing the mixture above for fermentation, then adding fermented tea seed meal, citric acid residues, plant ash, peanut shell powder, pulverized coal ash, coal gangue, weathered coal and borax for even blending, and finally adding collagen for even blending to obtain the soilless culture substrate with the great fertilizer maintenance effect. The obtained soilless culture substrate is low in cost, high in the content of organic substances, abundant in nutrient materials, great in water and fertilizer maintenance effect and suitable for the growth of vegetables, the nutrient materials are not easily lost, since organic agricultural waste is fermented by beneficial microorganisms, the organic agricultural waste is effectively and circularly utilized, the waste is turned into treasure, all the raw materials can be naturally degraded, and the environment is not polluted.

Description

technical field [0001] The invention relates to the technical field of soilless cultivation substrates, in particular to a method for preparing soilless cultivation substrates with good fertilizer retention effect. Background technique [0002] Agricultural environmental pollution and ecological deterioration have become important factors that hinder the sustainable development of agriculture and affect human health. Soilless cultivation is an advanced technology widely used in facility agriculture in the world. Now it has become a reliable way to develop pollution-free green vegetable production. With the With the rise of vegetable soilless cultivation in the whole country, the research on vegetable cultivation substrate has also been paid more and more attention. The quality of the cultivation medium directly affects the growth and development of vegetables. [0003] At present, biomass resources are used as soilless cultivation substrates. Most of them are made from agri...
