Embodiment 1

[0016] (1) Fermentation treatment steps of paper industry waste sawdust: Add 2kg of urea to each cubic meter of paper industry waste sawdust after sieving, add superphosphate to adjust pH to 8, add 0.25wt% of Bacillus subtilis , and adjust the moisture to a moisture content of 70wt%. After mixing evenly, turn over and ferment regularly. After the temperature rises to 60°C, keep it for 7 days, and cool it down in the air for later use.

[0017] (2) The composting treatment of papermaking sludge includes the following steps: firstly treat the papermaking sludge to a moisture content of 55wt%, and then undergo a static pile-type aerobic composting treatment under ventilated conditions, dry it in the air, and crush it for later use.

[0018] (3) Mix the waste sawdust, perlite, and sand from the papermaking industry after fermentation treatment obtained in step (1) and the composted papermaking sludge obtained in step (2) at a ratio of 2:2:1:5 to obtain a cultivation substrate 1. ...

Embodiment 2

[0020] (1) Fermentation treatment steps of paper industry waste sawdust: Add 1.5kg of urea to each cubic meter of paper industry waste sawdust after sieving, add superphosphate to adjust pH to 7, add 0.2wt% subtilis spores Bacillus, and adjust the moisture to a moisture content of 60wt%. After mixing evenly, turn over and ferment regularly. After the temperature rises to 60°C, keep it for 7 days, and then cool it down in the sun for later use.

[0021] (2) The composting treatment of papermaking sludge includes the following steps: firstly treat the papermaking sludge to a moisture content of 50wt%, and then undergo a static pile-type aerobic composting treatment under ventilated conditions, dry it in the air, and crush it for later use.

[0022] (3) Mix the waste sawdust, perlite, and sand from the papermaking industry after fermentation treatment obtained in step (1) and the composted papermaking sludge obtained in step (2) at a ratio of 3:3:2:6 to obtain a cultivation substr...

Embodiment 3

[0024] (1) Fermentation treatment steps of paper industry waste sawdust: Add 1.5kg of urea to each cubic meter of paper industry waste sawdust after sieving, add superphosphate to adjust pH to 7, add 0.15wt% subtilis spores Bacillus, and adjust the moisture to a moisture content of 55wt%. After mixing evenly, turn over and ferment regularly. After the temperature rises to 60°C, keep it for 6 days, and cool it down in the sun for later use.

[0025] (2) The composting treatment of papermaking sludge includes the following steps: first, the papermaking sludge is treated to a moisture content of 45wt%, and then it is subjected to static pile-type aerobic composting under ventilated conditions, air-dried, crushed and then used for later use.

[0026] (3) Mix the fermented waste sawdust, perlite, and sand from the papermaking industry obtained in step (1) and the composted papermaking sludge obtained in step (2) at a ratio of 2.5:2.5:1:5.5 to obtain a cultivation substrate 2.

Abstract

The invention discloses a culture medium which is used for cultivating flowers and plants and comprises waste saw dust of paper manufacturing industry, perlite, sand, and paper mill sludge, wherein the waste saw dust, the perlite and the sand are subjected to fermentation treatment; the paper mill sludge is subjected to compost treatment; the volume ratio of the waste saw dust, the perlite, the sand and the paper mill sludge is (1-3):(1-3):(0.5-2):(4-6). According to the invention, solid wastes of the paper manufacturing industry are taken as raw materials to prepare the culture medium, so that resource utilization of the solid wastes of the paper manufacturing industry is realized, the environmental problem of secondary pollution caused by the solid wastes is solved; in addition, the culture medium is excellent in physical and chemical properties, rich and comprehensive in nutrient elements; moreover, the nutrition in the culture medium can be continuously degraded and released for growth and development of crops, so the culture medium can be widely applied to the soilless culture technology of vegetables, flowers and plants.

Description

technical field [0001] The invention relates to the field of plant cultivation substrates, in particular to a cultivation substrate made from papermaking waste, and also relates to a preparation method of the cultivation substrate. Background technique [0002] At present, soilless cultivation is mostly used in flower cultivation at home and abroad, and peat is usually selected as the main component of the substrate for soilless cultivation, and at the same time it is mixed with other 2-3 substrates for use. The physical and chemical properties of the mixed substrate are obviously better than that of a single substrate. Conducive to the growth of flowers. [0003] Peat, also known as peat, is a product of the development of swamps. It was formed in the Quaternary Period. It is a natural organic matrix formed by the continuous accumulation and transformation of the residues of swamp plants under the watery and aerobic conditions. Peat contains a lot of water and not complete...
