preparation example Construction

[0037] Such as figure 1 Shown, the present invention proposes a kind of rice seedling raising matrix preparation method, comprises the steps:

[0038] Ferment the raw material, and separate the solid and liquid from the fermented material; in the present invention, it is preferred to subject cow dung to anaerobic fermentation, and separate the solid and liquid from the fermented material to separate the solid and liquid; specifically The cow dung is subjected to anaerobic fermentation for 30-40 days, and the fermented material is subjected to solid-liquid separation twice to separate biogas residue and biogas slurry; manure is fermented;

[0039] The solid after solid-liquid separation is treated to reduce the water content of the solid; in the present invention, the biogas residue after solid-liquid separation is preferably treated to reduce the water content of the biogas residue to 40%-50%. Specifically, the biogas residue after solid-liquid separation is processed to red...

Embodiment 1

[0044] Anaerobic fermentation of fresh cow dung for 30 days, and solid-liquid separation of the fermented material twice to separate biogas residue and biogas slurry;

[0045] Treat the biogas residue after solid-liquid separation to reduce the water content of the biogas residue to 40%, and take 400 parts for use;

[0046] After mixing peat soil and vermiculite in the ratio of 2:1 for drying and crushing and sieving, 476 parts are mixed with the treated solid to form a mixture, and carry out secondary fermentation for 15 days;

[0047] Add 11 parts of organic-inorganic compound fertilizer, 1 part of silicon dioxide, 0.5 part of copper sulfate and 1 part of Bacillus subtilis to the mixture after secondary fermentation;

[0048] Add 10.5 parts of furfural to the mixture after the secondary fermentation of the mixed components to carry out acid adjustment treatment; and then form the required matrix.

Embodiment 2

[0050] The fresh cow dung is subjected to anaerobic fermentation for 32 days, and the fermented material is subjected to solid-liquid separation twice to separate biogas residue and biogas slurry;

[0051] Treat the biogas residue after solid-liquid separation to reduce the water content of the biogas residue to 45%, and take 430 parts for use;

[0052] After mixing peat soil and vermiculite in a ratio of 2.3:1, air-dried, crushed and sieved, 500 parts were mixed with the treated solid to form a mixture, and secondary fermentation was carried out for 15 days;

[0053] Add 11 parts of organic-inorganic compound fertilizer, 1 part of silicon dioxide, 0.5 part of copper sulfate and 1 part of Bacillus subtilis to the mixture after secondary fermentation;

[0054] Add 10.5 parts of furfural to the mixture after the secondary fermentation of the mixed components to carry out acid adjustment treatment; and then form the required matrix.

Abstract

The invention provides a preparation method of rice seedling raising substrate, and solves the resource consumption problem caused in substrate preparation in the prior art. The preparation method of the rice seedling raising substrate includes: S1, fermenting raw material, and performing solid-liquid separation on the fermented material; S2, processing solid obtained after the solid-liquid separation in step S1 so as to reduce water content in the solid; S3, after mixing turfy soil and vermiculite, after being processed, mixing the turfy soil and vermiculite with the solid after being processed in step S2, and carrying out secondary fermentation on a formed mixture; S4, adding mixing components in the mixture after the secondary fermentation; S5, adding reactant in the mixture after being added with the mixing components for acid modulation treatment. The substrate prepared through the preparation method of the rice seedling raising substrate can replace turf for raising seedlings, and then resource consumption is avoided.

Description

technical field [0001] The invention relates to the field of substrates, in particular to a method for preparing rice seedling raising substrates. Background technique [0002] In recent years, the number of rice transplanters has increased rapidly, and the quality requirements for machine-transplanted seedlings have been increasing. The market for plate-raised seedlings has grown rapidly, and the substrate for rice seedlings has gradually become a research hotspot. In the selection of substrate raw materials, in addition to soil, carbonized chaff and fungus residue, crushed straw, bagasse, fly ash, peat, sawdust, coconut shell, biogas residue, water hyacinth, vermiculite, perlite, organic fertilizer Seedling raising substrate of various raw materials; [0003] With the application of the substrate, the physical and chemical properties of the substrate have been gradually improved, especially the improvement of the water and fertilizer retention performance, which has solve...
