Making method for particle substrate

Abstract

The invention discloses a making method for a particle substrate. The making method comprises the following steps: step one, mixing straws, excrement of people and livestock and food industrial leftovers according to the volume ratio of 2:1:1, adding water and preparing a mixed material, wherein the mass of the water in the mixed material is 60%, adding fermentation strains to the mixed material and sending to a fermentation tank after adequately stirring; step two, detecting the material temperature in the fermentation tank, while the material temperature in the fermentation tank is only reduced and is not ascended, finishing the material fermentation, wherein the total mass content of nitrogen phosphorus and potassium in the fermented material is greater than 5.0%, and the carbon nitrogen ratio thereof is less than 30:1; step three, adding 30% of peat by volume ratio to the fermented material, so that the total mass content of the nitrogen phosphorus and potassium is 2%-3%, PH is 6.5-7.5, and conductivity rate EC is less than 2.5 ms/cm; and step four, smashing the prepared material to be 1-3 mm of powder, making 4-10 mm of spherical particles by the powder, and conveying the spherical particles to an enveloping machine, adding xanthan gum, enveloping and drying, finally packaging and storing.

Description

technical field [0001] The invention relates to a method for making a matrix, in particular to a method for making a granular matrix. [0002] technical background [0003] Seedling-raising substrate is a formulated material with organic and inorganic substances as raw materials, which has stable physical and chemical properties after treatment and can meet the growth needs of vegetable seedlings. The seedling-raising substrate is generally a powdery substance with a water content within 40% mixed in a certain proportion by peat, perlite, vermiculite, fully fermented organic matter, and inorganic salts, and its pH is 5.5-7.5 (acid-base of the substrate) properties), EC is below 1.5ms / cm (conductivity of matrix). Among them, perlite plays the role of ventilation and increasing porosity, and vermiculite plays the role of water retention. However, the existing powdery seedling-raising substrate is inconvenient to use, and its nutrient content is generally below 2%, and the fer...

Problems solved by technology

[0005] The purpose of the present invention is to solve the problems that the existing powdered seedling-raising substrates have low fertilizer content, need to add fertilizer during the seedling age, have poor water permeability, and the emergence rate and later root growth are easily affected.
