Embodiment 1

[0021] Embodiment 1: corn cob charcoal production method

[0022] Exemplarily, the method for producing corncob granular carbon using the simple corncob granular carbonization furnace described in the Chinese invention patent No. ZL200710086505.4 includes steps such as material selection, material processing, furnace charging, carbonization, cooling and discharging, and metering and packaging. , but not limited to this.

[0023] Material selection: Naturally air-dry the corncobs of agricultural by-products to reduce the water content to below 20%.

[0024] Material processing: use any crushing method in the prior art to process and crush the above-mentioned qualified corncobs, and the diameter of the crushed corncobs is 2-10mm. The crushed corn cob particles can be sieved, and the corn cob particles that do not meet the requirements can be reprocessed.

[0025] Furnace charging and carbonization: put the processed corncob particles into the furnace body, and the initial amou...

Embodiment 2

[0030] Embodiment 2: Carbon-based paddy rice seedling raising substrate formula production process

[0031] Follow the steps below to mix by weight ratio or weight percentage:

[0032] (1) Stir the biochar particles and peat evenly with a ZLC-300 mixer at a ratio of 10:7.

[0033] (2) Use wood vinegar to adjust the acidity to pH 4.5-5.5, and the dosage is about 0.15ml / g according to the weight percentage.

[0034] (3) Measurement and packaging.

Embodiment 3

[0035] Embodiment 3: Carbon-based paddy rice seedling raising substrate formulation production process

[0036] Follow the steps below to mix by weight ratio or weight percentage:

[0037] (1) Mix biochar particles, peat, and perlite in a ratio of 2:2:1.

[0038] (2) Mix (1) with diammonium phosphate, potassium dihydrogen phosphate, and zinc sulfate at a ratio of 95%, 3%, 1.5%, and 0.5%, and stir evenly with a ZLC-300 mixer.

[0039] (3) Use wood vinegar to adjust the acidity to pH 4.5-5.5, and the dosage is about 0.13ml / g according to the weight percentage.

[0040] (4) Measurement and packaging.

Abstract

The invention relates to a charcoal-based rice seedling substrate and a preparation method thereof. The charcoal-based rice seedling substrate contains biomass, namely, grain charcoal, grass charcoal and wood vinegar, and can further comprise perlite and other fertilizers such as diammonium phosphate, potassium sulfate, zinc sulfate and monopotassium phosphate. The charcoal-based rice seedling substrate can be widely applied to rice seedling cultivation.

Description

technical field [0001] The invention relates to a carbon-based rice seedling raising substrate and a preparation method thereof. Background technique [0002] Seedling raising is an important part of high-yield rice cultivation. In production, farmers often take soil from dry fields and make seedbeds after disinfection and acid adjustment. With the continuous improvement of rice cultivation technology and the promotion of industrialized centralized seedling raising methods, the disadvantages of traditional seedling raising methods have become increasingly prominent. First, taking soil leads to the destruction of the structure of the plow layer, and the concentrated industrial seedlings are faced with the embarrassing situation of no soil available. Second, even if soil is available, the preparation, disinfection, and acid adjustment procedures of bed soil are relatively complicated, and pesticide residues and phytotoxicity are prone to occur. Its three, the bed soil capac...
