Embodiment 1

[0040] Embodiment 1 Exemplary production method of corncob granular carbon

[0041] This example exemplarily describes the method of producing corn cob granular carbon using the semi-closed granular carbonization furnace described in the Chinese invention patent No. ZL200710086505.4, including material selection, material processing, furnace charging carbonization, cooling out of the furnace, Steps such as metering and packing, but not limited thereto.

[0042] Material selection: Naturally air-dry the corncobs of agricultural by-products to reduce the water content to below 20%.

[0043] 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.

[0044]Furnace charging and carbonization: put the processed corncob particles into the fu...

Embodiment 2

[0048] Embodiment 2 peanut shell granular carbon production method

[0049] This example exemplarily describes the method of producing peanut shell granular charcoal using the semi-closed granular carbonization furnace described in the Chinese invention patent No. ZL200710086505.4, including material selection, furnace charging carbonization, cooling out of the furnace, metering and packaging, etc. steps, but not limited to this.

[0050] Material selection: Naturally air-dry the peanut shells of agricultural and sideline products to reduce the water content to less than 20%.

[0051] Furnace charging and carbonization: Put the cleaned peanut shells into the furnace body, and the initial amount of material added should cover the burner by 10-25 cm. Ignite the igniter in the ignition plate of the burner. Described igniter is diesel oil. After the material is ignited, it continues to ignite spontaneously without an external heat source. The material is anoxic and carbonized ...

Embodiment 3

[0055] Embodiment 3: carbon-based soil conditioner production process

[0056] (1) Mix quicklime, 80-mesh biomass granular charcoal and binder in proportions of 5%, 85% and 10%, and stir evenly with a ZLC-300 mixer.

[0057] (2) Carry out pressure granulation with (1) with disc granulator, make the charcoal-based soil conditioner that contains granular charcoal 85%.

[0058] (3) Measurement and packaging.

[0059] The binder is clay.

Abstract

The invention relates to the crop growing field, particularly relates to a soil improver taking biomass particle carbide discarded in agriculture and forestry as a matrix and a preparation method thereof. The carbon-base soil improver comprises biomass particle charcoal, calcium magnesium phosphate or calcined lime, and binder, and also comprises other fertilizers, such as urea, monoammonium phosphate powder, potassium chloride, zinc sulfate, boricfertilizer, manganese sulfate, ammonium molybdate, ferrous sulfate and copper sulfate and the like. The biomass particle charcoal is a black powdered carbon particle (carbon soot) generated by incomplete combustion of the biomass under hypoxemia condition, has various properties similar with soil humus (acid) and strong ability to absorb and maintain nutrients, such as nitrogen, phosphorus and potassium and the like, and has obvious water retention and moisture preservation effects. The soil improver prepared by the preparation method has the characteristics of soil structure improvement, moisture and fertility preservation, temperature increasing, efficient environmental protection and wide application prospects and the like.

Description

technical field [0001] The invention relates to the field of crop cultivation, in particular to a soil conditioner using agricultural and forestry waste biomass granular charcoal as a matrix and a preparation method thereof. Background technique [0002] Land is the most important means of agricultural production. Since the reform and opening up, the steady improvement of agricultural production capacity has provided strong support for the rapid development of my country's economy, but at the same time it has overdrawn the potential of land production to a certain extent. On the one hand, the long-term and extensive use of chemical fertilizers has caused a series of problems such as reduced fertilizer efficiency, soil compaction, and water pollution; on the other hand, high-intensity agricultural production and land use have led to increasingly serious problems such as soil acidification and desertification, which have become constraints The bottleneck of my country's agricu...
