Embodiment 1

[0030] Example 1 Exemplary Production Method of Corncob Granular Carbon

[0031] 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.

[0032] Material selection: Naturally air-dry the corncobs of agricultural and sideline products to reduce the water content to below 20%.

[0033] 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.

[0034] Furnace charging and carbonization: put the processed corncob particles int...

Abstract

The invention discloses a carbon-based protection land soil improving agent and application thereof. The carbon-based protection land soil improving agent is characterized by being prepared from biomass particle carbon micro particles, calcium superphosphate, monopotassium phosphate, shell powder, chitosan, compound sodium nitrophenolate, zeolite powder, ferrous sulfate and humic acid. The biomassparticle carbon is one or several kinds of materials from corncob carbon, corn straw carbon, rice hull carbon, peanut shell carbon, mushroom cover carbon and the like. The biomass particle carbon micro particles with the characteristics of rich micropores and strong adsorption performance are used for being compounded with other functional ingredients with the soil conditioning function to prepare the granular carbon-based protection land soil improving agent. The product has the advantages that the preparation process is simple; economic and environment-friendly effects are achieved; the production land soil physicochemical properties can be effectively improved; the soil continuous cropping obstacles can be elimina ted and reduced; the protection land soil production capability is improved; the large-scale population and application in the protection land vegetable production can be facilitated.

Description

technical field [0001] The invention relates to the field of preparation of soil improvers, in particular to a soil improver for carbon-based protected land and its application. Background technique [0002] Protected cultivation can not be restricted by seasonal production, so that plants can avoid the influence of unfavorable natural conditions and grow; it can prolong or advance the growth period and maturity period of plants, and double the yield per unit area. In vegetable production, it cooperates with open field cultivation, storage, processing and other measures, and plays an important role in ensuring the annual balanced supply of vegetables. However, due to the continuous use of protected soil, coupled with the large input of chemical fertilizers and less impact from rainwater leaching, the soil is hindered to varying degrees, which seriously affects the normal growth of vegetables. Therefore, understanding soil changes and carrying out improved management are iss...
