Abstract

The invention discloses a preparation containing plant extracts for soil remediation and drought resisting. The plant extracts contain biomass carbon and a biomass extract, and the weight ratio between biomass carbon and the biomass extract is 1:2-3; biomass raw materials are treated by a raw material layer, a pyrolysis layer, an oxidizing layer, a reducing layer and a cooling layer in a condition of a gasifying agent, and the biomass carbon and the biomass extract are obtained. The preparation is advantageous in that the problems of easy hardening of soil due to small apertures, bad soil structure, large retention evaporation capacity, soil acidifying, fertility decrease, low nutrients and low fertility keeping, and the like, effects of soil modification and drought resistance are realized, the effects are taken rapidly, the cost is low and the effects are lasting.

Description

technical field

[0001] The invention relates to a plant extract, in particular to a preparation containing the plant extract capable of soil restoration and drought resistance, and belongs to the field of plant extracts. Background technique

[0002] Biomass pyrolysis gasification is the thermal decomposition of biomass raw materials (mainly agricultural and forestry plants, such as branches, straw, rice husk, etc.) under high temperature and limited oxygen conditions, and gasification to produce combustible gas, biomass carbon and biomass The process of substance extraction. The main components of biomass raw materials are cellulose (a linear high-molecular compound homogeneous high polysaccharide connected by β-D-glucose through 1-4 glycosidic bonds), hemicellulose (a non-cellulose high polysaccharide in the cell wall , composed of two or more sugar groups, with side chains or branched heterogeneous high polysaccharides), lignin (which is formed by connecting phenylacryli...

Embodiment 1

[0017] A preparation containing plant extracts capable of soil restoration and drought resistance, the plant extracts being biomass carbon and biomass extract, the weight ratio of the biomass carbon and biomass extract being 1:2-3; The preparation process of described biomass carbon and biomass extract is as follows:

[0018] Under the condition of gasification agent, the biomass raw material passes through raw material layer, pyrolysis layer, oxidation layer, reduction layer and cooling layer to obtain gas-liquid mixture and biochar. Among them, the temperature in the pyrolysis zone is 200-600°C, and the raw materials will produce a large amount of combustible gas (CO, H 2 , CH 4 etc.), charcoal and biomass extract; the temperature in the oxidation zone is 600-800°C, and the biochar reacts with gasification agent C+O 2 =CO 2 ,2C+O 2 =2CO; the temperature in the reduction zone is 800-600°C, the reduction reaction, C+H 2 O=CO+H 2 ,CO+H 2 O=CO 2 +H 2 , C+CO 2 =2CO,C+2H...
