Abstract

The invention provides a mineral source carbocoal charcoal soil conditioner which is prepared from oil shale carbocoal charcoal and auxiliary materials. The oil shale carbocoal charcoal is prepared from oil shale through thermal treatment. The mineral source carbocoal charcoal soil conditioner can condition and repair different kinds of acid soil, gradually improve the soil fertility, improve the crop quality and yield, and achieve the purposes of environmental protection and ecology; in addition, the source of the oil shale is quite wide. The mineral source carbocoal charcoal soil conditioner heats mineral substance or biomass on the oxygen-free condition for pyrolysis, and the oil shale carbocoal charcoal is produced after relevant volatile matter is extracted; according to the oil shale carbocoal charcoal, after the raw material oil shale is subjected to thermal treatment, all bacteria and viruses are killed at the high temperature, and meanwhile the sterilization and disinfection effect on soil is achieved. The preparation method is simple, and the processing cost is low.

Description

technical field [0001] The invention belongs to the technical field of soil improvement and adjustment, and in particular relates to a mineral source semi-coke biochar soil conditioner. Background technique [0002] Cultivated land is the foundation of agricultural production. With the evolution from agricultural society to industrial society, modern industry has brought many new problems while bringing great development to agriculture. Fertilizer pollution, pesticide pollution, plastic pollution, straw pollution, livestock manure pollution, and heavy metal pollution have become major issues that seriously threaten the safety of people's lives and property and the healthy development of the national economy. [0003] At present, the use of soil conditioners to solve soil pollution problems is relatively fast and low in cost, but the biggest problem at present is that the raw materials for the production of soil conditioners are limited, and there are very few enterprises wi...
