Problems solved by technology

[0004] The organic carbon in the soil mainly comes from plant residues, so its composition is similar to that of biochar. When biochar is applied to the soil, it is difficult to distinguish the two by conventional means.

Abstract

The invention discloses a preparation method of a marked plant and a preparation method of marked biochar. The preparation method of the marked plant comprises the following steps: preparing a box body; placing a plant in the box body, wherein the plant has photosynthesis capability; preparing a marking gas in the box body, wherein the marking gas is an isotope-marked carbon dioxide gas; and standing the plant for a preset time to make the plant absorb the marking gas in order to form the marked plant. The carbon element in the plant is marked in the growth process of the plant, the concentration of <13>CO2 in the box body can be controlled by controlling the concentration of Na213CO3, <13>CO2 is prepared through a chemical technology, and the utilization rate of <13>C is increased.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a method for preparing labeled plants and a method for preparing labeled biochar. Background technique [0002] At present, my country's soil pollution is becoming more and more serious, the degree of pollution is intensifying, and the polluted area is expanding year by year. Most of the pollutants in the soil have poor mobility and long residence time in the soil. Some pollutants (such as heavy metals) cannot be degraded by microorganisms and will endanger human health through groundwater and plant root absorption. As a green and efficient heavy metal chemically stable material, biochar can not only fix carbon, improve soil fertility, improve acidity and alkalinity, reduce the loss of soil nitrogen, phosphorus and other nutrients, but also adsorb pollutants in the soil , effectively reducing the mobility of pollutants in the soil, is a cost-effective soil remediation agent.
