A method for obtaining the utilization share of plant bicarbonate in wild habitat

Abstract

The invention discloses a method for acquiring bicarbonate using share of plants in field habitat, and belongs to the field of crop information detection technologies and ecological environmental management. The method includes acquiring extracellular atmospheric carbon dioxide concentration and intercellular carbon dioxide concentration data by the aid of portable photosynthetic apparatuses, measuring air carbon dioxide and soil bicarbonate using stable carbon isotope fractionation values of the plants at different seedling ages and different growth periods in different environments, and combining atmospheric carbon dioxide stable carbon isotope composition and rhizosphere soil bicarbonate stable carbon isotope composition of the plants with each other; acquiring instant information of the bicarbonate using share of the plants at the different seedling ages and the different growth periods in the different environments according to double-end-member isotope hybrid models. The method has the advantages that atmospheric carbon dioxide using share of the plants at the different seedling ages and the different growth periods in the field habitat can be quickly, conveniently and accurately acquired in real time by the aid of the method, and the bicarbonate using share of the plants in the field habitat also can be acquired by the aid of the method.

Description

technical field [0001] The present invention relates to the fields of crop information detection technology and ecological environment management, and in particular to a method for obtaining plant bicarbonate utilization shares in wild habitats, which can measure in real time different seedling ages and different growth stages without cumbersome cultivation of plants. Plant utilization information of bicarbonate provides a scientific basis for the screening of suitable plants in karst. Background technique [0002] In recent years, many experiments have proved that plants can not only use carbon dioxide in the atmosphere as a substrate for photosynthesis, but also use bicarbonate from soil for photosynthesis. Especially in karst limestone areas with high concentrations of bicarbonate, the use of photosynthesis based on the measurement of atmospheric carbon dioxide flux to measure the inorganic carbon assimilation capacity of plants seriously underestimates the productivity o...
