Embodiment Construction

[0028] Embodiments of the present invention: it comprises the following steps,

[0029] Step 1, select the plant that grows simultaneously under the reference environment and the environment under investigation, and known bicarbonate ion utilization share under the reference environment as the measurement object, where the known bicarbonate ion utilization share under the reference environment Plants refer to plants that have been studied more, have carbon dioxide response curves that are easy to make, and have obtained bicarbonate ion utilization ratios through isotope techniques;

[0030] Step 2, utilize the portable photosynthetic instrument to measure the carbon dioxide response curve of the photosynthesis of the plant leaves growing under the reference environment and the investigated environment respectively by conventional methods; the carbon dioxide response curves of the photosynthesis of the plant leaves here are conventional methods During the time period from 9:00 ...

Abstract

The invention discloses a method for rapidly obtaining a supplementing and recycling quota of plant inorganic carbon and belongs to the field of a crop information detection technology, afforestationand ecological environment management. The method comprises the following steps: determining a carbon dioxide response curve of photosynthesis of plant leaves by utilizing a portable photosynthetic apparatus; obtaining a relation equation between a net photosynthetic rate and extracellular atmospheric carbon dioxide concentration, and a relation equation between the net photosynthetic rate and intercellular carbon dioxide concentration; deriving the equations to obtain carboxylation efficiency of the plant leaves with the extracellular atmospheric carbon dioxide concentration of 100mu mol*mol<-1> on the extracellular atmospheric carbon dioxide and the intercellular atmospheric carbon dioxide, so as to obtain a direct utilization quota of atmospheric carbon dioxide of plants and the supplementing and recycling quota of the plant inorganic carbon. Meanwhile, the quota of recycled organic carbon of the plants can be obtained by directly utilizing a known bicarbonate ion utilization quotaand a plant atmospheric carbon dioxide direction utilization quota; or the bicarbonate ion utilization quota of the plants is obtained according to a known plant organic carbon recycling quota.

Description

technical field [0001] The invention relates to the fields of crop information detection technology, afforestation and ecological environment management, in particular to a method for quickly obtaining the share of plant inorganic carbon replenishment and reuse, which can quickly obtain plant bicarbonate ion utilization and organic carbon reuse information , to provide a scientific basis for the screening of suitable plants in karst. Background technique [0002] When plants encounter karst stress (karst drought, pH, bicarbonate ions, and low inorganic nutrients, etc.), the carboxylation of plants is reduced due to the reduction of stomatal conductance, the regeneration of RuBP, phosphorus, and the delay in the output of photosynthetic products. efficiency, thereby greatly reducing the net photosynthetic rate. Plants can solve these problems from two aspects: one is to increase the activity of carbonic anhydrase to convert HCO in cells 3 - into water and CO 2 , to direct...
