Device for dynamically detecting carbon element loss of root system of plant

Abstract

The invention discloses a device for dynamically detecting the carbon loss during plant root respiration. The device comprises a closed container composed of an upper top, a lower bottom and a middle container wall. The device is characterized in that an air inlet pipe, an air outlet pipe, a rubber stopper for sealing the plant and the container, and a charging piston for adding reagent into the container are arranged at the upper top; the air outlet pipe is respectively communicated with a sample bottle and an air reservoir through guide pipes, and a three-way valve is installed on the guide pipes. The lower bottom is communicated with a liquid reservoir through a guide pipe provided with a switch. The device for dynamically detecting the carbon loss during plant root respiration can be utilized for correct detecting the respiration rate or root activity of the root, the structure is simple, the operation is convenient, the production cost is low, and the popularization and the application are convenient.

Description

technical field [0001] The invention relates to a device for dynamically measuring the respiration carbon loss of plant roots. Background technique [0002] The root system plays an important role in regulating the growth and development of plants, and its physiological and biochemical metabolic processes are weak areas of research in agronomy, ecology and other disciplines. The process of plant growth and development is affected by the loss of respiration carbon in different organs. The root system is an important carbon pool, and its respiration is one of the important feedback pathways in the ecosystem carbon cycle. Since many studies focus on the research on the aboveground part, the understanding of environmental factors on the regulation of underground carbon pools is still very limited. The carbon content of roots accounts for almost 50% of the total carbon content of plants. Research methods, as well as mechanisms affecting assimilation product accumulation and dist...

Problems solved by technology

Since many studies focus on the research on the aboveground part, the understanding of environmental factors on the regulation of underground carbon pools is still very limited. The carbon content of roots accounts for almost 50% of the total carbon content of plants. However, at present, the carbon loss of plant root respiration research methods, and the mechanisms affecting assimilation product accumulation and distribution are yet to be studied

In the past, hydroponic culture, aeroponic culture and root separation were used to measure the respiration rate or root activity of the root system. These measurement results are quite different from the actual physiological conditions of the root system in the natural state, and it is difficult to accurately grasp the carbon balance and distribution of plants.
