A device for dynamically measuring carbon loss in plant root respiration

Abstract

The invention discloses a device for dynamically measuring the respiration carbon loss of plant roots, which comprises an airtight container composed of an upper top, a lower bottom and a middle container wall, and is characterized in that the upper top has an air intake pipe, An exhaust pipe, a rubber stopper that seals the plant and the container, and a feed piston for adding reagents to the container; the exhaust pipe communicates with the sampling bottle and the gas storage tank through a conduit, and three tubes are installed on the conduit. through valve; the lower bottom communicates with the liquid storage tank through a conduit with a switch. The device for dynamically measuring the respiration carbon loss of plant roots in the present invention can not only accurately measure the respiration rate or root vitality of the roots, but also has the advantages of simple structure, convenient use, low production cost and easy popularization and application.

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.
