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
The present invention relates to a kind of device of dynamically detecting carbon element loss of root system of plant.
Background technology
Root system has important regulation to plant growth and development process, and its Physiological and Biochemical Metabolism process is the weak field of subject researchs such as agronomy, ecology.Plant growth and development process is subjected to Different Organs to breathe the influence of carbon element loss, and root system is an important carbon element storehouse, and its respiration is one of feedback approach important in the ecosystem Carbon cycle.Because a lot of researchs stress the research of aerial part, also very limited with regard to environmental factor to the understanding of underground carbon element storehouse regulation and control, root system carbon element amount almost accounts for 50% of the total carbon element amount of plant, but, breathe at present the research method of carbon element loss, and influence the assimilation products accumulation and the mechanism of distributing is still waiting to study with regard to root system of plant.Many in the past with hydroponics, air culture with separate respiratory rate or the root system vigor that root system is measured root system, the actual physiological situation of root system differs greatly under these measurement results and the state of nature, is difficult to definitely grasp plant carbon element balance and distribution.
Summary of the invention
With not enough, the object of the present invention is to provide a kind of device of dynamically detecting carbon element loss of root system of plant at above-mentioned problems of the prior art, this device can be measured the respiratory rate or the root system vigor of root system accurately.
The technical scheme that realizes the foregoing invention purpose is a kind of device of dynamically detecting carbon element loss of root system of plant, comprise one by last top, go to the bottom and closed container that middle chamber wall is formed, it is characterized in that, push up a draft tube, a gas outlet, a rubber stopper and a charging piston that is used in container, adding reagent that makes plant and seal of vessel on described; Described gas outlet is communicated with sampling jar and gas-holder respectively by conduit, and three-way pipe is installed on the conduit; Described going to the bottom is communicated with fluid reservoir by the conduit that has switch.
Described gas-holder also is connected with a wireway.
Also be connected with a mozzle on the described fluid reservoir.
The device principle of work of dynamically detecting carbon element loss of root system of plant of the present invention:
The present invention is oxygen and the synthetic carbohydrates reaction of photosynthesis that absorbs according to the plant tissue utilization, discharges CO
2And the physiological metabolism process of energy (ATP, NADPH etc.), the O of the plant tissue by measuring certain volume or weight
2Content or CO
2The change of content can be calculated the respiration intensity of plant tissue.
Concrete using method is: (leave the space of suitable air feed circulation in the container) in the container of earlier soil being packed into, with plant by going into the soil from rubber stopper mouth kind, and with rubber stopper with good seal between plant and the container, open draft tube, outside air is entered in the container, the charging piston can be opened as required, in container, add reagent, when the gas volume in the container just passes through gas outlet automatically after to a certain degree, conduit, T-valve enter in the gas-holder with jar in reagent reacting, when needing sampling, open T-valve gas is flowed into sampling jar, will measure by exact instrument again behind the sample; When the reagent in the container is too much, opens supravasal switch waste liquid is flowed into fluid reservoir.
The device of dynamically detecting carbon element loss of root system of plant of the present invention not only can measure the respiratory rate of root system or root system vigor accurately but also simple in structure, easy to use, production cost is low easy to utilize.
