[0030] The setting of open water flooding "root box" system
[0031] A glass distilling bottle 1 with a volume of 2 liters is used as a water supply bottle. The mouth of the water supply bottle and the bottom of the bottle each have an opening, and the two openings are respectively sealed with detachable silicone plugs. The mouth is used for ventilation, and the rubber plug at the bottom of the bottle opens a mouth for drainage. The water supply bottle is suspended above the entire system;
[0032] A glass distillation bottle 2 with a volume of 2 liters is used as a water receiving bottle, which is placed on the ground. The mouth of the water bottle is sealed with a detachable silicone plug. The rubber plug opens two ports for water intake and exhaust respectively. The bottom outlet of the water supply bottle is connected to the water inlet of the water bottle with a siphon tube. There is a water valve 11 to control the water flow speed, thereby forming a hydrodynamic drive s...

Abstract
The utility model relates to a method of measuring the respiration of root system, comprising an open style water drive ''root case'' assembled following the sequence of a water supply bottle, a water receiving bottle, a carbon dioxide filtering device, a root case and a carbon dioxide absorption plant. The under-testing live root system is positioned in the root case in the original position; the water supply bottle transports water to the water receiving bottle to form hydrodynamic force drive; the gas in the water receiving bottle is compressed into the root box by the carbon dioxide filtering device; the gas mixed with the root system respiration is taken into the lye of the carbon dioxide absorption plant to be absorbed by the lye and then the discharge of carbon dioxide caused by the respiration of root system and absorbed by the lye in the carbon dioxide absorption plant is analyzed and measured. The utility model has the advantages of making use of hydroenergy skillfully, measuring the respiration of rhizosphere in the original position, enabling to reduce the error in traditional root removing method and being a biologic environment-friendly method of measuring the respiration of rhizosphere.
Description
technical field [0001] The invention relates to a method for measuring root respiration by using an open water flooding "root box" system. Background technique [0002] At present, the methods for measuring rhizosphere respiration mainly include root-cutting method, isolated root method, isotope method and "electric drive root box method". However, the former two have great interference to the soil and the normal breathing environment, and the error is large; the isotope method is also radioactive, not easy to operate, and the cost is high; higher. Contents of the invention [0003] The purpose of the present invention is to propose a low-cost, simple and easy method for measuring root respiration in situ. [0004] The method for measuring root respiration in situ proposed by the present invention includes setting an open water flooding "root box" system, which system includes: [0005] A water supply bottle, suspended at the high position of the system, the bottom of t...
