Abstract

The invention relates to an in-situ measurement device for measuring plant root respiration. The device consists of a soil carbon flux measurement system, a root box, a pipeline system and fine sand, wherein the soil carbon flux measurement system is connected with the root box through a gas sampling inlet hose and a gas sampling outlet hose; the fine sand is filled in one third part from the bottom in the root box; a root implantation hole, a gas inlet tube hole, a moisture complement tube hole and a gas sampling inlet hose hole are formed from bottom to top in the side wall, close to the bottom, of the root box; the pipeline system consists of a gas inlet tube, a moisture complement tube, the gas sampling inlet hose, an exhaust tube and the gas sampling outlet hose; and the exhaust device is an electric exhaust pump or a large-capacity work drum. By virtue of the device, a root system can be separately isolated, so that the living activity of the root system is ensured, the precise research on the root respiration and the relationship between the root respiration and soil respiration is facilitated, and the observation is facilitated. The device is simple in structure, low in manufacturing cost and convenient to popularize and use.

Description

technical field [0001] The invention relates to the field of research on respiration of plant roots, in particular to an in-situ measuring device for measuring respiration of plant roots. Background technique [0002] Soil respiration is the release of CO from the soil 2 The process is mainly produced by biological oxidation of organic matter and root respiration, and a very small part is released by soil animals and chemical oxidation. Accurately measuring the data related to root respiration, such as carbon dioxide concentration, humidity, temperature, etc., will greatly promote the study of soil respiration and root metabolism in the soil. [0003] Currently, the soil CO used in this field 2 Flux in-situ measurement methods and devices, such as the invention patent with patent application number 201210231267.2 specifically discloses an in-situ dynamic observation device, system and observation method for plant roots under soil cultivation conditions. The device describ...
