Plant root exudate generation and collection device and collection method thereof

Abstract

The invention provides a plant root secreta generation and collection device and a collection method thereof. The device comprises a plant growth device, a root growth guiding device and a root elution and secreta collection device. The root growth guiding device comprises a net structure and a plastic separator plate. The collection method is a plant root secreta collection method under soil stress under natural conditions and does not interfere root growth and damage a rhizosphere environment. The collection method comprises root secreta effective expression without outside interference after single pathogen infection and monitoring of root secreta change after rhizosphere pathogen infection.

Description

technical field [0001] The invention relates to the technical field of plant protection, in particular to a device for generating and collecting plant root exudates and a collecting method thereof. Background technique [0002] In the process of plant growth and development, the root system, as the contact part of the plant and the soil, not only absorbs water and nutrients from the soil, but also releases some inorganic ions and organic compounds around the root through root secretion, these substances are collectively called root exudates. A large number of studies have shown that root exudates affect soil biological environmental changes and allelopathy, and different crops have different effects on soil microbial communities. Crops play an important role in the soil microbial community through their root exudates. Different crops have different component contents in root exudates, and the same crops have different component contents in root exudates after being infected ...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a device and method for monitoring root exudates changes at any time without disturbing the growth of the root system, without destroying the rhizosphere environment, and at any time after the infection of the rhizosphere pathogens. Susceptible to microbial contamination, sampling is easy to damage the root system, and continuous sampling is not possible. Provide a method for collecting plant root exudates that can be continuously sampled during soil stress under natural conditions.
