Problems solved by technology

However, the substances obtained by this method contain complex compounds that are originally present in the soil. In addition, the root system leaching method is that the root system will be damaged during the leaching process after the root system is dug out, resulting in the collection of root exudates containing The substances in the root system and the wound fluid may have a greater impact on the experimental results

Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings, but the present invention is not limited to the following embodiments.

[0029] like figure 1 As shown, it is a schematic structural diagram of the device for collecting plant root exudates of the present invention, which includes a root box 1, and two opposite root exudate collection tanks 2 are arranged in the root box 1. ,like figure 2 Shown, root exudation collection tank 2 is hexagonal shape, and its top is provided with opening, and root system secretion collection tank 2 is surrounded by PVC board). The middle part of the wider vertical side wall of the root exudate collection tank 2 is provided with a through hole, and the through hole is sealed by a nylon mesh 3, and the average pore diameter of the nylon mesh 3 is 48 μm.

[0030] When adopting the device of the present invention to collect root exudates, it can be carried out according to the following steps...

Abstract

The invention discloses a root exudate collecting device and method for gramineous plant. The device comprises a root box; two oppositely arranged root exudate collecting tanks arranged in the root box, wherein the top of each root exudate collecting tank is provided with an opening, and through holes are formed in four vertical side walls, which are arranged in parallel, of the two root exudate collecting tanks, and are sealed by grids. The invention provides a plant root exudate collecting method. The method comprises the following steps: placing soil in the root box and the root exudate collecting grooves in the plant root exudate collecting devices; growing plants between the two root exudate collecting grooves, wherein the roots of the plants grow, a part of the roots enter the root exudate collecting grooves through the grids and the openings in the tops of the root exudate collecting grooves, and then the root exudate of the plants can be collected from soil in the root exudatecollecting grooves. According to the method, the roots of plants do not need to be damaged when root exudates are collected, and the reliability of experiments is improved.

Description

technical field [0001] The invention relates to a collection device and method for gramineous plant root exudates, belonging to the field of soil and plant science and technology. Background technique [0002] Root exudate is the general term for all substances secreted by the root system to the culture medium in an active or passive manner during the growth of plants, including organic / inorganic ions, plant hormones, root cell sheds and their decomposition products, etc., the synthesis of root exudates The process of exudation and secretion is an important way to realize the interaction between plants and the rhizosphere environment. It can not only improve the properties of the rhizosphere soil, regulate the composition of the rhizosphere microbial community, but also allow plants to feel the changes of root exudates and their rhizosphere microecology, feedback Regulates plant growth. [0003] There is no uniform standard for the collection method of root exudates, and mo...
