Device for sampling secretions from plant roots

Abstract

The invention relates to a device for sampling secretions from plant roots, comprising a planting pot (1), a bracket (2), a collecting pipe (3), a water tank (4), a switch I (5), a switch II (6) and a sampling bottle (8), wherein the bracket (2) is in the shape of a root and is arranged in the planting pot (1); the collecting pipe (3) is fixedly connected to the bracket (2); an uncovered head face of the collecting pipe (3) is arranged in the planting pot (1) and the other uncovered head face forms a total outlet end to be arranged at the outer end of the bottom of the planting pot (1); an outlet end of the collecting pipe (3) is arranged in the sampling bottle (8) after connected with the switch II (6); the outlet end of the collecting pipe (3) is connected with the water tank (4) after connected with the switch I (5); and the height of the water level of the water tank (4) is equal to that of the plant roots of the planting pot (1). Therefore, the sampling is easier.

Description

1. Technical field [0001] The invention relates to a sampling device for plant root exudates, in particular to a sampling device for plant root exudates with little plant root exudates. 2. Background technology [0002] Sampling plays a very important role in determining the condition of the whole object, so when analyzing the whole substance, sampling is a very important step; especially during the growth period of plants, through the analysis of plant root exudates, the It is of great significance to study the growth characteristics of plants and to develop fertilizers suitable for plant growth. However, the existing sampling devices for plant root exudates, because the roots of plants are directly grown in the planting pots, most of the plant root exudates Absorbed by the fertilizer, only a small amount of root exudates are collected by the collection tube, and sampling is not easy. 3. Contents of the invention [0003] In order to overcome the above-mentioned technica...
