Embodiment Construction

[0027] The present invention will be described in further detail below in conjunction with the examples, but the embodiments of the present invention are not limited thereto.

[0028] A collection device for soil plant root exudates, including a growth box and a collection box. The side of the growth box is a right-angled triangular plate, and a slot 5 parallel to the hypotenuse is provided on the right-angled triangular plate, and an inclined plexiglass insert plate 2 is fixed through the slot between the two triangular plates. An organic perforated glass plate 7 is arranged between the growth box and the collection box, and a polytetrafluoroethylene film 4 is pasted on the organic perforated glass plate 7. Two rows of small holes 20 are respectively arranged on the upper and lower sides of the organic perforated glass plate 7, and the upper and lower rows of holes 20 are arranged on the organic perforated glass plate. Aperture corresponds to the upper collection box 10, and ...

Abstract

This invention discloses one earth plant stem secretion collection method and device, wherein, the collection device comprises growth case and collection case with one block coated with film hole glass board and the upper and down layers of collection cases are connected to cathode and anode resin tubes through tubes. The collection method is to grow plant in the growth case earth and then to pass film into collected case with quartz and glass balls and then to process and collect plant stem secretion inside collection case.

Description

technical field [0001] The invention relates to the field of collecting plant root exudates, in particular to a method and a collecting device for collecting plant root exudates under soil cultivation conditions. Background technique [0002] At present, the solution collection method is generally used to collect plant root exudates. The specific operation method is: the plant roots first grow in the nutrient solution, and then transfer to the treatment solution. After a period of treatment, the collected treatment solution is the root exudates. The root exudate collection device of Chinese patent CN2581964YHE and CN1482443A design. The solution collection method is widely used because of its simple operation and convenient analysis. However, the root exudates obtained by the solution collection method can hardly reflect the actual situation of plant root exudates under soil conditions. This is mainly due to: complex soil composition, diverse forms of nutrients, uneven dis...
