Embodiment 1

[0031] Embodiment 1: A device for the study of allelopathy of plant root exudates, the structure of which is as follows figure 1 shown. The bottom of the donor plant cultivation pot 1 is connected to the connecting pipe 5 through the rubber stopper 4 with an opening in the center. One end of the connecting pipe 5 is connected to the bottom of the donor plant cultivation pot 1, and the other end is connected to the upper part of the recipient plant cultivation pot 7. mouth, the valve 6 is located on the connecting pipe 5; the bottom opening of the recipient plant cultivating bowl 7 is connected with the communicating pipe 10, and the other end of the communicating pipe 10 is connected to the upper opening of the donor plant cultivating bowl 1, and the connecting pipe 10 pipeline Inflatable port 11 is provided.

[0032] The donor plant cultivation pot 1 has a diameter of 25 cm and a height of 30 cm. A glass wool layer 3 is laid on the bottom of the donor plant cultivation pot ...

Embodiment 2

[0034] Embodiment 2: The structure is the same as in Embodiment 1, except that the bottom of the recipient plant cultivating pot 7 is connected to the connecting pipe 10 through a rubber stopper 9 with an opening in the center.

Embodiment 3

[0035] Example 3: Application

[0036] The method of using the above-mentioned device, that is, adopting the method of carrying out the research on the allelopathic effect of plant root exudates, the steps are:

[0037] 1. Add 25cm thick quartz sand 2 into the donor plant cultivation bowl 1 and plant donor plants on the quartz sand, add 2L of nutrient solution into the donor plant cultivation bowl 1 and cultivate for 3 days, at this time the valve 6 is closed.

[0038]2. Add 15cm thick quartz sand 2 in the recipient plant cultivation bowl 7, sow the seeds of the recipient plant, and cover the upper part of the quartz sand 2 with 2cm thick vermiculite 8 to play the effect of moisturizing.

[0039] 3. After the above steps, open the valve 6, so that the mixed liquid containing the root exudates of the donor plant in the donor plant cultivation bowl 1 flows into the recipient plant cultivation bowl 7 through the connecting pipe 5 at the bottom.

[0040] 4. After the liquid in th...

Abstract

The invention relates to a device for researching the plant root exudate allelopathy and an application method thereof. The device comprises a donor plant cultivation pot, a receptor plant cultivation pot, communicating pipes and a valve, wherein the bottom of the donor plant cultivation pot is communicated to the upper port of the receptor plant cultivation pot by the communicating pipe with the valve; the bottom of the receptor plant cultivation pot is communicated to the upper port of the donor plant cultivation pot by the communicating pipe provided with an inflation inlet in another pipeline; donor plants are planted in the donor plant cultivation pot; receptor plants are planted in the receptor plant cultivation pot; and mixed liquid comprising donor plant root exudates flows into the receptor plant cultivation pot and returns into the donor plant cultivation pot under the action of the airflow to form the liquid flow circulation. The invention solves the problems of long time consumption, large work load and low precision of the conventional device and method.

Description

technical field [0001] The invention relates to the research on the allelopathy of plant root exudates, in particular to a device and a method for studying the allelopathy of plant root exudates on surrounding plants (including individuals of the same species), and belongs to the field of plant science and ecology. Background technique [0002] The various substances secreted by plant roots to the external environment during life activities are root exudates, and the phenomenon that root exudates promote or inhibit the growth and development of surrounding plants (including individuals of the same species) and microorganisms is called allelopathy . The allelopathy of plants is an important part of the study of interspecific relationships. It has important guiding significance for the study of community structure, community succession, biological invasion, crop continuous cropping obstacles, and the development of biological pesticides and biological herbicides. Industrial p...
