Collecting device and method of root exudates from xerophyte

Abstract

The invention provides a collecting device of root exudates from xerophytes. The collecting device comprises a cultivating bucket, wherein the bottom surface of the cultivating bucket is communicated with a rubber tube, and the other end of the rubber tube is connected with an injector, a soil vermiculite mixed culture medium layer and a filter layer are sequentially spread in the cultivating bucket from top to bottom, and an irrigation tube is further arranged in the cultivating bucket. The invention also provides a collecting method for the root exudates from xerophytes, which is designed according to the collecting device. The collecting device and method are suitable for research on plants under soil cultivation condition, especially the root exudates from xerophytes; compared with water-culture or simple medium cultivation method, the method provided by the invention has the advantages that the actual condition of the root exudates from xerophytes under the natural condition can be better reflected; meanwhile, the collecting device cannot disturb the root growth or damage the rhizoapple environment in the premise of guaranteeing the normal growth of the plant, and the root damage and bleeding disturbance caused by collecting the root exudates through a traditional earth culture method are avoided.

Description

technical field [0001] The invention relates to a device for collecting xerophyte root exudates and a collecting method thereof. Background technique [0002] At present, the collection of root exudates mainly includes hydroponics, matrix culture collection, and soil culture. Hydroponics does not require special collection devices, but hydroponic plants generally have less root hair development and no mechanical resistance, which is quite different from the aeration, nutrient distribution, and root branching structure grown under real soil culture conditions. Therefore, hydroponics cannot obtain the root exudates of xerophytes. The matrix culture method can ensure the ventilation of the root system and has a certain mechanical resistance, but it is quite different from the root exudates in the natural state. [0003] The traditional soil culture method mainly adopts two methods to collect root exudates. One is to take out the root system of the soil culture plants after gr...

AI Technical Summary

Problems solved by technology

This device can neither destroy the natural growth condition between the root system and the soil, but also can better select the collection site, but it cannot collect the root exudates of tubers or tubers

[0004] In summary, none of the currently used root exudate collection devices are suitable for the collection of xerophyte root exudates, which greatly limits the research on xerophyte root exudates
