Problems solved by technology

This device cannot simulate the in-situ growth environment of rock plants. During the cultivation process, the plant roots are in an anaerobic environment for a long time. The active substances collected cannot represent the conditions of the normal growth of plants. Only root exudates can be collected, and it is difficult to collect circulating fluid. Studying the ability of root exudates to transform rock nutrients

Embodiment Construction

[0013] The device for collecting rock plant root exudates and circulating fluid of the present invention includes a plant culture dish 1 with a sterile culture film 5 at the upper mouth, a funnel 2 connected to the lower part of the plant dish 1, placed in the plant culture dish 1 and cut vertically and evenly A cylindrical stone body 3 formed into four pieces, a liquid level gauge 4 arranged on the side wall of the petri dish, a circulating fluid collecting column connected to the lower end of the funnel 2, a resin collecting column 6 connected to the lower end of the circulating fluid collecting column, and a resin collecting column 6 connected to the lower end of the circulating fluid collecting column. The other end of the column 6 is connected to and extends into the connection pipe 20 on the stone body 3 , the communication pipe 7 connected to both ends of the resin collection column 6 , and the air pump 8 arranged on the connection pipe 20 . Wherein, the circulating flui...

Abstract

The present invention provides a root system secrete and circulating fluid collecting equipment and collecting method. Said invention is formed from two portions of plant culture and root system secrete and circulating fluid collection. The plant culture portion includes culture dish, stone body whose longitudinal direction is uniformly cut and funnel, and the root system secrete and circulating fluid collecting portion includes circulating fluid collecting column, resin collecting column, charging pump and connecting tube. Said invention also provides the concrete steps of said collecting method.

Description

technical field [0001] The invention relates to an analysis device and method, in particular to a device and method for collecting rock plant root exudates and circulating fluid. Background technique [0002] During the growth process of rock plants, in order to adapt to the special habitat with poor nutrients and frequent changes in ecological factors, their roots continuously secrete a wide variety of active chemical substances into the rhizosphere environment, mainly including inorganic ions and organic compounds, except for cell exfoliation and mucus. In addition, the rest of the rhizosphere substances are soluble substances, collectively referred to as root exudates, of which 4-7% enter the interior of the rock to promote the activation and migration of nutrients in the rock. Studying the ability of rock plant root exudates and transforming and migrating rock nutrients is an important part of studying plant nutrition, allelopathy and rhizosphere microecology.
