Problems solved by technology

The process and contribution of submerged plant leaves and roots to nutrient uptake under different water column and sediment nutrient environments have not been resolved.
[0004] At present, there is no patent for the separation of roots and leaves of submerged plants. Faraday (1979) used silicone plugs to wrap the erect stems of the seaweed Zostera marina, and then sealed them

Example Embodiment

[0030] The structural details of the specific embodiment of the present invention will be described in further detail below with reference to the accompanying drawings. This embodiment is aimed at submerged plants of a certain size (here, seaweed, Thalassia hemprichii (Ehrenb.) Aschers. is taken as an example). The specific device can be adjusted in size according to the size of submerged plants, and should not be a limitation of the present invention.

[0031] Such as Figure 1 to Figure 3 As shown, the present invention discloses a non-destructive separation culture device for the roots and leaves of marine and terrestrial submerged plants, which includes an upper chamber 1 for cultivating seaweed leaves and above-ground stems, and an upper chamber 1 for cultivating underground stems and roots below the upper chamber 1. The lower chamber 2, the upper chamber 1 and the lower chamber 2 are separated by a bottom plate. The bottom plate is provided with a number of separation holes...

Abstract

The invention discloses a device for root-leave undamaged separation culture of ocean-land submerged plants, comprising an upper cavity for culturing plant leaves and terrestrial stems and a lower cavity which is arranged below the upper cavity and used for culturing underground stems and roots. The upper cavity and the lower cavity are separated through a bottom plate on which a plurality of separation holes for the penetration of plants are arranged; the upper cavity is in an upward opening structure; and the lower cavity is in a closed structure. The device can realize that water layers of the upper cavity and the lower cavity are not leaked under the condition of maintaining the healthy survival of submerged plants, and has good simulation effect, convenient use, simple and easy dismounting and repeated use. The invention further provides a culture method of the device for root-leave undamaged separation culture of ocean-land submerged plants.

Description

Technical field [0001] The invention relates to a device and method for separating the aboveground part (leaf and aboveground stem) and underground part (underground stem and root) of submerged plants. It is an indoor simulation experiment of ecology and is specially designed to study the nutrients of submerged plant leaves and roots. (Such as C, N, P, Si and other biogenic elements) or toxic and hazardous substances (such as heavy metals and other pollutants) intake and substance transfer rules. Background technique [0002] The submerged plants referred to in the present invention include higher underwater angiosperms with root, stem and leaf differentiation in freshwater and seawater, and large herb plants with root and leaf differentiation. [0003] Unlike other primary producers in the water body, such as planktonic algae and epiphytic algae, algae mainly ingest nutrients in seawater, while submerged plants can ingest nutrients in the water column through above-ground leaves a...
