Nested automatic water circulation plant branch and leaf salt tolerance experiment device and method

Abstract

The invention is applicable to the technical field of plant branch and leaf salt tolerance experiments, and provides a nested automatic water circulation plant branch and leaf salt tolerance experiment device which is characterized by comprising a support, a first water tank, a second water tank, a placement frame, planting bags, a drip irrigation device, a spray irrigation device and a separation layer, the first water tank is located in the support, and the second water tank is located in the placement frame; the second water tank is located in the first water tank, the planting bag is arranged on the second water tank through the placement frame, a separation layer used for separating branches and leaves from root systems of plants is arranged above the second water tank, and scale values are arranged on the first water tank and the second water tank. The salt solution in the first water tank is sprayed on plant branches and leaves through the sprinkling irrigation device, and the fresh water in the second water tank is irrigated into the soil in the planting bag through the drip irrigation device. The device can prevent the plant root system from being stressed by salt to influence the experiment result, and the reliability of the experiment result is improved; manpower work is reduced, time is saved, and the labor intensity of workers is reduced.

Description

technical field [0001] The invention belongs to the technical field of salt tolerance experiments of plant branches and leaves, and in particular relates to a nested automatic water cycle salt tolerance experiment device and method of plant branches and leaves. Background technique [0002] Marine disasters occur frequently in my country, and coastal vegetation is an important part of coastal ecological protection. Marine salinity is the main factor affecting the growth of coastal plants. It mainly affects plant roots through groundwater intrusion, seawater inundation during high tide or typhoon affects plants, spray splashes affect the stems and leaves of coastal plants, and salt spray affects the branches and leaves of coastal plants for a long time. At present, the research methods of plant salt tolerance are mostly based on indoor observation of salt stress treatment and the evaluation of plant growth status and physiological response under the growth conditions of salin...

Problems solved by technology

[0003] It has been found through research that the effects of salt stress on plants from the root system and branches and leaves are different, and the salt tolerance of some plant roots and branches is quite different, which shows that the salt tolerance of plants obtained from the salt stress applied to plant roots in the past is not the same. Can not fully represent the salt tolerance of plant branches and leaves

However, little is known about whether the roots, branches and leaves of different coastal plants have different salt-tolerant capabilities, and how much the salt-tolerant capabilities of the leaves are, which serious
