Embodiment 1

[0030] The ecosystem simulated in the study is a semi-daily tidal beach wetland, that is, the tide rises twice a day and the tide ebbs twice a day. Set daily high tide at 5:00AM, low tide at 11:00AM; high tide at 17:00PM, low tide at 23:00PM. The water depth is 50cm at the highest tide level and 20cm at the lowest tide level, that is, the water level rises from 20cm to 50cm at high tide and drops from 50cm to 20cm at low tide. The salinity of the cultivation water is 1.5%. The area of ​​the cultivation room is 10m×10m.

[0031] step:

[0032] (1) Plant different plants at three tidal levels in the cultivation room, such as planting Salmonella salsa at the low tide level, planting Suaeda salsa at the middle tide level, and planting reeds at the high tide level.

[0033](2) Fix the highest water level probe 14 to a height of 50 cm from the bottom of the open tank 15, and fix the lowest water level probe 16 to a height of 20 cm from the bottom of the open tank. Set the A circ...

Embodiment 2

[0040] In the initial stage of system operation, the total water storage capacity of the system is 60 cubic meters, and the actual maximum water consumption of the cultivation room is 50 cubic meters. Considering the pumping demand of the water pump, when the overall water volume in the system drops below 55 cubic meters, it cannot be guaranteed that the maximum water level in the cultivation room can meet the experimental requirements. After a period of operation of the cultivation system, due to plant absorption, transpiration, evaporation, etc., the amount of circulating water in the system decreases and the salinity increases. It is necessary to adjust the water amount and salinity of the system to meet the experimental requirements.

[0041] step:

[0042] When the cultivation box was at the lowest tide level period (that is, the water level was 20cm), through the observation window of the water tank, it was recorded that the water storage volume in the water tank was 33 ...

Abstract

The invention relates to a walk-in plant cultivation system simulating the intertidal water level. The system is composed of a cultivation chamber, a control system and a water tank, the cultivation chamber adopts wall-in design, multiple cultivation areas, footpaths, open channels and other facilities are planned, indexes such as the water level, salinity and water quality can be monitored, sampling, plant processing and the like are implemented in the cultivation chamber, the multi-processing and multi-repeating research demand can be met, in the cultivation chamber, different cultivation areas are divided through ecological bricks, the smooth water flow among different areas is achieved, but a medium cannot be rushed to a low tidal region from a high tidal region due to the water flow.

Description

technical field [0001] The invention relates to the research on the distribution and succession of plant communities in the intertidal zone, in particular to a walk-in planting system for simulating the water level in the intertidal zone. Background technique [0002] The coastal intertidal zone refers to the coast or coastal tidal flat between the highest tide level and the lowest tide level during the spring tide. It is the seawater ebb and flow zone between the high tide line and the low tide line. According to the law of tidal activity, the intertidal zone can be divided into high tide zone, mid tide zone and low tide zone. The intertidal zone is regularly flooded and exposed by water, and the physical and chemical properties of the environment also show diurnal variations with the tides. Since the time and depth of inundation of different elevation areas by tidal water are different every day, the environment of the intertidal zone has obvious gradient changes, and the...
