Problems solved by technology

[0006] In the prior art, the method of studying the growth of submerged plants is carried out on land. After the plants grow for a period of time, the plants need to be dug out from the soil to observe the growth of the plant roots, which is not conducive to the survival of the plants and continued observation. In the existing technology, the growth status of submerged plants is simulated on land, and it is difficult to observe and compare the growth status and changes of submerged plants under different water depths, water quality, and sediment conditions

Embodiment 1

[0020] Such as Figure 1-3 As shown, the present invention proposes a device for water level and water depth changes, water quality, and bottom mud to affect the growth of aquatic plants, including a cross-shaped planting groove and a fixed bracket; the fixed bracket includes a beam 8 and a column 5, and the beam 8 of the fixed bracket is directly fixed on the On the column 5, the column 5 is fixed in the mud at the bottom of the water; the cross-shaped planting groove is fixed on the floating support beam 8 of the fixed support through a tether in the water, and the blackboard layer 1, transparent organic glass layer 2 and rivets included in the cross-shaped planting groove 4. The plexiglass layer 2 is spliced ​​to form a cross-shaped planting tank 3 with an upper opening. The planting tank 3 is filled with mud 10. The horizontal tie rod 9 for fastening is located between the plexiglass layers 2 to prevent the pipeline from entering the blackboard layer 1. It is located outsi...

Embodiment 2

[0023] Install different sediments in multiple planting tanks of the device; plant the same kind of aquatic plants in the planting tanks of the device; set up fixed supports in different water quality water bodies; the floating beams with water floats can rise and fall with the change of water level, And the fixed crossbeam does not rise and fall with water level change; Each one or more of the planting grooves 3 with the same bottom mud and the same plants are fixed in the water by different lengths of tethers to different specific positions in the same water quality below the floating crossbeam; the planting grooves 3 is fixed on the beam 8, and the beam 8 is indirectly fixed on the column at the bottom of the lake. When the water level changes, the water float 7 will float in the water with the increase of the water level, and drive the floating beam 8 to move up and down, thus making the planting groove on the floating beam The position of 3 in the water changes with the ri...

Embodiment 3

[0025] One or more of the planting troughs of the same bottom mud and the same plant are respectively fixed on the floating beam and the fixed beam with the same length of tethers at the same time, and placed in the same water quality; the planting trough 3 on the fixed beam is when the water level changes When the water depth changes with the water level, the water depth of the planting trough fixed on the fixed beam and the floating beam with the same length of tether will be different, which will lead to differences in the growth of plants planted in the planting trough, and this difference will be Reflects the effect of water level changes. The impact of water level changes on aquatic plants is determined by the differences in plant biomass, roots, stems, leaves, etc. in planting tanks fixed on floating beams and fixed beams, and the characteristics of water level changes.

Abstract

The invention discloses a device and a method for influencing aquatic plant growth by water level, water depth, water quality and bottom material changes. The device comprises cross-shaped planting troughs, a fixed bracket and a floating bracket, wherein each cross-shaped planting trough comprises a blackboard layer positioned at the outer part and an organic glass layer positioned on the inner side of the blackboard layer; the organic glass layers are spliced and formed into the cross-shaped planting troughs of which the upper parts are open; the blackboard layer is positioned on the outer side of the organic glass layer, and is tightly and fixedly jointed with the organic glass layer through rivets. According to the invention, organic glass is adopted to make the planting troughs, the growth condition of the submerged plant root system can be clearly observed, the submerged plant root system is not hurt, and further observation of the growth condition of the submerged plant root system is facilitated; the device adopts the cross-shaped structure, and is relatively stable in water; the two groups of same planting troughs are respectively hung under the fixed bracket and the floating bracket, so that the influence on plants by the water depth change can be easily measured; the planting troughs are filled with different bottom materials, when the planting troughs are hung on a cross beam of the fixed bracket or the floating bracket, the influence on the plants by different bottom mud can be easily measured, and influence on plants by the water quality can be measured when the planting troughs are put into different water bodies.

Description

technical field [0001] The invention relates to a device and method for growing aquatic plants, in particular to a device and method for affecting the growth of aquatic plants due to changes in water level, water quality and sediment. Background technique [0002] Submerged vegetation plays an important role in purifying water and improving water quality. Its growth and expansion are mainly affected by nutrients, temperature, underwater light intensity, water nutrients, and bottom quality. [0003] Light is the energy source for photosynthesis of submerged plants. Insufficient light intensity or lack of submerged plants is difficult to develop and grow, which can cause the disappearance of submerged vegetation, which in turn will lead to deterioration of water quality and rapid growth of algae, etc., causing serious environmental problems. , and even disasters. The underwater light intensity is not only subject to the transparency reflecting the lake water quality, but als...
