Description
Technical field
What the present invention relates to is a kind of aquatic plants growth apparatus and method, the apparatus and method of especially a kind of water level depth of water, water quality, bed mud variable effect aquatic plants growth.
Background technology
Submerged vegetation has purifying water body, improves the important function of water quality, and it is grown main nutrition salinity and temperature, the under water light intensity, water nutrition, bed mud etc. of being subject to expansion and affects.
The only photosynthetic energy source of submerged plant, light intensity deficiency or shortage submerged plant are difficult to grow, grow under water, and submerged vegetation can be caused to disappear, and then can cause water quality deterioration, algae etc. grow fast, bring serious environmental problem, even disaster.Light intensity is except being limited by the transparency of reflection lake water quality quality under water, also by the distance controlling of dried up of water body; When water transparency is certain, water body is larger apart from the distance of the water surface, and wherein light intensity is more weak under water; Otherwise, more stronger close to water surface light intensity.At the submerged plant development growth initial stage, determine that its key element grown is just lakebed light intensity, light intensity magnitude is directly determined by the depth of water, and the depth of water larger lakebed light intensity is more weak, and the depth of water lakebed light intensity that diminishes increases.When lake landform does not change, water level is the sole determinant of the depth of water.
Therefore, SEA LEVEL VARIATION will produce material impact to submerged vegetation.In recent years, because of construction and the water project operation of lake basins and periphery river construction thereof, the intrinsic variation characteristic of lake level there occurs great variety, and this change both may produce positive influences to submerged plant and submerged vegetation, also may have a negative impact; This impact is not because coming into one's own and studying, not clear, under the very serious situation of current Water Environment In Lakes problem, carry out the research that SEA LEVEL VARIATION affects lake submerged vegetation, take precautions against water level management to Taihu Lake submerged vegetation adverse effect and harm, just seem very urgent and important, and have important practical significance.
Substantial connection is then there is between the how many and water quality of the nutritive salt that plant can obtain, bed mud, when nutrient salt in water and the supply of bed mud Middle nutrition salt are suitable for, water plants can vigorous growth, and when water body and bed mud Middle nutrition salt too much or very few time, aquatic plants growth will be limited, even occurs withering death.
The method studying submerged plant growth in prior art is carried out on land, after plant growth a period of time, after needs dig out plant to come from earth, observation of plant root growth situation, be unfavorable for plant survival and continue to observe, and be simulate submerged plant growth situation on land in prior art, be difficult to observe contrast different water depth, water quality, the upgrowth situation of bed mud situation cascading water plant and change.
Summary of the invention
The present invention proposes a kind of water level depth of water, device that bed mud, change of water quality affect aquatic plants growth, it is characterized in that comprising cross planting groove, fixed support; Fixed support comprises crossbeam, column, and support bracket fastened crossbeam is directly fixed on column, and column is fixed in water-bed mud; Cross planting groove is fixed on support bracket fastened floating bracket crossbeam by tether in water, the blackboard layer that cross planting groove comprises, transparent organic glass layer and rivet, perspex layer splicing surrounds the cross planting groove of upper opening, planting groove is equipped with mud, the cross-tie played the role of fastening) between perspex layer, the blackboard layer preventing pipeline from injecting is positioned at outside perspex layer, and by several rivet and the tight fixed engagement of perspex layer.
Further improvement is: comprise floating bracket, and cross planting groove is fixed on the crossbeam of floating bracket by tether in water; Crossbeam is connected to water and floats top; Water is floating to be connected on column by iron hoop, and column is fixed in water-bed mud.
Based on the method that water level water depth ratio, bed mud, change of water quality affect the measurement device water level depth of water of aquatic plants growth, bed mud, change of water quality affect aquatic plants growth, bed mud on multiple planting grooves of device are in-built;
Water plants is planted in the planting groove of device;
Floating bracket and fixed support is set up in water body; The crossbeam being fixed on floating bracket can be elevated with SEA LEVEL VARIATION, and is fixed on support bracket fastened crossbeam and is not elevated with SEA LEVEL VARIATION.
Respectively by each for the planting groove of plant one or more be separately fixed at below different floating brackets and fixed support crossbeam water by tether in ad-hoc location;
Identical or different bed mud can be loaded as required in planting groove in above-mentioned steps, plant identical or different plants, the tether length be connected with planting groove experimentally object changes and regulates, planting groove puts into identical or different water quality as required, and select fixed support and floating bracket as required, the combination free setting with the need of above-mentioned various change, by observing the different water level depth of water, bed mud, phytomass in planting groove after change of water quality, root, stem, the leaf difference determination water level depth of water, bed mud, change of water quality is on the impact of water plants.
The present invention adopts lucite to do planting groove, after therefore removing the blackboard of perspex layer outside, clearly can see the upgrowth situation of submerged plant root system, not hinder submerged plant root system, be conducive to observing its upgrowth situation further; The device that water level water depth ratio affects aquatic plants growth is criss-cross structure, more steady in water, and it can be planted the plant of different group, is convenient to carry out observation contrast to its growth; Its water arranged is floating can fluctuate on column, by being fixed on comparing of the device of lakebed staking out with crossbeam, can be easy to measure SEA LEVEL VARIATION to the impact of plant, by the comparison of planting groove in different bed mud, water quality, the impact on plant growth of different bed mud, water quality can be seen.
