The pedestal is net cage, and clump weight is equipped in the net cage, places the feeding cylinder mould on the clump weight.
The clump weight is stone.
The feeding cylinder mould has multiple, is divided into N number of aperture set, N is the integer more than or equal to 2, and each aperture set has
At least one described feeding cylinder mould, the aperture of the feeding cylinder mould is identical in each aperture set, the different aperture sets
The aperture of the feeding cylinder mould is different.According to the feeding cylinder mould of setting different pore size, the biology that can study different-grain diameter simultaneously is right
In the influence of organic matter degradation.Every group when containing greater than 1 feeding cylinder mould, it is raw can also to study same particle size in different time simultaneously
Degradation rate of the object to organic matter in river.
It include three feeding cylinder moulds in each aperture set.
N is 3, includes 3 feeding cylinder moulds in each aperture set, the aperture of feeding cylinder mould is respectively in each aperture set
0.002mm, 0.042mm and 0.5mm.
The organic substrates are cotton strap.
The material of the feeding cylinder mould is metal or hard macromolecule.The feeding cylinder mould of metal or hard high molecular material tool
There are corrosion-resistant, water-fast, wear-resisting, high temperature resistant, weatherability, will not fail in the course of the research, also can guarantee the steady of aperture
It is fixed.
Buoy is also connected with above the pedestal.The buoy of setting finds placement location convenient for the later period.
Using above-mentioned apparatus, tested in the old Jun Mountain area in Yunnan.
The old Jun Mountain in Yunnan is located in Hengduan mountain range south section, props up in Yunling, is in half moon, by magmatic rock and Trias sand shale
Deng composition erosion mountains, 4247.2 meters of main peak, afforestation rate separately has 20% or so high mountain grassland, grassy marshland up to 70% or more, is
Chinese primary ecology system saves one of the most intact and global most representative ecosystem.Old Jun Mountain backbone line east northeast side
In 3800 meters of height above sea level or more of hawthorn, there are lake, marsh dozens of, is distributed along streams bunchiness.The old good natural environment of Jun Mountain
Field trial is carried out for us, and good condition is provided.According to research needs, we along streams by height above sea level from 1820 meters to
4050 meters, 33.5 kilometers of span, about 20 sampled points have been selected to be tested for a height above sea level interval with 110 meters.
Specific experiment includes the following steps and (can also be operated according to the general operation method of those skilled in the art):
(1) cotton strap is got out, is cut into the rectangular item of 3cm*7cm size as needed, in order to reduce current scour etc.
Influence of the physical action to cotton strap weight, needs to modify the line of cotton strap surrounding, and rear high-temperature sterilization is numbered to cotton strap
Drying weighing.Cotton strap is put into the feeding cylinder mould of different pore size before experiment, sets 0.002mm, 0.042mm and 0.5mm altogether
Three kinds of different apertures, every kind of aperture are set there are three feeding cylinder mould, (place 24 hours with adhesive sealing to obtain maximum glue
Knotting strength), so that feeding cylinder mould is formed a closed area.Since most of streams are shallower, in order to make net cage be completely immersed in small stream
In stream, the net cage size of this experimental design is 20cm*45cm*65cm.
(2) relatively flat region is selected to be repaired in streams when unevenness with spade in streams as experiment porch
It is whole.Net cage is installed and is placed on the experiment porch chosen in advance, several blocks of more smooth stones is selected to insert net cage to surface
It is smooth, for increasing the stability of net cage, to prevent net cage from being washed away by stream, the stone table that feeding cylinder mould is put into net cage
Buoy is fastened in face on net cage, is found convenient for the later period and is placed site.
(3) after device is provided with, a sample was taken every ten days, experimental period is one month, to detect in different time
Degradation rate of the different-grain diameter biology to organic matter in the degradation rate and same time of organic matter.The tool scissors such as scissors when sampling
Taking-up cotton strap is used after opening feeding cylinder mould, is carried out further with being put into impregnate in sterile distilled water after its surface mass of alcohol rinse
Cleaning, be put into after cleaning up in baking oven dry after weigh, by experiment front and back organic substrates weight change, calculate obtain with
Different-grain diameter biology is to organic matter in influence and same time of the time change same particle size biology to degradation effect of organic compound
Degradation rate.
Experimental result are as follows: feeding cylinder mould aperture is bigger, and the consumption of cotton strap is bigger；As time increases, cotton strap
Consumption present first reduce after the state that gradually tends towards stability.To different-grain diameter biology in the old Jun Mountain streams in Yunnan to organic matter
The result of study of degradation shows that the experimental provision operational excellence, high stability can stop the influence of very fast flow velocity, conducive to taking
Band and be easily installed.
