(3) plant leaf blade photosynthetic parameters are analyzed
Respectively in May, 2016, July and October, the curve responded to the Photosynthetic of 13 kinds of test plant blades (Fig. 3), therefrom draws the main photosynthetic parameters of plant, including light saturation photosynthetic rate (Psat), Dark respiration rate (Rd), Light saturation point (LSP), light mend point (LCP) and AQY (φ) etc., wherein most important parameter is Psat, can disclose plant Thing photosynthetic capacity and its to CO2Assimilation it is horizontal.The data of specific 13 kinds of test plants photosynthetic parameters seasonal variations As shown in table 4:
4 13 kinds of test plant photosynthetic parameters seasonal variations (mean ± SD, n=3~9) of table
As seen from Table 4, May is plant growth vigorous season, and the Psat of every kind of plant shows high value, over time Passage, enter high temperature extremely hot season July, the Psat of plant totally occur it is slight reduce trend, the range of decrease most notably emerald green reed Jasmine and angel spend;Enter autumn to October, some plant leaf blades start gradually withered and yellow, and growth slows down, and Psat is also in decline state. There are the species such as giantreed, orris, cyperus alternifolius and calamus in obvious seasonal variations;Species of the Psat without obvious seasonal variations has water Opium poppy, great Ye imperial crowns grass, spring taro, thaliadeabata, canna etc..According to each season average result, the Psat of 13 kinds of plants by height to Low sequence is respectively:Thaliadeabata > water opium poppy > cattail > angels spend > cyperus alternifolius > canna > kingfisher Lu Li > giantreed > great Ye Imperial crown grass > calamus > orris > spring taro > Alocasia ordoras.Thaliadeabata and water opium poppy apparently higher than other species (P < 0.05), other Plant higher Psat is cattail, Tian Shihua, cyperus alternifolius, canna, emerald green Lu Li, giantreed, great Ye imperial crowns grass and calamus;Iris Grass, spring taro and Alocasia ordora, which are surveyed, is substantially less than above preceding species, belongs to typical shade plant.Therefore, when carrying out plant adaptability screening, The seasonal variations and phenology feature of plant are contemplated that, carry out different plants configurations according to specific environment.
According to Pearson correlation analyses, there is extremely significant positive relation (P < 0.01) in Psat and LSP and Rd, from table 4 It can be seen that light saturation point (LSP) has larger difference, between 516.79-1435.93, reaching more than 1000 has 6 kinds of plants Thing, it is respectively that thaliadeabata > water opium poppy > kingfisher Lu Li > giantreed > calamus > angels spend from high to low;LSP it is relatively low be Canna > great Ye imperial crown grass > orris > Alocasia ordora > spring taros.The Dark respiration rate (Rd) of plant compares Psat, and its value is obvious Smaller, luffing is less big, and for the Rd of 13 kinds of plants between 0.68-2.36, its reclaimed water opium poppy, angel spend the Rd phases with thaliadeabata To higher, the Rd of spring taro, orris and Alocasia ordora is low compared with other species.
Cluster analysis (Fig. 4) is carried out using Psat, LSP, Rd as variable, if being carried out by plant Psat, LSP and Rd feature Compressive classification, the species for belonging to high Psat, LSP and Rd have:Thaliadeabata, water opium poppy, cattail, Tian Shihua, cyperus alternifolius, canna and big Leaf imperial crown grass;Psat, LSP and Rd relatively low species has:Alocasia ordora, spring taro, orris, calamus, emerald green Lu Li and giantreed.
Cluster analysis more than shows, two monoids, thaliadeabata, water opium poppy, cattail, day can be roughly classified into 13 species Make flower, cyperus alternifolius, canna and great Ye imperial crown grass etc. are more positive non-hibernating eggs classes, are adapted in sun-drenched grown, or plant Upper strata species when different levels configure, and Alocasia ordora, spring taro, orris, calamus, emerald green Lu Li and giantreed can be planted in compared with shade tolerant Darker place, or can be as lower floor's species in plants configuration.
(4) plant leaf blade chlorophyll fluorescence parameters are analyzed
Chlorophyll fluorescence kinetics technology during leaf photosynthesis is determined absorption of the photosystem to luminous energy, transmission, Dissipate, distribute etc. has the function that uniqueness, compared with plant gas exchanges index, the reflection of chlorophyll fluorescence parameters more Plant " internality " feature, therefore the technology is referred to as determining that photosynthetic function is quick, undamaged probe.Plant chlorophyll Fluorescence parameter is to describe plant photosynthesis physiology and one group of conventional variable of photosynthetic physiology situation, and more typical parameter has maximum photochemical Learn quantum yield (Fv/Fm), the electron transmission quantum efficiencies of PS IIPhotochemical quenching coefficient (qP) and non-photochemistry are sudden Go out coefficient (NQP) etc., is important indicator of the research environment to ozone deplation degree.
The maximum light energy use efficiency of Fv/Fm reflection plants, this parameter will be obvious when by environment-stress for blade Reduce, seldom changed under normal condition, size is typically between 0.75-0.85.Size can reflect PS II The actual photochemical activity of reaction center.Specifically need to further it be analyzed with reference to phenology feature, specific 13 kinds of plant chlorophyll fluorescences The seasonal variations of parameter are as shown in table 5:
The seasonal variations (mean ± SD, n=3~9) of 5 13 kinds of plant chlorophyll fluorescence parameters of table
As seen from Table 5, various plants Fv/Fm in the different months equal unobvious of change (P > 0.05), 13 kinds of plants Fv/Fm between 0.74-0.83, in range of normal value, shows that the upgrowth situation of plant is good, is not affected by environmental factor respectively Stress.It is the important indicator for analyzing plant photosynthesis physiological property.13 kinds of plantsValue 0.16-0.37 it Between, it is in extremely significantly lower related (P < 0.01) to Fv/Fm, wherein thaliadeabata, water opium poppy, big integral shroud are careless, angel spends etc. It is higher, and spring taro, Alocasia ordora etc. are then relatively low.As seen from Table 5, the electron transmission of the species such as great Ye imperial crowns grass, orris, canna Quantum efficiency declines with the extension of implantation time, and therefore, this 3 kinds photosynthetic capacity may be suppressed.
NPQ is non-Photochemical quenching coefficient, and reflection is that the luminous energy that the reaction centers of PS II absorb is not used in photochemical electron The part transmitted and dissipated in the form of heat energy, the photosynthetic efficiency of the lower explanation plant of its value are higher.As seen from Table 5,13 kinds of plants The NPQ of thing is respectively from low to high between 1.11-3.04:Water opium poppy < angels spend < cattail < thaliadeabata < great Ye imperial crowns Careless < calamus < kingfishers Lu Li < orris < cannas < giantreed < spring taro < cyperus alternifolius < Alocasia ordoras, this result and other specification The result showed has same or like implication.
By the plant of environment stress, its photosynthetic organs can be reduced to light transformation of energy and utilization, so as to cause degree different Excitation energy is superfluous, when surplus, which excites, carries out the ability of harmless treatment to it still above photosynthetic organs, necessarily leads to a large amount of Active oxygen, cause Xanthophyll cycle and photo damage.Fv/Fm represents the Photochemical Efficiencies of PS II, is changed very little under non-stress condition, it is not Influenceed by species and growth conditions, but under the conditions of stress or injury, Fv/Fm is significantly reduced, therefore it is usually pressed down as light The complex injuries of PS II are measured under system or other stress conditions.
This result of the test shows that in the Various Seasonal of 13 kinds of plants after planting, its Fv/Fm does not significantly decrease, Illustrate that these plants can adapt to current bed mud TN, TP content overproof, especially TP contents severe overweight and organic nitrogen dirt Dye state.Although the numerical value of other indexs is there occurs some changes, such as the electron transmission quantum efficiency of Partial Species, non-photochemistry It is quenched the parameters such as coefficient to decline, its photosynthetic organs is reduced and is suppressed light transformation of energy and utilization, photosynthetic capacity, but plant is led to The regulation of itself is crossed, has adapted to current environmental pollution, and being capable of normal growth.Need further to analyze the life of various plants later Object amount filters out the excellent species of suitable sludge seeding to related parameter, comprehensive analysis such as growths.
Step 6: net dirty effect conclusion of the plant to bed mud:
By water opium poppy, emerald green Lu Li, great Ye imperial crown grass, spring taro, calamus, thaliadeabata, cyperus alternifolius, Alocasia ordora, U.S. any of several broadleaf plants and giantreed point Do not plant in filling in the growth case of creek bed mud, 3 mixed planting trial zones are set in addition, plants configuration is respectively:Angel Flower, calamus and Alocasia ordora;Orris, cattail and cyperus alternifolius;Great Ye imperial crowns grass, thaliadeabata and water opium poppy, different plants are to bed mud Clean-up effect is as shown in table 6:
Clean-up effect (mean ± SE, n=3) of the 6 different plants of table to bed mud
As a result show (as shown in table 6), planting plants are after 1 year, and difference is presented in the nutrient content of bed mud under different disposal The decline of degree, bed mud nitrogen removal rate between 2.65%-30.35%, wherein, the nitrogen removal efficiency highest of thaliadeabata (30.35%), emerald green Lu Li is minimum, and only 2.65%, very big difference be present, the bed mud TN clearances of different disposal are followed successively by:Again Power flower > calamus > spring taro > great Ye imperial crown grass > water opium poppy > canna > giantreed > cyperus alternifolius > great Ye imperial crowns grass+thaliadeabata + water opium poppy > orris+cattail+cyperus alternifolius > Alocasia ordora > angels spend+calamus+Alocasia ordora > kingfishers Lu Li.According to cluster analysis, show Denitrification of the 7 kinds of plants such as test plant thaliadeabata, calamus, spring taro, great Ye imperial crowns grass, water opium poppy, canna and giantreed to bed mud Ability is stronger.
For total tp removal rate of bed mud between 10.26%-32.95, clearance is followed successively by wind from high to low under different disposal Car grass > water opium poppy > calamus > great Ye imperial crowns grass+thaliadeabata+water opium poppy > orris+cattail+cyperus alternifolius > angels spend+calamus + Alocasia ordora > thaliadeabata > Alocasia ordora > great Ye imperial crown grass > canna > kingfisher Lu Li > giantreeds.According to cluster analysis, windmill is planted Grass, water opium poppy, calamus, great Ye imperial crowns grass+thaliadeabata+water opium poppy, orris+cattail+cyperus alternifolius, angel spend+calamus+Alocasia ordora, The dephosphorization efficiency of thaliadeabata, Alocasia ordora isotype to bed mud is higher.
In summary, TN and TP removal efficiency of the plant such as cyperus alternifolius, water opium poppy, calamus, thaliadeabata and spring taro to bed mud It is higher;3 kinds of plant mixed configuration patterns are relatively low to the TN removal efficiency of bed mud, and to TP removal efficiency then relatively It is high.
Embodiment 2
The present embodiment is carried out to thaliadeabata, great Ye imperial crowns grass, the water opium poppy clean-up effect that individually plantation and combinations thereof configures Research and analyse.
(1) contaminated more serious creek deposition bed mud is collected, multiplies and is placed in the container that underseal closes, mud height about holds Device it is high 2/3rds.
(2) following plant thaliadeabata, great Ye imperial crowns grass, water opium poppy, and three kinds of plants are planted respectively on the container to filler The 1 of thing:1:1 mixed configuration.
(3) three kinds of plant thaliadeabatas, great Ye imperial crowns grass, water opium poppy, it is 20cm × 20cm individually to plant seeding row spacing, and three kinds mixed It is 1 to close configuration plantation:1:1, seeding row spacing is all 20cm × 20cm.
(4) normal field management method management is pressed, keeps plant normally to grow, while periodically note running water keeps holding The high mud extraction face 2cm of device water level, it is modeled to the water body environment of plant growth.
The nutrients such as the total nitrogen, total phosphorus and organic carbon of bed mud are determined respectively after (5) one years, as shown in table 7;It is the thaliadeabata of table 7, big The clean-up effect (mean ± SE, n=3) of leaf imperial crown grass, water opium poppy and its compounding to bed mud
As can be seen from Table 7, different degrees of decline, thaliadeabata is presented in the bed mud nutrient content under variety classes plant Nitrogen removal rate to bed mud is that 30.35, great Ye imperial crowns grass is 13.94 to the nitrogen removal rate of bed mud, and water opium poppy is to bed mud Nitrogen removal rate is 11.89, and thaliadeabata, great Ye imperial crowns grass, water opium poppy mixed configuration are 5.97 to total tp removal rate of bed mud, because This, thaliadeabata, great Ye imperial crowns grass, water opium poppy mixed configuration are decreased obviously to the total nitrogen removal efficiency of bed mud.
In addition, the removal ability of the total phosphorus of great Ye imperial crowns grass+thaliadeabata+water opium poppy combined plant configuration is significantly lower than power again The total nitrogen removal ability that flower, great Ye imperial crowns grass, water opium poppy are independently planted.
Finally, it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention rather than the present invention is protected The limitation of scope is protected, although being explained in detail with reference to preferred embodiment to the present invention, one of ordinary skill in the art should Understand, technical scheme can be modified or equivalent substitution, without departing from the essence of technical solution of the present invention And scope.
