Description
Technical Field
The invention relates to the technical field of environmental engineering, in particular to a preparation method and application of a moss cortex.
Background
The biological soil crust layer is an important component in arid and semiarid ecological environments and influences the structure and the function of an ecological system. The biological soil crust is widely distributed in nutrient-poor areas between vegetation patches in arid and semi-arid regions, and can regulate and control the effectiveness and redistribution of water and the circulation process of nutrients in an ecological system. The biological soil crust also has the capabilities of fixing carbon and nitrogen, decomposing and mineralizing organic compounds, enhancing the stability of soil and reducing wind erosion and water erosion on the soil. The moss plant is the main component for fixing sandy soil crust, has small size and strong drought resistance, cold resistance and asexual reproduction capability. As the mixed crusts succeed in moss crusts, their absorption of soil nutrients begins to increase as the number of moss increases. Compete with algae, resulting in reduced algae abundance and biomass, and reduced blue algae abundance. Through the competition of the superiority and the disadvantage, only some species with strong adaptability and stress resistance survive after the algae are completely replaced by moss crust, and the abundance and the biomass gradually reach stability. Along with the increase of the sand-fixing vegetation time established in different years, the thinning trend of the composition of biological cortex granules is obvious, the contents of organic carbon, available nutrients and total nitrogen show a continuously increasing change rule, and especially moss plants settle and form moss cortex, so that a more powerful condition is created for the healthy development of a soil ecosystem. The moss biological crust layer is formed and retained for a long time in the sand wind environment, the content of fine particles can be increased, the soil humus characteristics can be improved, the content of mineral elements can be increased, the silicon-iron-aluminum rate can be reduced, and the moss biological crust layer plays a positive role in promoting the sand wind development. The moss has strong infiltration capacity. Soil with moss crust had the highest stability, then algae crust, then lichen crust, again, and soil stability of sand was the worst.
At present, as the ecological system of a coal mining area is seriously damaged due to the large-scale exploitation and development of coal resources, the ecological environment problem becomes an inevitable problem restricting the development of the coal mining area and the construction of the ecological environment, and particularly, open-pit mining causes a larger ecological environment problem. Therefore, the moss cortex prepared by the method is of great importance in improving the natural environment of the refuse dump under the combined action of the moss and the natural vegetation of the refuse dump to improve the wind erosion resistance, rain erosion resistance, water retention and soil fixation capacity of the ground surface.

Example 1
On a slope with a small amount of native moss at one place of a north mine refuse dump in north of Centel, six groups of different mutually-contrasted sample recipes are established, wherein each group consists of 9 sample boxes of 50cm multiplied by 50cm, and each sample box is fixed on the slope by four long chopsticks. Each group of sample boxes are a pair of tooth moss, a pair of mountain feather moss and a pair of mixed moss (mainly true moss, accompanied by Mount Yu Moss, moss capsularis, moss ceratosphaeus, moss solonchaensis, moss cucurbitacinus, moss qinghai) and arranged for three times of repetition. Firstly, the moss is put on a chopping board and cut up by a kitchen knife, different nutrient substances and water retention agents are added into each group of soil, the nutrient substances and the water retention agents are 34-35g and 19-21g respectively, and the specific groups are shown in the following table 1.
TABLE 1 pharmaceutical composition ratios for each group
The compound thickener is composed of xanthan gum food-grade thickener and agar, and the mass ratio of the xanthan gum to the agar is 1.
Then, a thickening agent is prepared and mixed with the moss, the mixture is stirred until the mixture begins to be viscous, and the mixture is spread on a test place to form a moss crust layer and grow the moss.
The ratio in the experiment is as follows: knop nutrient solution: 3g of calcium nitrate, 0.9g of potassium nitrate, 0.75g of magnesium nitrate, 0.75g of potassium hydrogen phosphate and 0.009g of zinc sulfate, wherein each medicine corresponds to 300ml of distilled water; 2g of water-retaining agent, wherein the ratio of the water-retaining agent to distilled water is 1:150; thickening agent: 3g of compound thickening agent, and the proportion of the compound thickening agent to distilled water is 1:100, respectively; 16.8g guar gum powder to 300ml distilled water; maltodextrin 15g, in a ratio to distilled water of 1:20; 20ml of corn syrup and the proportion of water is 1:15;23.9ml agar corresponds to 300ml distilled water.
And then carrying out comparison experiments on the cortex of the moss, covering a mulching film, a sunshade net, nutrient solution, the existence of algae and covering on the palm hairs, observing the growth influence of various factors on the cortex of the artificial moss, and carrying out experimental analysis on the cortex of the moss by extracting a small part of the cortex to observe the growth condition of the moss. The experimental formulations for each group are shown in table 2 below.
TABLE 2 recipes and Experimental procedures performed
6 groups of 54 sample frames are arranged on the slope surface of the southern refuse dump of the Virginia victoria of the Hewley of the Xilinguo union as research objects, artificially prepared moss crusts are arranged by different methods, and the following results are obtained by observation:
(1) Moss in the prepared moss crust layer successfully survives, the moss is tightly combined with soil, the moisture of the crust layer is well kept, and the moss has the advantages of strong asexual reproduction capability and no decomposition, so the moss grows on the slope of the refuse dump where the moss grows.
(2) The 1 group is arranged on the palm mat, although the palm mat is tightly combined with the palm mat, the palm mat is separated from soil, and the growth cannot be continued when the soil nutrition attached to the artificial preparation of the cortex dictamni is consumed.
(3) The 2 groups are provided with plastic cloth films with the best wind resistance and water retention, but the plastic cloth films have holes made by fixing wood chopsticks, but the plastic cloth films are seriously irradiated by the sun, and the temperature in the films is too high to be suitable for moss to grow.
(4) Compared with the group with a plastic cloth film and a sunshade net, the 4 groups are most seriously corroded by wind power, but because moss is not blown away under the action of adhesives such as a thickening agent, the experiment of the group is closest to the living environment of naturally growing moss in a waste dump, and the moss has the capability of continuously growing although being damaged to a certain extent by rainwater erosion.
(5) The 3 groups and the 5 groups have the best effect, have the sunshade net and nutrient substances in the nutrient solution, can be well combined with the soil and are not eroded by wind power and washed by rain water. Compared with 3 groups of samples, the effect of the algae added in 5 groups of samples is not very obvious, and probably because the algae added in too little slope water die after the water evaporates and dries and can not play a role in the arid environment, the cortex of the two groups of artificial moss can continue to grow.
(6) The 6 blank control groups have no adhesives such as thickening agents and the like, although the sunshade net exists, most of the sunshade net is blown away by wind, a small amount of residues are intercepted by the sunshade net and separated from soil, and the blank control groups have no sign of growth in a sample square frame.
(7) When the artificial moss cortex is prepared, soil attached to moss plays an important role, the adhesion of the artificial cortex can be enhanced, and the attached native soil is more favorable for the growth of moss in the future.
(8) By comparing the growth conditions of different groups of moss, the growth of the moss on the teeth is better than that of the Moss on the mountain and the mixed moss.
Example 2
Rain resistance test of moss
The slope inclination angle and the moss coverage of a refuse dump in a Cennuie Guo victory mining area are simulated, a thin ditch is dug around a 25cm multiplied by 50cm plastic box full of soil, the washing is simulated by changing the precipitation amount and the precipitation height to collect the running water and the soil, and the volume of the running water and mud mixture is measured by a measuring cylinder. And calculating the volume ratio of the mixed solution of the effluent and the mud to the precipitation to reflect the degree of the slope surface washed. The moss, knop nutrient solution, polyacrylamide, the composite thickening agent of the embodiment 1 and bentonite are mixed and then laid in soil in a plastic box to form a moss cortex, and then a rain resistance experiment is carried out. In the experiment, 3 moss coverage gradients (0 percent, 40 percent and 80 percent), 3 slope inclination gradients (the inclination angles are 45 degrees, 60 degrees and 75 degrees respectively), 2 precipitation height gradients (50 cm and 100 cm) and 3 precipitation gradients (500 ml/min, 1000ml/min and 1500 ml/min) are combined. The results of the rain resistance tests for each group are shown in Table 3 below.
Table 3 simulated rainfall scouring table under different conditions
The results show that the moss crust layer prepared by the method can obviously improve the capability of resisting the scouring of rainwater on the slope, and when the precipitation is less than 1000ml/min, the capability of resisting the scouring of the slope with the coverage of 80 percent is improved by times compared with the capability of resisting the scouring of the slope without the coverage of moss. When the moss coverage is more than 40 percent, the coverage is increased, although the scouring resistance of the slope surface can also be improved, the effect is not very obvious. When the moss coverage is the same, the rainfall height is increased, the rainfall amount is increased, and the slope inclination angle is increased, so that the scour resistance effect of the moss can be shown.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by the present specification, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
