Problems solved by technology

There are 4 disadvantages in this method, which will affect the survival rate of the crust: the first disadvantage is that the moss crust may damage the crust tissue during the shade drying process, which will affect the survival rate; the second disadvantage is that the plant grinder When crushing the crust, it will also generate heat, which may burn the stem and leaf fragments of the crust; the third disadvantage is that the structure of the blade in the pulverizer will damage the moss crust tissue, which will affect the survival rate; the fourth disadvantage is the use of plants When crushing moss crusts, the shredder can only control the crushing time and then control the size of the stem and leaf fragments. The process is cumbersome and may lead to the death of the crust stem and leaf fragments
It can be seen that the moss crust stem and leaf fragments obtained by the above method are difficult to avoid damage to the crust, which not only takes a long time, but also significantly affects the survival rate of the crust

Embodiment 1

[0033] Field collection thickness is 2.65mm, plant density is 20 plants / cm 2 1. For sand moss crust samples in good growth condition, place them in a cool place away from light to 14%, so that the crust and soil can be separated easily. Gently rub the sand moss crust samples with your hands to make the sand moss crust samples and soil preliminary Separation, pass the sand moss crust sample through a 120-mesh soil sampling sieve, and spread the sieved crust stem and leaf fragments in time for planting, the inoculum amount is 500g / m 2 , cover the sunshade net, the temperature is controlled at 20°C, the light is outdoor natural light, watered regularly, the soil moisture content is controlled at 28%, and the sand moss crust is obtained after cultivating for 7 days.

Embodiment 2

[0035] Field collection thickness is 2mm, plant density is 25 plants / cm 2 1. For sand moss crust samples in good growth condition, place them in a cool place away from light to 12%, so that the crust and soil are easier to separate. Gently rub the sand moss crust samples with your hands to make the sand moss crust samples and soil preliminary Separation, pass the sand moss crust sample through a 130-mesh soil sampling sieve, and spread the sieved crust stem and leaf fragments in time for planting, the inoculum amount is 450g / m 2 , cover the sunshade net, the temperature is controlled at 22°C, the light is outdoor natural light, watered regularly, the soil moisture content is controlled at 25%, and the sand moss crust is obtained after cultivation for 8 days.

Embodiment 3

[0037] Field collection thickness is 3mm, plant density is 15 plants / cm 2 1. The sand moss crust sample in good growth condition should be placed in a cool place away from light to 15%, so that the crust and soil can be separated easily. Gently rub the sand moss crust sample with hands to make the sand moss crust sample and the soil preliminary Separation, pass the sand moss crust sample through a 110-mesh soil sampling sieve, and spread the sieved crust stem and leaf fragments in time for planting, the inoculum amount is 530g / m 2 , cover with a sunshade net, the temperature is controlled at 18°C, the light is outdoor natural light, watered regularly, the soil moisture content is controlled at 30%, and the sand moss crust is obtained after cultivating for 10 days.

Abstract

The invention provides a rapid cultivation method of moss crust, and belongs to the technical field of environmental engineering. The rapid cultivation method of the moss crust comprises the following steps: placing a collected moss crust sample in a shady place away from light, kneading, sieving to obtain crust stem and leaf fragments, and spreading and cultivating for 7-10 days to obtain the moss crust. By means of the cultivation method, the crust tissue can be prevented from being damaged to the maximum extent, the survival rate of the crust tissue is increased, the size of moss crust stem and leaf fragments can be effectively controlled according to the requirements of researchers, and the crust development time is greatly shortened. Experimental results show that by means of the cultivation method, the survival rate of the moss crust can reach 100%, and the moss crust can be formed within 7 days at most.

Description

technical field [0001] The invention belongs to the technical field of environmental engineering, and in particular relates to a method for rapidly cultivating moss crusts. Background technique [0002] Moss crust is a complex formed by mosses, microorganisms and soil, and its presence changes the physical and chemical properties of soil, making it significantly different from the crust-free coverage area. Moss crust is the dominant type of biological crust, and its role in water conservation, windbreak and sand fixation is far greater than that of lichen and algal crust. The appearance of mossy crusts marks the advanced stage of biological crusts development, which represents the benign development of the ecological environment. The existence and amount of moss crusts are indicative for maintaining the stability of the local ecological environment; they can also guide the use of moss crusts for artificial sand control and prevention of further desertification. Bryophytes ...
