Efficient propagation method for sandy moss provenance

Abstract

The invention provides an efficient propagation method for sandy moss provenance, and relates to the technical field of environmental engineering. The method comprises the following steps: taking mosscrust naturally developed in a Mu Us Desert sand land as the provenance, taking disinfected sandy soil as a matrix, adding actinomycetes and chlorella, and inoculating and crushing the sand moss provenance, wherein only 0.24 m<2> of field moss provenance is needed, 1 m<2> of stable moss crust can be cultivated and formed within 30 days under the condition of an incubator, and 4-time propagation is achieved; and the cover degree, the plant density and the plant height respectively reach 97.14%, 28.31 plants/cm<2> and 2.28mm. The method is an effective method for efficiently cultivating the sandy moss crust under the condition of manual control, provides reference for factory propagation practice of the moss provenance in the future, and lays a foundation for solving the bottleneck problemof insufficient field engineering provenance recovery of the moss crust.

Description

technical field [0001] The invention belongs to the technical field of environmental engineering, and in particular relates to a method for efficiently multiplying sand moss provenance. Background technique [0002] Biological soil crusts are widely distributed in arid-semi-arid areas, especially in areas where vascular plants are difficult to survive, and are of great significance to the maintenance of local land resources and ecological environment protection. However, desert biological crusts are extremely vulnerable to damage, and once destroyed, it will accelerate the process of desertification. Depending on the size of the crust, the natural recovery time of a complete crust ranges from a few years to more than ten years, and the cycle is long. [0003] At present, the provenance of mossy crusts required for the restoration of mossy crusts is collected from the wild, and the local ecological environment will inevitably be damaged in the process of collecting provenanc...

AI Technical Summary

Problems solved by technology

[0003] At present, the provenance of mossy crusts required for the restoration of mossy crusts is collected from the wild, and the local ecological environment will inevitably be damaged in the process of collecting provenances. The effects of physical factors such as inoculum amount or chemical factors such as nutrient solution and growth regulator on the cultivation of moss crusts are mostly concentrated in the Loess Plateau area and desert research areas such as Xinjiang and Ningxia. The bryophytes that have a significant windbreak and sand-fixing effect on the Mu Us Sandy Land And there are few reports on using biological factors such as fungi and algae as additives to promote the growth and development of mossy crusts

At the same time, there is currently no method that can meet the huge amount of provenance required for field engineering restoration through artificial large-scale propagation.
