Desert dry and semi-dry turf transplantation and re-laying method suitable for roadbed construction

Abstract

A desert dry and semi-dry turf transplantation and re-laying method suitable for roadbed construction is that turf transplantation is performed before roadbed earthwork construction, turf re-laying is performed after the roadbed earthwork construction, and finally turf maintenance is performed. The turf transplantation step further includes turf selection, turf excavation, moving and flat laying, temporary planting and watering fertilization operations, and after earthwork activities and infrastructure are finished, the turf re-laying step further includes re-laying face leveling, temporary planted turf transportation, re-laying face fertilization watering and fertilization turf joint filling operations. The final turf maintenance step includes grazing prohibition, enclosure and insect and disease prevention. Soil seed bank resources existing in an original turf are fully utilized, the turf survival rate is high, the regeneration capacity is good, the construction speed can be improved, a construction period can be shortened, an ecological environment in a construction region can be quickly recovered, and resources are saved. The desert dry and semi-dry turf transplantation and re-laying method is simple and convenient to operate, low in maintenance cost and remarkable in revegetation restoration effect, can obtain high biological diversity and landscape naturalness, has very high cost performance and is beneficial for popularization and application.

Description

technical field [0001] The present invention relates to the technology of IPC international patent classification A01G7 / 06 for the treatment of growing trees or plants and prolonging the life of plants, and the technology of transplanting and utilizing turf that will be destroyed on the surface of roadbed base and borrow and spoil ground during construction, especially suitable for The desert arid and semi-arid turf transplanting back-paving method for roadbed construction is suitable for earthwork activities in desert arid and semi-arid areas of roadbed construction. Due to the damage of surface vegetation caused by external forces, it is necessary to restore the original vegetation and carry out earthwork activities and infrastructure construction It is a method of transplanting and paving for projects that need to protect the physical objects, environment greening, etc. Background technique [0002] In desert arid and semi-arid areas, vegetation plays an extremely importa...

Problems solved by technology

Due to climate characteristics such as drought, large atmospheric evaporation, and strong winds in the deserts of Xinjiang or Northwest China, the self-recovery ability of the environment is extremely low, and the harsh living environment conditions make the material cycle and energy conversion process in the ecosystem slow. Long-term The dryness and short growing seasons in China make the recovery period very long once the vegetation is destroyed, which easily causes grassland desertification and soil erosion, which invisibly causes waste of resources and damages the environment
