Embodiment 1

[0022] 1. Growth environment

[0023] The production environment is located in Minqin County, Gansu Province. Minqin County is located in the northwest of Gansu Province, the northeast of the Hexi Corridor, the lower reaches of the Shiyang River Basin, surrounded by the Tengger and Badain Jaran deserts on the east, west and north sides. Minqin County belongs to the temperate continental arid climate zone, and the continental desert climate features are very obvious, with windy sand, little rain, cold winter and hot summer, sufficient light, large temperature difference between day and night, annual average precipitation of 110 mm, evaporation as high as 2644 mm, day and night The temperature difference is 25.2°C, the annual average temperature is 7.8°C, the sunshine hours are 3073.5 hours, the frost-free period is 162 days, and the land is mostly sandy soil.

Abstract

The invention discloses an ecological remediation method, relating to raising seedling transplanting of an ecological remediation plant, and belonging to the technical field of plant cultivation. Vegetation is planted in a desert marginal area mixed with desert alga and bacillus, thereby playing wind prevention and sand fixation effects; with the adoption of the method, the land is protected compared with a single plant method, thereby playing the wind prevention and sand fixation effects; as seeds are strong in fertility, strong in adaptability and strong in stress resistance, the use amount of pesticides and fertilizers is reduced, and the liquorice quality is improved; and the algae and microorganism are united to be used, the mutual effect of the algae and the microorganism promotes growth, therefore, with the adoption of the method, a sand stabilizing structure is formed in desert soil rapidly and permanently compared with a former ecological restoration technology in the prior art, and the benefit of ecological environment is generated.

Description

technical field [0001] The invention relates to seedling raising and transplanting of ecological restoration type plants, which belongs to the technical field of plant cultivation, in particular to an ecological restoration method. Background technique [0002] The 21st century is the century of repairing the earth. Due to economic development in the industrial revolution era, the earth's ecosystem has been severely damaged and the earth's ecosystem is in a state of degradation. In this context, the application prospect of the discipline of ecological restoration is growing. [0003] Minqin, Gansu, my country is cold in winter and hot in summer, with lots of wind and sand and little rainfall. It is a typical temperate continental monsoon climate. The vegetation coverage rate decreases and the surface evaporation increases to form a saline-alkali land, so it belongs to a damaged ecosystem. Research on the degradation and ecological restoration of damaged ecosystems has attra...
