AI Technical Summary

Technical Problem

Existing technologies for the rapid establishment of pioneer vegetation in high-salt desert areas suffer from low seed germination and seedling survival rates, severe impact from high salt concentration osmotic stress and ion toxicity, long growth cycles, huge water consumption, and unstable effects. Furthermore, the lack of effective regulation of micro-regional salinity differences leads to slow vegetation establishment, low coverage, and uneven distribution.

Method used

By constructing a salt gradient regulation system in high-salt desert areas, including excavating trenches, laying biochar isolation layers and mixed substrate layers, and installing microporous drip irrigation pipes, combined with a water regulation system and automatic control unit, precise sowing and leaching programs are implemented to construct a three-dimensional tree-shrub-grass community structure. Germination-promoting fungicides and mixed seeds are used to optimize water and salt management.

Benefits of technology

It can effectively regulate the salinity gradient, improve seed germination rate and seedling survival rate, optimize water use, reduce freshwater consumption, promote rapid vegetation establishment and healthy growth, enhance the resilience of the ecosystem, realize the rapid establishment of multi-level community structure, improve soil fertility and microclimate, and enhance the stability of the ecosystem.

Abstract

The invention discloses a high-salinity desert region pioneer vegetation rapid planting method based on salinity gradient regulation and control, and relates to the technical field of vegetation planting. The method can effectively regulate and control gradient distribution of salinity in the high-salinity desert region, reduce salt stress of a root zone, improve the seed germination rate and the seedling survival rate of pioneer vegetation, effectively inhibit surface salinity accumulation and optimize moisture distribution, thereby promoting rapid field planting and healthy growth of vegetation; by constructing a stable salinity gradient and moisture regulation and control system, through a micro-irrigation system and a mixed matrix layer, the moisture utilization efficiency is optimized, the fresh water consumption is reduced, the vegetation coverage is improved, the soil erosion risk can be reduced, the stress resistance of an ecological system is enhanced, and the vegetation coverage is rapidly improved in a short time; finally, the desert region is promoted to succession towards a multi-layer and stable arbor-shrub-grass community structure, the soil fertility and the microclimate environment are improved, the stability and the wind erosion resistance of an ecological system are enhanced, and reliable technical support is provided for sustainable ecological restoration.
