AI Technical Summary

Technical Problem

The existing method of planting Caragana microphylla in pits results in low survival rates due to rapid water evaporation in the Hunshandake Sandy Land, and is also time-consuming and labor-intensive.

Method used

The method involves using a grid-like low-rise sand barrier, planting tools, and specific planting techniques, including selecting fully lignified bare-root seedlings, cutting off the top and roots, dipping the roots in mud slurry, and temporary planting. The seedlings are then directly planted into a stable, moist sandy soil layer using planting tools to ensure that the roots are deeply embedded and in close contact with the soil, thus avoiding water evaporation and mechanical damage.

Benefits of technology

It significantly improved the survival rate of Caragana microphylla, reduced water evaporation and human and material input, formed an effective sand fixation and ecological protection system, and is suitable for large-scale sand control and desertification prevention projects.
