Zhangwu Soil Improvement Demonstration Base in Liaoning is a demonstration base for the improvement and application of sand flm materials built by BGlin cooperation with the Sandy Land Research Institute of Liaoning Academy of Agricultural Sciences on desertified sandy land.

Focusing on improving the quality and effciency of sandy land agriculture, the base takes peanut as the core test crop and carries out field application experiments of sand film materials.
The results show that the sand film material can significantly improve the planting conditions of sandy land, achieving a per-unit-area peanut yield increase of 39.6% and a maximum per-plant yield increase of 82%. It provides a practical and replicable solution for ecological restoration and sustainable agricultural development of desertified land.
