The Stone Picker is hailed as the "Wonder Tool" for High Plateau Pioneering. With its complex terrain, low-quality arable land, and abundant sandy and rocky areas, the machine can automatically identify stones with diameters ranging from 30 to 70 centimeters and dig stones buried up to 40 centimeters deep in the soil, significantly reducing the labor required for manual land clearing and enhancing stone collection efficiency. In Litang, the Stone Picker also serves as a technology export to other counties in Ganzi Prefecture, as well as to cities like Guangzhou and Chongqing.

Efficiency Comparison: Manually picking stones requires 10 workers to cover half a cubic meter in one hour, limited to the topsoil layer; while the "Iron Bull" stone picker can cover 10 acres in an hour, collecting nearly four cubic meters per acre, which is 100 times more efficient than manual labor, and can reach stones buried 40 centimeters underground.

Comparison of Results: Previously, the land was full of stones, and the white radishes grew into crooked ones. Due to their poor appearance, the crooked radishes could not be sold, and were sold at a market price of 30 cents per pound. After removing the stones from the farmland and growing straight radishes according to market requirements, they were sourced directly by Hema, averaging 2 yuan per pound, a 600% increase in price. In 2020, the output value of Liangtang radishes reached 50 million yuan.
