In 2007, a new technology suitable for black land came into being in Lishu county, protective tillage technology. Straw covers the surface, tillage is reduced to a minimum and soil disturbance is minimized to ensure ample soil support.

"After years of covering it with straw, the black soil has reached 50-60 cm, and the root system of corn can be planted to 200 cm," Yang Qingkui, director of the Kangda Agricultural Machinery Farmers' Professional Cooperative in Lishu county, said. And now an ordinary cooperative member has an annual income of at least 100,000 yuan.
