Recently, the reporter walked into the greenhouse of potato original seed mist cultivation by Li Jinfu in Dingxi City, Gansu Province. The mist cultivation box, the automatic control spray system, and the potato root system hanging in the air came into view.
Li Jinfu introduced that relying on the atomized nutrient solution, potato roots can grow completely in the air, which is easier to automate control and three-dimensional cultivation, improve the utilization of greenhouse space, and reduce the occurrence of potato original seed diseases.
Over the years, Li Jinfu has continuously explored soilless cultivation techniques to improve the quality of the original potato seeds. The high-quality minitubers have attracted waves of buyers.
"In recent years, due to the improvement of quality, a steady stream of orders, limited production scale, too many orders, it is also a sweet trouble." Li Jinfu said.
