In recent years, Liu Yongkang, an agronomist at the Wen County Institute of Agricultural Sciences in Henan Province, has devoted himself to research and breeding on shoot-tip virus elimination in the Chinese medicinal herb Rehmannia glutinosa, actively carrying out research and promotion of new variety selection, purification and rejuvenation, updated cultivation techniques, and new agricultural technologies for Rehmannia glutinosa, performing shoot-tip virus elimination on Rehmannia glutinosa, breeding virus-free seedlings, and establishing a three-tier breeding system for virus-free Rehmannia glutinosa planting material.
Driven by Liu Yongkang, Wen County has built and formed a large-scale breeding base for virus-free Rehmannia glutinosa planting material, and has innovated its agricultural technology extension service methods. Because virus-free Rehmannia glutinosa has strong disease resistance, vigorous growth and high yield, it is widely welcomed by farmers. Photo by Xinhua News Agency reporter Zhu Xiang
