The correspondent from the Academy of Forestry, Qinghai Academy of Forestry was informed that by the Qinghai Province, climatic conditions and technical limitations, grafted walnut seedling technology has not been a breakthrough, and to some extent, restricting the development of the industry of walnut in Qinghai Province. At the end of 2012 and early 2013, the Lincoln Institute sent scientific and technical personnel to visit the main walnut producing areas in Shaanxi, Liaoning and Xinjiang to study the technology of grafting walnut seedlings and the introduction of indoor hotbed grafting techniques. On March 21, 2013, double-tongue method was used to carry out the experiment of grafting and nursery of walnut seedlings in the greenhouse in April 15, 2013 on the basis of preliminary preparations such as constructing beds, laying hotlines, laying disinfection sawdust, installing automatic temperature control equipment, etc. Day (after grafting
