High-efficiency construction method of cutting orchard of Carya illinoensis

The invention belongs to the technical field of afforestation, and discloses a high-efficiency construction method of a cutting orchard of Carya illinoensis. The method includes two stages: rootstockcultivation and grafting survival, and according to the high-efficiency construction technique of the cutting orchard of Carya illinoensis, direct grafting to rootstocks is conducted through rootstockcultivation and secondary grafting; high scion grafting is adopted in spring, the height of a cut trunk is 40-60 cm, and two buds are grafted to each plant symmetrically; in early and middle August of the year, square bud grafting is conducted on plants which are grafted in spring but do not survive. Through rootstock cultivation free of a seedling recovering period, rapid growth of seedlings canbe ensured, a remarkable afforestation effect is achieved, the period from the seedlings to a rapid growth period of a forest is reduced into 4 years, and two years are saved when the method is compared with an original method
