The invention discloses a method for rapidly raising high-quality 'three-current' (raising stocks,
grafting and moving seedlings out of nurseries in the current year) well-bred seedlings of
Carya illinoensis. The method disclosed by the invention comprises the following steps of: quickly breaking the
dormancy of seeds through soaking the seeds into
gibberellin, and carrying out seed stratification in a
hotbed three months ahead of schedule;
cutting the
taproot growing points of sprout-stocks so as to carry out sprout-stock root breaking; carrying out container
seedling-raising by using customized containers and a self-made matrix, placing the customized containers in a
greenhouse and keeping for half a month, and after the customized containers are moved out of the
greenhouse, completely burying the containers into soil; during the fast growing period of stock seedlings, daubing a
gibberellin solution on the basal parts of stems, so that the ground-
diameter thickening is effectively promoted, and a large number of high-quality stock seedlings meeting the requirements of
grafting are raised in early July; and about 10-15 days after the
grafting is successful,
cutting out stock parts 1cm above graft buds, daubing
gibberellin on the graft buds, and strengthening
nutrient and water management, so that the graft buds grow to branches of 30-40 cm, and the heights of grafted seedlings in the current year meet the out-of-nursery standards of 50-60 cm, thereby raising a large number of healthily-growing 'three-current' well-bred seedlings of
Carya illinoensis. Compared with the traditional
seedling raising method, two years are shortened.
