The invention provides a novel method for winter
bud grafting of young and strong mulberry with a grafted portion imitating original
ecology, and belongs to the technical field of agricultural mulberry cultivation. The method is characterized in that a traditional winter
bark cutting bud grafting method is changed, wherein according to the traditional method, 2-3 buds are grafted in different directions on a horizontal height on the upper portion of a young mulberry
trunk or one
bud is grafted on each
branch 3.3-6.6cm above the root of one
branch of the young mulberry or roots of two or three branches of a strong mulberry; according to the novel method, the grafted portion is selected by imitating the original
ecology position of a mulberry bud, the distance between an upper grafted bud and a lower grafted bud is 7cm, 3-4 buds are grafted on each
plant in different positions from the upper portion of the
trunk, or 2-3 buds are grafted on the periphery in different positions from the upper portion of each complete
branch, the spreading range of the branches is large after the buds survive, the positions are good, distribution is uniform, and directions are reasonable. Compared with the traditional
grafting method, the tree crown area in the same year is increased by 173.9%, the yield of mulberry leaves is increased by 45.6-98.9%, shaping production time is shortened by a year, and the method can be widely applied to improvement of young and strong trees of various mulberry fields, four-edge mulberries, large-
ridge mulberries and
coriaria sinia except non-
trunk mulberries.
