The invention discloses a novel aging mulberry rejuvenation and improvement method capable of allowing the yield to be increased in the same year after the half-year
grafting time, and belongs to the technical field of gardening mulberry cultivation. The method is characterized in that ear buds are inserted in the same direction; winter
bud grafting and spring
bud grafting are used simultaneously; and sawed
pile multi-
bud grafting is performed. An improved spring sawed
pile bud grafting (ear bud inserting in the same direction and multi-bud grafting) is applied by the method, and a winter
skin cutting and bud
grafting method is successfully applied to winter and early spring sawed
pile bud grafting by using a method of skiving a rough
bark of a stock, so that the grafting time is prolonged to half a year during which ear strips are not required to be stored; the number of grafted ear buds of each mulberry is increased from 2-3 to 5-10 by adopting the multi-bud grafting, so that the yield can be increased by 50-200% in the same grafting year, and mulberry tree type cultivation can be accomplished on time; and a grafting body and a stock tree body can be healed tightly and firmly by adopting the ear bud inserting in the same direction, so that the long-term
survival rate of the graft body is high. According to the method, the ear bud
survival rate is not less than 97%; the mulberry
survival rate is not less than 99%; and the method can be widely applied to renewal rejuvenation and variety improvement of aging trees of various mulberry fields, four-edge mulberries, daxing mulberries,
coriaria sinia and arbor mulberries.
