The invention discloses a quick cultivation method for macadimia nut seedlings. The method comprises the steps that a
branch, which grows in the current year, has at least three rings of leaves and is 20 cm or above long, of a macadimia nut tree is selected, the
branch to be sheared is scratched at the beginning of March, the base of the
branch is girdled in the middle ten days of March, the branch is sheared off perpendicularly from the base in the first or middle ten days of April, a
cut is made round, a protective agent is smeared at the round
cut, and linen
fiber cloth is used for winding around the branch from the base
cut to wrap the branch and then is tied tightly; before
cutting, three rings of leaves on the upper portion of the branch are left, remaining leaves are sheared away, a bevel cut is sheared from the position 3 cm away from the base towards the base, the branch is sheared to be 16-18 cm long, a rooting
promoter is sprayed exactly to the bevel cut, and a
cutting branch is obtained for use; the part 8 cm below the base of the
cutting branch is inserted in a sand
bed matrix until the cutting branch is moved out of a garden for planting. Through the quick cultivation method, the cutting rooting rate is up to 97.2%, and the seedlings can be moved out of the garden within three and a half months to the shortest extent.
