The invention provides an operation method for
transplanting wild big trees, and relates to a method for
transplanting wild big trees. The method comprises the following: a step of
cutting off lateral roots, which is to take a
trunk as a center and
ditch taking the
radius which is 3 to 4 times of the
diameter of breast height, and a soil ball formed by ditching is in a reverse trapezoidal shape with big top and small bottom; a step of promoting new roots, which is to erect a row of wood boards serially connected by use of linen threads along a middle boundary of
ditch width, spray root cuts with root power water on the side near the soil ball, spray the soil ball with
root rot liquid
medicine, backfill a
mixed matrix of
moss and
river sand, backfill and tamp soil in
layers on the other side; a step of
cutting off a
taproot, which is to
ditch along the outer side of the wood boards after absorption roots are formed on the root cuts in next year,
cut off a thick root and form a soil ball which is surrounded by the wood boards and is in a reverse circular truncated cone; a step of bunching the soil ball, which is to use
straw ropes to bunch the basal part of a big tree and then nail guard plates; a step of lifting and unloading the big tree into a planting hole dug in advance after lifting and transporting the big tree to a destination; and a step of fixing and planting, which is to place the tree into the hole, remove the
straw ropes and wood board binding materials and fill the hole with soil. The method can ensure that the
survival rate of transplanted big trees is nearly 100 percent, thereby greatly improving environment
greening ratio.
