The present invention relates to a method for raising a summer-time
transplanting survival rate of
osmanthus fragrans 'Rixianggui'. The method comprises a first step of
transplanting season selection: selecting August at summer, and the temperature being 29-36 DEG C; a second step of soil ball digging: the size of a soil ball being 1 / 3-1 / 2 of a natural crown breadth, vertically ditching around a crown by using the
tree trunk as the center; a third step of
transpiration retardant spraying: concentration of a
transpiration retardant being prepared to be 40 mg / L, spraying the
transpiration retardant onto leaves, the
tree trunk and the soil ball, water not dropping off the leaves, the tree trunks and the soil ball, and the transpiration retardant being absorbed after8-10 minutes; a fourth step of hoisting and transporting; a fifth step of
pruning and leave picking:
pruning away
insect-plague branches and removing 1 / 3 of the leaves; a sixth step of digging for plantation: a
plant pit being sized as that a
diameter thereof is 40 cm larger than that of the soil ball and the depth is 20 cm larger than that of the soil ball; spraying a 80 mg / L ABT NO.3 rooting
powder around the soil ball of a root part for 4-5 times by using a
sprayer before plantation, backfilling the soil, and tamping the soil layer by layer, thus to fully bury the soil ball under the ground; a seventh step of supporting; and an eighth step of watering: immediately watering the
plant after plantation, and watering the
plant for the second time three days after the plantation and for the third time six days after the plantation. The method provided by the present invention is simple to operate, the
survival rate can reach 90%, and enterprise cost can be saved.
