Method for raising summer-time transplanting survival rate of osmanthus fragrans 'Rixianggui'

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of seedling transfer, in particular to a method for improving the survival rate of Japanese osmanthus during summer transfer. Background technique [0002] Rixianggui is an evergreen shrub of the family Oleaceae. It is a horticultural variety of osmanthus. It was jointly identified as a stable variant of osmanthus by experts from the Osmanthus branch of the China Flower Association, and it was named Rixianggui. It has a plump tree shape, many branches, and can bloom all year round. The flowers are white at first and then golden yellow. In actual gardening projects, most seedlings are planted in off-season periods. In order to improve the survival rate of Japanese osmanthus transplanting, a large number of pruning methods are often used, but the short-term landscape effect of the seedlings is not good, affecting the appearance. Therefore, research on the protection technology in the process of transplanting ...
