The invention discloses a citrus
seedling breeding method with the advantages of convenient
transplanting, high
transplanting survival rate, no rejuvenation period after
transplanting, and greatly shortened citrus growth period. The method comprises the steps of a seeding-raising step, a
grafting step, a field management step, and a
seedling out-planting step. The seeding-raising step comprises
rootstock seedling cultivation and scion-picking female parent tree cultivation. The
rootstock seedling cultivation step comprises
seed treatment,
sowing, and transplanting cultivation. The
sowing step comprises
nutrient soil preparation,
seedbed sowing, and
seedbed management. In the transplanting cultivation step,
rootstock seedlings with heights higher than 15cm are directly transplanted into seedling-raising containers with
nutrient soil. In the scion-picking female parent tree cultivation step, detoxified Yongchun mandarin seedlings are field-planted in a mesh room, and scions are
cut in the second year after field planting. In the
grafting step, a scion is grafted on a transplanted rootstock seedling with
trunk height higher than 35cm and with a
trunk diameter of 0.6-0.8cm at a place with a distance of 10cm from the
soil surface. The
grafting place is on the rootstock seedling with more than 10cm from a root collar.
Grafting tools and personnel should be disinfected when grafting is carried out.
