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.
