Transplanting: transplanting grafted seedlings with soil from early September to late October, with row spacing of 1.8m× 3m and per mu 123 plants; When the transplanting depth is 45cm, when the backfill soil reaches the level of the table top, sufficient root setting water is poured, and then fine soil is filled until the mound is slightly higher than the table top15 cm; /kloc-after 0/5 days, the diseased plants and dead seedlings should be removed in time, and the seedlings should be replenished in time.
Fertilization: apply 2.5 tons of mixed fertilizer per mu three times a year, in February-March, June-July,10/65438+10 respectively; Spraying selenium-enriched foliar fertilizer at the late stage of fruit expansion, with the dosage of 28 kg per mu.

breeding method
In the middle and late February, the seeds of Fructus Aurantii Immaturus with developed roots were selected to raise seedlings in a nutrition bowl. In mid-September, strong semi-lignified branches with high blood orange yield were selected as scions, and two inclined planes were cut with a knife at the lower part of axillary buds, with the upper part flush and 4 cm long, and two axillary buds were reserved.
Cut the seedlings from the ground 5 cm away from the ground, cut the rootstock in half, and the incision length is 0.8- 1.5 cm. The scion was inserted into the rootstock, aligned with the cambium, covered with plaster, mixed with indoleacetic acid and 6- glycosylaminopurine according to the mass ratio of 1:20, diluted 2000 times, and sprayed on the grafting site.
The nutrition bowl is a plastic container with a height of 1 1 cm, an upper opening diameter of 12 cm and a bottom diameter of 9 cm. Carbonized rice husk, decomposed farmyard manure, earthworm soil, pond sludge and garlic powder are mixed in a volume ratio of 2: 4: 3: 5:1,disinfected and put into a plastic container.
