Hongjiang orange seedling summer grafting cultivation method

The invention belongs to the technical field of grafting and particularly discloses a Hongjiang orange seedling summer grafting cultivation method. A Hongjiang orange scion and a stock are grafted indoors and moved to a prearranged greenhouse to be planted, the greenhouse is sequentially covered with an insect-proof net, a waterproof thin film and a sunshade net from inside to outside, a transplanted grafted seedling is watered with sufficient rooting water, and then fertilizer and water management and disease, pest and weed management are conducted. A rise grafting method is adopted, in other words, the qualified and healthy stock is selected for seedling grafting in a laboratory, meanwhile, the facility greenhouse is utilized, the waterproof, sun protection, windproof and moisturizing purposes are achieved, and the survival rate of the seedling is guaranteed. According to the technology, a branch fully growing in a parent material orchard in summer is fully used as the scion, and the propagation coefficient of the seedling is increased.
