Citrus seedling grafting method

Abstract

The invention discloses a citrus seedling grafting method. A fructus aurantii seedling sown on a seedbed last year is selected as a rootstock, a scion is treated with hot and humid air on the day of grafting, the hot and humid air contains tetracycline hydrochloride and 2,4-D, the scion which is cut is quickly inserted into a rootstock grafting union during the seedling grafting process, a grafting film is then used to seal the grafting union, a novel lipid membrane diluent is used to be sprayed on the coating part of the grafting film, a multi-functional tree grafting device is then used forfixing, a knife is used to cut a small opening on the grafting film in a covered surface of the sealed rubber, a plant growth regulator solution is then sprayed, the grafted citrus seedling is cultivated under suitable light and humidity conditions after the grafting, during the first 15 days after grafting, pesticide spraying on the grafting film in a covered surface of the sealed rubber is carried out for every 5 days and every 10 days, and the healing condition of the grafting union is checked for every other week. A disinfection function is achieved, formation of a scion separation layer is also prevented, infection of pathogens is isolated, and the survival rate of grafting is improved.
