The invention provides a guava cutting seedling-raising method comprising the steps of A, cutting slip selection, B, cutting preparation, C, cutting, and D, cutting post treatment. According to the invention, half-lignified softwood branches are adopted as cutting slips. Compared with that adopting hardwood branches, a rooting rate is improved. Before cutting insertion, the lower ends of the cutting slips are soaked by a growth regulator. After the cutting slips are inserted into a seedbed, the growth regulator is added in the medium around the cutting slips. With the effects and influences of the two applications of the growth regulators on the lower ends of the cutting slips, the cutting slip activity and the rooting rate can be greatly improved. Water mist is sprayed intermittently to the cutting slips, such that humidity in the sunshade shed can be effectively maintained, and cutting slip rooting can be promoted. The seedbed is subjected to a heating treatment, such that the influence of diurnal temperature difference on the cutting slips can be prevented, and a normal cutting slip rooting environment is ensured. In summary, the cutting method provided by the invention has the advantages of simple steps, convenient management, short period, and high survival rate. With the method, a large amount of seedlings can be cultivated within a short period of time.
