The invention relates to the technical field of grape
seedling cultivation, in particular to a grape
seedling cultivating method. The grape
seedling cultivating method includes the following steps that firstly, in early April, a grape seedling is
cut into a grape
shoot for
cutting, wherein the length of the grape
shoot for
cutting ranges from 0.5 m to 0.8 m, and 4 to 6
bud eyes are reserved in the grape
shoot for
cutting, and then the grape shoot for cutting is disinfected through an
ultraviolet sterilization lamp, wherein
ultraviolet disinfection time ranges from 15 min to 30 min; secondly, a seedling bag filled with
nutrient soil is placed on a
seedbed, and the
nutrient soil is completely irrigated through drop
irrigation, wherein
irrigation time ranges from 1 hour to 4 hours, the grape shoot for cutting is inserted into the
nutrient soil after
irrigation, and the
bud eyes of the grape shoot for cutting are exposed out of the nutrient soil. According to the grape seedling cultivating method, seedling cultivation is conducted again in the seedling cultivation bag,
nutrition supplied to the grape shoot for cutting is more sufficient, the grape shoot for cutting grows better, the excellent characters of a grape stock
plant can be kept, the seedling
reproduction number is increased by 50% in average compared with that of a root burying seedling cultivating method, and the yield obtained after fruiting is increased by 40% in average.
