It is necessary to wipe the buds as soon as possible, which is beneficial to the growth and development of seedlings. When the seedling height is 20 cm, different branches are reserved according to different planting densities. If the plant spacing is 0.5m, only 1 branch is left; Moreover, the plant spacing is 0.8 meters, and branches can be left in the opposite direction, ***2 branches.
When the new tip is 30 cm long, it should be tied; And timely wipe off the auxiliary tip on the new tip below 30 cm from the ground. If Kyoho grapes extend forward with strong shoots, when the new shoots grow to 30 ~ 40 cm, they should be tied and picked.
It is necessary to remove the sprouting secondary buds in the axils of leaves at any time. When the new shoots grow to about 2.5 meters, coring is carried out, and 2-3 secondary shoots are left at the top, and 2 leaves are left at each secondary shoot for repeated coring, so as to promote the nutrient accumulation of the main shoots, the maturity of branches and the formation of flower buds. After defoliation in autumn, each plant leaves 1 main vine with a root length of about 1.5m (about 20 knots).
