The invention belongs to the technical field of grape plants, and particularly relates to a managing method for Kyoho grape plants. The managing method includes the following steps: after planted grape plants germinate, in spring, the grapes
shoot, double shoots and budlets are early removed, strong shoots are reserved, and besides, part of
inflorescence is properly thinned; in winter, long tips are trimmed; in summer, the
inflorescence is timely thinned, and ear tips are timely pinched off, so that the
nutrition supply is dispersed; after the grapes are harvested, clumpy branches and tendrils are trimmed along with leaves; and during the management period, , 3 kilograms of superior barnyard
manure is applied for each
kilogram of fruits; after young leaves develop, before flowers bloom and after the flowers fall, 0.2% of
urea and 0.2 of
potassium dihydrogen
phosphate are respectively sprayed on the surfaces of the leaves once; in spring, after the grape plants are excavated,
sprouting watering is performed once, and after the flowers falls, fruits enter a rapid expanding stage; watering needs to be performed once every 10 days, and after the fruit grains start coloring, watering is stopped. The grape plants planted with the management method have close clusters, and neat and consistently mature fruit grains; the special
flavor and the color of
berry can be improved, the
nutrition consumption is reduced, the strong fruits and mother vines are cultivated, and besides, the
air humidity under frames can further be reduced, so that the
plant diseases are avoided, the
sugar degree of the fruits can be increased, and the coloring and the maturity of the branches and tendrils are promoted.
