Pruning: The branches and buds of Actinidia arguta grow vigorously, and pruning is very important to maintain its yield, longevity and individual cold resistance. Hedge frame and shed frame are mainly used for shaping, planting 1 ~ 2 years to cultivate 3 main vines, and cultivating fruiting branches in the third year. Through pruning, the bearing mother branches and their bearing branches on the lateral vines are evenly distributed, and the vines can be full of trees after 3 ~ 4 years, and pruning can be carried out in summer and late autumn.
Irrigation and fertilization: Actinidia arguta likes warm and humid environment. If it is dry, it will stop growing. Pay attention to irrigation all year round. The soil can neither be dry nor accumulate water, so it can be irrigated in combination with fertilization. Irrigation with antifreeze water before winter and spring irrigation after thawing to meet the needs of its growth and fruiting. Fertilization should be carried out frequently, in small quantities and shallowly. Base fertilizer can be applied in furrow in spring and autumn, and it can be applied twice a year/kloc-0. Topdressing 1 time, topdressing when young trees germinate and new shoots begin to grow, topdressing effective nitrogen fertilizer urea; The second time in late July, topdressing phosphorus and potassium fertilizer (the mixture of diammonium and 40% potassium sulfate is 2∶ 1), or topdressing human feces, promotes the branches and vines to fully mature and fill the bud eyes, which is beneficial to fruit development.
Jungle transformation: Actinidia arguta grows by attaching to other trees under natural conditions, so it is easy to be crushed. First of all, some upper trees and shrubs that are too dense to be used for climbing Actinidia arguta should be cut down to keep the horizontal canopy density at 0.3 ~ 0.4.
