Each node is about 1.5 ~ 6cm long, leaving 2 ~ 3 buds. Remove the lower part or half of the leaves of cuttings, generally cover the greenhouse and seedbed with plastic film or field, and insert them in the seedbed with fine sand as the substrate. The cutting depth is 5 ~ 6 cm, and the plant spacing is 5 ~ 5~5cm. The cuttings are kept moist, shaded for the first 5 days under field conditions, and can survive and take root after 1 month.
Grafting and seedling raising: branch grafting or bud grafting can be carried out in July and August. Selecting the branches of excellent plants as scions and the seedlings of wild Zizyphus jujuba as rootstocks can grow new seedlings that year.
Korean Actinidia arguta mainly adopts split grafting or green branch grafting before or after bleeding point. Hedgehog and shed are mainly used for cultivation, but considering that hedge cultivation is easy to manage, the row spacing and plant spacing are 2 ~ 3 mxl ~ 2 m, which likes rocky soil growth, water but not waterlogging. Pruning advocates heavy pruning, pruning three times a year: first, pruning in winter, second, pruning long branches, and third, pruning medium and long branches after flowering and fruiting, so that the fruiting branches are lightly pruned, mainly thinning. Garden construction and planting: select semi-sunny slopes with loose soil, good drainage, high humus content and slightly acidic or neutral soil.
When building a garden on a hillside with a semi-shady slope, avoid choosing clay land. Before planting, it is necessary to prepare soil with a depth of 25-30cm, apply sufficient base fertilizer, and plant in the south of the east-west hedge frame, with the plant spacing of 2.5×1.5m. When planting, first dig a planting pit with a width of 30cm and a depth of 35cm, then return a small amount of soil, put the seedlings in the shape of "steamed bread" with their feet, stretch the roots, and return the soil to the seedlings. Because kiwifruit is mostly male and female, attention should be paid to the configuration of pollination trees when planting. The ratio of male and female plants is 8∶ 1, which can be planted in spring and autumn.
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.
