Pruning method for kiwifruit in elevated wide-spacing close-planting cultivation

Abstract

The invention discloses a pruning method for kiwifruit in elevated wide-spacing close-planting cultivation, which includes the steps: preparing a land and ridging; planting single kiwifruit seedlings at intervals of one meter; setting uprights on each ridge at intervals of 4 meters, and setting up a grid shed with steel wire ropes; performing pinching when each kiwifruit seedling grows 2.0-2.5m long; after the top of each seedling sprouts, reversing two buds and removing other buds; allowing the two buds to grow in opposite directions perpendicular to the ridges along the steel wire ropes andgrow into main vines; dividing adjacent kiwifruit plants on the ridges into near plants and far pants, and pruning the near plants and the far plants respectively; when the main vine of each near plant grows about 3.0m long, controlling the main vine not to grow forward, and allowing fruiting branches to grow on the main vine at intervals of 30-40cm; when the main vine of each far plant grows about 4m long, controlling the main vine not to grow forward, and removing all growing branch buds in an area 2.5m from the end of each branch on the corresponding ridge to the main vine; and allowing fruiting branches to grow on the main vine from the 2.5m position to the tail end of the main vine. By the method, reasonable distribution of kiwifruit vines can be promoted, and good ventilation and sunlight are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of fruit tree cultivation, and particularly relates to a method for cultivating and pruning kiwifruit with densely planted kiwifruit at elevated and wide distances, which can promote the rational distribution of kiwifruit branches and tendrils, ensure good ventilation and light, and is especially suitable for leisure and sightseeing orchards in modern cities. Background technique [0002] Kiwi fruit is native to my country, and because of its particularly rich vitamin C content in fresh fruit, it has become popular all over the world and has become a new type of fruit tree. In addition to the content of vitamin C in the fruit, which is several to ten times higher than that of apples and sweet oranges, it also contains vitamin P (that is, rutin) and proteolytic enzymes, which can lower blood pressure and help digestion. It is a health and nutritional food . In terms of medicinal value, according to modern me...

AI Technical Summary

Problems solved by technology

[0005] In the prior art, the same pruning method is adopted for all kiwifruit plants. Although the problem of excessively dense kiwifruit branches and tendrils can be solved to a certain extent, after the branches and tendrils of adjacent kiwifruit plants grow to a certain length, crossing of branches and tendrils is still easy to occur. The overlapping phenomenon not only affects the normal growth and results of kiwifruit, but also brings a lot of inconvenience to field management
