A kind of intensive and high-efficiency cultivation method of apple tree dwarf stock

Abstract

The invention discloses an intensive high-efficiency dwarf stock cultivation method for apple trees, and provides a garden building method including nursery stock selection, wide-row close planting, middle-stock burying and planting, trellis cultivation, shaping and pruning and the like. For different climatic conditions of different areas, different dwarf stocks are provided, and it is important to select suitable dwarf stocks in each area. The lengths of middle stocks of selected nursery stocks are kept uniform during garden building, the middle stocks are buried with soil during planting until the top ends of the middle stocks are exposed out of the ground by 1-10cm, and the burying depths of the middle stocks are uniform. The burying depths of the dwarf middle stocks relate closely to the sizes of crowns, and particularly, are of a great significance in building of gardens with high uniformity in crown size. The intensive high-efficiency dwarf stock cultivation method is suitable for the situation of China, and the built apple gardens have the advantages of low investment, early fruiting, high yield, high benefit and convenience in management.

Description

technical field [0001] The invention belongs to the technical field of apple cultivation, and relates to an intensive and high-efficiency cultivation method for apple tree short stock. Background technique [0002] my country is the world's largest producer of apples, and its cultivated area and output account for more than 1 / 2 of the world's total, accounting for 20% and 30% of my country's fruit area and output, respectively.
