Apple seedling cultivation method capable of being suitable for southern Hunan and sub-southern Hunan

Abstract

The invention discloses an apple seedling cultivation method capable of being suitable for southern Hunan and sub-southern Hunan. The method includes the following steps that a, branches of three apple trees of red Fuji spur, Gala and Chenyang are utilized to be grafted in high positions of wild sweet tea tree rootstock in the South; when apple grafted seedlings grow to 70cm, sweet tea tree branches on the rootstock are pruned so as to facilitate growth of the apple grafted seedlings; b. southern wild sweet tea tree branches are grafted to southern wild malus baccata tree rootstock in a T-shaped mode in autumn 8-9 month, and the top of the malus baccata rootstock is pruned before 20 days of sprouting of the sweet tea tree branches in the first ten-day period of the march of the year ensuing; c. branch sprouts of red Fuji spur after fruits are hung are grafted to the sweet tea branches which grow tall after grafting through the step b by means of the step a in autumn 8-9 month; d. the branch sprouts of the red Fuji spur through the step c are utilized to be grafted to malus robusta rootstock until the autumn 8-9 month of the next year after the year ensuing after grafting in the step c.

Description

technical field [0001] The invention relates to a method for planting apples, in particular to a method for cultivating apple saplings suitable for southern Shonan and regions south of it. Background technique [0002] Apple is a kind of cold-resistant and high-temperature-resistant plant. It is suitable for regions with dry climate in summer and sufficient sunlight, cold temperature in winter and large temperature difference between day and night, so it grows in the north. In the south, especially in the southern part of Shonan, the temperature is high, the humidity is high, the temperature difference between day and night is small, and the rainy season is long. The current apple trees are not suitable for planting in the south. After many years of experiments, apple saplings that can be planted in the north cannot grow and bear fruit normally in the south; even if apple seeds planted in the north are cultivated in the south according to conventional methods, apple saplings...
