Ultrahigh-density apple cultivation method

The invention discloses an ultrahigh-density apple cultivation method. According to the method, selected seedlings are short-branch dwarfing rootstocks; field planting parameters are as follows: wide-row field planting is performed, the row spacing is larger than the plant spacing, the row spacing is 3.5-4.0 m, and the plant spacing is 0.3-0.6 m; the length of overground rootstock between the plants is 10-15 cm; the trunk fixing height is 1.5-1.7 m; and after fruiting, 20-30 fruits are reserved for each plant. Wire drawing and stand erecting are not needed in apple close planting, and the problems that in the prior art, an apple dwarfing rootstock cultivation management technology is difficult to master, the production cost is high, and the early-stage yield is low are solved; and the method adopts wide-row cotton field type management, and is easy to master, extremely labor-saving and high in return benefit. 本发明公开了一种超高密度苹果栽培方法，其选用的苗木为短枝矮化砧木；定植参数如下：进行宽行定植，行距大于株距，行距3.5～4.0m，株距0.3～0.6m；株间地上砧木长度为10～15cm；定干高度为1.5
