Tree top grafting and head changing cultivation method

Abstract

The invention relates to a tree top grafting and head changing cultivation method. The tree top grafting and head changing cultivation method comprises the following steps: (1) ridging and furrowing on cultivated land, and excavating tree pits on crested land; (2) selecting rootstocks; (3) in the last ten days of October, carrying out field planting on the rootstocks; (4) grafting, namely after rootstock transplant seedlings survive, grafting by adopting a cut-grafting method; (5) carrying out field management, namely after grafting, frequently removing buds and unwanted sprouts, and ventilating and putting in bags in scion survival and growth initial stages; and (6) typing a mature tree. The tree top grafting and head changing cultivation method has the advantages that a top grafting andhead changing grafting technology is adopted for enabling ulmus laciniata, common elm, yellow elm, crown elm, red elm, fraxinus autumn purple and acer negundo to be rapidly molded, planting cost and afforestation cost are reduced, and multiple styles can be made, so that ornamental value of elms is fully shown, tree specific properties are stabilized, new tree varieties are found, and colors of trees are enriched; and the cultivation method is simple, and the survival rate is high and can reach 90% or above.

Description

technical field [0001] The invention belongs to the technical field of improvement and optimization of garden plant varieties, and in particular relates to a method for cultivating trees with high joints and heads. Background technique [0002] Split-leaf elm, round crown elm, golden-leaf elm, red elm, golden-leaf white wax, purple-leaf white wax, golden-leaf compound leaf maple and other trees have bright colors and good visual effects, and their ornamental value is high. In landscaping projects, as one of the main materials of greening trees, it is widely used in various environments and forms of landscaping such as roads, courtyards, parks, and community greening. However, these trees grow slowly, are not easy to be quickly formed, have a small amount in the market, and are scarce in resources; and the planting cost is high, and they are high-priced ornamental trees. Moreover, through conventional sowing and propagation, the traits cannot be stabilized, and the phenomeno...
