Embodiment 1

[0048] This example was carried out from 2015 to 2017, and a total of 700 plants were grafted. Green split-leaf elm, long-branch elm, yellow elm, round crown elm, black elm, yellow golden-leaf elm and red red elm were grafted with 100 plants each. The survival rate was 93%, 90%, 91%, 90%, 91%, 92%, 90% in turn, and the graft survival rate was 91%.

[0049] (1) The planting site is selected in a nursery with flat terrain and irrigation conditions. After the nursery is selected, the soil is first sprayed with herbicides and grass seed inhibitors, and then the soil is deeply plowed, rotary tilled, raked, disinfected, Insecticide treatment and other operations, ridges and furrows are made on the planting ground, the height of the ridge is 30cm, and the width of the furrow is 3m; tree pits are dug on the furrow land, the spacing between the tree pits is 2.5m, and the row spacing is 3m. The diameter of the rootstock soil ball is 30-50cm, and the depth of the tree pit is greater than...

Embodiment 2

[0068] This example was carried out from 2015 to 2017. A total of 500 plants were grafted. The grafted ones were yellow golden leaf white wax and red purple leaf white wax. Each grafted 250 plants. The survival rates were 92% and 92.8%, respectively. 92.4%.

[0069] (1) The planting site is selected in a nursery with flat terrain and irrigation conditions. After the nursery is selected, the soil is first sprayed with herbicides and grass seed inhibitors, and then the soil is deeply plowed, rotary tilled, raked, disinfected, Insecticide treatment and other operations, ridges and furrows are carried out on the planting ground, the height of the ridge is 30cm, and the width of the furrow is 3m; tree pits are dug on the furrow land, the spacing between the tree pits is 2m, the row spacing is 2m, and the diameter of the tree pits is larger than that of the rootstock The diameter of the soil ball is 30-50cm large, and the depth of the tree pit is greater than the 20-30cm of the orig...

Embodiment 3

[0088] This example was carried out from 2015 to 2017, and a total of 300 plants were grafted, and the grafted ones were yellow Acer aurantiaceae, and the grafting survival rate was 90.3%.

[0089] (1) The planting site is selected in a nursery with flat terrain and irrigation conditions. After the nursery is selected, the soil is first sprayed with herbicides and grass seed inhibitors, and then the soil is deeply plowed, rotary tilled, raked, disinfected, Insecticide treatment and other operations, ridges and furrows are carried out on the planting ground, the height of the ridge is 30cm, and the width of the furrow is 3m; tree pits are dug on the furrow land, the spacing between the trees is 1m, and the distance between rows is 1m. The diameter of the soil ball is 30-50cm large, and the depth of the tree pit is greater than the 20-30cm of the original soil ball diameter of the rootstock.

[0090] Further, the preferred tree pit has a diameter of 70cm and a depth of 60cm.

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...
