Embodiment 1

[0028] Step (1) Ear picking is carried out on the mother tree marked "Youshu 1", and the collection is carried out in January of each year. The branches of the year with a thickness of 0.5cm are collected and trimmed to a length of 50cm. Every 50 branches are one Bundles are bundled, both ends of the spikes are wax-sealed, wrapped with wet cloth and plastic film, and stored in a cold storage at 1°C;

[0029] The rootstock of step (2) is to select a single-dry hackberry with a meter diameter of 3 cm, cut horizontally at 2 m to perform high-level grafting, and select different orientations to graft 2 scions by means of skin grafting;

[0030] Step (3) When the spikes germinate to 50cm, insert a bamboo pole with a height greater than 3m at the root of the tree, choose a branch with a greater tendency to grow upwards as the trunk and bind it to guide its upward growth, while other sprouts Carry out pruning, thin out too much too dense shoot, keep the branch density even, carry out...

Embodiment 2

[0034] Step (1) Pick ears on the mother tree marked "Youshu 2", and collect them in January every year. Collect the branches of the year with a thickness of 0.8cm, and trim them to a length of 80cm. Every 80 branches are one The bundles are bundled, the two ends of the spikes are wax-sealed, wrapped with wet cloth and plastic film, and stored in a cold storage at 3 degrees Celsius;

[0035]The rootstock of step (2) is to select a single-dry hackberry with a meter diameter of 4cm, and cut it horizontally at 2m for high-level grafting, and select different orientations to graft 3 scions by means of grafting;

[0036] Step (3) When the spikes germinate to 50cm, insert a bamboo pole with a height greater than 4m at the root of the tree, choose a branch with a greater tendency to grow upwards as the trunk and bind it to guide its upward growth, and at the same time, other sprouted branches Carry out pruning, thin out too much too dense shoot, keep the branch density even, carry out...

Embodiment 3

[0040] Step (1) Pick ears on the mother tree marked "Youshu 2", and collect them in January every year. Collect the branches of the year with a thickness of 1 cm, and trim them to a length of 100 cm. Each 100 branches is a bundle Bundle, seal the two ends of the spikes with wax, wrap them with wet cloth and plastic film, and store them in a cold storage at 5 degrees Celsius;

[0041] The rootstock of step (2) is to select a single-dry hackberry with a meter diameter of 5 cm, cut horizontally at 2 m for high-level grafting, and select different orientations to graft 4 scions by means of grafting;

[0042] Step (3) When the spikes germinate to 70cm, insert a bamboo pole with a height greater than 5m at the root of the tree, choose a branch with a greater tendency to grow upwards as the trunk and bind it to guide its upward growth, and at the same time, other sprouts Carry out pruning, thin out too many too dense shoots, keep the branch density even, carry out short cutting to mo...

Abstract

The invention discloses a method for cultivating large greening seedlings of celtis tetrandra f. pendula, and belongs to the field of cultivation of saplings of celtis sinensis. The method is used for solving the common problems of small plants, lack of trunks, small crowns and no layers in the existing greening seedlings of the celtis tetrandra f. pendula. Wherein a scion is obtained by selecting a tree with an obvious branchlet weeping characteristic as a scion-picking seed tree, a rootstock is a single-trunk celtis sinensis with a larger specification, the single-trunk celtis sinensis is subjected to high-position grafting, the trunk is bound by using an auxiliary, the trunk is lifted year by year, the layers are cultivated, auxin is sprayed to the tree body after lateral branches are trimmed each time, and sufficient fertilizer is applied in the growing season and the dormant season. According to the scheme, the celtis tetrandra f. pendula saplings with obvious trunks, tall and big tree shapes, elegant branchlets, full crown shapes and short seedling culture period can be cultivated.

Description

[0001] A kind of cultivation method of weeping hackberry greening big seedlings technical field [0002] The invention belongs to the field of cultivating hackberry seedlings, and in particular relates to a method for cultivating large weeping hackberry green seedlings.
