Embodiment 1

[0032] A. Rootstock selection: choose bamboo willow cutting seedlings or plantation seedlings with a height of more than 3m, a breast diameter of more than 2cm, strong growth, and no damage by diseases and insect pests as the rootstock for grafting steamed willow.

[0033] B. Collection of scions: Since bamboo willows are used as rootstocks to graft steamed willows, the survival rate is high, so the scions of steamed willows are grafted as they are harvested, and the scions do not need to be sealed with wax or other treatments. Just two hours before grafting, cut the annual branches of Mantou willow with full buds, strong growth, and a thickness of 0.6cm-1cm from the Mantou willow tree of pure variety, strong growth, and no damage from diseases and insect pests as scions, and immerse them in the base at any time. In the clear water bucket prepared in advance to maintain the vitality of the scion.

[0034] C. Grafting: Grafting adopts the cutting method, and the specific operat...

Embodiment 2

[0040] The difference from Example 1 is that grafting adopts subcutaneous connection and the specific operations are as follows:

[0041] (1) Cut the scion: The scion is usually 5-8cm long and has 3-4 buds. The lower part of the scion cuts a long 3cm long bevel, which requires smoothness and smoothness, and the depth reaches 1 / 2 of the xylem.

[0042] (2) Rootstock treatment: Cut the rootstock at a distance of 2.8-3m from the ground, flatten the cut surface of the rootstock, and choose a place with thick, smooth, and smooth texture to cut vertically along the bark, with a length of 3-3.5cm and a depth of xylem. .

[0043] (3) Grafting: The large cut surface of the scion is inward, and the scion is inserted from the center of the cut, and the scion is inserted to a distance of about 0.3cm from the cut surface of the scion.

[0044] (4) Binding: wrap all the joints tightly with plastic strips, so that the wound cannot be exposed, and the scion and rootstock are tightly bound. ...

Embodiment 3

[0047] Embodiment 3, the nursery stock grafted to embodiment 1 and embodiment 2 is managed after grafting, and concrete process is as follows:

[0048] (1) After grafting, pour water in time, and check the survival rate after 8 days. If the survival rate is low, you can carry out grafting work.

[0049] (2) Ventilation and bag removal: After 5-7 days of grafting, the survival rate can be checked. After the scion germinates, small openings should be torn on both sides of the top of the plastic bag to prevent the new shoots from being burned due to high temperature. The rootstock is fully healed, and when the new shoot grows to about 5-8cm, remove the set plastic bag after 6:00 pm on sunny days or rainy days.

[0050] (3) After the grafting survives, wipe off the buds that germinated on the rootstock in time, and release the binding materials after 60-70 days. Strengthen field management, pay attention to monitoring of diseases and insect pests, and do a good job in management ...

Abstract

The invention discloses a method for quickly a cultivating steamed bread willow by taking a bamboo willow as tree stock. By the method, a problem that a traditional steamed bread willow propagation method has the high cultivating cost is solved. The method comprises the following steps of: A, selection of tree stock, selecting healthily-growing bamboo willow cutting seedlings or inserted-bar afforestation seedlings with heights above 3m and breast diameters above 2cm and without plant diseases or insect pests as the tree stock for grafting the steamed bread willows; B, grafting and collecting, grafting the steamed bread willow along collection, and cutting off annual branches of the steamed bread willow with plump buds, strong growth and roughness of 0.6cm-1cm; C, grafting the steamed bread willow by a crown grafting or cut-grafting method; D, managing after grafting. In the method, the bamboo willow is taken as the tree stock and is used for grafting and cultivating the steamed bread willow, so that a cultivating period can be greatly shortened, a cultivation cost is reduced, large seedlings are quickly cultivated and the economic benefit of a nursery garden is increased.

Description

technical field [0001] The invention belongs to the field of garden plants, and in particular relates to a method for quickly cultivating steamed willow. Background technique [0002] Mantou willow is very popular because of its soft branches, plump crown and beautiful tree shape.
