Problems solved by technology

It is difficult to propagate juniper by sowing, the main reasons are: juniper has low seed setting and many empty seeds; seeds have a long dormant period and difficult to germinate; seedlings are not uniform, the survival rate is low and growth is slow, and the pre-sowing seed treatment process is not easy to master ; Sowing seedlings are prone to variation, and the tree shape is easy to fork after becoming useful, which seriously affects the ornamental value of juniper
Similarly, the survival rate of juniper by cuttings is relatively low, so it is not suitable for the production of juniper seedlings.

Embodiment 1

[0023] The first step is to choose an anvil;

[0024] Select to grow vigorously, and the sand cypress that does not have disease and insect damage is as rootstock tree, selects the 1 year old sand cypress branch that grows well on rootstock tree as rootstock;

[0025] The second step is to select the scion branches;

[0026] At the beginning of March, choose juniper with excellent crown shape as the mother tree, and pick 1-year-old branches on the mother tree with a length of 10 cm and good growth as the scion branches; collecting the scion branches requires a special person to be responsible, and carefully record the corresponding cards of the mother tree and the scion; The picked scion branches are put in a cool place in time and stored by wrapping them with damp cloth, 50 branches are tied into a bundle, and the collected scion branches are placed in a refrigerator at 3 degrees Celsius for refrigerated use.

Abstract

The invention provides a method for grafting juniper berry breeding seedlings by means of a sabina vulgaris. The method includes the steps that (1) a sabina vulgaris branch growing for one to two years is selected from the sabina vulgaris which grows vigorously and has no plant diseases or insect pests to serve as a stock branch; (2) a branch of a well-capped juniper berry is cut off to serve as a scion branch; (3) needle-point leaves of a scion cut section are picked off, the scion branch with needle-point leaves is obliquely cut with a cutter blade from the lower side to the pith and then is cut to the tail end in the tail end direction of a scion so that the cut surface can be in a semi-cylinder shape, and a base portion is cut to be in a tongue shape at last to obtain the scion; (4) the portion which is 15-20 cm away from the base portion of the stock branch in the branch direction serves as a grafting cut, a pith forming layer attachment grafting method is adopted, and a scion cut surface is attached to a stock branch cut surface in time and is bound tightly from bottom to top with a film strip; (5) watering is carried out periodically, and cut surface healing is facilitated; (6) after the scion is successfully grafted and grows for one year, the stock branch with a live scion seedling is cut for cottage, and accordingly the seedling is obtained. The survival rate of seedlings cultured in the method is high, and large-scale production of juniper berry nursery stocks can be achieved.

Description

technical field [0001] The invention belongs to the technical field of plant seedling cultivation, and in particular relates to a method for grafting juniper cypress to breed seedlings. Background technique [0002] Juniperus rigida (Juniperus rigida Sieb, et Zucc) is an evergreen small tree belonging to the family Cupressaceae. It likes a cool climate and is resistant to cold and poor soil. In addition, the juniper tree is tall and straight, with a beautiful tree posture, and has high garden ornamental value. It is a rare greening tree species in northern my country. It is difficult to propagate juniper by sowing, the main reasons are: juniper has low seed setting and many empty seeds; seeds have a long dormant period and difficult to germinate; seedlings are not uniform, the survival rate is low and growth is slow, and the pre-sowing seed treatment process is not easy to master The sowing seedlings are prone to variation, and the tree shape is easy to fork after becoming ...
