Embodiment

[0021] Cultivate Podocarpus saplings with a trunk diameter of 1-1.5cm for grafting. During the process of cultivating Podocarpus saplings for grafting, bend the trunk of Podocarpus below 50cm to shape. During the grafting process, use the curved section for grafting. The Podocarpus saplings are grafted with the Podocarpus rootstock trunk in an oblique direction. Such as figure 1 Shown: in the process of cultivating Podocarpus seedlings, in February to April, dig up the Podocarpus saplings 2 for grafting, keep the root system of the Podocarpus saplings 2 for grafting, and put the large-diameter Podocarpus pine trees whose tree diameter meets the expected requirements. Cut the stem into sections, and saw the two ends flat to make the rootstock trunk 1; first open 2 to 7 longitudinal wedge-shaped slots at the lower end of the sectioned Podocarpus rootstock trunk, the longitudinal wedge-shaped slots expose the xylem, and the depth of the wedge-shaped slots is for grafting. 52% to...

Abstract

A method for cultivating podocarpus macrophyllus seedlings comprises the following steps that podocarpus macrophyllus seedlings used for grafting are cultivated, wherein the trunk diameter of the podocarpus macrophyllus seedlings is 1-1.5 cm; the podocarpus macrophyllus trunks with the tree diameters meeting the expected requirement are cut into sections, and the two ends of the trunks are sawn flatly to be used as stock trunks; tree roots are grafted; two or more longitudinal wedge-shaped long openings are formed in the lower end of each stock trunk, the podocarpus macrophyllus seedlings used for grafting are dug, the roots of the podocarpus macrophyllus seedlings are kept, the portions, close to the root portions within the range of 30-50 cm, of the trunks and the crowns of the seedlings are cut off, grafting portions are cut to be in the shape matched with the wedge-shaped long openings, a grafting film is used for bundling after grafting, and the seedlings are reinforced and fixed; the two ends and the grafting portion of each stock trunk are respectively coated with a layer of wound film coating agent, and a layer of protecting film is wound on the portion 20 cm below the top end of each stock trunk; the stock trunks which are processed by the above steps and are grafted with podocarpus macrophyllus tree roots are planted in soil, the stock trunks are supported and fixed, a sunshelter is built, and daily cultivation management is conducted. The podocarpus macrophyllus seedlings are cultivated for half a year, the protecting films are taken apart, the sunshelter is dismounted, and daily cultivation management is conducted.

Description

technical field [0001] The invention relates to the technical field of landscaping seedling cultivation, in particular to a method for cultivating Podocarpus pine seedlings. Background technique [0002] At present, with the continuous progress of society, the urbanization process is accelerating, and people's material and cultural levels are also improving. Various garden constructions in urbanization construction have been favored by the public, and garden construction mainly relies on various An ornamental tree. It takes decades or even hundreds of years for various trees in nature to grow to form its unique ornamental value and value. Existing plant trees with ornamental value are few and far between, extremely rare and extremely expensive. Furthermore, these rare ornamental plants all grow in remote areas, not where people need them most. In order to solve actual or potential environmental problems, coordinate the relationship between human beings and the environment...
